The California ESA and habitat protection

How California can fill in for a reduction in federal protection for endangered speciees

What’s the Harm?

Tentative thoughts on Trump Administration’s proposed repeal of the ESA regulation defining harm

The administration has proposed revoking the definition of harm in the regulations implementing Section 9 of the Endangered Species Act (ESA).  Section 9 is the section of the ESA that prohibits taking a member of a listed species.  The change is significant because that definition of harm included, in some circumstances, actions that modify the …

Precedent, the Trump Administration, and Endangered Species

A new Trump Administration initiative misinterprets the overruling of Chevron

The Trump Administration’s effort to strip away protections under the Endangered Species Act that had previously been upheld by the Supreme Court. The Administration seems to think they’re entitled to ignore that earlier decision because it was decided under the Chevron test and Chevron has since been overruled. They’re wrong. If it wishes to change the existing interpretation, the agency must give a reasoned argument for doing so that discusses the relevant policy issues, including reliance and the impact of its decision on endangered species.

Pearl Harbor Today

82 years after the attack, what is the state of the harbor?

Today is Pearl Harbor Day, the anniversary of the Japanese attack that launched the U.S. into World War II.  Those of us who don’t live in Hawaii may not think much about the harbor, but I started to wonder how things were going environmentally there. The geography is more complex than I had expected. I …

St. Valentine’s Other Assignment

Along with lovers, couples, and marriage, he has a more environmental domain.

St. Valentine is associated with love and romance. He is also the patron saint of beekeepers. It’s unclear why. Maybe it’s the association of honey with happiness and affection, especially in the age before chocolate reached Europe.

Scenarios and Uncertainty

Imagining different futures can be the best way to think through options when we don’t know the odds.

In environmental law, we’re often operating at the limits of knowledge about the natural world and human behavior.  Climate change is well understood in some ways, but it will set off a chain of reactions that we only partly understand.  It’s also difficult to predict the future of ecosystems, future energy prices, technological changes, and …
