Mowing Wyoming Big Sagebrush Communities With Degraded Herbaceous Understories: Has a Threshold Been Crossed?

Creator:: Davies, Kirk W., Bates, Jonathan D., and Nafus, Aleta M.
Abstract:: Wyoming big sagebrush (Artemisia tridentata ssp. wyomingensis [Beetle & A. Young] S.L. Welsh) plant communities with degraded native herbaceous understories occupy vast expanses of the western United States. Restoring the native herbaceous understory in these communities is needed to provide higher-quality wildlife habitat, decrease the risk of exotic plant invasion,...

Understory Cover Responses to Piñon-Juniper Treatments Across Tree Dominance Gradients in the Great Basin

Creator:: Roundy, Bruce A., Miller, Richard F., Tausch, Robin J., Young, Kert, Hulet, April, Rau, Ben, Jessop, Brad, Chambers, Jeanne C., and Eggett, Dennis
Abstract:: Piñon (Pinus spp.) and juniper (Juniperus spp.) trees are reduced to restore native vegetation and avoid severe fires where they have expanded into sagebrush (Artemisia tridentata Nutt.) communities. However, what phase of tree infilling should treatments target to retain desirable understory cover and avoid weed dominance? Prescribed fire and tree...

Effects of Using Winter Grazing as a Fuel Treatment on Wyoming Big Sagebrush Plant Communities

Creator:: Davies, K. W., Nafus, A. M., Boyd, C. S., Hulet, A., and Bates, J. D.
Abstract:: More frequent wildfires and incidences of mega-fires have increased the pressure for fuel treatments in sagebrush (Artemisia) communities. Winter grazing has been one of many fuel treatments proposed for Wyoming big sagebrush (A. tridentata Nutt. subsp. wyomingensis Beetle and A. Young) communities. Though fire risk and severity can be reduced...

Of Grouse and Golden Eggs: Can Ecosystems Be Managed Within a Species-Based Regulatory Framework?

Creator:: Boyd, Chad S., Johnson, Dustin D., Kerby, Jay D., Svejcar, Tony J., and Davies, Kirk W.
Abstract:: Declining greater sage-grouse populations are causing concern for the future of this species across the western United States. Major ecosystem issues, including exotic annual grass invasion and conifer encroachment, threaten vast acreages of sagebrush rangeland and are primary threats to sage-grouse. We discuss types of problems facing sage-grouse habitat and...

Fuel Reduction, Seeding, and Vegetation in a Juniper Woodland

Creator:: Kerns, B. K. and Day, M. A.
Abstract:: Western juniper has increased in density and distribution in the interior Pacific Northwest since the late 1800s. Management goals for many juniper woodlands are now focused on reducing tree densities and promoting biodiversity, prompting the use of fuel reduction treatments. Fuel reduction often involves mechanical cutting and disturbances such as...

Assessing the Carbon Consequences of Western Juniper (Juniperus occidentalis) Encroachment Across Oregon, USA

Creator:: Campbell, John L., Kennedy, Robert E., Cohen, Warren B., and Miller, Richard F.
Abstract:: Our ability to assess the continental impacts of woody encroachment remains compromised by the paucity of studies quantifying regional encroachment rates. This knowledge gap is especially apparent when it comes to quantifying the impact of woody encroachment on large-scale carbon dynamics. In this study, we use a combination of aerial...

A Synopsis of Short-Term Response to Alternative Restoration Treatments in Sagebrush-Steppe: The SageSTEP Project

Creator:: McIver, James, Brunson, Mark, Bunting, Steve, Chambers, Jeanne, Doescher, Paul, Grace, James, Hulet, April, Johnson, Dale, Knick, Steve, Miller, Richard, Pellant, Mike, Pierson, Fred, Pyke, David, Rau, Benjamin, Rollins, Kim, Roundy, Bruce, Schupp, Eugene, Tausch, Robin, and Williams, Jason
Abstract:: The Sagebrush Steppe Treatment Evaluation Project (SageSTEP) is an integrated long-term study that evaluates ecological effects of alternative treatments designed to reduce woody fuels and to stimulate the herbaceous understory of sagebrush steppe communities of the Intermountain West. This synopsis summarizes results through 3 yr posttreatment. Woody vegetation reduction by...

Success of Seeding Native Compared with Introduced Perennial Vegetation for Revegetating Medusahead-Invaded Sagebrush Rangeland

Creator:: Davies, K. W., Boyd, C. S., Johnson, D. D., Nafus, A. M., and Madsen, M. D.
Abstract:: Millions of hectares of Wyoming big sagebrush (Artemisia tridentata Nutt. subsp. wyomingensis Beetle & Young) rangeland have been invaded by medusahead (Taeniatherum caput-medusae [L] Nevski), an exotic annual grass that degrades wildlife habitat, reduces forage production, and decreases biodiversity. Revegetation of medusahead-invaded sagebrush plant communities is necessary to restore ecosystem...

Restoring the Sagebrush Component in Crested Wheatgrass–Dominated Communities

Creator:: Davies, Kirk W., Boyd, Chad S., and Nafus, Aleta M.
Abstract:: Monotypic stands of crested wheatgrass (Agropyron cristatum [L] Gaertm. and Agropyron desertorum [Fisch.] Schult.), an introduced grass, occupy vast expanses of the sagebrush steppe. Efforts to improve habitat for sagebrush-associated wildlife by establishing a diverse community of native vegetation in crested wheatgrass stands have largely failed. Instead of concentrating on...

Response of Conifer-Encroached Shrublands in the Great Basin to Prescribed Fire and Mechanical Treatments

Creator:: Miller, Richard F., Ratchford, Jaime, Roundy, Bruce A., Tausch, Robin J., Hulet, April, and Chambers, Jeanne
Abstract:: In response to the recent expansion of piñon and juniper woodlands into sagebrush-steppe communities in the northern Great Basin region, numerous conifer-removal projects have been implemented, primarily to release understory vegetation at sites having a wide range of environmental conditions. Responses to these treatments have varied from successful restoration of...
