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...

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...

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...

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...

Knapweed Hay as a Nutritional Supplement for Beef Cows Fed Low-Quality Forage

Creator:: Bohnert, David W., Sheley, Roger L., Falck, Stephanie J., and Nyman, Arthur A.
Abstract:: Advancing our ability to use invasive plants for producing commodities is central to the agricultural industry. Our objective was to evaluate Russian knapweed (Acroptilon repens [L.] DC.) as a winter feed supplement for ruminant livestock. In Experiment 1, we utilized three ruminally cannulated steers in a completely randomized design to...

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

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...

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...

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...

Simulating Current Successional Trajectories in Sagebrush Ecosystems With Multiple Disturbances Using a State-and-Transition Modeling Framework

Creator:: Evers, Louisa B., Miller, Richard F., Doescher, Paul S., Hemstrom, Miles, and Neilson, Ronald P.
Abstract:: Disturbances and their interactions play major roles in sagebrush (Artemisia spp. L.) community dynamics. Although impacts of some disturbances, most notably fire, have been quantified at the landscape level, some have been ignored and rarely are interactions between disturbances evaluated. We developed conceptual state-and-transition models for each of two broad...

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...
