BLM-OR/WA, Watershed Assessment Model Development

The Aquatic and Riparian Monitoring Program (AREMP) assesses the effectiveness of cumulative land management action on watershed condition across multiple jurisdictions within the range of the Northern Spotted Owl. Watersheds are evaluated using upslope and riparian information derived from Geographic Information System (GIS) and remotes sensing data, as well as inchannel attributes measured as part of a field sampling program. The AREMP uses both a decision support model framework, as well as statistical methodologies, developed, refined, and implemented in cooperation with CESU Portland State University to estimate several parameters used to assess watershed condition. Approaches and methodologies are reevaluated between 5 year reporting intervals to improve our ability to track condition and trend of watersheds at multiple spatial scales.
