Habitat Suitability Index Models and Instream Flow Suitability Curves: Arctic Grayling Riverine Populations

Hubert WA, Helzner RS, Lee LA, Nelson PC. 1985. Habitat Suitability Index Models and Instream Flow Suitability Curves: Arctic Grayling Riverine Populations. Habitat Suitability Index Models. Biological Report 82 (10.110). United States Fish And Wildlife Service. Washington, DC

The Habitat Suitability Index (HSI) models presented in this publication aid in identifying important habitat variables. Facts, ideas, and concepts obtained from the research literature and expert reviews are synthesized and presented in a format that can be used for impact assessment. Users should recognize that the models are hypotheses of species-habitat relationships, and that the applicability of the HSI model, SI graphs, and assumptions will vary according to geographical area and the extent of the data base for individual variables. The HSI model building techniques published by the U.S. Fish and Wildlife Service (1981), and the general guidelines for modifying HSI models (Terrell et al. 1982) and estimating model variables (Hamilton and Bergersen 1984) may be useful for simplifying and applying the models to specific impact assessment problems. Simplified models should be tested with independent data sets, if possible. Model reliability is likely to vary in different geographical areas and situations. The U.S. Fish and Wildlife Service encourages users to provide comments, suggestions, and test results that may help us increase the utility and effectiveness of this habitat-based approach to impact assessment. The INSTREAM FLOW INCREMENTAL METHODOLOGY section of the report was written by P. Nelson. The remainder of the report was written by W. Hubert, R. Helzner, and L. Lee.
