This study involved the use of the two-choice preference test to determine the taste reactions of buck and doe Columbian black-tailed deer (Odocoileus hemionus columbianus) to ascending concentrations of water extracts of Douglas fir, red alder, cascara, western hemlock and bitterbrush; to an ethanol extract of Douglas fir, and to...

These data were obtained from GPS radio collared mule deer from 2015-2017 in the John Day Basin. The dataets includes location data for used vs available predictor variable information for time since fire, juniper canopy cover, NDVI, and vegetation community for winter, summer:migratory, summer:resident seasonal ranges. The datasets were used...
In contrast with other Odocoileus species, Columbian black-tailed deer (Odocoileus hemionus columbianus) population dynamics are not well understood throughout the species’ range. Concerns over apparent long-term population declines have prompted efforts to fill basic knowledge gaps including estimates of vital rates (fecundity, recruitment and survival) and cause-specific mortality. The Oregon...
Mule deer (Odocoileus hemionus) populations in south-central Oregon are near their lowest levels since census efforts began in 1961. I investigated fawn survival, cause-specific mortality, and factors contributing to mortality from 2010 – 2012 to identify potential causes for the decline. I also explored pre-parturition and parturition site characteristics.
I...
A wildfire burned over 40,000 ha of conifer and mixed conifer-hardwood forest in
the Silver Creek drainage of southwestern Oregon in the fall of 1987 allowing me to
assess big game use of a large natural burn. I used fecal pellet group counts to estimate
habitat use and effects of...
