In 2019, the Trump administration finalized significant revisions to the Endangered Species Act (ESA), narrowing the scope of federal protections for wildlife habitats. These regulatory changes altered how the U.S. Fish and Wildlife Service and the National Marine Fisheries Service evaluate the impact of industrial development, infrastructure projects, and climate change on species listed as threatened or endangered.
Regulatory Changes to the Endangered Species Act
The 2019 rule changes, implemented under then-Secretary of the Interior David Bernhardt, introduced several shifts in how the federal government manages protected lands. According to the U.S.
Key revisions included:
- Designation of Critical Habitat: The administration narrowed the definition of "occupied habitat," making it more difficult to protect areas that a species might need to migrate to as climate change alters their current ranges.
- Threatened Species Protections: The rule removed the "blanket" protections that automatically granted threatened species the same level of safeguards as those classified as endangered, requiring instead that protections be determined on a case-by-case basis.
Impact on Habitat Development
Critics and environmental organizations argued that these changes created a "death sentence" for vulnerable species by prioritizing industrial expansion over habitat preservation. According to reporting by The New York Times, the changes made it easier for the government to approve mining, logging, and drilling projects in areas previously restricted due to the presence of protected wildlife.
