U.S. Geological Survey Science for the Wyoming Landscape Conservation Initiative - 2013 Annual Report U.S. Geological Survey Science for the Wyoming Landscape Conservation Initiative - 2013 Annual Report
This is the sixth report produced by the U.S. Geological Survey (USGS) for the Wyoming Landscape Conservation Initiative (WLCI) to detail annual activities conducted by USGS for addressing specific management needs identified by WLCI partners. In FY2013, there were 25 ongoing and new projects conducted by the USGS. These projects fall into 8 major categories: (1) synthesizing and...

Wyoming Basin Rapid Ecoregional Assessment: Work Plan Wyoming Basin Rapid Ecoregional Assessment: Work Plan
The overall goal of the Rapid Ecoregional Assessments (REAs) being conducted for the Bureau of Land Management (BLM) is to provide information that supports regional planning and analysis for the management of ecological resources. The REA provides an assessment of baseline ecological conditions, an evaluation of current risks from drivers of ecosystem change, and a predictive capacity...

Ecological thresholds as a basis for defining management triggers for National Park Service vital signs: case studies for dryland ecosystems Ecological thresholds as a basis for defining management triggers for National Park Service vital signs: case studies for dryland ecosystems
Threshold concepts are used in research and management of ecological systems to describe and interpret abrupt and persistent reorganization of ecosystem properties (Walker and Meyers, 2004; Groffman and others, 2006). Abrupt change, referred to as a threshold crossing, and the progression of reorganization can be triggered by one or more interactive disturbances such as land-use...

Data resources for the Wyoming Landscape Conservation Initiative (WLCI) Integrated Assessment (IA) Data resources for the Wyoming Landscape Conservation Initiative (WLCI) Integrated Assessment (IA)
The data contained in this report were compiled, modified, and analyzed for the Wyoming Landscape Conservation Initiative (WLCI) Integrated Assessment (IA). The WLCI is a long-term science based effort to assess and enhance aquatic and terrestrial habitats at a landscape scale in southwest Wyoming while facilitating responsible energy development through local collaboration and...

Mapping surface disturbance of energy-related infrastructure in southwest Wyoming--An assessment of methods Mapping surface disturbance of energy-related infrastructure in southwest Wyoming--An assessment of methods
We evaluated how well three leading information-extraction software programs (eCognition, Feature Analyst, Feature Extraction) and manual hand digitization interpreted information from remotely sensed imagery of a visually complex gas field in Wyoming. Specifically, we compared how each mapped the area of and classified the disturbance features present on each of three remotely sensed...
