The Trump administration finalized a rule on Friday that repeals a crucial part of the Endangered Species Act (ESA), removing protections for habitats of imperiled wildlife and opening these areas to logging, mining, and development.
Rule Change Removes Habitat from 'Harm' Definition
For 50 years, the ESA defined 'harm' to include not only direct injury or killing of listed species but also modification of their critical habitats. This interpretation was upheld by the Supreme Court in 1995, supporting protections for old-growth forests relied on by endangered spotted owls. The new rule rescinds that broader definition, citing 'regulatory intrusion that interfered with private property rights.'
Impact on Species and Extinction Risk
Habitat destruction is the leading driver of species loss. The ESA has safeguarded over 1,700 species, preventing 99% of listed species from going extinct, including the bald eagle. Experts warn the change could be catastrophic for already vulnerable species. Earthjustice attorney Kristen Boyles stated, 'For the first time ever, a presidential administration now claims that species protected by the Endangered Species Act shouldn’t be safe from habitat modification that destroys where they live, raise their young, or search for food.'
Stephanie Kurose of the Center for Biological Diversity called the proposal 'a death sentence for wolverines, monarch butterflies, Florida manatees and so many other animals and plants that desperately need our help.'
Extinction Emergency and Broader Ecosystem Threats
The rule change comes amid a global extinction crisis. A 2019 IPBES assessment found roughly 1 million species threatened with extinction, including 40% of amphibians and a third of reef-forming corals, marine mammals, and sharks. Insects, foundational to ecosystems, are in rapid decline, with 80% of species yet unidentified. Habitat modification triggers domino effects, where loss of one species leads to extinctions of dependent species.
Public Opposition and Political Context
Public support for species protections remains strong. A 2023 poll showed 80% of registered voters favor full ESA funding, and 73% view biodiversity as important to their daily lives. Despite over a hundred thousand public comments opposing the change, the administration moved forward. Interior Secretary Doug Burgum accused federal agencies of abusing the ESA to 'obstruct lawful land use and burden American families and businesses,' claiming the rule aligns with the law's original intent. Officials said direct injury or killing of listed wildlife remains prohibited.
Broader Deregulatory Push and Legal Challenges
This rule is part of a broader effort by President Trump to dismantle endangered species protections to boost energy extraction and industrial access. In March, Trump convened the 'God squad' to expand oil and gas operations in the Gulf of Mexico. Advocates are preparing legal challenges. Boyles stated, 'Let’s be clear: there is no support for the Trump Administration’s rule – no scientific support, no legal support, no public support. We will see the Trump Administration in court.'
