The Climate Crossroads: Urgent Warnings, Political Backsliding, and the Power of Truth

Earlier this year, James Hansen and colleagues published a paper titled Global Warming Has Accelerated: Are the United Nations and the Public Well-informed? The authors present extensive evidence leading to a stark conclusion: the climate crisis is more severe than widely reported, and only an urgent global response can meet the challenge. We are already experiencing stronger storms, record-breaking floods, extreme heatwaves, prolonged droughts, and devastating wildfires. These impacts will not only persist but intensify, threatening countless lives and causing enormous economic losses. Perhaps most alarming, the study warns that if current trends continue, the Atlantic Meridional Overturning Circulation (AMOC) – a critical ocean current system – could collapse within 20 to 30 years. Such a tipping point, described as the “Point of No Return,” would drive catastrophic sea-level rise and irreversible shifts in Earth’s climate system.
Now is not the time to deny reality or delay action – yet that is precisely the path the U.S. is taking. The current administration remains the only government preparing to withdraw from the Paris Agreement, while also dismantling international climate partnerships and rolling back energy and climate commitments through executive orders. In August 2025, NPR reported that NASA had been directed to develop plans to terminate at least two satellite missions that track atmospheric carbon dioxide. These satellites also provide crucial data on plant growth, and news of their potential loss has raised alarm among both scientists and farmers.
Confronted by the mounting scientific evidence of a rapidly changing climate, the fossil fuel industry and its political allies have mounted an aggressive global campaign to dismiss climate science as alarmist and portray solutions to reduce greenhouse gas emissions as unrealistic. They promote technological fixes such as carbon capture and emphasize adaptation strategies – rebranded as “resilience” – as sufficient responses to what they frame as an exaggerated problem. To justify inaction, climate science critics even cloak their stance in terms like “climate realism,” while downplaying the escalating risks.
There are three recent YouTube presentations that provide valuable information on this critically important topic. The first is video titled, New Research DEBUNKS Climate Disinformation presented by Dave Borlace from the channel called “Just Have a Think,” which was posted on August 17, 2025. The video focuses largely on a book by Genevieve Guenther called The Language of Climate Politics: Fossil Fuel Propaganda and How to Fight It, with other supporting information. You can also watch a presentation by the author that she gave at The Metcalf Institute in May of this year. The last video is a fact-filled and passionate presentation by Al Gore called, Why Climate Action Is Unstoppable – and “Climate Realism” Is a Myth. Together, these provide a solid update about where we are regarding the climate crisis.
Announcing the North American Forest Initiative

Dr. Dominick DellaSala, a long-time CBI Associate, has dedicated over four decades to nonprofit conservation work as a global biodiversity and climate scientist. He has also served as President of the North America Section of the Society for Conservation Biology. An internationally recognized author, he has published more than 300 peer-reviewed articles and co-authored nine award-winning books, including Temperate and Boreal Rainforests of the World: Ecology and Conservation, Mixed-Severity Fire: Nature’s Phoenix, and Conservation Science & Advocacy for a Planet in Peril: Speaking Truth to Power. Dr. DellaSala will soon be launching a new CBI initiative focused on North American forest conservation. Content is currently being added to the CBI website describing the important work Dr. DellaSala and his colleagues are doing and is expected to launch publicly around mid-month. This important initiative will be a valuable resource for all who care about the long-term protection of forests. Please check in here over the coming weeks.
National Grassland Quality Modeling

Over the past two years, CBI spatial modelers have been developing map-based products to support the USDA Conservation Reserve Program (CRP). A central goal of this work is to generate more accurate maps of grassland quality, enabling large-scale evaluation of ecosystem services. This spatially explicit approach provides USDA with the information needed to track the relative conservation success of a program that voluntarily safeguards over 26 million acres of private farmland nationwide.
To achieve this, CBI integrated cutting-edge remote sensing data with key environmental indicators and applied machine learning techniques within the Google Earth Engine platform. Draft models have already been produced at a national scale, with advanced methods tested in several grassland-rich states. Each model incorporates three primary components: vigor, composition, and landscape structure and resilience. Preliminary results (Figure 1) have also been built into an online assessment tool, which is currently under review.

Dr. Alexandra Syphard Featured on NPR – Insights on Roads, Wildfires, and Unintended Consequences

