00:00:00.000 Hey for the wild community, I wanted to let you know that we had a follow-up call with Dr. Chad
00:00:05.060 Hansen last night about the current fires raging in California right now. So stay tuned after the
00:00:11.560 show and you'll be able to hear some extra questions with Dr. Chad Hansen. Now on to the show.
00:00:17.660 In the era of climate change, and when we have such threats to biodiversity, we have
00:00:33.520 to recognize that there is a growing consensus among the scientific community, nationally
00:00:37.480 and globally, that in order to avert, in order to avoid the very worst effects of climate
00:00:43.280 change. We need to not only move beyond fossil fuel consumption, we need to also dramatically
00:00:50.460 increase forest protection and pull a bunch more CO2 out of the atmosphere. And that's the only
00:00:56.480 way we're going to get there. We can't not get to our climate change mitigation goals just by
00:01:00.840 moving beyond fossil fuel consumption alone. We have to do that, but it's necessary. It's
00:01:05.740 not sufficient. We also have to protect our forests and increase forest protection.
00:01:13.280 Hello and welcome to For the Wild podcast. I'm Ayanna Young. Today we are speaking with Chad
00:01:29.760 Hanson. Chad is a research ecologist with the John Muir Project of Earth Island Institute,
00:01:35.860 located in Big Bear City, California. He is also a member of the Sierra Club's National
00:01:41.580 Board of Directors, elected in 2018. Chad has a PhD in ecology from the University of California
00:01:48.660 at Davis, with a research focus on fire ecology in conifer forest ecosystems, and he is the co-editor
00:01:55.740 and co-author of the 2015 book Nature's Phoenix, The Ecological Importance of Mixed Severity Fires.
00:02:05.020 Studies published by Dr. Hansen covers topics such as habitat selection of rare wildlife species
00:02:11.240 associated with habitat created by high severity fire, post-fire conifer responses and adaptation,
00:02:18.480 fire history, and current fire patterns. Well, welcome Chad. We're so excited to speak with
00:02:25.160 you today about all of this research and topics that you cover. Thank you. So I want to start
00:02:30.740 off by speaking to the fact that indigenous peoples across Turtle Island have long tended
00:02:36.280 fires to increase biodiversity, recognizing fire as being an actual vital part of ecosystems.
00:02:44.420 However, dominant society today has a very different approach when it comes to the tending
00:02:49.740 of fires and the stories that are told about them. This was glaringly apparent this past year
00:02:55.400 as the mainstream news covered wildfires in the United States, emphasizing their presence as
00:03:01.540 inherently catastrophic. So I'd like to begin this interview by inviting you to share some
00:03:07.360 historical context on how we arrived at this point, where dominant society insists on the
00:03:13.360 quenching of fires and continues to perpetuate a serious cultural misunderstanding of fire.
00:03:19.660 Well, that's a great question. Native Americans have understood the importance of fire in forest
00:03:25.920 ecosystems and other ecosystems for thousands of years in North America. And there's a deep
00:03:32.900 understanding there about the role of fire in creating certain types of vegetation, producing
00:03:38.960 and maintaining certain types of berry-producing plants, trees that produce acorns and food,
00:03:46.380 creating habitat that large mammals prefer that might be good for hunting. This has been
00:03:51.560 understood for a very, very long time. So, you know, for many, many thousands of years,
00:03:55.920 millions of years, actually, fires occurred on in the forests of North America and around the world. 1.00
00:04:01.420 And with regard to the last several thousand and more years, Native Americans have started fires 0.64
00:04:08.640 and fires have been started by lightning. And so, you know, in the past, you know, 15,000 years, 1.00
00:04:14.340 and to the present in particular, you know, fire has been a combination of Native American burning 0.59
00:04:18.820 and lightning strikes for a very, very long time. And this is what the biodiversity in our forest
00:04:25.600 depends on. There are many, many species in the forest, plant and animal, that actually can't
00:04:29.860 survive without the habitat that's created, the unique habitat created by fire. But really in
00:04:36.800 starting, especially in the gold rush era, the settlers viewed fire as something that destroyed
00:04:43.440 what they saw as a timber commodity resource. And so they were really looking at the forest
00:04:47.460 from an economic standpoint. And they saw fire as the enemy because it was
00:04:51.960 killing something that they wanted to cut down and sell and use for lumber.
00:04:56.940 Yes, I remember actually, in my fire ecology class that I took a few years ago, we talked about
00:05:04.120 Smokey the Bear. I think it's Smokey the Bear and just the rhetoric and even this cartoon story to
00:05:11.800 get people to really protect the timber industry. And I think even it was maybe perhaps the timber
00:05:18.220 industry that was behind Smokey the Bear, although I think it's also with the US Forest Service. But
00:05:22.860 again, the US Forest Service sells contracts to timber companies. So it's really important for us
00:05:30.120 to look at why this culture is trying to, quote unquote, protect against forest fires. And thank
00:05:38.480 you for bringing that up. The next thought I was having was that, you know, I think about
00:05:42.440 ponderosa pine and lodgepole pine, for example, and they've evolved over thousands of years to
00:05:48.140 live in harmony with fire. Today, the cones pop open and set seeds through intense heat.
00:05:54.000 And then I think about morel mushrooms, you know, they're another example in which heat stimulates
00:05:58.020 the spreading of its spores. So I'd like to know what are some other examples of how
00:06:02.900 high-intensity fire patches support the highest levels of biodiversity in the Western United
00:06:08.380 States? And how is this a part of the forest community really coming together and rebounding
00:06:14.680 from fire? And I guess another question in that vein is, what happens to these ecosystems when
00:06:21.200 humans intervene and try to suppress intense fires? Yeah, those are great questions. So in
00:06:26.780 order to sort of get into that, we need to first, I think, dispel some of the common mythology
00:06:31.580 about fires, especially large wildland fires and high intensity fire patches, because we hear a lot
00:06:38.240 of misinformation out there in the public dialogue, a lot of it from politicians, especially those who
00:06:44.200 get a lot of campaign contributions from the logging industry. We also hear it from the United
00:06:48.400 States Forest Service, especially under the Trump administration. As you mentioned, the U.S. Forest
00:06:53.800 Service is in the commercial logging business. They sell public timber to private logging companies
00:06:58.080 and they keep most of the revenue for their budget.
00:07:00.920 So they have a financial incentive.
00:07:03.560 And everything involved in this logging is sort of wrapped up in the fire issue.
00:07:09.280 Basically, the proponents of logging on national forests and other forests are saying that
00:07:15.320 they need to log the forests supposedly to curb fire and stop fire.
00:07:20.480 And it doesn't really work that way.
00:07:22.860 Fire is driven mostly by weather, not by the density of the forest.
00:07:25.820 And oftentimes, actually, the areas that have had the most logging tend to burn the hottest.
00:07:30.920 So logging doesn't have that effect.
00:07:32.580 But there's a deeper issue here that they're missing with all that rhetoric.
00:07:36.800 And that's that when fires burn, even in those patches where they burn hot and kill most or all the trees, the forests regenerate in spectacular fashion.
00:07:46.400 And that regeneration creates wonderful wildlife habitat.
00:07:49.960 You know, we hear a lot of sort of hyperbolic statements out there that right now the forests are so dense and the fires burn so hot that it sterilizes the soil and nothing will grow.
00:08:01.060 That's pure mythology.
00:08:02.300 It doesn't work that way at all.
00:08:03.620 And in fact, our forests are not more dense now than they were historically.
00:08:07.500 Actually, there's less biomass in our forests now than there was a century ago because of decades of logging.
00:08:14.700 And so, you know, there's a lot of mythology we kind of need to cut through on this.
00:08:17.940 But I'll just talk about, you know, how it really works in the forest when fire burns.
00:08:22.320 So, you know, the first thing that happens after the flames pass and the smoke clears is that there are many, many species, native species of beetles we call wood-boring beetles.
