“…We illustrate these steps with an example for Greater Sage‐grouse ( Centrocercus urophasianus , hereafter referred to as Sage‐grouse), one of the Great Basin's prominent bird species. Sage‐grouse have experienced range‐wide contractions in habitats and populations across western North America, including large areas in the Great Basin (Schroeder et al 1999; Rowland 2004). Populations have been extirpated by human activities in nearly 50% of its range (Schroeder et al 2004).…”

“…Sage‐grouse cannot persist without large areas of sagebrush and the associated understory of native grasses and forbs (Schroeder et al 1999). This stringent requirement for large areas of intact, native sagebrush communities provides a useful starting point for landscape planning and management (Wisdom et al 2005 a , 2005 b ).…”

“…All sagebrush community types typically serve as habitats for Sage‐grouse (Schroeder et al 1999; Rowland et al 2005). Because cheatgrass invasion and woodland expansion are the most widespread threats to persistence of these types (Suring et al 2005 b ; Wisdom et al 2005 b ; Miller et al 2008; Miller et al in press), we identified these two undesired disturbance processes for our example.…”

Native shrublands dominate the Great Basin of western of North America, and most of these communities are at moderate or high risk of loss from non-native grass invasion and woodland expansion. Landscape-scale management based on differences in ecological resistance and resilience of shrublands can reduce these risks. We demonstrate this approach with an example that focuses on maintenance of sagebrush (Artemisia spp.) habitats for Greater Sage-grouse (Centrocercus urophasianus), a bird species threatened by habitat loss. The approach involves five steps: (1) identify the undesired disturbance processes affecting each shrubland community type; (2) characterize the resistance and resilience of each shrubland type in relation to the undesired processes; (3) assess potential losses of shrublands based on their resistance, resilience, and associated risk; (4) use knowledge from these steps to design a landscape strategy to mitigate the risk of shrubland loss; and (5) implement the strategy with a comprehensive set of active and passive management prescriptions. Results indicate that large areas of the Great Basin currently provide Sage-grouse habitats, but many areas of sagebrush with low resistance and resilience may be lost to continued woodland expansion or invasion by non-native annual grasses. Preventing these losses will require landscape strategies that prioritize management areas based on efficient use of limited resources to maintain the largest shrubland areas over time. Landscape-scale approaches, based on concepts of resistance and resilience, provide an essential framework for successful management of arid and semiarid shrublands and their native species.

Wyoming big Sagebrush occupies warmer, more xeric, and lower elevation sites that are highly susceptible to Cheatgrass invasion, compared to relatively colder, more mesic, and higher elevation sites occupied by Mountain big sagebrush (West & Young 2000; Miller & Eddleman 2001; Connelly et al 2004, unpublished report).…”

The ecological integrity of Sagebrush (Artemisia spp.) ecosystems in the Intermountain West (U.S.A.) has been diminished by synergistic relationships among human activities, spread of invasive plants, and altered disturbance regimes. An aggressive effort to restore Sagebrush habitats is necessary if we are to stabilize or improve current habitat trajectories and reverse declining population trends of dependent wildlife. Existing economic resources, technical impediments, and logistic difficulties limit our efforts to a fraction of the extensive area undergoing fragmentation, degradation, and loss. We prioritized landscapes for restoring Sagebrush habitats within the intermountain western region of the United States using geographic information system (GIS) modeling techniques to identify areas meeting a set of conditions based on (1) optimum abiotic and biotic conditions favorable for revegetation of Sagebrush; (2) potential to increase connectivity of Sagebrush habitats in the landscape to benefit wildlife; (3) location of population strongholds for Greater Sage-Grouse (Centrocercus urophasianus, a species of conservation concern); and (4) potential impediments to successful restoration created by Cheatgrass (Bromus tectorum, an invasive exotic annual grass). Approximately 5.8 million ha in southwestern Idaho, northern Nevada, and eastern Oregon met our criteria for restoring Wyoming big sagebrush (Artemisia tridentata ssp. wyomingensis) and 5.1 million ha had high priority for restoring Mountain big sagebrush (A. tridentata ssp. vaseyana).Our results represent an integral component in a hierarchical framework after which site-specific locations for treatments can be focused within high-priority areas. Using this approach, long-term restoration strategies can be implemented that combine local-scale treatments and objectives with large-scale ecological processes and priorities.

“…Sagebrush is a woody, coarse, and multibranched shrub species (Beetle and Johnson , Rosentreter ). Sagebrush shrubs used for nesting by sage‐grouse typically have greater branching densities with more obstructing vegetation cover and have 1 or 2 openings in the shrub to permit the females to escape (Schroeder et al ). These characteristics of the “nest shrub” create a natural hair‐snare because hair often gets snagged on the woody branches of the plant when a predator crawls into the shrub to consume the eggs (Fig.…”

Despite a multitude of studies on sage-grouse (Centrocercus spp.), there is still sparse information on the predator communities that influence sage-grouse productivity and how these predator communities may change when sagebrush habitats are altered by human activities. As a proof-of-concept, we used mammalian hairs collected at depredated greater sage-grouse (C. urophasianus) nests and mitochondrial DNA sequencing to identify mammalian species that deposited the hairs at the depredated nests. We monitored nests of radiomarked female greater sage-grouse in an oil and gas development area in the Powder River Basin, Wyoming, USA, from 2009 to 2011. We collected mammalian hair samples from 56 depredated nests. We detected 5 species: American badger (Taxidea taxus), bobcat (Lynx rufus), coyote (Canis latrans), red fox (Vulpes vulpes), and striped skunk (Mephitis mephitis). Red fox and striped skunk are considered exotic predators-species outside of their historical range-in our study area and represented 20% of our detections. This method could be improved by gathering and analyzing various types of DNA sources including predator saliva from egg shell fragments, predator scat, and even feathers left by avian predators. Our results suggest that this method has merit as a noninvasive tool to better understand the community of mammalian nest predators present within large study areas, and role of exotic predators in sagebrush habitats.