We’re delighted to share that Dr. Alexandra Syphard, Senior Research Scientist at CBI and Director of Science at the Global Wildfire Collective, appeared on NPR on August 28, 2025, to discuss proposed changes to the Roadless Rule and their potential implications for wildfire risk.
Dr. Syphard eloquently invoked the Sevareid Principle, reminding listeners that “the law of unintended consequences is a very real law.” She emphasized that while roads may facilitate access for fire suppression, they also tend to increase fire ignitions—as data shows up to four times more ignitions within 50 meters of roads than in roadless areas. Moreover, road construction transforms vegetation—favoring flammable grasses in place of mature forest—and thereby amplifying fire risk.
Marine Mammal Protection Act Under Threat
With overwhelming public support, the Marine Mammal Protection Act (MMPA) was signed into law by Richard Nixon on October 21, 1972. This landmark legislation marked a turning point in marine conservation, establishing comprehensive protections for whales, dolphins, manatees, sea otters, seals, sea lions, walruses, and polar bears within U.S. waters.
The MMPA was groundbreaking in its adoption of an ecosystem-based approach to wildlife conservation, making it the first law of its kind in the world with its central aim to maintain sustainable populations of marine mammals in relation to the health and capacity of their habitats. The Act not only brought an end to commercial whaling in the U.S., but also laid the foundation for the recovery of numerous species once teetering on the brink of collapse.
Thanks to the MMPA, no marine mammal species have gone extinct in U.S. waters since the law was enacted. In fact, many populations have made remarkable recoveries, including humpback whales, gray whales, gray seals, and California sea lions. When the MMPA was passed, humpback whale numbers had plummeted by 95%, with only a few thousand remaining. Today, their populations have grown significantly – approximately 13,000 in the North Atlantic and around 21,000 in the North Pacific.
Despite this amazing recovery, like most marine mammals, humpback whales still face serious threats. Climate change is perhaps the most significant medium-term threat as rising ocean temperatures disrupt their food sources. But there are other day-to-day impacts that are causing problems such as entanglement in fishing gear, vessel strikes, vessel harassment, and underwater noise take their toll.
Today, however, this critical legislation faces serious threats as a draft MMPA reauthorization bill was introduced by Rep. Nicholas Begich (R-AK) in early July. The proposed Act reauthorization would –
- Downgrade the statute’s mandate from healthy populations to mere survival
- Weaken the legal standards for authorizing activities that kill and injure marine mammals
- Eliminate protections from commercial fishing
- Hamstring the ability to issue any new regulations under the Act
- Drastically undermine marine mammal conservation
- Delay action (10 years) to save the critically endangered North Atlantic Right Whale
The MMPA has been a major success and is essential to safeguarding the future of marine mammals and the ecosystems they call home.
Bats in Eastern Washington

Bats are experiencing severe declines, with 90% of species affected and 53% at risk of extinction within 15 years, making them one of the most threatened vertebrate groups in North America. Bats are extremely important ecologically as they provide major ecological benefits including insect control, pollination, and seed dispersal. Over the last two growing seasons, CBI scientist Dr. Chris Cosma has been monitoring bats and nocturnal flying insects in Douglas County, Washington in order to better understand how different landscape conditions impact bat species richness and abundance. Funded by the Washington Department of Fish and Wildlife, Chris used the latest acoustic monitoring technology to survey bats and camera traps to evaluate their prey base – primarily moths.
He surveyed sites that represented a gradient of surrounding land types—active cropland, cropland under restoration via the Conservation Reserve Program (CRP), and regional protected areas. Using generalized linear mixed-effects models, he analyzed how bat activity, species richness, diversity, and feeding behavior was influenced by environmental variables including climate, land cover, water features, and nocturnal flying insect abundance.

KEY FINDINGS
All 14 bat species native to the region, including at-risk species like Townsend’s big-eared bat, were detected during the study. Temperature was identified as the strongest environmental factor influencing bat activity, with both nightly fluctuations and long-term minimum temperatures significantly predicting bat diversity, activity levels, and foraging intensity. While nocturnal insect abundance had a smaller effect, it still showed a significant influence on bat feeding behavior, particularly at finer temporal scales.
Agricultural practices had mixed effects on bat communities. Areas with insect-pollinated crops and greater crop diversity within a 2–5 km radius played a key role in supporting vulnerable and rare species like Towsend’s big-eared bat. The USDA Conservation Reserve Program-enrolled lands, however, showed consistent negative associations with bat activity, diversity, and foraging. These lands are currently in early stages of restoration.
Management implications
These findings show that diverse bat communities play a key role in eastern Washington’s agricultural landscapes. Bats were more active in areas with diverse insect-pollinated crops, suggesting that diversified farming provides better foraging habitat than simplified, wind-pollinated systems. Protecting and expanding areas with water sources is also essential for bat conservation.
New Landscape Intactness Assessment for California
In 2016, the California Energy Commission funded CBI to conduct an advanced landscape condition analysis, intended to use as a foundation for evaluating ecosystems, species habitats, and areas designated for renewable energy development. The resulting product was integrated into several statewide planning efforts, including the California Department of Forestry and Fire Protection’s Fire and Resource Assessment Program (FRAP 2017 Assessment) and the California Department of Fish and Wildlife’s State Wildlife Action Plan (SWAP 2025 Update).
CBI’s modeling approach synthesizes complex spatial data into a suite of metrics that quantify terrestrial intactness—an estimate of naturalness or the degree of human disturbance—through a multidimensional lens. The resulting interactive product allows for identification of natural areas that maintain higher levels of ecosystem integrity, thus maximizing support of wildlife and ecosystem services. It also highlights key factors influencing the State’s landscape condition, such as infrastructure and urban development, and supports a deeper understanding of the wide range of human impacts occurring along that continuum.
In 2024, the California Department of Forestry and Fire Protection (CAL FIRE) funded an update to produce a new version of this terrestrial intactness product, incorporating significant improvements in data quality and the inclusion of some new inputs such as invasive vegetation and habitat fragmentation metrics. The analysis provides a present-day estimate of the degree to which California’s natural landscapes have been impacted by human disturbance and the drivers at play in any given location.
The 2025 version has been crafted with an eye towards incorporating data derived from more advanced methods, likely to be updated at regular intervals, thus setting the stage for products more directly comparable across time. The current upgrades and advancements in the analytical model provide a solid foundation for future work – such as finer resolution models that would offer additional detail needed to address certain planning and management issues by agencies, NGOs, and others

