Post-Delisting Monitoring Report for the Douglas County Distinct Population Segment of the Columbian White-tailed Deer (Odocoileus virginianus leucurus). 2003-2008.

摘要

On March 11, 1967, the U.S. Fish and Wildlife Service (Service) listed the Columbian white-tailed deer (Odocoileus virginianus leucurus) as an endangered species under the Endangered Species Preservation Act of 1966 (FR 32 4001, USFWS 1967). At that time, the subspecies was believed to occur only along the lower Columbia River, whereas the population in Douglas County was believed to be hybridized with the Columbian black-tailed deer (ODFW 1995). On March 8, 1969, the Service included the Columbian white-tailed deer on a list of fish and wildlife species threatened with extinction under the Endangered Species Conservation Act of 1969 (FR 34 5034, USFWS 1969). Species listed as endangered on the above-mentioned lists were automatically included in the Lists of Endangered and Threatened Wildlife when the Endangered Species Act (Act) was enacted in 1973. In 1978, the State of Oregon determined white-tailed deer in the Roseburg area belonged to the Columbian subspecies (ODFW 1995). This determination resulted in the Douglas County population being considered as endangered, together with the Columbia River population. The Columbian white-tailed deer was listed as endangered by the State with the passage of the Oregon Endangered Species Act in 1987 (ODFW 1995).
