Resilience and Resistance of Sagebrush Ecosystems: Implications for State and Transition Models and Management Treatments

Creator:: Chambers, Jeanne C., Miller, Richard F., Board, David I., Pyke, David A., Roundy, Bruce A., Grace, James B., Schupp, Eugene W., and Tausch, Robin J.
Abstract:: In sagebrush ecosystems invasion of annual exotics and expansion of piñon (Pinus monophylla Torr. and Frem.) and juniper (Juniperus occidentalis Hook., J. osteosperma [Torr.] Little) are altering fire regimes and resulting in large-scale ecosystem transformations. Management treatments aim to increase resilience to disturbance and enhance resistance to invasive species by...

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...

Large-Scale Downy Brome Treatments Alter Plant-Soil Relationships and Promote Perennial Grasses in Salt Desert Shrublands

Creator:: Schantz, Merilynn C., Monaco, Thomas A., Call, Christopher A., and Sheley, R. L.
Abstract:: Because invasive annual grasses can strongly influence soil resource availability and disturbance regimes to favor their own persistence, there is a great need to understand the interrelationships among invasive plant abundance, resource availability, and desirable species prominence. These interrelationships were studied in two salt desert sites where the local abundance...

Abundances of Coplanted Native Bunchgrasses and Crested Wheatgrass after 13 Years

Creator:: Nafus, Aleta M., Svejcar, Tony J., Ganskopp, David C., and Davies, Kirk W.
Abstract:: Crested wheatgrass (Agropyron cristatum [L] Gaertm) has been seeded on more than 5 million hectares in western North America because it establishes more readily than native bunchgrasses. Currently, there is substantial interest in reestablishing native species in sagebrush steppe, but efforts to reintroduce native grasses into crested wheatgrass stands have...

Piñon-Juniper Reduction Increases Soil Water Availability of the Resource Growth Pool

Creator:: Roundy, Bruce A., Young, Kert, Cline, Nathan, Hulet, April, Miller, Richard F., Tausch, Robin J., Chambers, Jeanne C., and Rau, Ben
Abstract:: Managers reduce piñon (Pinus spp.) and juniper (Juniperus spp.) trees that are encroaching on sagebrush (Artemisia spp.) communities to lower fuel loads and increase cover of desirable understory species. All plant species in these communities depend on soil water held at >-1.5 MPa matric potential in the upper 0.3 m...

Soil Resources Influence Vegetation and Response to Fire and Fire-Surrogate Treatments in Sagebrush-Steppe Ecosystems

Creator:: Rau, Benjamin M., Chambers, Jeanne C., Pyke, David A., Roundy, Bruce A., Schupp, Eugene W., Doescher, Paul, and Caldwell, Todd G.
Abstract:: Current paradigm suggests that spatial and temporal competition for resources limit an exotic invader, cheatgrass (Bromus tectorum L.), which once established, alters fire regimes and can result in annual grass dominance in sagebrush steppe. Prescribed fire and fire surrogate treatments (mowing, tebuthiuron, and imazapic) are used to reduce woody fuels...

Region-Wide Ecological Responses of Arid Wyoming Big Sagebrush Communities to Fuel Treatments

Creator:: Pyke, David A., Shaff, Scott E., Lindgren, Andrew I., Schupp, Eugene W., Doescher, Paul S., Chambers, Jeanne C., Burnham, Jeffrey S., and Huso, Manuela M.
Abstract:: If arid sagebrush ecosystems lack resilience to disturbances or resistance to annual invasives, then alternative successional states dominated by annual invasives, especially cheatgrass (Bromus tectorum L.), are likely after fuel treatments. We identified six Wyoming big sagebrush (Artemisia tridentata ssp. wyomingensis Beetle & Young) locations (152–381 mm precipitation) that we...

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...

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,...

Are Early Summer Wildfires an Opportunity to Revegetate Exotic Annual Grass–Invaded Plant Communities?

Creator:: Davies, Kirk W., Nafus, Aleta M., and Johnson, Dustin D.
Abstract:: Medusahead (Taeniatherum caput-medusae [L.] Nevski) is an exotic annual grass invading western rangelands. Successful revegetation of invaded-plant communities can be prohibitively expensive because it often requires iterative applications of integrated control and revegetation treatments. Prescribed burning has been used to control medusahead and prepare seedbeds for revegetation, but burning has...
