The end of endangered species habitat protections in California?

Not quite, but the combination of the Trump Admin and Prop 45 will drastically reduce protections.

California likes to portray itself as an environmental leader, and in many ways it is.  But in the context of one of the most important areas of environmental law – protecting endangered species – California is on the verge of eliminating most of its protections for the habitat of endangered species.  That is the result …

In 1987, forest cover in Costa Rica, one of the famously most biodiverse nations on the face of …

In Harm’s Way

Agency’s efforts to repeal harm definition for the ESA carries significant legal risks

The Trump Administration has finalized a rule that would eliminate the definition of harm from the regulations implementing the Endangered Species Act (ESA).  Harm is one component of the definition of take in the ESA, and Section 9 of the ESA prohibits take of members of endangered species.  As I noted last spring, when the …

Screaming in the Wilderness

A clear mountain lake surrounded by rocky terrain, pine trees, and rugged peaks under a bright blue sky with scattered clouds.

More is screaming needed.

It is no surprise that, in the past couple of weeks, the Trump Administration has moved to gut habitat protection under the Endangered Species Act, opening wilderness areas to mining and oil drilling, and to eviscerate Monument designation for most of two wilderness areas in Utah.  Trump and his allies made their intentions clear in …

Judicial Review of the Hegseth Gambit

A headshot picture of Pete Hegseth.

Hegseth and the “God Squad” may have just stepped into a morass. 

As expected, the Endangered Species Committee issued a blanket exemption, preventing any challenges to oil and gas drilling in the Gulf that threaten endangered species. Hegseth’s request for the exemption is premised on the existing (but possibly insufficient) protections that the government is currently giving endangered species. Thus, it’s not quite a license for Exxon to send out harpoon boats to kill off whales. It does, however, raise the suspicion that the current protections are grossly inadequate and that the government expected to lose in court, before in effect breaking the glass and pulling the red emergency lever.

Dear UNFCCC, Subnational Governments are Key to Protecting Forests

Challenging Hegseth’s National Security Gambit

A headshot picture of Pete Hegseth.

Hegseth may not have as much power as he thinks to run roughshod over the Endangered Species Act.

According to a DOJ filing, “[o]n March 13, 2026, the Secretary of War notified the Secretary of the Interior that the Secretary of War found it necessary for reasons of national security to exempt from the ESA’s requirements all Gulf of America oil and gas exploration and development activities.”   It’s difficult but not impossible to challenge the government on issues of national security.  Hegseth’s demand for an exemption to allow oil companies to destroy endangered species is a bold, aggressive move, much like the decision to go to war against Iran.  As with the war itself, however,  the legal and political aftermath may prove a lot messier than the Administration is anticipating. Here are some possible arguments that could potentially limit Hegseth’s powers.

Harming Species

The impact of repealing the ESA Section 9 prohibition on habitat destruction will be large for many endangered species.

As I posted last year, the Trump Administration is proposing to repeal an Endangered Species Act (ESA) regulation that limits destruction of habitat for listed species.  Specifically, the proposal is to repeal the definition of “harm” in the regulations.  That regulatory definition includes some forms of habitat destruction within the meaning of harm.  And “harm” …
