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.
