Endangered Species Act - Listing Status

Listing Status

Listing status and its abbreviations used in Federal Register and by federal agencies:

  • E = endangered (Sec.3.6, Sec.4.a) - any species which is in danger of extinction throughout all or a significant portion of its range other than a species of the Class Insecta determined by the Secretary to constitute a pest.
  • T = threatened (Sec.3.20, Sec.4.a) - any species which is likely to become an endangered species within the foreseeable future throughout all or a significant portion of its range
Other categories:
  • C = candidate (Sec.4.b.3) - a species under consideration for official listing
  • E(S/A), T(S/A) = endangered or threatened due to similarity of appearance (Sec.4.e) - a species not endagered or threatened, but so closely resembles in appearance a species which has been listed as endangered or threatened, that enforcement personnel would have substantial difficulty in attempting to differentiate between the listed and unlisted species.
  • XE, XN = experimental essential or non-essential population (Sec.10.j) - any population (including eggs, propagules, or individuals) of an endangered species or a threatened species released outside the current range under authorization of the Secretary. Experimental, nonessential populations of endangered species are treated as threatened species on public land, for consultation purposes, and as species proposed for listing on private land.

Famous quotes containing the word status:

    Anthropologists have found that around the world whatever is considered “men’s work” is almost universally given higher status than “women’s work.” If in one culture it is men who build houses and women who make baskets, then that culture will see house-building as more important. In another culture, perhaps right next door, the reverse may be true, and basket- weaving will have higher social status than house-building.