Landmark Conservation Policy Rescinded

Last week, USDA Secretary Rollins announced that the Administration is rescinding the landmark 2001 Roadless Rule Policy, which prohibits road building and resource extraction on 58.5 million acres (~30%) of National Forest lands. The rule was enacted after a public comment period and 600 open meetings around the country resulting in 1.5 million comments – overwhelmingly in favor of the rule – from citizens demanding that the degradation of environmentally sensitive roadless areas be halted.
What is a Roadless Area?
Roadless areas are National Forest lands that have remained unroaded for a variety of reasons, including inaccessibility and environmental sensitivity. Roadless areas provide many ecosystem services that are not as readily available in roaded landscapes, such as:
• Provide refuges for many threatened, endangered, and endemic fish and wildlife species.
• Contain old-growth forests and other rare habitat types that are more resistant to forest fires and effective at controlling climate change.
• Provide clean drinking water to millions of Americans.
• Serve as unspoiled reference areas for research into issues such as climate change.
• Act as buffer zones against invasive, noxious, or exotic species.
• Protect important historic and cultural areas.
• Host a wide variety of outdoor recreation activities for visitors.
Leading up to the enactment of the Roadless Rule, several scientific studies demonstrated unequivocal support for the protection of roadless areas (see insert). At the same time, scientists were turning their attention to documenting the impacts of roads and associated logging on the extent and rate of forest fragmentation across the nation (see Conservation Biology 2000 – Special Edition on roads).
Roads are one of the most destructive human impacts on the planet and the U.S. has more roads than any other nation on Earth. The current road network present in our National Forests is already over 378,000 miles, enough to drive around the globe nearly 16 times. Consequently, roadless areas are what remain of the nation’s dwindling intact and functional ecosystems.
Unfortunately, once roads are built, they rarely go away. The negative impacts of roads on the environment and natural ecosystems are numerous and significant. The physical presence of roads is problematic in many ways – wildlife is particularly impacted – but the bigger issue is the sprawling impacts that follow. Widespread habitat destruction, fragmentation, and degradation are made possible by the access roads provide.
In her recent statement, Secretary Rollins stated, “This move opens a new era of consistency and sustainability for our nation’s forests. It is abundantly clear that properly managing our forests preserves them from devastating fires and allows future generations of Americans to enjoy and reap the benefits of this great land.”
Contrary to the claim that it is ‘abundantly clear’ this action will make things better; the scientific evidence clearly states the opposite. With regard to wildfire, numerous researchers have clearly demonstrated that roads significantly increase human-caused ignition. And once a fire is started, the corridors of invasive flashy fuels that roads promote only increases the risk of a severe fire.
The benefit to future generations is truly aspirational, but destroying and degrading our public lands for corporate profit is simply stealing from current and future generations. Our National Forests (including roadless areas) already provide billions to the local economies. This economy is sustainable long-term as it does not rely on extraction.
The majority of the American people love that we still have unspoiled public lands that belong to all of us. The vision the Roadless Rule embodied was popular in 2001 and it is even more popular now. Rescinding the Roadless Rule is indefensible on all counts.
Designing Sustainable Recreational Trails

Recreation on public lands has boomed over recent years and trails are a major value to many outdoor enthusiasts. However, there are many aspects of trails that influence their long-term sustainability. Trails are not benign ecologically and there are numerous considerations for reducing their impact on natural ecosystems. There are also economic, physical, and social considerations (including Tribal treaty rights) to consider when designing a sustainable trails network.
On July 26, CBI’s Geospatial Team Lead, Rebecca Degagne, was a guest of the American Trails “Advancing Trails Webinar Series” giving a talk on Data-Driven Decision Support for Sustainable Trail Planning and Management. Rebecca gave an overview of the ongoing work that CBI has been involved in to provide the US Forest Service Region 6 (Oregon and Washington) and Deschutes Trails Coalition (Oregon) a decision support application that provides an assessment of the environmental, economic, physical and social sustainability of existing and potential trails. Incorporating 150 datasets, the tool assembles data such as aesthetic value, maintenance costs, potential user type conflicts, landslide vulnerability, habitat vulnerability to produce a score for each trail segment in question. The pilot Trails Assessment and Planning Tool has been well received and getting lots of use.

Global Wildfire Collective Expert Group Meeting
A reflection by our Executive Director, Robin Jones


Our second day was a field visit to the Parque Nacional Natural Chingaza, on the outskirts of Bogotá. There, we were given permission to visit the site of a sizable January 2025 fire in the páramo. Páramo is a rare and unique high-altitude ecosystem found in the Andes, particularly in Colombia, and is known for its high biodiversity and its crucial role in water regulation and storage. Despite fire being historically documented in this ecosystem, little is known about the frequency and trends of fire in these high-elevation landscapes. Researchers from the Parque Nacional, Universidad del Rosario and Instituto Humboldt presented their latest research aimed at better understanding the nature fire regimes of the ecosystem, how those regimes may be changing due to climate change and human influence, and how resilient the ecosystem is to fire. The day reiterated a need for scientific understanding of fire regimes and fire ecology in lesser-populated, lower fire frequency ecosystems of the Global South.


