PREFACEThis document is part of the Habitat Suitability Index (HSI) Model Series(FWS/OBS-82/10), which provides habitat information useful for impact assessmentand habitat management. Several types of habitat information areprovided. The Habitat Use Information Section is largely constrained to thosedata that can be used to derive quantitative relationships between key environmentalvariables and habitat suitability. The habitat use information providesthe foundation for HSI models that follow. In addition, this same informationmay be useful in the development of bther models more appropriate to specificassessment or evaluation needs. .The HSI Model Section documents a habitat model and information pertinentto its application. The model synthesizes the habitat use information into aframework appropriate for field application and is scaled to produce an indexvalue between 0.0 (unsuitable habitat) and 1.0 (optimum habitat). The applicationinformation includes descriptions of the geographic ranges and seasonalapplication of the model, its current verification status, and a listing ofmodel variables with recommended measurement techniques for each variable.In essence, the model presented herein is a hypothesis of species-habitatrelationships and not a statement of proven cause and effect relationships.Results of model performance tests, when avail abl e, are referenced. However,models that have demonstrated reliability in specific situations may proveunreliable in others. For this reason, feedback is encouraged from users ofthis model concerning improvements and other suggestions that may increase theutility and effectiveness of this habitat-based approach to fish and wildlifeplanning.
