Western Wildfires Are a Boon for These Native Species
By Tara Lohan
Earlier this month a series of lightning strikes touched off dozens of fires across California, burning 1.5 million acres, choking cities with smoke and claiming at least six lives. Outside California, large wildfires are burning in Colorado and Oregon, too.
For people who live near the path of flames or the drifting smoke, wildfire season can be dangerous. And this year's sudden eruption of multiple blazes is stretching resources thin, as firefighters — already facing restrictions due to the pandemic — work hard to protect lives and property.
Amidst the barrage of media images of charred homes and sweeping flames, it can be easy to forget that for some native species that live in western forests, wildfires are actually beneficial and necessary, creating valuable habitat and some of the most biodiverse forest ecosystems.
Burned forests may seem "gone" or "dead" following a severe fire, but if you look closely "there's an absolute treasure trove of life thriving in there," says wildlife biologist Monica Bond, principal scientist at the Wild Nature Institute.
Longhorn beetles and other wood borers are usually the first to arrive after a fire, when they follow the smell of smoke to feast on recently burned trees, still rich in sapwood but lacking the ability to secrete the sticky, toxic resins that would normally fend off the insects. Black-backed woodpeckers often arrive next, feeding on beetle larvae and carving out nest cavities in the trees that will provide habitat for other birds after the woodpeckers move on.

As flowers and shrubs begin to grow back, that draws more insects and birds. Certain wildflowers, like fire poppies, emerge only from the ashes, and wildfires can create bumper crops of morels, a group of beautiful, delicious mushrooms.
Mammals, meanwhile, arrive in waves, looking for different types of food. "You have seeds that have been exposed by the fire that small mammals are eating," says Bond. That entices larger predators. Studies have also shown that burned forests are beneficial for numerous bat species.
"Then, as long as you don't cut down the standing dead trees, you can have species like spotted owls returning, too," she says. The snags, as the dead trees are called, also provide shelter for a range of forest life, including bluebirds, flying squirrels and Pacific fishers.
Even the fallen dead trees become an important component, cycling their nutrients back into the soil.
It's a process that's been repeated across western forests for millennia, including the Pacific Northwest, Canada's boreal forests, the Rocky Mountains and the Sierra Nevada. All have historically burned with a mix of fire types, including severe wildfires, says Bond.
California's coast redwoods — a big concern this month as fires burned through Big Basin Redwoods State Park in Santa Cruz — are resilient to fire because their thick bark insulates them from the heat.
"Even if fire consumes their crowns — lethal for most conifers — the trunk of a redwood can sprout back to life," Kristen Shive, senior scientist at Save the Redwoods League, wrote earlier this month. "If this happens, they will look really rough for a while and it will take years for their crowns to fill out again, but the tree will have survived."
And in rare cases when the main trunk is too damaged by fire, the tree can still sprout new life from its base.
The wildfires that have burned through the West over the decades have resulted in a patchwork of forest types that create rich biodiversity.
Bond's research found that, one year after the 2013 Rim Fire near Yosemite National Park, the burned area boasted a higher occupancy of spotted owls than even in nearby comparable green forests. One reason: The snags give the owls a good place to perch before they pounce on small prey that also flock to these newly burned areas in search of food.
"Of course, not every single animal loves fire," she adds. "There are some that do well, and then others that don't do as well, but there's plenty of the green unburned forests."
As ecologically valuable as these burned forests are, they are especially important because this type of ecosystem is short-lived.
"The animals that like the fresh burn, they do have to leave at some point as the forest changes — usually it's less than 10 years," she says.

Biodiverse habitat created by burned trees is also at risk of being cut in post-fire "salvage" logging sales by the Forest Service and on private land, which Bond says is "ecologically a terrible idea."
"The Forest Service always proposes it as ecologically necessary to 'restore' the forest," she says. "But if you think about it from the perspective of a black-backed woodpecker, the fire was the restorative process and the burned forest is what it needs."
There's much that can and should be done to limit development in fire-prone areas and help existing communities become more fire safe, she says. But logging trees in forests miles from towns won't make people any safer.
"Wildfire is just a natural part of the dynamics, like the rain or the snow, that happens in the forest," says Bond. "I would love to see the day when we give these severely burned forests the protections that they deserve."

