Peter D. Inskip 1982 <p>The habitat use information and Habitat Suitability Index (HSI) models presented in this document are intended for use in impact assessment and habitat management activities. Literature concerning the habitat requirements and preferences of northern pike is reviewed and then synthesized into HSI models, which are scaled to produce an index between 0 (unsuitable habitat) and 1 (optimal habitat). Assumptions used to transform habitat use information into these quantitative models are noted, and guidelines for model application are described. Other models found in the literature which may also be used to calculate an HSI are cited.</p> application/pdf en U.S. Fish and Wildlife Service Habitat Suitability Index Models: Northern pike reports
