Federal Register Notices

Back to Endangered Species Project

The Federal Register is the official daily publication for rules, proposed rules, and notices of Federal agencies and organizations. Federal Register notices provide useful information on endangered species including the reason for listing, key biological information, and contact persons. Listing notices from 1994 to date are available electronically below (either as text or PDF files). Earlier notices cited can be obtained in hard copy through major libraries in your area.

These federally listed and proposed endangered species are found in general proximity to pesticide use sites.

The files below are in PDF or text format. Some files are large and download times will vary with the speed of your connection.