Officials at the highest levels are discussing the possibility of caving in on controlling the coronavirus and instead letting it run rampant throughout the United States until we reach "herd immunity," the point where the virus effectively runs out of people to infect. More than 6,200 scientists, health professionals, and research organizations say this is inhumane and have signed a memorandum rejecting herd immunity as a legitimate strategy.
Herd Immunity’s Unacceptable Toll<p>Resumption of normal life in the United States under a herd immunity approach would result in an enormous death toll by all estimates. Former CDC director Tom Frieden <a href="https://www.washingtonpost.com/opinions/tom-frieden-herd-immunity-wrong-solution-coronavirus/2020/10/16/acb4ae8a-0fe6-11eb-8074-0e943a91bf08_story.html" target="_blank">estimates</a> that another 500,000 people would have to die to achieve 60 percent herd immunity. "And that's the best-case scenario," Frieden wrote in a <em>Washington Post</em> op-ed. "The number of deaths to get there could be twice as high."</p><p>Frieden said that is the best-case scenario because no one really knows if the <a href="https://www.mayoclinic.org/diseases-conditions/coronavirus/in-depth/herd-immunity-and-coronavirus/art-20486808" target="_blank">actual percentage needed</a> to see the virus peter out is to have it <a href="https://thehill.com/opinion/healthcare/521834-covid-19-vaccine-barriers-efficacy-availability-and-acceptability" target="_blank" rel="noopener noreferrer">infect</a> more like <a href="https://www.washingtonpost.com/health/2020/08/31/herd-immunity-covid-19/" target="_blank" rel="noopener noreferrer">65, 70,</a> or even <a href="https://www.vox.com/21451282/herd-immunity-explained-covid-19-pandemic" target="_blank" rel="noopener noreferrer">75 percent</a> of the population. Even if immunity could be miraculously achieved at 50 percent, an estimate <a href="https://www.nature.com/articles/s41577-020-00451-5" target="_blank" rel="noopener noreferrer">published</a> in <em>Nature Reviews Immunology</em> places the range of sacrifice somewhere between 500,000 and 2.1 million deaths.</p><p>That makes it little wonder that Anthony Fauci, the most respected scientist advising the Trump administration on the pandemic, called herd immunity for the coronavirus "total nonsense." Fauci is backed up by the likes of National Institutes of Health Director Francis Collins, who said herd immunity is a "dangerous" and "fringe" component of epidemiology. Ashish Jha, dean of the Brown University School of Health <a href="https://www.bostonglobe.com/2020/10/20/nation/scores-mass-scientists-doctors-sign-open-letter-against-herd-immunity-proposal/?outputType=amp" target="_blank" rel="noopener noreferrer">called</a> herd immunity "junk science."</p><p>The head of the World Health Organization (WHO), Tedros Adhanom Ghebreyesus, <a href="https://www.who.int/dg/speeches/detail/who-director-general-s-opening-remarks-at-the-media-briefing-on-covid-19---12-october-2020" target="_blank" rel="noopener noreferrer">said this month</a> that the only acceptable form of "herd immunity" is achieved through vaccination. "Herd immunity is achieved by protecting people from a virus, not by exposing them to it," the secretary general said. "Never in the history of public health has herd immunity been used as a strategy for responding to an outbreak, let alone a pandemic... Allowing a dangerous virus that we don't fully understand to run free is simply unethical. It's not an option."</p>
Herd Immunity Is the National De Facto Strategy<p>Somehow, none of that has culled herd immunity from being considered as a legitimate approach for fighting COVID-19. Rather, the Great Barrington Declaration has much in common with the Trump administration's approach to the coronavirus, which has led to more people dying from COVID-19 in the United States than in any other nation on Earth.