Twenty states and the District of Columbia have taken the Trump administration to federal court to challenge the new rules underthe Endangered Species Act, the law passed by Congress in 1973. The lawsuits come less than two months after the Departments of the Interior and Commerce announced the new regulations.
What This Means for Habitats
The first controversy concerns the definition of “harm.” For the states, the new interpretation narrows a protection that for decades has also considered habitat alteration a threat to protected species. The new rules would allow activities such as oil drilling and mining when they are not “directly and intentionally” aimed at specific animals, even if they may injure or kill them by altering their environment.
The second lawsuit challenges two provisions: one eliminates general protections for species newly classified as threatened, except for specific measures taken by the Fish and Wildlife Service; the other requires that objections raised by businesses—including potential economic costs—be considered before designating certain areas as “critical habitat.”
The states describe the new regulations as “a reversal of course of staggering proportions” and “arbitrary and capricious.” They also argue that they violate the National Environmental Policy Act.
A law with measurable results
The Endangered Species Act is one of the cornerstones of American conservation. According to reports, 99% of the species protected by the law have avoided extinction. Among the examples cited are the bald eagle, the California condor, the grizzly bear, and the humpback whale.
The dispute centers on the criteria the federal government uses to evaluate a territory when its protection conflicts with economic activities. The habitat thus becomes the crux of the debate between wildlife protection and development.
The Administration’s Defense
The Department of the Interior rejects the allegations. A spokesperson argues that federal agencies must enforce the Endangered Species Act “as written,” without expanding its scope. The department views the lawsuit as an attempt to preserve “excessive regulation” that has accumulated over the past few decades.
Secretary of the Interior Doug Burgum accused the law of having been “exploited” to block numerous projects, with repercussions for competitiveness and costs for Americans. According to the administration, the new rules restore the legislation to its original intent.
The clash follows the Supreme Court’s 2024 decision overturning the previous precedent—in effect for about forty years—regarding federal agencies’ interpretations.
The lawsuits, filed in federal courts in the San Francisco area, are part of a broader series of state challenges to the environmental policies of Trump’s second term. The outcome could affect areas where conservation, energy, mining, and economic development intersect.
