Evolution of Sagebrush Rangelands in the Western United States
In this article we develop a simulation model for estimating the economic efficiency of fuel treatments and apply it to two sagebrush ecosystems in the Great Basin of the western United States: Wyoming Sagebrush Steppe and Mountain Big Sagebrush. These two ecosystems face the two most prominent resource management concerns in sagebrush ecosystems relative to wildfire: annual grass invasion and ...
متن کاملRange-wide analysis of wildlife habitat: Implications for conservation
The range-wide habitat status of many endangered species is unclear. We evaluated the status and spatial distribution of the habitat of the endangered giant panda (Ailuropoda melanoleuca) across its entire geographic range (i.e., six mountain regions located in Sichuan, Shaanxi and Gansu provinces, China) by integrating field and remotely sensed data to develop a habitat distribution model. Res...
متن کاملUnderstanding and predicting habitat for wildlife conservation: the case of Canada lynx at the range periphery
Ecologists and managers are motivated to predict the distribution of animals across landscapes as well as understand the mechanisms giving rise to that distribution. Satisfying this motivation requires an integrated framework that characterizes multi-scale habitat use and selection, as well as builds predictive models such as resource selection functions. However, the assumption of constant hab...
متن کاملSoil carbon sequestration in United States rangelands
Rangelands are uncultivated lands that include grasslands, savannahs, steppes, shrub lands, deserts and tundra. The native vegetation on rangelands is predominantly grasses, forbs and shrubs (Kothmann, 1974). Rangelands cover 31 percent of the land surface area of the United States (Havstad et al., 2009), and up to half of the land surface area worldwide (Lund, 2007). Most land areas that are n...