00:08:33.620 And they have evolved over many thousands of years.
00:08:37.220 They've evolved receptors in their bodies to detect fires by heat or by smoke, depending on the beetle species.
00:08:43.720 and they will make a beeline for fire areas because they need recently fire-killed trees
00:08:49.360 in order to reproduce so the beetles they are really good flyers they'll fly from you know
00:08:54.580 from miles away and they'll land on the the charred bark of a fire-killed tree they lay their eggs
00:08:59.880 and the larva develops and bores through the bark into the wood of the fire-killed tree
00:09:04.180 and it develops into an adult over the course of a year two years sometimes three or four
00:09:09.360 years or more and then it emerges as an adult but when it's a larva inside these fire-killed trees
00:09:15.960 when it's in that stage it's food for a number of native woodpecker species that depend on the
00:09:23.740 larva of these wood boring beetles in order to survive and you know dead trees are softer than
00:09:29.520 live trees and so the woodpeckers create nest cavities in these dead trees so for example the
00:09:35.040 blackback woodpecker. It's a species I've been studying for about 15 years now. It's a monogamous
00:09:40.000 species. And every spring, the male will create between two and four nest cavities. And the female
00:09:45.840 picks the one she likes the best. And that's where they raise their young that year. But all the other 0.56
00:09:50.320 nest cavities that they don't use, those are available for all the other cavity nesting species
00:09:56.320 in the forest that have to have cavities to reproduce and raise their young, but they can't
00:10:01.920 make their own. So for example, bluebirds and nuthatches, wrens, flying squirrels, chipmunks,
00:10:08.400 dozens and dozens of bird and small mammal species need these cavities, but they depend on the
00:10:12.900 woodpeckers to create those cavities in these dead trees for them. And the woodpeckers can't do that
00:10:18.320 unless they have dead trees and the beetle larva to eat. You can't have that unless you have fire
00:10:23.360 or cycles of drought that kill patches of trees as well. And so you end up having this very,
00:10:29.440 very rich and interconnected ecosystem that provides food and habitat for all kinds of
00:10:34.800 species. But the other thing that happens is shortly after a fire, especially where it burns
00:10:39.300 hotter and kills more trees, is it stimulates the growth of all kinds of fire-following plants
00:10:45.480 that have evolved to depend on intense fire to basically spur their germination. And a lot of
00:10:52.560 these are flower-producing plants, wildflowers and flowering shrubs. And they attract native
00:10:58.200 flying insects and that provides food for fly catching birds and bats and the shrubs and the
00:11:05.800 natural regeneration of conifer seedlings and oak seedlings that come in and the dead trees that
00:11:11.500 fall all that understory vegetation and complexity provides great habitat for small mammals and
00:11:18.080 because of all the small mammals and all the birds in the forest that also provides food for raptors
00:11:24.380 owls and hawks. And a lot of the berry producing plants are great for the bears to get fat on
00:11:30.720 before the winter. And so you end up having an ecosystem that is incredibly biodiverse. And in
00:11:37.180 fact, interestingly, the areas that burn hottest, where most or all the trees are killed, those
00:11:42.520 patches that represent typically 20 to 25, sometimes 30 percent of the area that burns in a
00:11:49.760 forest. Those areas, we call that snag forest habitat, those areas that burn hotter. And that's
00:11:55.240 actually comparable to old growth forest in terms of native biodiversity and wildlife abundance. So
00:11:59.700 it's actually an ecological treasure, not a disaster.
00:12:03.280 That is so interesting to really break down these myths and truly understand fires from an ecological
00:12:11.340 standpoint. I want to get into that even more. But before we do, I'm wondering, is it beneficial or
00:12:18.340 how beneficial is it to seed or plant trees after these high-intensity fires? I'm wondering,
00:12:25.220 does that speed up the process? Or is it more about that the high-intensity fires uncover
00:12:30.440 seeds that have been resting in the soil for long periods of time? What is the best way to
00:12:35.180 look at restoration of these burned areas, if that's even beneficial at all?
00:12:41.940 Right. So going back to your question earlier about what does it mean when humans intervene
00:12:46.600 after a fire. The bottom line is this. Basically, hundreds of scientific studies have been published
00:12:52.540 on these issues. And what they're really telling us loudly and clearly is that the best thing you
00:12:57.180 can do after a fire is absolutely nothing from an ecological standpoint. Now, if you have a dead
00:13:03.140 tree that could fall on a house, then you need to cut that dead tree down because that's a public
00:13:07.880 safety issue. But from an ecological standpoint, from purely forest ecology, you don't need to do
00:13:14.200 anything. You don't need to replant. You don't need to cut trees down. The forest regenerates
00:13:18.160 all on its own, just naturally, even in the largest patches of high-intensity fire.
00:13:22.560 The areas where dead trees, you have nothing but dead trees across hundreds of meters
00:13:27.080 of ground, those forests regenerate beautifully. I just published a study on that very issue.
00:13:33.800 The reason is it's not just about how close to a given area live trees are. It's also about
00:13:39.320 the birds and the small mammals distributing seed source all over the forest. So, you know,
00:13:45.360 in some cases, there are certain conifer species, certain tree species that depend on intense fire
00:13:51.480 to melt the resins in their cones and to release their seeds. Giant sequoia is one of those
00:13:56.720 species. For example, Rocky Mountain Lodge pole pine, knob cone pine, there are a number of them,
00:14:01.560 but there are also a lot of species that have other adaptations and they depend on intense fire or,
00:14:08.020 you know, even low and moderate intensity fire to create the conditions that allow new trees to
00:14:13.120 regenerate. And they regenerate beautifully. But the reality is this, is that in some places,
00:14:18.380 the regeneration of the trees is going to be very, very dense and very quick. And in other places,
00:14:22.880 it's going to be more open and it's going to be more oak and shrub dominated with more
00:14:26.860 scattered conifer trees regenerating. Both of those things are good. And that's what we need
00:14:32.160 to understand. It's not a cookie cutter approach. In nature, you want that kind of variety. You
00:14:37.820 want that what we call heterogeneity. And we get that after fire. We get these natural varied
00:14:44.420 patterns of regeneration in that mosaic, including in the biggest high-intensity fire patches.
00:14:50.460 And that's good because certain species want different things. And if you're just doing
00:14:55.100 one type of thing, which is what they do when they cut down the fire-killed trees and artificially
00:15:00.720 plant trees in these post-fire logging operations after fire, you know, they basically plant for
00:15:06.420 250 or 300 trees per acre. And what you get is a sterile, ecologically diminished area,
00:15:14.080 basically a tree plantation. And it's really just a crop. It's not a forest ecosystem.
00:15:19.340 So basically what they've done is removed the forest. And I think what we need to get to
00:15:23.600 is an understanding that a forest ecosystem is not just the areas of mostly live green trees
00:15:30.680 that haven't burned in a long time or have burned more recently at low and moderate intensity,
00:15:35.420 where most of the trees survive. And that's what most fire is. Even the biggest fires
00:15:39.580 are mostly low and moderate intensity, but there are significant high intensity fire patches. And
00:15:44.620 the question is, what does that mean? And we have to understand that now there are hundreds of
00:15:50.620 scientific studies that are telling us those high intensity fire patches create another forest
00:15:55.160 habitat type that wasn't recognized historically. This is what we call snag forest habitat. And it's
00:16:00.760 just as important as old growth forest in terms of, you know, wildlife diversity and abundance.
00:16:06.640 And we need to recognize that. And so it's not a matter of restoring the forest after the fire.
00:16:12.100 It's a matter of recognizing that the fire actually is the restoration.
00:16:30.760 Thank you.
00:17:00.760 Thank you.
00:17:30.760 Thank you.
