How does a species become listed as Endangered or Threatened?
The listing process is one of the basic functions performed by USFWS in carrying out its responsibilities under the Endangered Species Act. USFWS has developed a priority system designed to direct its efforts toward the plants and animals in greatest need of protection. In order to list, reclassify, or delist a species, USFWS must follow a strict legal process known as a “rulemaking” procedure. The rule is first proposed in the Federal Register, a US Government publication. After a public comment period, USFWS decides if the rule should be approved, revised, or withdrawn. This process encourages the participation of all interested parties, including the general public. The entire process can take up to a year or longer in unusual circumstances.
