Abstract: This report describes a multi-scale watershed assessment procedure that can be used to evaluate existing ecological conditions as well as proposed changes. The approach employs indicators of ecosystem integrity that are assessed at the stream reach scale using existing spatial data as well as field observations. Ecological integrity scores can be calculated using those indicators at multiple scales, ranging from the reach to the entire watershed. Reach-level integrity scores are dependent in part on upstream and downstream conditions; therefore, the method accounts for offsite effects of proposed impacts or restoration actions by recognizing degradation or improvement to areas not directly within the project footprint. Case studies are presented illustrating typical applications of the approach, including baseline and alternative impact assessments, as well as restoration scenarios. NOTE: This file is large.
