Mapping Pacific Northwest Riparian Areas: Measuring Current Condition And Prioritizing For Climate Change Adaptation
This project produced a base layer of riparian area and condition prioritized riparian areas likely to increase biological resilience to climate change. This project acted as a pilot for developing riparian area data layers for the WGA Crucial Habitat Assessment Tool.
Scope and Methods Energy exploration and development has progressed steadily over the past few years in the Muddy Creek subbasin, Carbon County, Wyoming. The area includes the Atlantic Rim and Creston energy fields. Gravel roads, drill pads, pipelines, buried powerlines, and both production and injection wells have been constructed in the watershed and more are being considered for permitting. Trace elements, such as selenium, arsenic, and copper, are known to occur in soils and water in the watershed, and in some areas at elevated levels. It is important to understand the geologic controls on the source, transport, and fate of these elements so that informed decisions can be made on how and where development should...
Decision-making and evaluation are facilitated by iteratively improving the overall knowledge base as new knowledge is acquired and products completed. The knowledge and products are then used to inform decisions made about habitat projects and other conservation activities and to inform evaluations of overall habitat project effectiveness in meeting WLCI goals.
Why Rangelands: The Central Valley of California, the surrounding foothills and the interior Coast Range include over 18 million acres of grassland. Most of this land is privately owned and managed for livestock production. Because grasslands are found in some of California’s fastest-growing counties, they are severely threatened by land conversion and development. In addition climate change stresses grasslands by potentially changing water availability and species distributions.Maintaining a ranching landscape can greatly support biodiversity conservation in the California Landscape Conservation Cooperative (LCC) region. In addition ranches generate multiple ecosystem services—defined as human benefits provided...
The foundation for USGS WLCI science and technical assistance: (1) identify the key drivers of change; (2) identify the condition and distribution of key wildlife species, habitat, and species’ habitat requirements; (3) evaluate wildlife and livestock responses to development; (4) identify the most effective and needed restoration, reclamation, and mitigation activities, as well as locations where conservation benefits may be maximized; (5) develop an integrated inventory and monitoring strategy; and (6) develop a data clearinghouse and information-management framework.
Work Accomplished in FY2009 and Findings Eight Landsat- and eight AWiFS-based habitat-component models were completed for the WLCI area, including estimates of cover percentage for shrub, herbs, litter, sagebrush, big 48 sagebrush, Wyoming sagebrush, and bare ground, and for shrub height. According to an independent accuracy assessment, primary root mean square error (RMSE) values for habitat components based on QuickBird (2.4-m resolution) ranged from 4.90 to 10.16; those based on Landsat (30-m resolution) ranged from 6.04 to 15.85; and those based on AWiFS (56-m resolution) ranged from 6.97 to 16.14. The models improved the state-wide characterization of categorical landcover classes by 8 percent over the National...
