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 into HSI models, which are scaled to produce an index between 0 (unsuitable habitat) and 1 (optimal habitat). The models are hypotheses of species-habitat relationships, and model users should recognize that the degree of veracity of the HSI model and assumptions will vary according to geographical area and the extent of the data base for individual variables. After clear study objectives have been set, the HSI model building techniques presented in U.S. Fish and Wildlife Service (1981)1 and the general guidelines for modifying HSI models and estimating model variables presented in Terrell et al. (1982)2 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. A statistically-derived model that is an alternative to using Suitability Indices to calculate an HSI is referenced in the text. Model reliability is likely to vary in different geographical areas and situations
