Rescinding the ESA definition of harm: (www.federalregister.gov/documents/20...)
Please submit a comment on the Federal Register. You have until May 19. This would backtrack case law, represent an agency overruling the US Supreme Court, and would be incredibly damaging to biodiversity.

Conservation is using eDNA more and more. A paper just came out describing how Elkhorn Slough led an effort to sample for amphibians and enlist more private landowners. I chat about the paper with UCLA herpetologist Brad Shaffer.

I turned 18 just 3 months before the 1976 Presidential election. I felt proud to have had the opportunity to vote for Jimmy Carter. And have been grateful ever since that he was elected and became our nations greatest post-presidency statesman, IMHO.
