Habitat use and survival of Columbian Black-tailed deer in Western Oregon


August 2018 - June 2020


Black-tailed deer (Odocoileus hemionus columnbianus) populations and hunter harvest trends have declined in Oregon since 1994. The Oregon Department of Fish and Wildlife (ODFW) is concerned with this decline and has identified current knowledge gaps regarding black-tailed deer ecology in Oregon that are necessary to facilitate ODFW’s management of this species. To address these knowledge gaps, ODFW initiated a large-scale, long-term black-tailed deer research project in the fall of 2011 that included the attachment of VHF and GPS radio-collars to adult deer. In 2016, a separate study was initiated to investigate fawn survival in southwestern Oregon and VHF radio-transmitters were attached to a sample of newborn fawns. In collaboration with a Unit graduate student, these radio telemetry data will be used by the student to estimate seasonal and annual survival rates of black-tailed deer relative to habitat use. Information on key vital rates like survival and the factors that effect it for adults or fawns, would fill a primary knowledge gap for black-tailed deer in Oregon that will facilitate effective management by ODFW.