</p><p>A de facto herd immunity approach is the only thing that can explain the push by governors of so many states to <a href="https://blog.ucsusa.org/derrick-jackson/the-push-to-relax-covid-19-protections-exposes-age-old-racial-wounds" target="_blank">reopen</a> bars, restaurants, beaches, bowling alleys, and gyms in states even as the virus has raged and case numbers have been increasing. It is the only thing that can explain the federal designation of meatpackers as essential workers and state demands that teachers go back into classrooms despite outbreaks and deaths related to those professions.</p><p>It also explains how so many of the nation's most respected scientific voices have been silenced. Despite the virus's current "uncontrolled spread" in 34 states and Puerto Rico, according to October 21 <a href="https://www.covidexitstrategy.org/" target="_blank" rel="noopener noreferrer">tracking</a> by CovidExistStrategy.org, the White House has pushed aside Fauci, Coronavirus Task Force Coordinator Deborah Birx, Surgeon General Jerome Adams, and Robert Redfield, the head of the Centers for Disease Prevention and Control.</p><p>In their place, the administration has handed the pandemic podium to <a href="https://www.washingtonpost.com/politics/trumps-den-of-dissent-inside-the-white-house-task-force-as-coronavirus-surges/2020/10/19/7ff8ee6a-0a6e-11eb-859b-f9c27abe638d_story.html?utm_campaign=wp_to_your_health&utm_medium=email&utm_source=newsletter&wpisrc=nl_tyh&wpmk=1&pwapi_token=eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJjb29raWVuYW1lIjoid3BfY3J0aWQiLCJpc3MiOiJDYXJ0YSIsImNvb2tpZXZhbHVlIjoiNWE1ZDQ3N2M5YmJjMGYyNmNiMTViMmI0IiwidGFnIjoiNWY4ZGZhZmQ5ZDJmZGEwZWZiNGViMzQyIiwidXJsIjoiaHR0cHM6Ly93d3cud2FzaGluZ3RvbnBvc3QuY29tL3BvbGl0aWNzL3RydW1wcy1kZW4tb2YtZGlzc2VudC1pbnNpZGUtdGhlLXdoaXRlLWhvdXNlLXRhc2stZm9yY2UtYXMtY29yb25hdmlydXMtc3VyZ2VzLzIwMjAvMTAvMTkvN2ZmOGVlNmEtMGE2ZS0xMWViLTg1OWItZjljMjdhYmU2MzhkX3N0b3J5Lmh0bWw_dXRtX2NhbXBhaWduPXdwX3RvX3lvdXJfaGVhbHRoJnV0bV9tZWRpdW09ZW1haWwmdXRtX3NvdXJjZT1uZXdzbGV0dGVyJndwaXNyYz1ubF90eWgmd3Btaz0xIn0.MyoXrwQD-PwWqdbb70_JfrI_fxHO0be_O_tpTTMXBgE" target="_blank" rel="noopener noreferrer">Scott Atlas</a>, a radiologist and conservative pundit with <a href="https://blog.ucsusa.org/derrick-jackson/public-wants-science-based-policies-for-covid-19" target="_blank" rel="noopener noreferrer">no background</a> in infectious disease science or epidemiology in measuring disease prevalence. Inhumanely ignoring the more than half of U.S. adults having a pre-existing condition that could compromise them for COVID-19, he blithely praises herd immunity, <a href="https://blog.ucsusa.org/derrick-jackson/public-wants-science-based-policies-for-covid-19" target="_blank" rel="noopener noreferrer">saying,</a> "We can allow a lot of people to get infected. Those who are not at risk to die or have a serious hospital-requiring illness, we should be fine with letting them get infected."</p><p>He <a href="https://thehill.com/homenews/administration/521688-birx-confronted-pence-about-atlas" target="_blank" rel="noopener noreferrer">pooh-poohs</a> expanded testing, saying, "you are destroying the workforce." Twitter recently took down one of Atlas's tweets for falsely claiming, "Masks work? NO" and then lying that the WHO says widespread mask use is "not supported." The first sentence of the WHO's <a href="https://www.who.int/emergencies/diseases/novel-coronavirus-2019/advice-for-public/when-and-how-to-use-masks" target="_blank" rel="noopener noreferrer">webpage</a> on masks says, "Masks are a key measure to suppress the spread of COVID-19 and save lives."</p><p>Atlas denies that the White House has a "wide-open strategy of achieving herd immunity." But there's little doubt that the White House is wide open to the idea. Last week, Atlas <a href="https://www.foxnews.com/transcript/trump-adviser-calls-nbc-town-hall-brazen-display-of-media-duplicity" target="_blank" rel="noopener noreferrer">appeared</a> on Fox News <a href="https://www.wsj.com/articles/white-house-touts-document-calling-for-herd-immunity-approach-to-covid-19-crisis-11603051550" target="_blank" rel="noopener noreferrer">to say</a> the thrust of the Great Barrington Declaration "is exactly aligned with the president." That was seconded by a senior administration official who <a href="https://www.washingtonpost.com/health/covid-herd-immunity/2020/10/10/3910251c-0a60-11eb-859b-f9c27abe638d_story.html" target="_blank" rel="noopener noreferrer">told reporters</a> in a conference call that the Great Barrington Declaration "is endorsing what the president's policy has been for months."