We left Bogotá feeling inspired, motivated and empowered by our new partnerships and relationships to accelerate the pace of understanding and adaptation to fire via the work of the Global Wildfire Collective. We look forward to sharing more updates as we kick off new work in the region.

WELCOMING KIM DELFINO TO OUR BOARD OF DIRECTORS
An Important Message
From Robin Jones, CBI Executive Director
We are all in this together!
During these politically challenging times, we have put much thought into how to carry on with our work to protect the values we hold dear. In some ways, we are in a relative position of privilege, in that the work we do every day continues to help safeguard our planet. Below are three ways you can participate in our mission.
CBI Associates Program
BECOME A CBI ASSOCIATE
The CBI Associates program aims to partner with researchers and scientists working in the conservation science fields to expand our impact. The program has been designed to enable researchers and scientists that are not in CBI’s employ to leverage the CBI brand and institutional infrastructure to obtain and manage grant-funded projects within an established and reputable non-profit organization.
This program may be of particular interest to Federal employees that have recently lost jobs in these fields, particularly if they have ongoing research or planning projects funded with soft money, or a track record of successful proposal development. If you, or someone you know, were impacted by the recent Federal government cuts, you can learn more about the CBI Associates program here.
Help Preserve Environmental Data

BECOME A DATA BASIN VOLUNTEER
According to a New York Times analysis published on February 2, 2025, “more than 8,000 web pages across more than a dozen U.S. government websites have been taken down … as federal agencies rush to heed President Trump’s orders.” Already, missing data related to “climate” and “resilience” have been reported. CBI’s Data Basin platform is well suited to host this type of spatially explicit data and it is free to use. If you have a background in GIS and willing to volunteer your time toward collecting and uploading data to Data Basin to help preserve important natural resource data, please contact us at info@consbio.org and we will be in touch about ways you can contribute.
Make a Donation
Of course, financial support is always welcome, even more so in a time when organizations like CBI face uncertainty about the availability of government funding. Any contribution you are able to make is much appreciated and will help ensure that CBI continues to do its important work under these particularly difficult circumstances.
Where Have All the Porkies Gone, and Can We Get Them Back?
Porcupines have been disappearing from western forests for years, and CBI is exploring if we can get them back in the Southern Sierra Nevada to also help the Pacific fisher.
Concerns have been mounting in recent decades over an apparent decline in the distribution and abundance of the North American porcupine (Erethizon dorsatum) throughout the western US. This decline is especially evident, and troubling, in the southern Sierra Nevada of California, where CBI has been leading the effort to recover the endangered distinct population of fishers (Pekania pennanti). Porcupines were once a favorite, if not the favorite, food of fishers, but they are completely missing from the fisher diet in recent decades. In addition, porcupines are “ecosystem engineers” whose gnawing on tree bark creates multi-forked treetops, platforms, and cavities used by fishers and numerous other wildlife species, from nesting raptors to flying squirrels to martens.
CBI is currently exploring with partners options for returning porcupines to southern Sierra Nevada forests to benefit the ecosystem and to help recover endangered fishers. Once common in Sierran mixed conifer forests, “quill pigs” were routinely shot and poisoned as pests during much of the Twentieth Century, because their food habits damaged trees and reduced their timber value. This persecution has largely ceased, but population declines have continued to the point that they seem to be completely absent from fisher habitat.
Returning porcupines to the southern Sierra Nevada will not be easy. Reasons for their disappearance are complex and not fully understood; their reproductive rates are extremely low (a mother can birth only one porcupette per year); and there is an inherent conundrum in that fisher predation on porcupines could hinder efforts to re-establish a population. Nevertheless, we believe the effort is worth a try. The first step is establishing a working group of porcupine and forest ecology experts to review all aspects of the problem and to develop a reintroduction feasibility study. We are in the very early stages of contacting interested experts and will be pursuing funding opportunities for a feasibility study.
The Global Wildfire Collective

A NEW CONSERVATION BIOLOGY INSTITUTE INITIATIVE
Altered fire regimes are leading to profound ecological transformations, posing serious threats to biodiversity and driving large-scale species extinctions. Wildfires are also disrupting essential ecological services proportionately that humans depend upon (e.g. clean air and water, soil stability and fertility, carbon storage). As the wildfire crisis accelerates, there is an urgent need for trans-disciplinary, trans-sector, and globally coordinated research to understand the causes and consequences of changing wildfire patterns, and how these scale across space and time. Yet, wildfire has traditionally been studied in institutional and disciplinary silos without accounting for the critical interconnections among human and ecological systems, and all the components within.
To break down these silos and promote cross-discipline, global collaboration, CBI has launched the Global Wildfire Collective (GWC). The GWC is an interdisciplinary research and capacity-building group whose work cuts across topics, sectors and actors that drive and are subject to the impacts of wildfire. The GWC is committed to establishing and proliferating wildfire resilience and recovery strategies that produce multiple co-benefits to maximize well-being in ecological and social systems.

