dc.description.abstractThe US Fish and Wildlife Service's Habitat Evaluation Procedures (HEP) are widely used to assess the impacts of major water resource projects. These procedures provide a flexible tool that is also valuable when study objectives are limited or when lower resolution is desired. This report describes various options that can be used to tailor HEP to a particular application and level of effort desired by the user. Several techniques improve efficiency without sacrificing reliability; others reduce the resolution of the analysis, and their use depends upon the objectives of the study. The amount of effort involved in a habitat evaluation can be reduced by (a.) using only those portions of the HEP process that are appropriate to the application and (b.) simplifying the process, particularly those steps that affect the intensity of sampling. Options discussed in this report include focusing on important cover types, choosing evaluation species that have simple models, using community models, modifying models to eliminate variables or reduce resolution, tailoring· sampling effort to the shape of suitability index curves, and using portable data collectors.en_US