</p><p>The freezing out of scientists on the Coronavirus Task Force reached deep space levels this week (a metaphoric minus 455 degrees Fahrenheit), with multiple buckets of ice dumped on Fauci. Atlas diminished Fauci as "just one person" on the force, offering only a "limited approach." President Trump called Fauci a "disaster," <a href="https://www.washingtonpost.com/politics/trump-fauci-campaign-biden/2020/10/19/30b2fe58-1226-11eb-82af-864652063d61_story.html" target="_blank" rel="noopener noreferrer">claiming,</a> "People are tired of hearing Fauci and these idiots, all these idiots who got it wrong."</p>
Many Thousands of Lives Can Still Be Saved<p>Atlas's malpractice already merits his dismissal. He should be forced to step down because his disregard for science will surely lead to incalculable disaster if a herd immunity approach becomes official government policy. Calls for his ouster have already begun even from inside the task force. <a href="https://www.washingtonpost.com/politics/trumps-den-of-dissent-inside-the-white-house-task-force-as-coronavirus-surges/2020/10/19/7ff8ee6a-0a6e-11eb-859b-f9c27abe638d_story.html" target="_blank">According</a> to the <em>Washington Post</em>, Birx went to Vice President Mike Pence to suggest removing Atlas. All Pence reportedly did was ask Birx and Atlas to work out their problems on their own.</p><p>There is no time left for such discord within the task force and for discordant messages to come from the White House on how people should protect themselves from COVID-19. The thousands of scientists and public health professionals who signed the John Snow Memorandum say "it is critical to act decisively and urgently," to launch a "robust" response on the level of New Zealand, Vietnam, or Japan—all of which have shown success in containing the virus and keeping the numbers of cases and deaths relatively low.</p><p>The approach that has been proven effective starts with face coverings and social distancing and reducing the temptation we all will feel during the oncoming winter holidays to have extended family gatherings. Researchers from MIT and the Vancouver School of Economics <a href="https://www.medrxiv.org/content/10.1101/2020.05.27.20115139v6.full.pdf" target="_blank">estimate</a> in a working paper that, if the United States had established a national mask mandate in mid-March, between 19,000 and 47,000 lives could have been saved by the end of May. Now that the nation's death toll approaches a quarter million lives lost, and is <a href="https://covid19.healthdata.org/united-states-of-america?view=total-deaths&tab=trend" target="_blank" rel="noopener noreferrer">projected</a> to reach nearly 400,000 by February 1, according to the Institutes for Health Metrics and Evaluation at the University of Washington, the institute estimates we could avoid 74,000 new deaths with universal mask use.</p><p>Importantly, masks protect others, including the most vulnerable among us. This week, the <em>Washington Post</em> reported how coronavirus outbreaks among college students partying in unmasked packs in LaCrosse, Wisconsin was found to have <a href="https://www.washingtonpost.com/health/2020/10/21/la-crosse-wisconsin-covid-outbreak-nursing-home-deaths/?utm_campaign=wp_to_your_health&utm_medium=email&utm_source=newsletter&wpisrc=nl_tyh&wpmk=1&pwapi_token=eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJjb29raWVuYW1lIjoid3BfY3J0aWQiLCJpc3MiOiJDYXJ0YSIsImNvb2tpZXZhbHVlIjoiNWE1ZDQ3N2M5YmJjMGYyNmNiMTViMmI0IiwidGFnIjoiNWY5MWU3YjU5ZDJmZGEwZWZiNTE3OGNmIiwidXJsIjoiaHR0cHM6Ly93d3cud2FzaGluZ3RvbnBvc3QuY29tL2hlYWx0aC8yMDIwLzEwLzIxL2xhLWNyb3NzZS13aXNjb25zaW4tY292aWQtb3V0YnJlYWstbnVyc2luZy1ob21lLWRlYXRocy8_dXRtX2NhbXBhaWduPXdwX3RvX3lvdXJfaGVhbHRoJnV0bV9tZWRpdW09ZW1haWwmdXRtX3NvdXJjZT1uZXdzbGV0dGVyJndwaXNyYz1ubF90eWgmd3Btaz0xIn0.6Ep-AvkJkNqGTE08UsekVlNWR01vYzQe-qg5BPruSQM" target="_blank" rel="noopener noreferrer">led to 19 deaths so far of people over the age of 60</a>.
