Piñon And Juniper Field Guide: Asking The Right Questions To Select Appropriate Management Actions, Robin J. Tausch, R. F. Miller, B. A. Roundy, J. C. Chambers Jan 2009

Piñon And Juniper Field Guide: Asking The Right Questions To Select Appropriate Management Actions, Robin J. Tausch, R. F. Miller, B. A. Roundy, J. C. Chambers

Reports

Piñon-juniper woodlands are an important vegetation type in the Great Basin. Old-growth and open shrub savanna woodlands have been present over much of the last several hundred years. Strong evidence indicates these woodlands have experienced significant tree infilling and major expansion in their distribution since the late 1800s by encroaching into surrounding landscapes once dominated by shrubs and herbaceous vegetation. Both infilling and expansion affects soil resources, plant community structure and composition, water and nutrient cycles, forage production, wildlife habitat, biodiversity, and fire patterns across the landscape. Another impact is the shift from historic fire regimes to larger and more …


Public Priorities For Rangeland Management: A Regional Survey Of Citizens In The Great Basin, Bruce Shindler, Ryan Gordon, Mark W. Brunson Apr 2007

Public Priorities For Rangeland Management: A Regional Survey Of Citizens In The Great Basin, Bruce Shindler, Ryan Gordon, Mark W. Brunson

Reports

Healthy sagebrush communities in the Great Basin are rapidly disappearing due to invasion of non-native plants, catastrophic wildfires, and encroachment of pinyon-juniper woodlands. Land management options, including the use of prescribed fire, mechanical thinning, and herbicides can reduce the potential for wildfire and restore healthy plant communities. Public acceptance of management actions is a critical component of developing and implementing successful long-term land management plans. This study examined citizens' opinions and perceptions about rangeland management in the Great Basin.


Western Juniper Field Guide: Asking The Right Questions To Select Appropriate Management Actions, Richard F. Miller, Jonathan D. Bates, T. J. Svejcar, Frederick B. Pierson, L. E. Eddleman Jan 2007

Western Juniper Field Guide: Asking The Right Questions To Select Appropriate Management Actions, Richard F. Miller, Jonathan D. Bates, T. J. Svejcar, Frederick B. Pierson, L. E. Eddleman

Reports

Strong evidence indicates that western juniper has significantly expanded its range since the late 1800s by encroaching into landscapes once dominated by shrubs and herbaceous vegetation (fig. 1). Woodland expansion affects soil resources, plant community structure and composition, water, nutrient and fire cycles, forage production, wildlife habitat, and biodiversity. Goals of juniper management include an attempt to restore ecosystem function and a more balanced plant community that includes shrubs, grasses, and forbs, and to increase ecosystem resilience to disturbances. Developing a management strategy can be a difficult task due to uncertainty about how vegetation, soils, hydrologic function, and wildlife will …


Comparing Citizens' And Managers' Concerns About Sagebrush Management And Restoration In The Great Basin, Mark W. Brunson, Jennifer Peterson Jan 2007

Comparing Citizens' And Managers' Concerns About Sagebrush Management And Restoration In The Great Basin, Mark W. Brunson, Jennifer Peterson

Reports

The Great Basin sagebrush steppe ecosystem is among the most imperiled in the U.S. Cheatgrass invasion, conifer encroachment, and catastrophic wildfires are considered to be primary catalysts of decline. Efforts are underway to restore and increase the resiliency of this damaged ecosystem through broad-scale applications of fuel reduction and restoration treatments involving mechanical removal, prescribed fire, and herbicide application. While research points to the potential benefits of these treatments, controversy and challenge often surface when treatments are proposed on public lands. Therefore it is critical for land managers to understand the views held by key stakeholder groups concerning management and …


Computer Simulation Of The Hydrologic And Salinity Flow Systems Within The Bear River Basin, Robert W. Hill, Eugene K. Israelsen, J. Paul Riley Jan 1973

Computer Simulation Of The Hydrologic And Salinity Flow Systems Within The Bear River Basin, Robert W. Hill, Eugene K. Israelsen, J. Paul Riley

Reports

Accompanying the increased use of water resources is an increases accumulation of chemical pollutants. Te prevent degradation of the water resources beyong useful limits, pollution inputs from additional uses must be quite accurately predicted prior to implementation of the new use. The model described in this report was formulated to provide the required predictive capability for the Bear River Basin. Modeling concepts of the hydrologic system are based upon the development of basin relationships describing the hydrologic processes which are linked together by the countinuity-of-mass principle. The salinity flow system is then linked to the hydrologic system based on the …