00:18:00.760 to hear that after a fire there's a plethora of biodiversity as much or close to an old growth
00:18:10.500 forest it's really interesting to wrap my mind around that concept and i guess part of me is
00:18:16.380 thinking okay a high severity fire is a large disturbance and that disturbance actually like
00:18:23.340 you were saying creates biodiversity but how does that differ from let's say clear-cutting which is
00:18:29.300 also a large disturbance you know i know in a sense yeah there won't be the snags but i'm trying
00:18:36.400 to see like how to explain this question that's coming up in my mind is so if if large high
00:18:43.740 severity fires are creating disturbance that creates ecological diversity but clear cutting
00:18:49.960 is also a large disturbance but destroys biodiversity could you kind of explain the
00:18:56.520 difference between the two? I know that may seem really simple, but there's, I don't know,
00:19:00.780 there's something in that question that feels important. It is. It's actually a very good
00:19:04.840 question. And I think it's important because in the 20th century, foresters, the logging industry,
00:19:12.360 the Forest Service, they basically equated an area that burned at high intensity in a fire
00:19:17.920 with a clear cut. They would call it early successional or early sterile forest.
00:19:22.700 and scientifically we now know that that is completely wrong nothing could be further from
00:19:28.200 the truth the two conditions are completely opposite and bear no relationship to each other
00:19:33.660 and i'll explain why in a fire as i said you know most areas even in the biggest fires mostly what
00:19:39.940 they are is low and moderate intensity where you have most of the live mature trees survive but
00:19:45.660 you have patches that can represent 10 of the total fire area sometimes 30 or 40 but usually
00:19:51.340 in that 20-25% range that are high-intensity fire. And those areas are basically dominated by
00:19:59.840 fire-killed trees, what we call snags, those standing dead trees, and also all the understory
00:20:07.420 vegetation that grows in, the shrubs, the oaks, the conifer regeneration, in different ways in
00:20:14.840 different locations. When you have a clear cut that removes all of that structure, all of that
00:20:21.740 habitat, and all you have is just rows of planted trees, little trees grown in nurseries, planted
00:20:29.340 all the same age, you don't have the things that wildlife need to survive and reproduce.
00:20:36.220 So, you know, as I mentioned, a forest ecosystem is not just mature green trees. That's one of
00:20:41.640 about six or seven key structural components of a forest ecosystem. To have a forest and to have
00:20:47.780 all the biodiversity in the forest, you also need the small understory trees, the oaks, the conifers,
00:20:52.940 the dogwoods, the aspens. You also need the dead trees, the snags. You need the down logs. You
00:20:59.140 need the shrubs and the wildflowers. What clear cutting does is it removes all of that. And
00:21:05.260 frankly, what thinning does, what people hear, they hear the word thinning a lot and they think
00:21:11.000 of it as the Forest Service out there with pruning shears. But in reality, thinning is a very, very
00:21:15.560 intensive and very damaging industrial logging operation the vast majority of the time. And
00:21:21.240 they're removing, killing and removing upwards of 70% of the trees in a given stand, including
00:21:26.720 mature and old growth trees. And basically what you have in those mechanical thinning areas is
00:21:32.080 just these kind of widely spaced, live, mature trees, but almost nothing else. The understory
00:21:37.500 is basically gone. The snags are mostly gone. The down logs are gone. The shrubs are gone.
00:21:43.500 And so, you know, especially in clear cutting, but also to a large extent in these areas that
00:21:48.140 where mechanical thinning has occurred, most of what actually defines a forest ecosystem
00:21:53.480 has been removed. Whereas in a fire, especially in those patches where it burns hot, you actually
00:22:00.940 have creation of a particular type of habitat, a unique habitat, this snag forest that is very
00:22:08.000 structurally complex and has all these different habitat elements, the snags, the down logs,
00:22:15.280 the regenerating conifer seedlings and saplings, the pockets and patches of native shrubs that
00:22:21.960 the shrub nesting birds and the small mammals like so much, the patches of snags that the
00:22:26.760 woodpeckers and all the cavity nesters need. All of that is there. And so that's why it's so rich
00:22:33.060 in biodiversity. But a clear cut is basically the act of removing all of that habitat. And so
00:22:40.180 honestly, from an ecological standpoint, a clear cut is closer to a parking lot than it is to
00:22:45.940 a patch of snag forest created by high intensity fire.
00:22:49.780 Thank you so much for explaining the difference between those two things. Because although
00:22:54.660 I understood somewhere in my mind that they are very different. I think that, again, there's a lot
00:23:01.120 of rhetoric about how they're somewhat similar. And it's really interesting to hear the complexities
00:23:08.880 of the myths that were told, especially around thinning. And thinning has been this question
00:23:14.800 mark in my mind for so long, because in a sense, I hear you had said that there's actually less
00:23:20.360 biomass in the forest now but in a sense they're more crowded because of the way that timber
00:23:26.180 companies have replanted plantation forests like instead of you know and I always imagine it instead
00:23:31.580 of looking at a forest or a plantation as a forest it's almost like a field of corn but it's just
00:23:37.640 usually dug furs instead of a corn crop and that absolutely has very little biodiversity much of
00:23:44.760 the time, those clear cuts are actually poisoned with insecticides and fungicides and trying
00:23:51.780 to kill other plants out so that the crop tree, usually the dug for conifer, the ponderosa
00:23:56.920 pine, the Sitka spruce, cedar will grow back.
00:24:00.260 So it's a really interesting investigation to start looking into when you really start
00:24:06.320 seeing the truth behind large scale logging operations.
00:24:10.460 And I want to get into that more, especially with the politics behind it.
00:24:13.240 But before we go there, I wanted to talk a bit more about some of the impacts of fires.
00:24:19.380 So I think about the general consensus is that predicted future climates will greatly
00:24:25.140 increase fire frequency.
00:24:26.460 So we're really looking at more fires, you know, the extent, the severity.
00:24:30.800 And I have a few questions here of like, one, I'm wondering, how will this change common
00:24:35.480 vegetation?
00:24:36.660 Will areas traditionally dominated by, say, shrubland and chaparral transition to grasslands?
00:24:41.920 You know, how will this change impact species composition in areas like California?
00:24:47.260 And then I think a second part to that question is the question of drought and how drought, which is most likely eminent in the near future.
00:24:56.580 And I mean, we're already in it, especially in places like California and honestly, the whole Pacific Northwest.
00:25:02.180 How is drought going to affect regrowth after fires?
00:25:05.780 Does it become increasingly difficult for the earth to regenerate during periods of drought?
00:25:10.480 Yeah, all good questions.
00:25:11.920 So, I mean, I think to have a good conversation about the influence of climate change and
00:25:17.260 fire, we really need to kind of decouple those two things because climate change influences
00:25:22.020 fire, of course, and it's influencing it right now and will continue to do that.
00:25:26.860 At the same time, they have very, very different effects because the main threat from climate
00:25:33.480 change, in my view, is rising temperatures and that can cause shifts in vegetation patterns
00:25:40.760 And it can cause shifts in patterns of where vegetation grows, where it regenerates.
00:25:45.940 And oftentimes the fire and climate change get conflated into the same conversation.
00:25:51.080 They really need to be treated separately because what I'm seeing is that when fires
00:25:54.760 are occurring, you're getting this wonderful regeneration, this rejuvenation of the forest
00:26:00.380 ecosystem and other ecosystems, woodlands and grasslands, lots of different ecosystem
00:26:05.800 types, but especially forests.
00:26:08.340 And if anything, I'm actually seeing fire as an agent of maintaining vegetation types in a given area and rejuvenating those stands.
00:26:16.940 I see the threat from climate change, from human caused climate change to our forests as being primarily about rising temperatures and possibly as well, drought cycles related to climate change.
00:26:27.720 But a couple of things need to be understood in this context.
00:26:30.440 First of all, we have a substantial deficit of fire in our forests currently, and that's not something that most people understand. I mean, it's well understood within the scientific community. It's not well understood among the general public or among policymakers.
