Resilience and resistance in sagebrush ecosystems are associated with seasonal soil temperature and water availability

Creator:: Roundy, Bruce A., Chambers, Jeanne C., Pyke, David A., Miller, Richard F., Tausch, Robin J., Schupp, Eugene W., Rau, Ben, and Gruell, Trevor
Abstract:: Invasion and dominance of exotic grasses and increased fire frequency threaten native ecosystems worldwide. In the Great Basin region of the western United States, woody and herbaceous fuel treatments are implemented to decrease the effects of wildfire and increase sagebrush (Artemisia spp.) ecosystem resilience to disturbance and resistance to exotic...

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...

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...

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...

Resilience to Stress and Disturbance, and Resistance to Bromus tectorum L. Invasion in Cold Desert Shrublands of Western North America

Creator:: Chambers, Jeanne C., Bradley, Bethany A., Brown, Cynthia S., D'Antonio, Carla, Germino, Matthew J., Grace, James B., Hardegree, Stuart P., Miller, Richard F., and Pyke, David A.
Abstract:: Alien grass invasions in arid and semi-arid ecosystems are resulting in grass–fire cycles and ecosystem-level transformations that severely diminish ecosystem services. Our capacity to address the rapid and complex changes occurring in these ecosystems can be enhanced by developing an understanding of the environmental factors and ecosystem attributes that determine...

Spring, summer and fall use by cattle and big game on foothill rangelands

Creator:: Miller, Richard F.
Abstract:: The objectives of this study were to evaluate environmental factors influencing use of several plant communities by cattle, elk and deer; determine under story production by plant species and the amount utilized by cattle, elk and deer in certain plant communities; evaluate the interactions of range use between cattle, elk...

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...

Greater Sage-Grouse movements and habitat use during winter in central Oregon

Creator:: Bruce, Jennifer R., Robinson, W. Douglas, Petersen, Steven L., and Miller, Richard F.
Abstract:: Greater Sage-Grouse (Centrocercus urophasianus) depend on sagebrush habitat for food and cover during winter, yet few sage-grouse winter ecology studies have been conducted. During January and February 2007, we monitored 22 radio-collared sage-grouse (7 females and 15 males) in central Oregon to characterize winter habitat use and movement patterns. We...