Wildfire in the Built Environment

Just days ago, some of the most destructive wildfires in California history have been contained in the Los Angeles area. Given the magnitude of impact, it should be no surprise that in these early days of the post-fire investigations, there has been a multitude of misinformation, confusion, and finger-pointing circulating in the media. Over the past month, many media outlets have turned to CBI Senior Research Ecologist, Dr. Alexandra Syphard, to provide their audiences with her world renowned research-based perspective on these devastating fires. We have summarized some of her salient insights for you in this month’s newsletter.
While climate change is most certainly a contributing factor to the current fires in Southern California, the circumstances that led to these fires are more complex than any single factor. Pre-existing seasonal weather patterns of drought and wind combined with population changes, land usage, vegetation, the built environment, and recreation patterns all contribute to the vulnerability of the region to large-scale, destructive fires.
When many of us hear the word “wildfire”, we think of forest fires. However, the majority of Southern California is not a forested ecosystem, and most structures lost to California wildfires are in non-forested ecosystems. California is dominated by chaparral (shrubland) ecosystems, and in Southern California, much of the chaparral landscape has been aggressively invaded by non-native grass species. Chaparral ecosystems have adapted to a fire regime of high intensity fires that occur at low frequency intervals, historically seeing at least 30 years between burns. However, grasslands naturally experience far more frequent fire cycles, often only 1-5 years between fires.
A key component in understanding the fires in Southern California is understanding the dynamic between the native and non-native species in these areas. When they do burn, evergreen shrublands burn at high intensities, and grasses are extraordinarily flammable. When grasses ignite, they act as kindling to the chaparral, which can generate the ember load that carries firebrands kilometers ahead of a fire front (even over 10-lane freeways) during extreme wind conditions. Chaparral will recover well after infrequent, high-intensity wildfires. However, non-native grasses colonize those areas quickly. If chaparral cannot recover to overtop them, the grasses persist, adding more high-flammability material to the ecosystem.
Many chaparral species will struggle to recover when the interval between fires shortens, because the dormant, fire-cued seed bank can take up to 20 years to replenish. If fires recur before then, there will be insufficient seed stock, ultimately preventing regeneration and paving the way for even more non-native grasses to invade.
Southern California experienced a host of climatic conditions leading to the fires that erupted on January 7th, but none of these conditions are unprecedented and most are common to the region.
First, there are the high speeds of the Santa Ana winds, spreading embers for up to 2 miles, which expedited the growth of the fires, making them extremely challenging to fight. Santa Ana winds are a known aspect of the Southern California climate, with winds picking up regularly every Fall and Winter in the region (gusts commonly reaching 60 mph).
Second, we have heard so much about the drought in the area, yet Southern California’s climate regularly experiences about 6 months of dry weather each year. The La Niña-driven drought in 2024/25 leading up to these fire events was preceded by a very wet El Niño winter weather pattern in 2023/24, meaning there was a large amount of herbaceous vegetation growth that then became very dry during the drought, creating a bulk of abundant flashy fuels, ripe for fire. Again, the El Niño/La Niña hydrologic cycles are to be expected, with an average cycle of 2-7 years between each.
Finally, because lightning storms are very rare in the region, we know that virtually 100% of fires in Southern California are human-caused ignitions, whether that is from a faulty power line, a dropped cigarette butt or sparks from machinery. The more humans, the more potential for ignition- and California’s population has almost doubled in the past 50 years. In other words, while we would like to think that Southern California has experienced a relatively rare “perfect storm” of conditions leading to these devastating fires, in actuality, these conditions co-occur at a reasonably frequent interval. The element of these fires that is relatively rare is the fact that the ignition occurred close to a large metropolitan region, while the region was experiencing severe wind conditions.
Still, it is shocking for most of us to see this scale of fire in a large urban area. We tend to feel safe from wildfires in the city, and in most cases, we are. However, every urban region has edges in which the built environment abuts undeveloped or “wild” land. These wildland-urban interface (WUI) areas represent about one-third of all US housing stock, or about 44 million households.
So, what does science tell us we can do to increase wildfire resiliency for the ⅓ of Southern California households that are in the wildland urban interface?
Defensible Space On and Near Your Property

- The space within 5 feet of your home should be regularly maintained, kept clear of dry vegetation and debris, and ideally hardscaped with fire-resistant materials such as gravel, concrete, brick, etc…
- The zone between 5 and 30 feet of your home should be “lean, clean and green”– regularly maintained, pruned and irrigated during periods of drought to ensure the vegetation does not become dried out.
- Between 30 and 100 feet of your home, focus on removal of dead plant material and maintain spacing between plantings. This zone is the safest location for siting your outbuildings and fuel tanks.
- If your home is on a steep slope, prioritize downslope vegetation management
- If you are in a dense neighborhood in which homes are close together, pay special attention to vegetation management between homes, to limit the risk of fire spreading from home to home.
- Do not leave wood or brush piles near your home
- Consider landscaping your property with native plants, as they tend to be less flammable than many non-native landscaping plants, especially grasses.
- Work with members of your community to help neighbors that may not have the means or ability to create their own defensible space. The more your entire neighborhood is defensible, the safer your home will be.
Home Hardening

