The overall objective of this work is to understand how changing climate and associated ecohydrological conditions will impact the distribution of sagebrush ecosystems over the next century. This study will provide valuable insight into the vulnerability of sagebrush ecosystems to changes in climate, climate variability, and disturbance regime. This work utilizes the best currently available downscaled climate data (Maurer) and builds upon recent published results. Products from this project will provide wildlife managers with the ability to categorize and prioritize areas based on their probability of being capable of supporting sagebrush ecosystems in the future, information that is crucial for upcoming listing...

FY2010In addition to regional Science and Traditional Ecological Knowledge projects that the Great Basin LCC (GBLCC) supports, GBLCC staff lend technical expertise to a range of projects and have contributed to important regional publications on a range of subjects. These publications range in type from textbooks, to management-oriented science and conservation plans, to scientific papers and have covered subjects like wind erosion following fire, soil microbiota response to drought, plant community resilience to invasive species, and alpine plant communities. In many cases these publications form foundations for scientifically-informed management strategies across the Great Basin.

In the desert Southwest, changes in species composition, abundance, and distribution that may occur with climate change have significant implications for management of natural resources. These changes include: the extirpation or introduction of species, losses of biodiversity, shifts in structure and function of ecosystems and the services they provide, changes in wildlife habitat, invasion of non-native species, and changes in fire regimes. For planning, mitigation, and adaption, land managers would be greatly aided by knowing, in advance, which plant species, functional types, and assemblages will change in response to climate change so that monitoring and mitigation measures can focus on those resources. FY2012In...

Soil water dynamic is a crucial factor for understanding water-limited, arid to semiarid ecosystems (Porporato et al. 2002, Loik et al. 2004, Lauenroth and Bradford 2006), which cover c. 30% of global land area (Peel et al. 2007). The spatial and temporal patterns of available water, i.e., the amount of soil water that is extractable by plants, is a major determinant of aboveground net primary production and plant functional composition (Noy-Meir 1973, Sala et al. 1988, Sala et al. 1997). Climatic conditions including precipitation, temperature and potential evapotranspiration (PET), which are frequently summarized in climate diagrams (Fig. 1a, Walter and Lieth 1967), explain general patterns of soil water availability...
