US - Endangered Species - Part 81. Conservation of Endangered and Threatened Species

Summary: These ESA (Endangered Species Act) regulations relate to agreements with the states, or signed documented statements of the actions to be taken by the State(s) and the Secretary in furthering the purposes of the Act. The Secretary is authorized by the Act to cooperate with any State which establishes and maintains an adequate and active program for the conservation of various endangered and threatened species.

US - Endangered Species - Part 402 - Interagency Cooperation

Summary: These ESA (Endangered Species Act) regulations outline the rules for joint or interagency actions under the Act. Specifically, the regulations state that each federal agency shall confer with the Service (USFWS) on any action which is likely to jeopardize the continued existence of any proposed species or result in the destruction or adverse modification of proposed critical habitat; confer on the coordination of biological assessments and consultations; and confer regarding Fire Plan Project rules, among other things.

US - Endangered Species - Part 222 - General Endangered and Threatened Marine Species

Summary: These ESA (Endangered Species Act) regulations relate to certificate of exemptions for pre-Act endangered species part under the general regulations for endangered and threatened marine species. The Assistant Administrator may issue permits for scientific purposes or for the enhancement of the propagation or survival of the affected endangered or threatened species in accordance with these regulations. Any person to whom a Certificate of Exemption has been issued by the National Marine Fisheries Service may apply to the Assistant Administrator for renewal of such certificate.

US - Endangered Species Act - Subpart H - Experimental Populations

Summary: These ESA (Endangered Species Act) regulations relate to "experimental populations," an introduced and/or designated population that has been so designated in accordance with the procedures of this subpart but only when, and at such times as the population is wholly separate geographically from nonexperimental populations of the same species. The Secretary may designate as an experimental population a population of endangered or threatened species that has been or will be released into suitable natural habitat outside the species' current natural range (but within its probable historic range, absent a finding by the Director in the extreme case that the primary habitat of the species has been unsuitably and irreversibly altered or destroyed). Any population determined by the Secretary to be an experimental population shall be treated as if it were listed as a threatened species for purposes of establishing protective regulations under section 4(d) of the Act with respect to such population.

US - Endangered Species - Subpart E - Similarity of Appearance

Summary: This Subpart of the ESA regulations allows the designation of a species, which is not Endangered or Threatened but closely resembles an Endangered or Threatened species, as a "de facto" Endangered or Threatened species if the director of the USFWS determines the listing is necessary. Factors that influence this decision include the degree of difficulty enforcement personnel would have in distinguishing the species from an Endangered or Threatened species (including those cases where the criteria for recognition of a species are based on geographical boundaries); the additional threat posed to the Endangered or Threatened species by the loss of control occasioned because of the similarity of appearance; and the probability that so designating a similar species will substantially facilitate enforcement and further the purposes and policy of the Act.

US - Endangered Species - Subpart D. Threatened Wildlife

Summary: These Endangered Species Act regulations relate to threatened species. Included in the provisions are requirements for obtaining permits to take such species for one of the following purposes: scientific purposes, or the enhancement of propagation or survival, or economic hardship, or zoological exhibition, or educational purposes, or incidental taking, or special purposes consistent with the purposes of the Act. Also included are special rules for certain mammals, reptiles, birds, and fishes among other species.
