Taxonomic Review of Category 2 Species, brdsar0001 - Parent Taxonomic Review Metadata
Entry ID: BRDSAR0001

Abstract: More than 1,600 species and subspecies of animals in the United States are
presently proposed for listing as endangered or threatened. These taxa are

Purpose: The occurrence of such problems can be minimized through Taxonomic
Validation, which will do the following:
