BLM Vulnerability to Climate Change

Summary

Ecotrust created the value-additions to the Watershed and Subwatershed hydrologic unit boundaries for our BLM Priorities tool project in 2013. More information can be found at: http://aquatics-blm.labs.ecotrust.org/ The Watershed and Subwatershed hydrologic unit boundaries provide a uniquely identified and uniform method of subdividing large drainage areas. The smaller sized 6th level sub-watersheds (up to 250,000 acres) are useful for numerous application programs supported by a variety of local, State, and Federal Agencies. This data set is intended to be used as a tool for water-resource management and planning activities, particularly for site-specific and localized studies requiring a level of detail provided by large-scale map [...]

Purpose

Climate change has the potential to alter freshwater habitat in many complex ways that are not yet fully understood. These changes are expected to greatly affect the health and distribution of fish species, particularly those adapted to cold water (U.S. Fish and Wildlife Service 2009; Williams, Haak, et al. 2009; Rieman, Isaak, et al. 2007; Mote et al. 2003). Because of this complexity, we chose an approach that was not species specific, but instead identified the vulnerability of each sub-basin to the effects of climate change that would most directly impact freshwater habitat: air temperature, flow regime, and wildfire. ​ This map represents the vulnerability of each watershed (HUC5; ranked relative to the other watersheds in Oregon and eastern Washington) to the effects of climate change that would most directly impact freshwater habitat: air temperature, flow regime, and wildfire.

Ecotrust created the value-additions to the Watershed and Subwatershed hydrologic unit boundaries for our BLM Priorities tool project in 2013. More information can be found at: http://aquatics-blm.labs.ecotrust.org/ Funding and support for the Watershed Boundary Dataset (WBD) were provided by the Natural Resources Conservation Service, the Environmental Protection Agency, and the United States Geological Survey. Representatives from the U.S. Geological Survey and Environmental Protection Agency contributed a substantial amount of time and salary towards quality review and updating of the dataset in order to meet the Federal Standards for Delineation of Hydrologic Unit Boundaries.
