California condors in the Pacific Northwest : integrating history, molecular ecology, and spatial modeling for reintroduction planning

Creator:: D'Elia, Jesse
Abstract:: Reintroduction programs are increasingly being used to save animals from extinction and aid in their recovery. The California Condor (Gymnogyps californianus), one of the most endangered birds in the world, is a remarkable example of how reintroduction programs can help rapidly increase a species' population numbers and range following a...

Use of range sites by pronghorns in south central Oregon

Creator:: Herrig, Daniel M.
Abstract:: Relative use by pronghorns (Antilocapra americana) of 16 range sites was studied during summer and fall of 1971 and 1972 on Hart Mountain National Antelope Refuge, an area of high desert rangeland in south central Oregon. A Relative Use Index was developed based upon 1533 observations of pronghorns located on...

Daily activity patterns, survival, and movements of red tree voles (Arborimus longicaudus) in western Oregon

Creator:: Swingle, James Kerr
Abstract:: We radiocollared a sample of 61 red tree voles in Douglas County, Oregon and monitored their movements to determine daily, seasonal, and sexual differences in behavior and home range attributes. We also collected information on nest attributes, survival, and dispersal of the radiocollared voles. Individual voles were monitored for periods...
Resource Type:: Masters Thesis
Full Text:: variation in home range size was explained by the sex or age of voles or by forest age. Two Redacted for

Ecological Effects of Tide Gate Upgrade or Removal: A Literature Review and Knowledge Synthesis - Final report

Creator:: Giannico, Guillermo, Souder, Jon, Tomaro, Londi, and Behan, Jeff
Abstract:: This document reports on findings, conclusions and recommendations derived from scientific literature and knowledge regarding the effectiveness of tide gate removal or upgrade in improving conditions for Oregon’s native migratory fish species, particularly salmonids, and other plant and animal species that utilize estuarine ecosystems. The project was commissioned by the...

Historic Survival Rates and Cause-Specific Mortality for Columbian Black-Tailed Deer in Southwest Oregon

Creator:: Groot, Kevyn A.
Abstract:: 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...

Impacts of Range Management Decisions on Native Pollinators: Innovative Grazing Practices and Riparian Restoration

Creator:: Mitchell, Scott R.
Abstract:: Animal pollination is critical to plant reproduction in agricultural and wildland ecosystems. Much of the production of seeds and fruits in natural areas, which underlie many food webs, depends on pollination services by insects. The taxon responsible for delivering the bulk of these services in most temperate systems is bees....

Population and behavioral responses of small mammals to silviculture and downed wood treatments in the Oregon Coast Range

Creator:: Waldien, David L.
Abstract:: Forest managers are challenged to provide timber revenues and other resources for society while protecting and enhancing components of biodiversity that are often associated with older forests or older forest structure, such as dead wood. We examined small mammal response to timber harvest in stands 8-10 years following group-selection, two-story,...

Juvenile survival and birth-site selection of Rocky Mountain elk in northeastern Oregon

Creator:: Rearden, Spencer N.
Abstract:: With declining populations and low calf recruitment in northeastern Oregon, much interest has been generated to study the survival rates and causes of mortality of Rocky Mountain elk (Cervus elaphus nelsoni). I investigated the causes of elk calf mortality and the effects of predation risk on birth-site selection by cow...