00:26:46.560 But this is an interesting thing because the fact is, is that there is no dispute in the scientific community about that fact. What people disagree about, what they debate all the time, what they fight about is how much less fire we have now than we had historically. Is it half as much? Is it one seventh as much? Is it somewhere in between?
00:27:08.680 But there's a broad consensus that we have a deficit of fire and basically a deficit of all intensities, low, moderate and high in our conifer forest ecosystems.
00:27:17.320 So we need to understand that because the reality is, from an ecological standpoint, we don't want too much fire and we don't we don't want too little.
00:27:25.980 Right now, we actually have too little.
00:27:28.280 So there are a number of models that are predicting that we'll have more fire in the future because of human caused climate change, because of increasing temperatures, which can influence fire.
00:27:38.100 because of drought cycles, which can influence fire. There are other climate models that predict
00:27:43.820 it's going to be a complex mix of regional or localized increases and localized or regional
00:27:50.160 decreases in fire because of the combination of rising temperatures in some areas in combination
00:27:56.420 with drier conditions and rising temperatures in other areas in combination with wetter conditions.
00:28:02.600 So whether you have hotter, drier conditions or warmer, wetter, that makes a big difference in
00:28:07.780 terms of what you can expect with regard to future fire effects. So we may get a complex mix. There
00:28:14.040 are a number of studies predicting that. And there are other models that are predicting widespread
00:28:17.980 decreases in fire, especially high-intensity fire, in the future. Even if we might have a
00:28:24.160 short-term increase in the near-term decades, overall it'll decrease. And they're predicting
00:28:31.160 that in a hotter, drier future on the basis of predicted shifts in understory vegetation
00:28:38.300 with ongoing droughts and basically less understory vegetation to carry flames.
00:28:44.500 And honestly, we're not going to know until we get there in the future, which is why it's
00:28:49.260 so important to continue to publish studies on existing trends, where things are going
00:28:55.200 right now, where they've gone since 1984, which is our earliest data from satellite
00:29:00.680 imagery that allows us to track fires and fire intensity. And I've published some work on this
00:29:05.340 and I'll continue to do that. So it's really important that we actually publish information
00:29:09.740 on the actual existing trends and patterns. What we're seeing from those is that we
00:29:16.840 have an overall incremental increase in the annual acres burned. So the total area that
00:29:24.560 burns in fire in a given year is sort of incrementally increasing and has been for
00:29:29.640 a number of decades. We still have a lot less now than we had historically, but it is increasing.
00:29:34.180 But interestingly, what the great majority of the studies, including my own, show is that fire
00:29:40.580 intensity is not going up. So even as the area that burns in a given year is starting to get
00:29:48.120 inch by inch every year, a little closer to historical norms that occurred before fire
00:29:54.240 suppression, the fires are not getting more intense, which was one of the biggest concerns
00:29:59.280 or fears for a long time that if fire increases, it's going to increase also in intensity. But
00:30:05.220 we're not seeing that. We need to keep looking at it, though.
00:30:08.540 Just to go back to the thought of, and maybe we can't answer this right now, but
00:30:13.700 do you think that drought is going to affect the regrowth after fires? Is that something
00:30:19.640 that you're concerned about? Or do you think that it's just part of evolution and these seeds and
00:30:27.000 shrubs and trees will find another way to capture water. Because I think about, well,
00:30:32.520 potentially after a fire, the soil could maybe even retain more water, kind of thinking about
00:30:38.680 the whole biochar effect. But I also, you know, I wonder about that. As temperatures get hotter,
00:30:45.960 drought gets more permanent. How will it affect the regrowth after a fire?
00:30:52.360 Yeah, I think drought can certainly have an effect on forest growth and forest regeneration.
00:30:58.240 I don't think it's an issue of before or after a fire or whether or not a fire has occurred in a given area or not.
00:31:04.040 I don't think that's the key issue.
00:31:05.140 I think it's rising temperatures from human-caused climate change and possibly exacerbated drought cycles as a result of that,
00:31:12.880 that will affect vegetation and regeneration across ecosystems and across forest types, whether they burned or not.
00:31:19.120 And that's really what I'm getting at is I think what we are concerned about is our shifts in forests upslope and north as a result of increasing temperatures in particular, but also possibly made worse by more intense drought cycles.
00:31:36.580 Now, we've always had droughts, and we've had big droughts. If you go back in the paleoecological record, there are lots of studies on this showing we've had very, very long droughts, sometimes lasting for many years, sometimes decades, sometimes even longer. So that's not a new thing, droughts or big droughts. The question is the frequency of them and the duration. Will that increase beyond historical norms?
00:32:01.520 You know, there's always that possibility and there's a lot of data that still needs to be gathered on that. But there's certainly a number of scientists that are predicting that climate change can make drought cycles worse. That is an issue that poses challenges, risks and threats to forest ecosystems and other vegetation without regard to whether they've burned recently or not.
00:32:22.540 With regard to fire, there's a few things that happen in fire that are different from areas that haven't burned in a long time.
00:32:30.460 One of those things is nutrient cycling.
00:32:32.440 Basically, what that means is fire takes all of those twigs and branches and pine needles and leaves on the forest floor that have enormous amounts of important nutrients in them that are locked up in basically unusable forms in that woody material on the forest floor, what we call duff and litter.
00:32:53.580 And fire, especially patches of more intense fire, they turn that into a nutrient rich bed of mineral ash. And that rich bed of mineral ash spurs the growth of the forest for decades to come after a fire occurs.
00:33:12.000 So it's really important to understand that because, again, what I'm seeing right now is that we're seeing significant and very vigorous forest regeneration of conifers, of oaks, of shrubs, of all kinds of vegetation in these areas that are burned,
00:33:31.060 including in the largest fires and even in the interior areas of the largest high-intensity fire
00:33:36.500 patches, such as those in the Rim Fire that burned five years ago west of Yosemite. It's a place I'm
00:33:43.260 doing a lot of research, and I published a study on post-fire regeneration in the Rim Fire earlier
00:33:48.420 this year. And what I found was that the regeneration happened, I studied the regeneration in the most
00:33:56.300 severe drought years after the rimfire occurred. And I studied in particular the largest high
00:34:02.020 intensity fire patches. And what I found is that all of these areas are regenerating. I can't find
00:34:07.480 a single acre where the conifer forest is not regenerating in these large high intensity fire
00:34:13.120 patches, so long as they have not been subjected to post-fire logging, which I'll talk about in a
00:34:17.920 minute. But if it's natural regeneration, just left to nature, what I'm seeing is very, very dense,
00:34:24.780 very rapid regeneration, nearer to the live tree edges, basically the low and moderate intensity
00:34:31.240 areas where you mostly have live trees. So closer to those areas, it's somewhat denser. There's more
00:34:37.800 fir and cedar trees. In the interior areas, farther away from live trees, in these bigger
00:34:42.880 high-intensity fire patches, we're getting conifer and oak regeneration too. But it's a little bit
00:34:48.420 more open, which certain wildlife species really like. And it's more pine dominated. So it's
00:34:55.560 possible that drought has played a role there because those were very significant drought years
00:35:00.900 right after the fire occurred. It's also possible these are conifer species that have evolved to
00:35:07.020 sort of take advantage of those spaces. You know, you get more fir and cedar closer to live trees
00:35:12.200 and you get more pine dominated regeneration deeper in the interior of those high intensity
00:35:18.180 fire patches, more open pine dominated, pine and oak dominated forest. And to me, that's all to the
00:35:24.460 good because like I said, different groups of species like different things and depend on
00:35:29.840 different things. Some like those open pine oak forests, some like the really dense fir and cedar
00:35:34.700 dominated forests. And you're getting all of that in the regeneration and the rimfire.
