Listing priority number
A listing priority number is a
Endangered Species Act
, but due to funding concerns, cannot be listed immediately.
Every candidate species is assigned a priority number from 1 to 12 based on factors such as the magnitude of threats facing the species, the immediacy of the threat and the species' taxonomic status. A lower priority number means that the species is under greater threat. For example, a number of 2 indicates a higher degree of concern than a number of 8.
The following table shows how the FWS determines listing priority numbers.
Threat Magnitude | Immediacy | Taxonomy | Priority Number |
---|---|---|---|
High | imminent | monotypic genus | 1 |
species | 2 | ||
subspecies/population | 3 | ||
non-imminent | monotypic genus | 4 | |
species | 5 | ||
subspecies/population | 6 | ||
Moderate to low | imminent | monotypic genus | 7 |
species | 8 | ||
subspecies/population | 9 | ||
non-imminent | monotypic genus | 10 | |
species | 11 | ||
subspecies/population | 12 |
