Protect Beavers to Fight Climate Change

Beavers are not just wildlife—they are one of our most powerful, cost-effective allies in the fight against climate change. Yet across the United States, outdated policies still treat them as nuisances to be killed instead of the ecological engineers we urgently need.

New research published March 18 in Communications Earth & Environment and highlighted by USA Today delivers a breakthrough: for the first time, scientists have measured both the carbon pollution released and the carbon captured by beavers as they reshape wetlands—revealing just how powerful their climate impact can be.

This research is a game-changer. It shows that beaver-built wetlands can store extraordinary amounts of carbon—about 1,194 tons over 13 years in one documented case—underscoring their powerful role in reducing climate pollution. By reshaping landscapes, beavers significantly boost an ecosystem’s ability to capture and retain carbon compared to areas without them.

These wetlands deliver even more benefits: they reduce wildfire risk, improve water quality, and create critical habitat for countless species. That’s why scientists and land managers increasingly refer to beavers as “nature’s firefighters,” as their wetlands act as natural firebreaks that can slow—or even stop—devastating wildfires.

In other words, beavers are a natural climate solution already working for free.

But despite these enormous benefits, beavers are still widely trapped, killed, or removed. State wildlife agencies often prioritize short-term infrastructure concerns over long-term climate resilience—ignoring science that shows coexistence is not only possible, but essential.

We can no longer afford to overlook this solution.

We call on state wildlife agencies to:

• End the lethal management of beavers except as a last resort

• Invest in coexistence tools and conflict mitigation

• Support beaver reintroduction and habitat restoration

• Integrate beavers into state climate and water management plans

At a time when climate solutions are often expensive and slow to implement, beavers offer something rare: a proven, immediate, and self-sustaining way to restore ecosystems, store carbon, and even help defend communities from wildfire.

Protecting beavers isn’t just about wildlife—it’s about securing a livable future.

State leaders must act now. Please sign the petition calling on wildlife agencies to protect and restore beaver populations as a proven, natural climate solution—one that stores carbon, safeguards water supplies, and strengthens ecosystems in the face of worsening drought and wildfires.

The petition to state wildlife agencies reads: Protect beavers as a vital, natural climate solution by ending routine lethal management and investing in coexistence strategies. New research shows that beaver-built wetlands store significant carbon while reducing drought, wildfire risk, and ecosystem collapse. We urge you to support beaver restoration and integrate their benefits into state climate and water management plans.
