Thank you for your interest in the Letter from Biologists to the United States Senate Concerning Science in the Endangered Species Act. The letter with 5,738 signatures was hand-delivered to each senator’s office on Wednesday, March 8, 2006. Several scientists were in Washington, D.C. to personally deliver the letter to key senators and their staff and to discuss the importance of science to species protection. In more than a dozen additional states, scientists’ personalized cover letters accompanied the biologists’ letter and signatures.

The efforts to protect science in the Endangered Species Act continue and will likely extend into the next session of Congress. Although we do not currently have specific plans, an opportunity may arise in the future to re-deliver the letter with additional signatures. If you would like to add your name for consideration as a letter signer, fill out the form below. We will keep you informed if any additional steps are required on your part.

If you have any questions about your signature on this statement contact Jean Sideris via email at ssi@ucsusa.org or by phone at (617) 547-5552. 

The letter is open to biologists with or working towards an advanced degree. In addition, on a case-by-case basis, we will consider those who have extensive life experience working in the field that gives them particular knowledge of species and their habitats. Please use Specialization field to describe further.
