Terrestrial lichen and bryophyte communities of the Blue Mountains in Northeast Oregon

Creator:: Hardman, Amanda
Abstract:: Although terrestrial lichens and bryophytes are common in upland plant communities of the Blue Mountains in northeast Oregon, research on cryptogam communities in this region is wanting. Studies have shown that lichens and bryophytes can reduce soil erosion and increase soil fertility in other semiarid habitats of North America. Understanding...

Riparian vegetation composition and structure associated with channel morphology of headwater meadow streams in the Blue Mountains, northeast Oregon

Creator:: Toledo, Zachary O.
Abstract:: Relationships between the structure and composition of riparian vegetation with channel morphology were examined in three montane meadow streams in the headwaters of the Upper Grande Ronde River and North Fork John Day River in the Blue Mountains, northeast Oregon. Vegetation composition, root biomass, and channel morphology cross-sections were sampled...

Starkey Project : history facilities, and data collection methods for ungulate research

Creator:: Rowland, Mary M., Bryant, Larry D., Johnson, Bruce K., Noyes, James H., Wisdom, Michael J., and Thomas, Jack Ward
Abstract:: In the 1980s, resource managers were increasingly concerned about effects of timber harvest on ungulates in National Forests. Land and resource management plans incorporated restrictions on timber harvest to maintain cover for Rocky Mountain elk (CeNus e/aphus ne/soni V. Bailey) and mule deer (Odocoileus hemionus hemionus RafinesqueJ, and habitat models...

Modification of Mixed-Conifer Forests by Ruminant Herbivores in the Blue Mountains Ecological Province

Creator:: Riggs, Robert A., Tiedemann, Arthur R., Cook, John G., Ballard, Teena M., Edgerton, Paul J., Vavra, Martin, Krueger, William C., Hall, Frederick C., Bryant, Larry D., Irwin, Larry L., and Delcurto, Timothy
Abstract:: Secondary plant succession and the accumulation of biomass and nutrients were documented at seven ruminant exclosures in Abies and Pseudotsuga forests variously disturbed by logging, burning, and grass seeding. Long-term (25 or more years) foraging by Rocky Mountain mule deer (Odocolleus hemionus) and Rocky Mountain elk (Genius elaphus) suppressed the...

Prescribed fire in a ponderosa pine stand in the Blue Mountains, Oregon : relationships among post-fire scolytidae incidence, delayed tree mortality, snag decay dynamics, and woodpecker snag use

Creator:: Kangas, Michael
Abstract:: Delayed tree mortality is an unpredictable occurrence when prescribed burning is implemented. Fire scorched trees may die as the result of crown scorching, stem charring, root injury, bark beetle attack, or through a combination of these factors. This study examined ponderosa pine mortality and the incidence of two bark beetle...

Fire Refugia Function and Composition in Dry Mixed-Conifer Forests of Oregon’s Blue Mountains

Creator:: Downing, William M.
Abstract:: Contemporary fire effects are raising concerns about the resistance and resilience of dry mixed-conifer forests to large wildfires. Fire refugia – unburned or low-severity patches within fire perimeters – are understudied components of post-fire mosaics that may be key drivers of forest recovery following high-severity fire. Little is known about...

Thinning with prescribed fire and timber harvesting mechanization for fuels reduction and forest restoration

Creator:: Matzka, Peter J.
Abstract:: In the Blue Mountains of northeastern Oregon, prescribed fire and mechanical harvesting economics were investigated for fuels reduction and forest restoration. Using a cut-to-length harvesting system, three single-grip harvesters and three forwarders produced significantly different production rates. For the harvesters, significant variables that affected production rates were found to be:...

Impacts of ponderosa pine forest restoration treatments on the ectomycorrhizal fungal community and fine root biomass in the Blue Mountains of Oregon

Creator:: Smith, Jane E. (Jane Elizabeth)
Abstract:: Before the arrival of Euro-Americans, the inland Pacific Northwest was settled by native people whose frequent intentional burning of the landscape promoted open stands dominated by large fire-resistant ponderosa pine. Fire suppression for nearly a century, livestock grazing, and logging of the largest trees has resulted in forests characterized by...

Distribution and behavior of cattle grazing riparian pastures

Creator:: Wilson, Marie A. (Marie Annette)
Abstract:: One second GPS collars were deployed on cattle in three different pastures at three separate times during the year. In each riparian pasture the vegetative communities and stream bank edge were digitally mapped using low elevation aerial photographs and checked in the field for accuracy. A 5 m buffer zone...
