| | Title | Species decline: contaminants and other contributing factors |
| | Project Description | Members of over 1,200 taxa have been listed as Threatened or Endangered, and over 4,000 |
| | additional organisms have been identified for listing as Candidate Species or Species of Concern. |
| | Both naturally-occurring and human activities (e.g., environmental contaminants and pollution) |
| | have been shown to be a major factor in the decline of many species. The purpose of this project |
| | is to develop a database that lists and ranks the presumed causes of these declines, with special |
| | emphasis on contaminants and pollutant-related situations. This will be accomplished by |
| | reviewing the U. S. Fish and Wildlife Services approved recovery plans for the reasons which lead |
| | to listing and for the information and management actions needed to bring about recovery. These |
| | factors will be itemized, cross-referenced, enumerated, and categorically ranked (e.g., |
| | phylogenetic, anthropogenic, habitat, contaminant). Particular attention will be given to factors |
| | which impact numerous species or are particularly detrimental to specific taxonomic groups. |
| | Listing packages will serve as a secondary source of information. |
