Creator:: Tuitele-Lewis, Jamison
Abstract:: Two experiments were conducted on the invasive plant species Potentilla recta in northeastern Oregon to investigate both biological and ecological characteristics of the species. Growth analysis was conducted on the plant at three sites over a period of two years (2002 and 2003). Relative growth rate (RGR) was calculated for...

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...

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...

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...

Creator:: Morici, Kat
Abstract:: Wildland fires are an increasingly extensive, expensive, and frequent occurrence in dry forests of the western United States. Fuel reduction treatments are designed to reduce extreme fire behavior, promote resilient forest structure, and facilitate fire control efforts. Although there is widespread recognition that repeated treatments are needed to maintain desired...
