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...

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...

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...

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,...

Short-Term Butterfly Response to Sagebrush Steppe Restoration Treatments

Creator:: McIver, James and Macke, Euell
Abstract:: As part of the Sagebrush Steppe Treatment Evaluation Project (SageSTEP), butterflies were surveyed pre-treatment and up to four years post-treatment at 16 widely distributed sagebrush steppe sites in the interior West. Butterfly populations and communities were analyzed in response to treatments (prescribed fire, mechanical, herbicide) designed to restore sagebrush steppe...

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...

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...

Can Imazapic and Seeding Be Applied Simultaneously to Rehabilitate Medusahead-Invaded Rangeland? Single vs. Multiple Entry

Creator:: Davies, K. W., Madsen, M. D., Nafus, A. M., Boyd, C. S., and Johnson, D. D.
Abstract:: It has recently been proposed that the cost of rehabilitating medusahead (Taeniatherum caput-medusae [L.] Nevski)-invaded rangelands may be reduced by concurrently seeding desired vegetation and applying the preemergent herbicide imazapic. However, the efficacy of this ‘‘single-entry’’ approach has been inconsistent, and it has not been compared to the multiple-entry approach...

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...

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...
