Yield responses of invasive grasses to carbon doses

Creator:: Brunson, Jessi L.
Abstract:: The sagebrush steppe ecosystem of the northern Great Basin is severely degraded and continues to decline due in large part to the invasive, non-native annual grasses Bromus tectorum L. (cheatgrass) and Taeniatherum caput-medusae (L.) Nevski (medusahead). Restoration of invasive-dominated areas is difficult, but can be enhanced by adding a carbon...

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...

The effects of defoliation on Bromus tectorum seed production and growth

Creator:: Mayer, Kara Hempy
Abstract:: Cheatgrass (Bromus tectorum L.) is a widespread exotic weed in the Intermountain sagebrush steppe. An annual grass, it is highly prolific and very competitive with native perennial grass seedlings. A clipping experiment carried out at two cheatgrass-dominated sites (Lincoln Bench and Succor Creek) in eastern Oregon analyzed effects of defoliation...

Seed and seedling ecology of Artemisia tridentata in a restoration context

Creator:: Wijayratne, Upekala C.
Abstract:: The semi-arid sagebrush steppe ecosystem is one of the largest biomes in North America. The steppe provides critical habitat and forage for wildlife and is economically important to recreation and livestock industries. However, the ecosystem is threatened primarily due to several negative effects associated with expansion of the exotic annual...

Establishment tolerance of six native sagebrush steppe species to imazapic (PLATEAU®) herbicide implications for restoration and recovery

Creator:: Bekedam, Steven
Abstract:: Scientists and land managers realize that integrated weed management (IWM) strategies are needed to attain successful and lasting improvements of weed infested landscapes. At this time no broadly reliable and environmentally safe IWM strategy has been developed to control exotic annual grasses that dominate many ecosystems of the northern Great...

Litter decay processes and soil nitrogen availability in native and cheatgrass-dominated arid rangelands

Creator:: Harrison, Kristen S.
Abstract:: As large-scale restorations of degraded rangelands are initiated, land managers need to understand how decades of dominance by the invasive annual grass, cheatgrass (Bromus tectorum L.), have altered ecosystem processes. One way to assess such alterations is by observing differences in decay rates, since decomposition is determined by factors such...

Climate-growth relationships of western juniper and ponderosa pine at the pine-woodland ecotone in southern Oregon

Creator:: Knutson, Kevin C.
Abstract:: Pinyon-juniper woodlands throughout the western U.S. have expanded rapidly following European settlement during the late 19th century. In central and eastern Oregon, western juniper (Juniperus occidentalis var. occidentalis Hook.) encroachment has been previously documented in the sagebrush steppe and upper elevation aspen communities. While these vegetation changes and dynamics have...

Tackifier Type and Concentration have Varying Impacts on Growth of Dryland Mosses

Creator:: Blankenship, Wyatt D.
Abstract:: There is growing interest in using biocrusts (assemblages of cyanobacteria, lichens, mosses, and other taxa in various proportions covering the upper few millimeters of the soil surface) to assist in restoring ecosystem function and native plant communities in dryland ecosystems. Biocrusts can be transplanted and established using jute or thatch,...

Drivers of plant community dynamics in sagebrush steppe ecosystems : cattle grazing, heat and water stress

Creator:: Reisner, Michael D.
Abstract:: Sagebrush steppe ecosystems are one of the most widespread but endangered ecosystems in North America. A diverse array of human-related stressors has gradually compromised these ecosystems' resilience to disturbance and invasion by Bromus tectorum (cheatgrass). The role of the foundational shrub Artemisia as a driver of herbaceous community structure and...
