Restoration of Shrub Steppe Ecosystems
Science Center Objects
This research theme provides land managers information to help them make restoration decision at local and landscape scales.
Millions of acres of shrub-grassland ecosystems are in need of restoration in the western United States. For lands degraded by invasive annual grasses, we have been studying best management practices for restoring ecosystem function through using either native or introduced plant species. On lands with degraded herbaceous layers, we are attempting to restore grasses and forbs without destroying the shrubs. In addition, we are providing land managers with handbooks to use in making restoration decisions at local and landscape scales.

Date published: November 28, 2017Status: ActiveRestoration and Ecology of Arid Lands Team (FRESC)
The focus of our research is on the restoration and monitoring of the plants and soils of the Intermountain West. Our lab is part of the Snake River Field Station, but is located in Corvallis, Oregon. Research topics include fire rehabilitation effects and effectiveness, indicators of rangeland health, invasive species ecology, and restoration of shrub steppe ecosystems.

Biological soil crusts in ecological restoration: Emerging research and perspectives
Drylands encompass over 40% of terrestrial ecosystems and face significant anthropogenic degradation causing a loss of ecosystem integrity, services, and deterioration of social‐ecological systems. To combat this degradation, some dryland restoration efforts have focused on the use of biological soil crusts (biocrusts): complex communities of...
Antoninka, Anita; Faist, Akasha M.; Rodriguez-Caballero, Emilio; Young, Kristina E; Chaudhary, V Bala; Condon, Lea A.; Pyke, David A. Hydroseeding tackifiers and dryland moss restoration potential
Tackifiers are long‐chain carbon compounds used for soil stabilization and hydroseeding and could provide a vehicle for biological soil crust restoration. We examined the sensitivity of two dryland mosses, Bryum argenteum and Syntrichia ruralis, to three common tackifiers ‐ guar, psyllium, and polyacrylamide (PAM) ‐ at 0.5x, 1....
W. Dillon Blankenship; Condon, Lea A.; Pyke, David A. Transient population dynamics impede restoration and may promote ecosystem transformation after disturbance
The apparent failure of ecosystems to recover from increasingly widespread disturbance is a global concern. Despite growing focus on factors inhibiting resilience and restoration, we still know very little about how demographic and population processes influence recovery. Using inverse and forward demographic modelling of 531 post‐fire sagebrush...

Science framework for conservation and restoration of the sagebrush biome: Linking the Department of the Interior’s Integrated Rangeland Fire Management Strategy to long-term strategic conservation actions, Part 1. Science basis and applications
The Science Framework is intended to link the Department of the Interior’s Integrated Rangeland Fire Management Strategy with long-term strategic conservation actions in the sagebrush biome. The Science Framework provides a multiscale approach for prioritizing areas for management and determining effective management strategies within the...

Monitoring and adaptive management are fundamental concepts to rangeland management across land management agencies and embodied as best management practices for private landowners. Historically, rangeland monitoring was limited to determining impacts or maximizing the potential of specific land uses—typically grazing. Over the past several...
Karl, Jason W.; Herrick, Jeffrey E.; Pyke, David A. Using resilience and resistance concepts to manage persistent threats to sagebrush ecosystems and greater sage-grouse
Conservation of imperiled species often demands addressing a complex suite of threats that undermine species viability. Regulatory approaches, such as the US Endangered Species Act (1973), tend to focus on anthropogenic threats through adoption of policies and regulatory mechanisms. However, persistent ecosystem-based threats, such as invasive...

Restoration handbook for sagebrush steppe ecosystems with emphasis on greater sage-grouse habitat—Part 3. Site level restoration decisions
Sagebrush steppe ecosystems in the United States currently (2016) occur on only about one-half of their historical land area because of changes in land use, urban growth, and degradation of land, including invasions of non-native plants. The existence of many animal species depends on the existence of sagebrush steppe habitat. The greater sage-...

Using resilience and resistance concepts to manage threats to sagebrush ecosystems, Gunnison sage-grouse, and Greater sage-grouse in their eastern range: A strategic multi-scale approach
This report provides a strategic approach developed by a Western Association of Fish and Wildlife Agencies interagency working group for conservation of sagebrush ecosystems, Greater sage-grouse, and Gunnison sage-grouse. It uses information on (1) factors that influence sagebrush ecosystem resilience to disturbance and resistance to nonnative...

Filling the interspace—restoring arid land mosses: source populations, organic matter, and overwintering govern success
Biological soil crusts contribute to ecosystem functions and occupy space that could be available to invasive annual grasses. Given disturbances in the semiarid shrub steppe communities, we embarked on a set of studies to investigate restoration potential of mosses in sagebrush steppe ecosystems. We examined establishment and growth of two moss...

Handbook for sagebrush steppe restoration techniques can help sustain wildlife and western ecosystems
The sagebrush ecosystem in the western U.S is one of the largest ecosystems in North America, but it is also threatened from wildfire and invasive plants. “Restoration of these unique ecosystems will help sustain wildlife and livelihoods throughout the West," said David Pyke, the USGS ecologist and lead author of the final installment of a three-part sagebrush restoration handbook.
