Definition of Threatened and Endangered Marine Mammals:

Some marine mammals face significant threats. The Endangered Species Act (ESA) aims to conserve endangered and threatened species and the ecosystems they depend on. Under the ESA, a species is considered endangered if it is in danger of extinction throughout all or a significant portion of its range, or threatened if it is likely to become endangered in the foreseeable future.  We present the annual number of threatened and endangered marine mammals in all regions except the Caribbean. Data for the Southeast and Gulf of Mexico regions are combined.

Data:

Summary data tables from the NOAA Fisheries Protected Resources Species Information System were obtained from the database manager 3 April 2020. The number of ESA threatened and endangered species were summed for each region by year.

 

 

Definition of Strategic Stocks in the Marine Mammal Protection Act:

A strategic stock is defined by the Marine Mammal Protection Act as a marine mammal stock—For which the level of direct human-caused mortality exceeds the potential biological removal level; Which, based on the best available scientific information, is declining and is likely to be listed as a threatened species under the Endangered Species Act within the foreseeable future; or Which is listed as a threatened or endangered species under the ESA, or is designated as depleted under the MMPA. A depleted stock is defined by the MMPA as any case in which—The Secretary of Commerce, after consultation with the Marine Mammal Commission and the Committee of Scientific Advisors on Marine Mammals established under MMPA title II, determines that a species or population stock is below its optimum sustainable population; A State, to which authority for the conservation and management of a species or population stock is transferred under section 109, determines that such species or stock is below its optimum sustainable population; or A species or population stock is listed as an endangered species or a threatened species under the ESA. We present the annual number of strategic and depleted marine mammals in all regions except the Caribbean. Data for the Southeast and Gulf of Mexico regions are combined.
