Wildfire Aftermath: How Wildlife Adapts and the Role of Conservation in a Changing Climate

The Aftermath of Wildfires: A Challenge and Opportunity for Wildlife

Stark images of California’s wildfires have once again gripped the world’s attention. Among the devastation, photographs emerged of a baby deer navigating the smoky landscape and a desert tortoise roaming amidst evacuees. While the immediate dangers of fire, including smoke inhalation and heat stress, pose threats to humans and animals alike, research suggests that surprisingly few animals perish directly from wildfires. Instead, the aftermath—marked by the loss of shelter, food, and water—presents the greatest challenge for survival.

Fire as a Natural Process

For humans, wildfires can be catastrophic, destroying homes, infrastructure, and economies. The January 2025 wildfires in Los Angeles alone caused damages exceeding $135 billion. However, fire is a natural phenomenon that many ecosystems have adapted to over millennia.

Morgan Tingley, a professor of evolutionary biology at UCLA, emphasizes that fire is integral to many habitats, such as California’s chaparral and northern forests. While some animals escape by running, burrowing, or seeking shelter in treetops, others, like Australia’s echidnas, enter a hibernation-like state called torpor until the danger passes.

Fire not only shapes landscapes but also fosters biodiversity. Many species rely on post-fire conditions for reproduction and sustenance. Pollinators, for instance, thrive after moderate fires as the exposed ground encourages diverse plant growth.

Wildlife and Pyrodiversity

Wildfires create a patchwork of habitats, known as pyrodiversity, which benefits various species. The black-backed woodpecker, a quintessential post-fire bird in western North America, feeds on the insects inhabiting charred trees and excavates nesting hollows. These cavities subsequently house other species essential for forest regeneration, such as seed-dispersing birds and insectivores.

Similarly, the gopher tortoise of Florida digs deep burrows, providing refuge for over 350 other species. This illustrates the intricate ways animals contribute to ecosystem recovery post-fire.

An Increasing Threat

Despite nature’s resilience, escalating wildfire severity and frequency—exacerbated by climate change—threaten even well-adapted species. The 2020-2021 California megafires impacted over 500 vertebrate species, with the long-toed salamander losing 14% of its habitat. Though the salamander often survives the initial fire, research suggests it struggles in the following decades due to habitat loss and altered environmental conditions.

Pollinators, crucial for plant regeneration, are also vulnerable. While moderate fires benefit them, severe burns diminish their populations, reducing pollination and slowing forest recovery.

Smoke, another byproduct of wildfires, has poorly understood but potentially severe effects on wildlife. Projects like Project Phoenix are currently investigating its impact on bird populations across the western U.S.

Climate Change and Forest Management

Human activity has altered fire dynamics. Climate change contributes to drier vegetation, while invasive species—such as buffelgrass in Arizona—fuel more intense fires, endangering native flora and fauna. The 2020 Bighorn Fire, for example, devastated mature saguaro cacti in the Sonoran Desert, an ecosystem unaccustomed to severe wildfires.

Forest management practices also play a critical role. Commercial forestry, characterized by evenly spaced trees of similar age, creates homogenous landscapes more prone to large-scale burns. Moreover, the suppression of natural fires has led to excessive fuel accumulation. Indigenous communities once mitigated this risk through prescribed burns, a practice that is now being reconsidered as a viable fire management strategy.

The Role of Wildlife in Fire Recovery

Some researchers advocate rewilding as a method to manage wildfire risks. Reintroducing large herbivores, such as bison or deer, can reduce fuel loads by consuming dry vegetation. Studies from Australia suggest that restoring native ecosystem engineers, like numbats and wallabies, can influence fire behavior by altering ground cover and vegetation density.

Artificial wildlife refuges—such as wire-mesh bunkers used in Australian fire zones—have shown mixed success. While they provided temporary shelter for small animals, they did not significantly increase biodiversity post-fire, highlighting the complexities of intervention strategies.

The Path Forward

Experts caution against over-reliance on any single approach. While restoring biodiversity may help manage fire-prone landscapes, prescribed burns remain the most effective tool for mitigating wildfire severity. Tingley stresses the need for large-scale prescribed burns to restore natural fire cycles, reducing catastrophic blazes while maintaining healthy ecosystems.

The black-backed woodpecker’s struggle to adapt to increasingly extreme fires serves as a warning: even species that evolved to thrive in post-fire landscapes are facing unprecedented challenges. As fires intensify, biodiversity loss could further destabilize ecosystems, increasing the frequency and severity of future wildfires.

The interconnectedness of fire, climate change, and wildlife underscores the urgent need for proactive management. By embracing Indigenous fire practices, protecting natural refuges, and fostering resilient ecosystems, we can mitigate wildfire impacts—ensuring that both humans and wildlife have a future in fire-prone landscapes.
