Restoring and Managing Great Basin Ecosystems
Location: Range and Meadow Forage Management Research
Project Number: 5360-21630-001-00
Start Date: Sep 10, 2012
End Date: Sep 09, 2017
1) Develop practices and strategies for restoring perennial livestock forages on degraded and fire-prone Great Basin rangelands using combinations of grazing management, soil treatments, seed coatings, and traditional restoration techniques.
2) Develop decision-support tools to enhance livestock production and other ecosystem services in different sites, climate conditions, and management systems on northwestern rangelands.
The mission of the Burns unit is to provide the science for sound land and livestock management. This five-year plan builds on a rich history of research at this location, in some cases reaching back to the 1940's. The majority of the western U.S. is occupied by rangelands and the most efficient commodity production in the rangeland environment is grazing livestock. Sustainable management of western U.S. rangelands is facing threats of unprecedented scale from annual grass invasion, encroaching conifers, and an uncertain climate future. Simultaneously, the societal demand for a diversity of ecosystem services from these resources has increased dramatically in recent years. Producers and land managers in the western U.S. are faced with information gaps regarding plant community restoration and establishment of desired species, management of grazing livestock, and vegetation responses to management actions in spatially and temporally variable environments. Filling these information gaps is critical to maintaining the security of livestock forage across the western U.S.
During the next five years we will build on our prior research addressing issues critical to our understanding and management of sagebrush steppe rangeland. Our focus will be on 1) developing management practices and tools for restoring/rehabilitating sagebrush steppe following weed invasion and juniper expansion, and 2) developing management guidelines and assessment systems for conserving intact plant communities in a variable environment. Although the problem areas addressed by the Burns location stem from local and regional scale issues, our specific research questions and designs help to illuminate principles applicable to national and international issues and audiences through peer review research and synthesis publications. A focus of this research unit has been to provide tools that managers can use, including but not limited to non-technical research reports, information syntheses, field guides and decision trees.
Projected benefits of successfully completing and transferring this research are: 1) improved management of existing sagebrush steppe for a variety of uses including forage production and habitat for critical wildlife species, 2) increased probability of success for restoration/revegetation projects, 3) increased ability to determine the effects of management practices within complex landscapes, and 4) a better understanding of the role of climate and site factors in influencing site productivity and restoration/revegetation success.
