Community analysis of the Wyoming big sagebrush alliance and functional role of Wyoming big sagebrush

Creator:: Davies, Kirk W.
Abstract:: This study consisted of two research projects in the Wyoming big sagebrush (Artemisia tridentata ssp. wyomingensis (Beetle & A. Young) S.L. Welsh) alliance, the most extensive of the big sagebrush complex in the Intermountain West. In the first project, we intensively sampled 107 relatively undisturbed, late seral Wyoming big sagebrush...

Role of propagule pressure and priority effects on plant establishment during restoration of invaded shrub-steppe

Creator:: Schantz, Merilynn C.
Abstract:: Biological plant invasions are diminishing the ecological integrity and function of ecosystems worldwide. A primary example of this is in the Great Basin of the United States, where invasive annual grasses, like cheatgrass (Bromus tectorum L.) and medusahead (Taeniatherum caput-medusae L. Nevski), are dominating many sagebrush-steppe ecosystems. In these invaded...

Effects of plant community characteristics on insect abundance : implications for sage-grouse brood-rearing habitat

Creator:: Ersch, Erica A.
Abstract:: A causative factor in declining greater sage-grouse (Centrocercus urophasianus) populations is reduced annual recruitment due to poor habitat quality. Sage-grouse population decline is concurrent with a decline in the extent and quality of the sagebrush (Artemisia sp.) biome. However, current research has shown a positive relationship between sage-grouse brood and...

Shrub reestablishment following fire in the mountain big sagebrush (Artemisia tridentata Nutt. ssp. vaseyana (Rydb.) Beetle) alliance

Creator:: Ziegenhagen, Lori L.
Abstract:: Currently, the of lack information on shrub reestablishment following fire and the wide variability in rates of recovery have lead to uncertainty in using prescribed burning as a management tool in the mountain big sagebrush (Artemisia tridentata Nutt. ssp. vaseyana (Rydb.) Beetle) alliance. This study examined the recovery of shrub...

Long-term Fuel Succession in the Sagebrush-steppe

Creator:: Reis, Schyler Ainsworth
Abstract:: Historically fire has been the primary disturbance factor in the sagebrush-steppe. The settlement of the West by Euro-Americans, grazing by domestic livestock, and the concomitant spread of invasive species have altered the historical fire regime. Understanding the long-term vegetation structure and fuel succession of the various sagebrush-dominated communities of this...

Sugar application and nitrogen pools in Wyoming big sagebrush communities and exotic annual grasslands

Creator:: Witwicki, Dana L.
Abstract:: Within A rtemisia tridentata ssp. wyomingensis Nutt. (Wyoming big sagebrush) communities of the Great Basin, lands dominated by the exotic annual grass Bromus tectorum L. (cheatgrass) are increasing at an alarming rate. Carbon applications, which reduce plant-available soil N, have been suggested as a way to give native vegetation a...

Changes in protected and grazed sagebrush-grass in eastern Oregon, 1937 to 1974

Creator:: Sneva, Forrest, Rittenhouse, L. R. (Larry Ronald), 1940-, Tueller, P. T., Reece, P., and Oregon State University. Agricultural Experiment Station
Abstract:: Time was the most significant factor influencing brush and grass change inside and outside cattle exclosures over a 37-year period (1937-1974). The 10 exclosures (2 ha) represent the big and low sagebrush (A. tridentata and A. arbuscula) Qunchgrass vegetation of eastern Oregon and were established on the Squaw Butte Experiment...

Associations Between Crested Wheatgrass and Native Vegetation in Southeastern Oregon : An Investigation of Co-establishment, Environment, Seeding History, and Livestock management

Creator:: Nafus, Aleta M.
Abstract:: Crested wheatgrass (Agropyron cristatum [L] Gaertm), an introduced bunchgrass, has been seeded on over 5 million hectares of degraded rangeland in western North America because it establishes more readily than native bunchgrasses. Because crested wheatgrass stands are associated with native species displacement and low biological diversity, there is substantial interest...

Correspondence of soil properties and classification units with sagebrush communities in southeastern Oregon

Creator:: Lentz, Rodrick David
Abstract:: This research employed multivariate analytical techniques to statistically examine the relationship between individual soillandscape units (SLUs) in Southeastern Oregon and their associated sagebrush communities. The objective was to determine if soil properties between SLUs differed, describe the variation, and verify that these differences were reflected in the taxonomic class of...
