The Trump administration has quietly weakened two core provisions of the Endangered Species Act, removing automatic penalties for destroying habitat and narrowing the definition of 'take' to only intentional killing. These changes, which follow an internal memo, effectively eliminate a key tool that has helped bring nearly 300 species back from the brink of extinction since the law's passage.
Among the species most at risk is the North Atlantic right whale, whose population has fallen to roughly 380 individuals. Their primary threats—ship strikes and fishing gear entanglement—are accidental, not intentional, so the new interpretation of 'take' could be used to justify rolling back speed limits and other protective measures. The eastern massasauga rattlesnake, listed as threatened in 2016, also faces habitat fragmentation across the Midwest, and the loss of habitat protections could further isolate already vulnerable populations.
Environmental lawyers describe the changes as an unprecedented assault on endangered species protections, one that gives industry more leeway while species struggle to adapt to climate change. As the regulatory framework weakens, the future for these and other at-risk species grows increasingly uncertain.