00:35:42.200 these are action points for this episode myths and mismanagement of wildland fires
00:35:55.800 one call your state's u.s senators and congressional representatives at the
00:36:00.600 capital switchboard 202-224-3121 and ask them to one keep the appropriation bill and the farm bill
00:36:08.980 clean, keep all logging provisions off these two bills, and oppose any logging writers on these
00:36:14.120 bills. Specifically ask them to keep the Forest Resilience Bill, or H.R. 2936, off of the Farm
00:36:21.440 Bill reauthorization. Two, ask them to support an end to any logging on National Forest, and commit
00:36:27.500 publicly to saying that they are in support of ending logging on National Forest. If you live
00:36:33.540 in or near a wildfire zone, learn about defensible space. One, keep your chimney clean and screened.
00:36:40.660 Two, keep your storage shed located away from your home. Three, avoid outdoor burning. Recycle
00:36:46.440 mulch and compost when possible. Four, make sure your driveway is accessible and your address is
00:36:51.720 visible. Five, scatter trees within 30 feet of your housing structure. Six, have 100 feet of
00:36:57.900 garden hose attached. Seven, keep wood pile, fuel tanks, and other burnable materials 30 feet
00:37:03.520 away from your housing structure. Eight, thin and prune conifer trees. Nine, keep grass green and
00:37:09.460 mowed if it's within 30 feet. Keep vegetation mowed within 100 feet of your housing structure.

00:38:26.300 I really appreciate your perspective on this. It's such a complicated issue, especially when we mix climate change, drought, industrial scale logging, fires. It's a lot to take in and I really appreciate you breaking it down for us.
00:38:43.260 I want to now talk about this forest carbon plan. And following the wildfires in California this
00:38:50.340 past year, Governor Jerry Brown announced this forest carbon plan, which proposed to use $254
00:38:57.840 million to double logging levels in California forest to at least 500,000 acres a year.
00:39:06.200 So can you share with us why these sort of logging proposals actually leave communities
00:39:11.420 more vulnerable to fires? You know, you've talked about how they harm forest ecosystems and could
00:39:16.660 potentially even accelerate climate change. But also, how do they strengthen the logging industry
00:39:21.180 and threaten existing environmental protections? Well, there's a few different things going on
00:39:28.260 here. And, you know, first off, yeah, there are serious scientific problems with the Brown
00:39:32.680 administration's forest carbon plan. It's not a scientifically sound document, to put it mildly.
00:39:38.140 There are dozens and dozens of scientific studies that we submitted to the administration and other scientists, other organizations that they completely ignored.
00:39:47.400 They misrepresented numerous scientific studies that were cited in the document.
00:39:54.040 And what it all stands for is this, is basically they're proposing a massive increase in logging supposedly to maintain more carbon in our forests.
00:40:03.980 Now, this is completely contradicted by the overwhelming weight of scientific evidence, which indicates that if you remove a bunch of carbon from the forest through logging, guess what?
00:40:14.660 You have less carbon in the forest.
00:40:16.720 You don't actually result in a net increase in forest carbon, even if you assume that the forest management activities that they're doing will curb fire, which it oftentimes doesn't do.
00:40:28.820 But even if you make that assumption, a given area that's logged is so unlikely to burn within 15 or 20 years, there's very, very little chance that an area with, for example, mechanical thinning will even encounter a fire.
00:40:43.300 And so these areas get mechanically thinned again and again and again every 15 or 20 years.
00:40:48.700 And that can happen for 200 years before you even have a 50-50 chance of that stand even encountering fire.
00:40:54.720 So this is a sham, basically, you know, from a climate change standpoint, it's a disaster.
00:40:58.980 It results in a huge net loss of forest carbon storage and a massive increase in carbon emissions from all that increased logging.
00:41:06.780 But it's also a disaster from a community protection standpoint, because what it's doing, it's selling a lie.
00:41:13.380 It's selling a myth to the public saying we're going to double down on logging out in your forests and we're going to somehow protect you from fire, protect the rural homes and communities.
00:41:24.240 from fire by doing all these logging projects out in the forest. What the science is telling us
00:41:29.280 loudly and clearly is that the only effective way to protect homes is to help homeowners make their
00:41:36.440 homes more fire safe. Things like fire resistant roofing, rain gutter guards, so pine needles and
00:41:43.180 dry leaves don't accumulate in the rain gutters where an ember floating on the winds a mile in
00:41:48.220 advance of the flames can land on the roof and roll down into that rain gutter, and exterior
00:41:52.720 your vents so an ember doesn't float into an attic space, things like that. That in combination with
00:41:58.780 what we call defensible space, which is basically removing most of the small trees, shrubs, grasses,
00:42:05.140 and then removing the lower limbs on the mature trees, but leaving those mature trees in place,
00:42:10.720 doing that within 100 feet of homes in combination with these fire state principles for the home
00:42:15.220 itself dramatically increases the odds that a home will survive a wildland fire. And in fact,
00:42:21.400 when this is done properly in communities, what we're seeing now is over 95% of homes surviving
00:42:27.420 fire. The fire, in many cases, is just moving right through the community like water through
00:42:31.680 a sieve, but the vast majority of the homes survive. However, if instead of focusing on
00:42:37.620 home protection and focusing and directing our resources there, where we know it will save homes
00:42:43.280 and save lives, if instead we're doubling down on backcountry logging and backcountry fire
00:42:49.220 suppression and trying to turn back the clock to the mid 20th century, then we're not only going
00:42:53.860 to destroy forest ecosystems and further threaten imperiled wildlife species. We're not only going
00:42:59.060 to exacerbate climate change, but we're going to further threaten communities because you're
00:43:04.700 basically giving people a false sense of security, telling them that this logging project out there
00:43:09.540 way over the ridge somewhere has protected them. And so people think, well, I don't need to do my
00:43:13.960 defensible space. Maybe they don't even know what that is because they weren't told how to make
00:43:18.160 their homes fire safe. So it really is a very dangerous sort of approach. It's a regressive
00:43:25.300 approach. And frankly, it's just a gift to the logging industry and the biomass logging industry
00:43:31.440 in ways that are not consistent with the current science.
00:43:35.440 Yeah, I see that type of just sheer insanity in so many resource extraction projects where
00:43:44.520 the government and the large corporations are completely ignoring science and all of the studies
00:43:53.500 that have been done over all these years. And it's really interesting because I think we need to look
00:44:00.060 at that whether it's Governor Jerry Brown or the National Forest Service, they're looking at the
00:44:07.560 forest as a commodity first and foremost. And if we don't understand that, then we can't really
00:44:13.960 understand what's behind all of these bills that are trying to be passed, such as the forest carbon
00:44:18.260 plan. You know, I was even thinking about the healthy forest initiative that was a political
00:44:25.880 strategy from the Bush administration. You know, the notion that commercial logging is a preventative
00:44:30.860 measure in addressing catastrophic fires, which is something that you've been debunking this whole
00:44:35.120 time. But this policy garnered little attention because it capitalized on the belief that healthy
00:44:40.540 forests are full and green, which again, that's something that you've been debunking too. So
00:44:45.300 the forest carbon plan is nothing new in a sense. It seems like it's just a new spin on a forest
00:44:53.120 mismanagement plan that's been happening for decades. And I guess I'm really interested in
00:44:59.580 just hearing a bit more of the political underpinnings of some of the details of, you know,
00:45:07.020 and I don't want to even ask why, because I know why is money, but how are these things even still
00:45:12.560 being passed when there is so much science? Why is it that the general public either doesn't know
00:45:18.940 about it or potentially just doesn't have the power to shift these types of large forest
00:45:24.520 management plans, especially when it's in their county, their state? I mean, there just seems to
00:45:28.720 be this major misconnection happening here. Yeah, that's a good way to put it. I think in order to
00:45:34.600 understand how to change things. We need to understand how information is being misused
00:45:42.180 and how misinformation is being spread. Back in the 1970s and 1980s, the Forest Service and the
00:45:49.560 logging industry and their political allies, when they were talking about logging on national
00:45:53.960 forests, including clearcutting, they would say, hey, we're doing this because there's money to
00:45:58.220 be made. The Forest Service makes money. It sells public timber to private logging companies and
00:46:03.460 pockets most of the revenue for its budget. The logging industry makes money. The politicians make
00:46:09.100 money. They get campaign contributions off the top, essentially. And they would say, look,
00:46:13.800 we're clear-cutting old growth forests because the best thing you can do is clear-cut that
00:46:18.180 decadent, overmature forest, which is what they called it back then, and plant a thrifty,
00:46:23.020 fast-growing tree plantation. That was their worldview, as you put it. They looked at forests
00:46:28.560 as a commodity. Well, you know, that hasn't changed. The fact that they look at the forest
00:46:33.980 as a commodity, what has changed is the political spin. And that's really important to understand
00:46:38.100 because, you know, by the early 1990s, the spotted owl became a household name and people were
00:46:43.820 starting to wake up to the fact that their national forests were being destroyed for greed and economic
00:46:50.420 motivations. Large areas were being deforested and clear cut and turned into natural wild forest,
00:46:55.960 turned into tree plantations and tree farms. And there was a large public backlash. And people
00:47:01.980 started saying, listen, we don't want our national forests logged. We want them protected.
