The Trump administration officially revoked a significant provision of the Endangered Species Act (ESA) on Friday, implementing a new regulation that permits the development of habitats critical for endangered wildlife, including logging, mining, and other activities.
For half a century, this pivotal environmental law encompassed a comprehensive interpretation of “harm,” which protected not only the species themselves but also the essential habitats necessary for their survival. This broader definition was affirmed by the Supreme Court in 1995, which supported the conservation of old-growth forests relied upon by endangered species such as the spotted owl.
Despite substantial public backing for a robust ESA and hundreds of thousands of comments opposing the changes, the Department of the Interior and the Department of Commerce redefined the term as a form of “regulatory intrusion” that infringed upon private property rights, leading to the decision to rescind it.
Habitat destruction is widely recognized as the primary factor contributing to species extinction. The ESA has played a crucial role in protecting over 1,700 species and their habitats, ensuring that 99% of those listed do not face extinction, with the bald eagle being a prominent success story. Experts express concern that this regulatory shift could have dire consequences for species already on the verge of disappearing.
“For the first time in history, a presidential administration is asserting that species safeguarded by the Endangered Species Act are not protected from habitat changes that can destroy their living conditions, breeding grounds, or food sources,” stated Earthjustice attorney Kristen Boyles.
Stephanie Kurose, deputy director of government affairs at the Center for Biological Diversity, remarked that this initiative would spell “a death sentence” for various species, including wolverines, monarch butterflies, and Florida manatees, when the proposal was first introduced last year.
This weakening of regulations occurs during a time of urgent extinction crisis, exacerbated by the climate emergency. According to a 2019 report from the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES), approximately 1 million species face extinction, including nearly 40% of amphibians and a third of marine mammals, reef-forming corals, and sharks.
Insects, which are vital to biodiversity and form the foundation of numerous ecosystems, are experiencing a rapid decline. Approximately 80% of insect species remain unidentified, with some disappearing before they can even be classified.
Changes to habitats can endanger interconnected species and ecosystems. Alterations to landscapes can initiate a catastrophic chain reaction, where the extinction of one species results in the loss of others reliant on it.
The American public largely supports species conservation. A poll conducted in 2023 indicated that 80% of registered voters endorsed full funding for the ESA, while 73% consider biodiversity integral to their daily lives.
However, officials from the Trump administration argue that the regulations were amended to better reflect what they perceive as the law’s original intent. Interior Secretary Doug Burgum stated that federal agencies had misused the ESA to “hinder lawful land use and impose burdens on American families and businesses,” claiming that the existing protections had transformed routine activities into regulatory obstacles.
In their announcement, officials emphasized that “actions that directly harm or kill listed wildlife will still be prohibited.”
Nevertheless, these changes are part of a broader deregulatory agenda by Donald Trump, who has prioritized dismantling endangered species protections to enhance energy extraction and industrial activities, even in the nation’s most sensitive natural habitats.
In March, the president assembled a group informally known as the “God squad,” tasked with making critical decisions regarding species survival, to facilitate oil and gas operations in the Gulf of Mexico. At the beginning of his second term, Trump appointed top federal officials to this group to identify methods for bypassing ESA regulations that pose “obstacles to domestic energy infrastructure.”
Conservation advocates are already gearing up to contest the new interpretation of harm. “Let’s be clear: there is no support for the Trump Administration’s rule—neither scientific, legal, nor public backing,” Boyles declared. “We will see the Trump Administration in court.”
