Endangered, Threatened, and Depleted Marine Mammals in U.S. Waters. A Review of Species Classification Systems and Listed Species

摘要

In its 2004 appropriations bill, Congress directed the Marine Mammal Commission to 'review the biological viability of the most endangered marine mammal populations and make recommendations regarding the cost-effectiveness of current protection programs.' The report identifies 'the most endangered marine mammal populations' in U.S. waters, evaluates the criteria and methods used to place marine mammal species and populations on the major protected species lists, and review current data on their biological status.