00:47:06.340 And the Forest Service understood that. The timber industry understood that. The pro-logging
00:47:11.000 politicians understood that. But instead of changing direction, they instead changed the
00:47:16.240 messaging. Instead of saying logging, they say, oh, we're not logging. We're doing fuel reduction.
00:47:21.140 We're doing restoration. We're doing resilience work. We're doing thinning. We're doing hazardous
00:47:26.840 fuels work. There's all these euphemisms, a whole parade of euphemisms that are used
00:47:32.280 to disguise what's really happening. But it's just the same old logging that's always occurred.
00:47:36.940 It's just being presented or spun as a benevolent or benign activity. And we need to kind of see
00:47:43.220 through that smokescreen in order to really change things. And I think, frankly, we also need to
00:47:48.780 confront politicians and land managers and others when they basically play into or disseminate that
00:47:56.820 same kind of misinformation and those same kind of euphemisms. Yeah, I just when you had mentioned
00:48:02.620 the word resilience, I know that back in November 2017, the House passed the Resilient Federal
00:48:08.740 Forest Act, which increases salvage logging on federal properties. And Senator John Barrasio
00:48:15.340 from Wyoming introduced the Wildfire Prevention and Mitigation Act to the Senate, which similarly
00:48:21.280 would exempt logging projects and environmental law and public participation on national forests
00:48:27.480 and prevent federal judges from being able to enforce environmental laws. So this has really
00:48:33.520 been, it's happening, you know, from so many different angles, so many different states,
00:48:39.560 so many different national forests, state forests. It really is an attack on our public lands, an
00:48:45.580 attack on our public forests. And I'm so glad that you're speaking to it in this way and really
00:48:51.180 debunking these myths for us. Because for the listeners out there, when we do hear things like
00:48:56.160 fuel reduction, resilient forest act, we need to look deeper. We need to understand who is behind
00:49:03.320 this, who is making money, what is the purpose, and really look into the scientific research
00:49:08.640 to see is this actually backed by ecologists and it's it's just you know it's like everything else
00:49:16.480 in this time that we cannot take things at face value and it's you know of course it's disturbing
00:49:23.260 to know that the government is spinning these myths to us so that we somehow think and I and
00:49:30.100 just to even hear you say that it's sometimes being sold as restoration I mean it is really
00:49:35.940 really subversive. So I so appreciate you spelling it out for us. I think we absolutely
00:49:44.160 need to understand forest policy from this angle. It gets me all worked up.
00:49:53.520 Yeah, I'm glad you mentioned what we call the Westerman bill that passed the House
00:49:58.140 earlier. It didn't pass the Senate, fortunately. We fought it. A lot of other organizations fought
00:50:04.300 it. And, you know, we had a sign-on letter from hundreds of scientists that fought back against
00:50:09.600 it. But it is really important to understand because this is a piece of legislation that
00:50:14.940 would essentially eliminate environmental laws on national forests nationwide and allow the most
00:50:20.960 intensive, destructive kind of logging, including clear-cutting of post-fire habitat, clear-cutting
00:50:25.820 of old-growth forest, without any environmental analysis and with the most minimal public notice.
00:50:31.880 and it's all packaged under the guise of forest health and restoration and resilience. The word
00:50:37.380 resilience is actually in the title of the legislation. Resilience is a climate change term
00:50:41.760 and the lead author of this bill, a Republican from Arkansas who comes from a logging industry
00:50:48.220 background and many of the others who promote these bills, these are climate change deniers.
00:50:53.980 These are people who proudly proclaim that climate change is a hoax and they're spinning
00:50:59.980 that kind of misinformation. Meanwhile, they're cynically using terms like resilience, climate
00:51:04.960 change terms to promote a rollback of environmental laws and a massive increase in logging in ways
00:51:10.220 that would exacerbate climate change and destroy habitat. So we are pushing back against that. Lots
00:51:16.780 of people are pushing back against it. And lots of people are waking up to these euphemisms and
00:51:22.020 this misinformation and calling their members of Congress and saying, listen, we want our national
00:51:27.960 forest protected. We're not buying this. We want you to focus resources on helping people protect
00:51:33.460 their homes from wildland fire within 100 feet of homes out there on the national forests.
00:51:38.800 Let fire be fire. We don't have too much. It's doing important ecological work.
00:51:43.280 And we should stop logging on our national forests and protect them, much more like national parks.
00:51:47.620 More and more people are saying that and waking up to it. And I think that's a real message of
00:51:52.400 hope. And I think also about all the carbon that's burned through these quote-unquote
00:51:57.680 restorative thinning methods, and the machines, and like you were saying, the damage that the
00:52:03.340 machines cause the forest soil, and all the time it takes for the forest soil to rebuild
00:52:09.840 and create the complexity with the mycelial webs. I really wanted to ask you that question,
00:52:16.680 and I'm so excited to hear your answer. And honestly, this whole conversation has really
00:52:21.420 it's been enlivening it's this topic i'm so invested and engaged in so i've had just really
00:52:29.440 the best time talking to you about this but i would love to ask you one more question before
00:52:34.260 we close and i've read that you've been called a polarizing figure in forest policy which i can
00:52:41.140 see why and you know you've gone as far as suing the forest service to stop salvaging operations
00:52:46.500 So I'd love if you could share with us how the John Muir Project and yourself are working to ensure that these managed lands are allowed to exist in optimal ecological conditions.
00:52:57.900 Yeah, thanks.
00:52:58.520 Well, you know, the John Muir Project is kind of a full service operation.
00:53:01.580 We stand up for science in every way we possibly can.
00:53:05.520 We go out in the field, we gather field data, and we publish original scientific studies, several per year, on these key questions about forest regeneration, about fire history, about wildlife species that depend, many of them, on post-fire habitat.
00:53:20.200 We do public education work and get the message out to the public.
00:53:23.660 We educate policymakers as much as we can.
00:53:26.680 We engage in social media.
00:53:28.320 The other thing we do is we stand up for environmental laws when the Forest Service misrepresents or ignores key scientific studies.
00:53:37.700 One of the things that the National Environmental Policy Act, what we call NEPA, requires basically is that the Forest Service and other land management agencies tell the truth to the public about the impacts and about the science.
00:53:49.720 And if they don't do that, that can be a problem for them.
00:53:52.620 Now, it's difficult in terms of enforcing federal environmental laws on national forests.
00:53:57.840 The courts are required to defer to the agencies, to the Forest Service and other agencies in terms of their interpretation of the regulations of the science.
00:54:07.900 And so it's a very, very, very high hurdle.
00:54:09.960 So there's a lot of illegal logging going on out there that doesn't get stopped because of that deference standard.
00:54:16.100 At some point, that's got to change.