- It is ideal to use Class A roofing materials (clay, cement or fiberglass-based) instead of wood shake or shingled roofs.
- Keep your roof and gutters clean of plant debris that can dry out in periods of drought.
- If you have open-eaves on your home, consider retrofitting to create soffited eaves with vents.
- Cover all your attic and basement/crawl space vents with ⅛ inch non-combustible metal mesh screens to prevent embers from entering your home.
- Choose multi-paned windows with tempered glass when you upgrade your windows to limit the risk of glass breakage caused by radiant heat.
- Consider replacing decking with non-combustible materials such as plastic composite decking or fire-retardant-treated wood deck boards.
- Cover your chimney outlet with ⅜ inch screening to prevent embers from leaving your chimney, and keep your flue closed during fire season to prevent embers from entering the home via your chimney.

- A major component of creating fire-safe neighborhoods has to do with the zoning of the area. Neighborhood “islands” that are not contiguous with existing developed areas are at higher risk due to more wildland-urban interface exposure. Infill developments tend to be significantly safer. Similarly, neighborhoods that are planned with less flammable landscaping or features between them and the wildland tend to be safer from fire. Features such as golf courses, tennis courts, solar arrays (with well-maintained vegetation) can add to the defensible space for an entire neighborhood. Zoning at the neighborhood/city level (infill, greenspaces like golf courses between wildland and developments).
For more detailed information on how you can better protect your home, we recommend you refer to the Sustainable Defensible Space website.

What We Accomplished in 2024
Conservation Biology Institute had an exceptionally productive 2024, with a broad array of projects carried out with partners old and new. As we move forward into the new year, we have paused to reflect upon our successes of the previous year and summarize some of the highlights for you below.
DATA BASIN

Data Basin continues to grow. Early in 2024, Data Basin reached another milestone of 50,000 registered members. The current number of members approaching 56,000 with the number of interactions with the platform is averaging 30,000 per month. Majority of the users are from the US, but users from almost every country in the world continue to visit the system routinely. Also, the content available in the platform continually grows and now provides access to over 35,000 individual datasets. Most importantly, members are successfully using Data Basin to address a wide range of topics, including conservation planning, renewable energy, climate resilience, sustainability, and species recovery.
CONSERVATION IN AGRICULTURE
Supporting USDA Conservation Reserve Program Lands

The Conservation Reserve Program (CRP) is a federally funded land conservation program administered by the USDA Farm Service Agency and currently manages over 25 million acres of private farmland in the US and is looking to expand. Through the integration of science, spatial modeling, and software development, CBI continues to provide support to significantly improve conservation outcomes and efficiency of program management.
California Healthy Soils Initiative and Alternative Manure Management Program Support
Working closely with the California Department of Food and Agriculture, CBI updated and made enhancements to two existing online tools that help process grant applications for farmer support programs aimed at reducing greenhouse gas emissions- one through enhancements to sequester more carbon through the promotion of soil health and the other through the improved management of farm animal manure.
OUTDOOR RECREATION
Recreation Conflicts with Tribal Rights

Outdoor recreation is an important component of conservation for many reasons; however, many locations are becoming overwhelmed by the numbers of users engaging in a growing list of activities. Furthermore, in some regions such as Washington state, Tribal people’s rights to the land and resources provided by long-standing treaty are becoming increasingly compromised by outdoor recreation activities. CBI has been engaged to work with Tribes and state agencies to find practical solutions to the growing number and intensity of recreation conflicts on finite natural resources.
Assessment Planning Tool for Oregon and Washington Trails
Based on a previous prototype for Deschutes County, Oregon, which resulted in the creation of a web-based decision support tool to improve the management of multi-use trails in the county, CBI has begun to expand this work to incorporate all trails in Oregon and Washington on U.S. Forest Service lands. Work will continue in 2025 with the goal to provide a user-friendly online dashboard, which will allow trail managers to plan and manage for trail sustainability throughout much of the Pacific Northwest.
RENEWABLE ENERGY & SUSTAINABILITY
Supporting Sustainable Offshore Wind Development in California
Marine offshore wind energy development presents an opportunity to help California achieve its 100% renewable energy goals. CBI continues to provide data and collaborative platform support using the California Offshore Wind Energy Modeling Platform for the ongoing planning activity.
CEQA Site Check Tool
Site Check is an online tool built to accelerate the production of housing (especially low-income housing) by identifying where existing streamlining options under the California Environmental Quality Act (CEQA) may apply. Site Check allows users to filter parcels based on specific CEQA provisions. The tool is actively being used to accelerate housing development in California while avoiding areas that are environmentally sensitive such as wetlands, rare natural habitats, locations of rare native species, key landscape connectivity corridors, and hazard zones.
Climate Smart Forest Restoration Tools
Seedlot Selection Tool
The Seedlot Selection Tool is a GIS mapping program designed to help forest managers match seedlots with planting sites based on changing climates. The tool, which covers the North American continent, is being actively used to more closely match seedlots with future growing conditions.
USFS Climate Analog Tool
The US Forest Service asked CBI to build upon the aforementioned Seedlot Selection Tool to help increase positive outcomes of their conservation and restoration efforts. The Climate Analog decision support tool will provide forest managers with access to climate-smart generalized seed transfer and vegetative information using 19 different climate variables to accommodate a spectrum of adaptive genetic variation among species to better inform restoration decisions.
WILDFIRE
Global Wildfire Collective

