Abstract:: A 1.5 ha mixed conifer stand in the Blue Mountains of Oregon was intensively examined to assess the impact of logging disturbance on soils and herbaceous vegetation. Sampling was conducted six years after much of the timber overstory was removed in a shelterwood cut and yarded by crawler tractor. A...

Creator:: Swanson, Sherman R.
Abstract:: Infiltration, soil erosion, nitrogen loss and soil profile characteristics were measured on 36 sites representing land occupied by Artemisia tridentata ssp. tridentate, wyomingensis, and vaseyana. Infiltration, soil erosion, and nitrogen loss were strongly correlated but highly variable. Soil loss, but not infiltration or nitrogen loss was significantly different between subspecies....

Creator:: Doescher, Paul Steven
Abstract:: This research assessed certain specific plant-soil and community interrelationships in eastern Oregon habitat types dominated by subspecies of Artemisia tridentata. The first evaluation described plant-induced soil chemical patterns for Artemisia tridentata plant communities of high perennial grass-low shrub and low perennial grass-high shrub composition. Soil concentrations of total nitrogen, organic...

Creator:: Dysart, Patricia L.
Abstract:: Vegetation diversity in the Wyoming big sagebrush/Thurber needlegrass (Artemisia tridentata Nutt. ssp. wyomingensis Beetle & Young/Achnatherum thurberianum (Piper) Barkworth. syn. Stipa thurberiana Piper) plant association was studied across a condition class gradient in southeastern Oregon. All observable vascular plant species were counted during 6 seasons and 2 years and diversity...
