Stream Bugs as Biomonitors: A Guide to Pacific Northwest Macroinvertebrate Monitoring and Identification
By Jeff Adams with Mace Vaughan and Scott Hoffman Black, The Xerces Society
(The CD-ROM was designed for use with PC computers)

The CD-ROM uses 900 pages of text and over 5000 images to detail the entire process of freshwater macroinvertebrate monitoring in the Pacific Northwest – from identifying macroinvertebrates to interpreting data. A section on the sampling process leads you through 10 steps of developing and implementing a macroinvertebrate monitoring program, with detailed information on each step. The identification section provides a variety of resources, including lists of freshwater macroinvertebrates by ecoregion (for Oregon and Washington); information on introduced macroinvertebrates; practice for field identification; and detailed identification guides and descriptions of nearly 500 Pacific Northwest macroinvertebrates.

Other major sections of the CD-ROM include background on macroinvertebrate monitoring, data interpretation, and using macroinvertebrate data to conserve your watershed. Also included is a section on sampling macroinvertebrates for education, several simple games, short macroinvertebrate movie clips, an extensive resource section, and a glossary of selected macroinvertebrate monitoring terminology.
