American Burying Beetle ('Nicrophorus americanus') Recovery Plan.

摘要

Nicroplzonis americanus, formerly distributed throughout temperate eastern North America, now persists in only two widely separated natural populations: a small but apparently stable population on Block Island off the coast of Rhode Island, and a lower-density but more widespread population in eastern Oklahoma. In addition, three laboratory colonies are being maintained, and in 1990 and 1991, about 90 N. anzericanus were reintroduced to historical habitat on Penikese Island, Massachusetts. Based on the drastic decline and extirpation of the species over nearly its entire historical range, the American burying beetle was listed as endangered in July 1989.