CBI has embarked on the development and launch of the Global Wildfire Collective, an online platform and community being established to facilitate easy access to and sharing of research, publications, data, models and tools among wildfire researchers and operational practitioners. The platform will support discussion, collaboration and knowledge-sharing across wildfire-related disciplines, ecosystems, and regions. When established, this will be the only global resource of its kind.
Centro de Conservación Biológica de Operaciones Forestales (CCBOF)
In partnership with the Academia Nacional de Bomberos de Colombia, CBI is embarking on the development of the Centro de Conservación Biológica de Operaciones Forestales (CCBOF), a wildfire research, collaboration and education center to increase regional capacity and expertise across the Americas. CCBOF will be built upon the Global Wildfire Collective to accelerate advancements in wildfire science and ecology in order to provide practical guidance for policy makers, insurers, community members, fire departments and land owners/managers. The Academia Nacional de Bomberos de Colombia serves as one of very few Latin America and Caribbean-regional centers for firefighter and community education, having trained firefighters from virtually every country across the LAC-region.
California Wildfire Projects
Sierra Nevada Forest Resilience Decision-Support
CBI completed a series of modeling exercises to assess and predict wildfire impacts in the Sierra Nevada in California. Unlike previous efforts that focused exclusively on the fuel component of the fire risk modeling, our work introduced the concept of fire-atmospheric coupling which integrates the all-important air component to fuels. Results demonstrate the importance of strategic forest thinning as thinning in some locations can actually make the risk of severe fire worse.
Giant Sequoia Lands Coalition Data Gateway
CBI partnered with Plumas Corporation to develop a new Data Basin Gateway, as a collaborative working space dedicated to sharing and discussing data relevant to the protection of Giant Sequoia groves in the Sierra Nevada that are threatened by climate change. The gateway is currently under review and expected to be publicly launched in 2025.
CALFIRE Impacts Study
Using a vegetation succession model, this project explores how climate change, management actions, and projected residential growth in the wildland urban interface may influence wildfire activity and downstream effects on vegetation type conversion, carbon release, and biodiversity in Southern California forests and shrublands. The resulting maps and spatial products will help managers prioritize locations for conservation action to protect co-benefits to humans and natural resources.

Tuolumne Wildfire Defense Planning
CBI partnered with EN2 Resources, Inc. and the Tuolumne Utilities District (TUD) to develop the TUD Wildfire Defense Plan, a roadmap for addressing wildfire risk to the county’s water system and water treatment facilities. The wildfire risk mitigation plan is meant to guide projects that aim to achieve fuels reduction, habitat enhancement, and recreation benefits in the region, while building resilience for the utility district infrastructure.
Resilience Planning for Southern California Montane Forests
CBI is partnering with the U.S. Forest Service and San Diego State University to apply the latest research on interactions between multiple disturbances specific to this ecoregion to plan more effective conservation action. The goal is to further develop an actionable strategy to address the many threat (especially wildfire) to these unique forest ecosystems.
SPECIES ASSESSMENT & PLANNING
Southern Sierra Nevada Fisher Conservation Assessment and Strategy 2.0

CBI has been engaged in assessing and planning for the conservation and recovery of Pacific fisher (Pekania pennanti) for many years in the Southern Sierra Nevada. The latest iteration of the work includes a major update on the conservation strategy for the species prompted by large landscape disturbances such as catastrophic wildfires over recent years that have negatively impacted the population resulting in the species being listed as endangered by the U.S. Fish and Wildlife Service.
Stephen’s Kangaroo Rat Monitoring

In year four of a close partnership with Riverside County Habitat Conservation Agency, Bureau of Land Management, U.S. Fish and Wildlife Service, and other researchers, CBI continued to lead the multi-year range-wide monitoring and management plan development for the endangered Stephens’ kangaroo rat (Dipodomys stephensi), a tiny rodent native to Southern California’s shrinking grasslands.
WDFW Bat and Moth Monitoring

A number of bat species such as Townsend’s big-eared bat (Corynorhinus townsendii) are in decline throughout Washington. This ongoing project uses acoustic monitoring and species identification software to assess the status bats across different landscapes to better understand what conditions correlate with high levels of bat occurrences and abundances. The project is also using sophisticated camera traps and new AI-driven technology to monitor moth populations, which make up the major prey base for many of the bat species.
Washington Wildlife Connectivity Mapping
CBI is a partner in producing a statewide wildlife connectivity ensemble model and the associated mapped data in support of a connectivity action plan for the state, which is still under development. The modeling aims to identify priority areas across the state in need of some form of mitigation to promote wildlife connectivity and reduce wildlife/vehicle collisions at the same time.
CBI ASSOCIATES PROGRAM
CBI Associates program was created to allow the organization to partner with researchers and scientists working in the fields of conservation and climate change, to further our reach and impact of science and technology in these fields. In 2024, CBI added two new partners to its Associates lineup. Dr. Chas Jones has been a trusted partner to Tribes & Indigenous Peoples for 25 years and is nationally recognized as an expert in matters of Tribal Climate Resilience. Dr. Sam Roy is the Creator and Founder of the Awesome Google Earth Engine Community Catalog and serves as the CEO of Spatial Bytes LLC specializing in geospatial data, workflows and analysis. He is currently working with CBI to develop remote sensing models in support of the USDA Conservation Reserve Program.
ALLIANCE OF WORLD SCIENTISTS

