Lewis JC and Garrison RL. 1984. Habitat Suitability Index Models: American Black Duck (Wintering). Habitat Suitability Index Models. FWS OBS-82 10.68. United States Fish And Wildlife Service. Washington, DC
The habitat suitability index (HSI) models for American black duck are intended for use in impact assessment and management of winter habitat along the Atlantic coast. The models were developed from a review and synthesis of existing information and are scaled to produce indices of habitat suitability between 0 (unsuitable habitat) and 1 (optimal habitat) (U.S. Fish and Wildlife Service 1981). Assumptions used in developing the HSI models and guidelines for using models are described. These models are hypotheses of species-habitat relations. not statements of proven cause and effect. The models have been partially validated (Lewis et al. 1984).