00:54:18.100 But sometimes you can surmount that standard and stop an illegal logging project.
00:54:24.500 And we've done that on a number of occasions through the John Muir Project, working with other partners, including the Center for Biological Diversity, among others, and especially stopping these post-fire logging projects, what the Forest Service calls salvage logging.
00:54:38.700 And really, it comes from what you mentioned earlier, that term salvage.
00:54:42.600 That comes from their view that the only thing that's good about a post-fire area is what you can salvage economically from it in terms of value.
00:54:51.620 And it really just shows and underscores how much they're not seeing it as a forest and how much they're seeing it as a crop.
00:54:58.560 You know, there's a very, very strong consensus in the scientific community that post-fire logging and all the associated activities that go along with it,
00:55:07.420 like the herbicide spraying of toxic herbicides that the Forest Service does after they clear cut this post-fire habitat and the artificial planting of trees,
00:55:16.260 that that's about the worst thing you can possibly do after a fire.
00:55:20.100 And so, you know, we're standing up for the science in every way we can.
00:55:23.660 And, you know, on some of these projects, we wish we could actually challenge more in court, but we do what we can with what we have.
00:55:31.720 And we do stand up for the science and for the environmental laws as often as we can in courts, especially after post-fire logging projects.
00:55:40.240 Well, thank you so much for your work and for the others at the John Muir Project.
00:55:45.020 I so respect the way in which you are working within the systems and outside of the systems
00:55:53.720 and really putting a lot of effort into debunking these myths to the public that our culture is
00:56:00.700 built on and the way that we interact with our forests and our natural ecosystems is built on
00:56:06.880 are these myths, these lies. And to see them for what they are, to understand why they're happening
00:56:15.580 because of the economic value rather than the ecological value, which at the end of the day,
00:56:23.080 ecological value is everything. We can't live on money alone. We really, really need to protect
00:56:31.340 these forests for our own survival, let alone the survival of all the species who directly depend on
00:56:37.840 forests. So I'm so with you. I really appreciate you and your work. And this has been a wonderful
00:56:44.020 conversation. So thank you so much. It's been my pleasure. Anytime.
00:57:01.340 Thank you for listening to For the Wild podcast.
00:57:13.180 I'm Ayanna Young.
00:57:14.760 The music you heard today was by Itasca.
00:57:18.100 The theme music is Silence Returns by Bo and Like a River from Kate Wolf.
00:57:22.500 I'd like to thank our incredible podcast team,
00:57:25.100 our producer and editor Andrew Storrs,
00:57:27.580 our research collaborator and writer francesca glasbell media director molly lebo and music
00:57:34.320 coordinator carter lou mcelroy thanks again and until next week
00:57:38.120 hi this is chad hansen hey chad it's ayana
00:57:57.140 Hey, how you doing?
00:57:58.060 Good.
00:57:58.780 Thank you so much for talking to me so last minute, so late at night.
00:58:02.480 And I thought today, just a couple quick questions about just the current fire.
00:58:08.560 So we talked a lot about forest fires and forest policy and honestly, just the ridiculousness
00:58:14.920 of the rhetoric that's coming out and the myths about forest fires.
00:58:18.280 And I want to get into what Trump is saying right now about the fires in California.
00:58:22.660 But first, I wanted to ask you about what you think about the current fire situation happening in California from L.A. up to Northern California, because when we talked even just, what, two weeks ago now, these fires hadn't broken out.
00:58:36.980 So I'm really interested in hearing your outlook on the cause, what's contributing to these, and, you know, what do you think can be done?
00:58:45.180 Right. Well, we have to have two completely separate conversations about the effect of wildland fire on communities and the effect of wildland fire in wildlands.
00:58:58.000 And they're totally separate things because the fact is, especially in forests and woodlands, we actually still have a pretty significant deficit of fire in our forests.
00:59:08.540 We have less fire now than we had historically. And so we don't want to be putting resources into trying to further suppress fire because, A, that's unnatural, and B, that takes resources away from protecting homes.
00:59:24.480 So we've always had big fires in California.
00:59:27.540 We've had big fires in grasslands and chaparral.
00:59:29.860 We've had big fires in forests or a combination of those things.
00:59:33.460 We actually do have too much fire right now in chaparral ecosystems, basically shrub habitat, lower in elevation, below the forest.
00:59:41.360 And that's overwhelmingly because of so many human ignitions, accidental ignition, some arson adjacent to communities.
00:59:49.260 And so we really need to focus on preventing unplanned human ignitions near communities and letting more lightning strikes burn without trying to suppress those fires in the mountain forests.
01:00:01.940 You know, so ecologically speaking, there's nothing unprecedented about big fires in California.
01:00:07.120 You know, the fires that we're seeing right now are not record fires in terms of their size or intensity.
01:00:12.360 But what is unprecedented is the effect, the impact they're having on homes and on lives.
01:00:19.800 And that is something we can really do something about.
01:00:22.780 So, I mean, there's a few things that go into this.
01:00:24.740 You know, first off, Donald Trump's tweet over the weekend is so incredibly heartless and destructive because, you know, first of all, most of the fires that are burning homes and costing people lives are not in forests in California or elsewhere.
01:00:40.900 Most of the big fires where homes are lost and lives are lost are in grasslands and chaparral.
01:00:46.340 They're in oak woodlands.
01:00:47.820 They're in low elevation areas that are nowhere near a forest.
01:00:50.900 And so this whole idea, this whole focus on logging, on forest management, is really just a diversion to really enrich and benefit Donald Trump's timber industry political allies and the political allies of the GOP.
01:01:05.120 So, you know, I think that's pretty cynical.
01:01:06.680 But the second thing is, and this is something that is really key to understand, is that the areas that are in forests where we have big fires and where homes and lives have been lost, like we saw just days ago in the Camp Fire in Northern California, those are areas where some of the heaviest and most intensive logging has happened anywhere in the state.
01:01:29.420 So in the places that minor portion of fires where it is in forests and lives and homes are lost, these are areas where that's happening not because of the lack of logging, as Donald Trump would like Americans to believe, but because of logging itself.
01:01:43.920 And we published the most comprehensive analysis on this ever a couple of years ago.
01:01:49.040 We looked at millions and millions of acres of fire across three decades of data in the
01:01:53.820 Western United States.
01:01:55.220 And what we found is the forest with the most logging and the fewest environmental protections,
01:02:00.800 those areas actually had the most intense fires.
01:02:03.720 And that's what we saw in the campfire.
01:02:06.040 The fire burned through thousands of acres of area that have been heavily mechanically
01:02:10.400 thinned, so-called, which is actually pretty intensive logging. So that's what mechanical
01:02:15.060 thinning is in most cases, and heavy post-fire logging on both public and private lands. And
01:02:21.460 the fire just swept through that area really intensely and rapidly, and people just didn't
01:02:26.920 have time to evacuate. So this whole notion that the forests are overstocked or overdense,
01:02:33.100 and that's why fires are burning intensely, it's really the opposite. Mature forests don't burn
01:02:38.040 as intensely as forests that have been heavily logged. So, you know, in a sense, we're talking
01:02:42.720 about the relationship between fire suppression and people building their homes on fire-prone
01:02:49.760 landscapes. And so for people who do live near these really degraded forests, heavily logged,
01:02:58.140 like you were saying, is it something where you believe that people shouldn't be rebuilding their
01:03:03.320 homes in these areas? Or do you think that the defensible space is something that even would
01:03:08.780 work in this time when the land has been so degraded? Yeah, it always helps. It always is
01:03:14.120 a very significant factor. The most important thing is the materials with which the home is
01:03:19.840 constructed and basic steps like fire-resistant roofing, ember-proof vents, so those flaming
01:03:26.180 embers that are driven by the winds a mile or half a mile in advance of the flames that they
01:03:30.800 don't get sucked into an attic space or some other exterior vent. Rain gutter guards to prevent
01:03:35.580 dry pine needles and leaves from accumulating next to the roof. You know, simple things like
01:03:39.640 that. I mean, that makes a huge difference, even in extreme fire weather, but we're not going to
01:03:44.300 get to 100% with that. And the fact is that we know now that there are certain areas that because
01:03:50.380 of topography, because of wind patterns are much more dangerous than other areas. You know, we
01:03:55.280 didn't have those data 20, 30 years ago, but we do now. And so I think we need to use that
01:04:00.860 information to inform future building. And there are probably some places where we shouldn't be
01:04:05.040 building at all. And there are other places where if people are going to build there,
01:04:09.780 they need to basically build out of material that is just simply not going to burn, like steel
01:04:13.860 houses, for example. Most steel houses have a very, very high recycled content and it's
01:04:19.640 non-combustible. So I think that there are a lot of things that can be done. The problem is,
01:04:25.280 that people still have this notion that the problem is out there somewhere in distant wild
01:04:31.080 lands. And if there's a fire, some agency is going to step in, state or federal, and they're
01:04:36.520 going to stop the fire. They're going to suppress the fire and save the town. And, you know, that's
01:04:41.060 a dangerous falsehood. The reality is you just cannot stop weather-driven fires, not with giant
01:04:46.720 air tankers that drop giant amounts of water, not with logging, certainly that only typically makes
01:04:52.760 and burn more intensely. But even the places where they just thin really small trees and
01:04:57.260 sometimes it can burn a little bit less intensely in those areas, it still burns right through those
01:05:01.560 areas. It doesn't stop the fire. And so, you know, all of those policies are dangerously misguided
01:05:06.480 and we just have to focus on homes. Yeah. The Trump tweet over the weekend
01:05:11.000 saying that the national forests are mismanaged, they need to be cleaned up. You know, no talk
01:05:16.620 about climate change, no talk about weather-related fires. So there really is this myth and
01:05:23.680 miscommunication that's happening. And I think that's really dangerous for the fate of these
01:05:28.820 areas and for the fate of the future people who will either go back and re-inhabit or inhabit new
01:05:34.440 areas that potentially are dangerous or not being built in the right ways because we're not really
01:05:39.580 talking about the issues. Yeah, that's right. We have to talk about climate change when we're
01:05:44.720 talking about any of these issues. Because the fact is, is that fires are driven and influenced
01:05:50.800 overwhelmingly by weather, and therefore by climate. And climate is influenced by climate
01:05:56.180 change and human activities, both fossil fuel burning and logging. And people forget that
01:06:00.980 logging is the second largest cause of climate change. And forest protection is one of the two
01:06:07.580 key things that has to be done in order to mitigate climate change, in addition to
01:06:11.620 moving beyond fossil fuel consumption. And so Donald Trump's tweet over the weekend is sort of
01:06:17.160 doubly insidious because, number one, it's dangerous for communities because it takes
01:06:22.780 attention and potentially resources away from focusing on creating fire-safe human communities
01:06:29.420 and instead focuses attention on logging operations out in the wildlands. But second,
01:06:34.960 it essentially denies the role of climate change. That's something this administration has been
01:06:41.100 doing from the beginning. And there's a big difference between forest fires and suburban
01:06:48.400 urban fires. I just think about, for instance, breathing in the smoke of trees and duff and
01:06:55.160 plants material versus breathing in horrible toxins from Walmarts burning. And you can imagine
01:07:03.960 all of the stuff on the shelves, all of the wind decks and paint thinners that are burning up in
01:07:08.360 the air all of the insulation the toxic chemicals that are used for building these days and then how
01:07:15.260 that the smoke comes up we're breathing in the smoke it's extremely unhealthy then it also comes
01:07:20.360 down in form of ash on our agricultural lands in our watersheds not to mention that there was talk
01:07:26.800 of a i think chemical company that burned up in southern california so what are your thoughts on
01:07:33.300 the fact that so many of these fires that are burning right now are not forest, but instead
01:07:38.680 these heavily toxic man-made chemicals that are burning up in the air that's filling our
01:07:45.660 lungs and the lungs of our more than human kin.
01:07:49.640 I think that's a really good point.
01:07:51.080 And, you know, it just emphasizes, you know, all the more why we have to focus on structure
01:07:55.580 protection, communities, homes, but also commercial structures within communities and adjacent
01:08:00.940 to communities.
01:08:02.420 And, you know, the reality is, as you pointed out, you know, some of these areas are in
01:08:05.600 forest, but others are in chaparral or grasslands, Southern California, and low elevation areas
01:08:10.240 that are nowhere near forest.
01:08:11.700 And we have commercial buildings burning.
01:08:14.000 We have hardware stores burning with all kinds of chemicals that are being volatilized and
01:08:18.960 going into the air.
01:08:20.060 If we focus on protecting structures, if we ensure fire-safe communities, both residential
01:08:26.100 and commercial, that's not going to happen.
01:08:28.700 We can safely coexist with fire.
01:08:30.440 We really can do this, but we're going to have to move away from these 20th century myths and superstitions that have been driving our fire management policies and encouraging us to look out there over the ridge and think about the problem as being the threat, as being somewhere out there in the wildlands.
01:08:50.180 And it's not. It's right there in the communities. And that's where it has to be addressed.
01:08:54.320 And that's what you were saying earlier in this brief conversation we're having is that in these suburban urban communities, there's some type of human combustion, plus weather related fire issues that are combining to create these fires.
01:09:09.300 That's right. Yeah, there are all kinds of things that are highly combustible in human environments. In fact, if you look at a lot of the imagery that we see coming out of a lot of the fires, you'll see a house that's burned down and it's on fire or it's already smoldered down to ash.
01:09:23.940 and you'll see that the trees and other vegetation next to it that are slightly singed but otherwise
01:09:30.280 green. You'll see homes that are burned down to ash with a green lawn. And that's a circumstance
01:09:35.200 where those homes are burned because they were ignited by embers. In many cases, in fact, most
01:09:41.000 cases, the homes are not burned because they come in direct contact with flames. They burn from
01:09:47.680 embers that are floated by the winds in advance of the flames and land on something combustible,
01:09:52.240 usually a human structure. And the human structures ignite the vegetation around it or
01:09:57.700 singe the vegetation around it. I mean, that's what's actually most combustible in a lot of
01:10:01.800 these areas is the actual human structure. It's not the vegetation in many cases.
01:10:05.700 So basically, one spark in a heavily populated area can create a massive destructive fire
01:10:13.980 because of all of this material that's just ready to combust.
01:10:17.060 Well, it can or it can basically be nothing at all. I mean, a community that's well defended where these principles are applied throughout the community can experience thousands and thousands of embers being driven by the winds from a fire that's nearby through that community and not have homes burn or have very, very few homes burn.
01:10:39.200 Or you can have one home that has a vulnerability because something was missed or because they didn't do their fire safe work or whatever, but the neighbor's homes won't burn because they're properly defended.
01:10:49.780 And that damage is very much minimized and contained.
01:10:52.980 That's the way it can work.
01:10:54.720 And we know it can work that way because we have numerous case examples of real fires, real towns, where these principles were taken very, very seriously before the flames occurred and the vast majority of the homes survived.
01:11:07.040 And we know that.
01:11:07.820 We know it works.
01:11:08.500 we have scientific studies on it, we have case studies, and we know what happens when that's not
01:11:13.720 done. And so I think, you know, again, it really just comes down to this choice that we have to
01:11:18.140 make as a society. Are we going to listen to the voices of fear and cynical opportunism like Donald
01:11:24.420 Trump? Or are we going to pay attention to the science and actually care primarily about people
01:11:29.920 and human lives? Thank you so much, Chad, for having this follow up call with us with such
01:11:35.840 late notice really means a lot to us. And thank you again, Chad. Oh, my pleasure. Thank you.
01:11:41.680 Have a good one. Bye. You too. Bye.