In 2024, CBI partnered with the Alliance of World Scientists, an international assembly of scientists who pool their knowledge, research and networks to raise awareness about the consequences of the climate crisis in order to help stem the continuing degradation of the planets life support systems. As stewards of human knowledge and champions of evidence-based decision making, the goal of the Alliance is to be an amplifying voice for scientists all over the world of these unprecedented threats.
COP16

In 2024, CBI was honored to be granted credentials to attend the 16th Conference of the Parties to the Convention on Biological Diversity (COP16) hosted in the city of Cali, Colombia. While in Cali, CBI co-hosted three well-attended panel discussion events, composed of international practitioners with deep experience in the fields of habitat connectivity and linear infrastructure development, renewable energy planning & development and wildfire research and mitigation. The relationships formed during the event are priceless, and CBI expects to collaborate with a number of the international research, government and NGO organization we met in Cali, to expand the reach of our knowledge, data and tools to other parts of the world.
Wildfire in Latin America
If you’ve been following Conservation Biology Institute’s work, you already know that wildfires are essential processes in many ecosystems, playing a fundamental role in sustaining and evolving biodiversity. However, rapid global changes in climate, vegetation, land use, and land management are shifting fire regimes beyond their natural variability ranges. As a consequence, extreme wildfires are becoming increasingly frequent and severe, causing large-scale human, economic, and ecological losses. In recent years, the planet has witnessed disastrous fires that have significantly altered natural fire regimes impacting many species, destroyed thousands of human-built structures, displaced entire human communities, and caused severe impacts on human health due to persistent and widespread smoke.
In Latin America and the Caribbean (LAC), uncontrolled fires have transformed landscapes, significantly affecting societies, economies, and the environment. The alteration of fire regimes is leading to profound ecological transformations, particularly in the tropical areas of the continent, posing serious threats to biodiversity and driving species extinction. Wildfires are also altering essential ecosystem services on which humans depend, such as clean air and water supply, soil stability and fertility, climate regulation, numerous cultural services, and more. While climate change is driving the frequency and severity of wildfires, wildfires themselves impact climate change by releasing significant amounts of greenhouse gases and causing the reduction of previously stable carbon sinks.

While LAC may seem far away to many of us that live in the northern hemisphere, the impacts of these wildfires are far-reaching. For example, the Amazon is a critical part of the health of the entire planet. Here are just a few ways that the health of the Amazon forests are critical across the globe:
- It is one of the planet’s largest carbon sinks, storing 150B metric tons of carbon, equivalent to 10 years worth of global fossil fuel emissions. Even if the world reduced human-caused emissions enough to get on track to fulfill the Paris Climate Agreement, keeping global warming below a 1.5-degree-C increase from pre-industrial levels, loss of just 20-25% of the Amazon and its stored carbon would put that target out of reach.
- Crops across the planet are dependent on the power of the Amazon’s hydrologic cycle – the forest releases 20B tons of water into the atmosphere each day. Without this, droughts are likely to become significantly more severe in agricultural areas across the globe.
- If you or someone you love has had cancer, they’ve likely been treated with medications that are derived from the Amazon. Of the plants deemed to be useful in the treatment of cancer, 70% only grow in tropical rainforests.
- Those with heart disease in your life are likely taking an ACE Inhibitor medication. This particular medication’s ingredients are derived from a viper species that is native to the Amazon.
- If you like pineapple, chocolate, sweet potatoes and coffee, odds are that what you’re eating is from tropical regions of Latin America.

Despite these challenges, LAC’s technical and financial capacity to address wildfires is limited. There is an urgent need to strengthen governmental agencies, fire brigades, and local communities with effective prevention, management, and recovery tools and strategies. Interdisciplinary research is required to understand and address the geographically varying causes and consequences of fires, as well as to develop regional systems for collecting and analyzing data to support evidence-based decision-making.
Conservation Biology Institute has partnered with the Academia Nacional de Bomberos de Colombia (Colombian National Firefighting Academy), to establish the Centro de Conservación Biológica de Operaciones Forestales (CCBOF- Latin American Center for Biological Conservation and Forest Operations) in Cali, Colombia. The center will develop novel wildfire research, consolidate existing scientific knowledge and data, educate community members on wildfire risk reduction and response, as well as train firefighters in the latest wildfire management approaches. When it is established, CCBOF will be the only resource of its kind in all of LAC.
While we believe we will be able to secure large financial sponsorship from international development banks and foundations, the effort to obtain this financing takes time and resources. CBI has almost never asked for donation dollars in the past, but this effort is so crucial to the health of the planet, and action must be taken swiftly, so- we are asking you for your help. Any amount you can give will get us one step closer to helping LAC build wildfire resiliency for their forests, communities and biodiversity. Thank you in advance for your generosity!
