Habitat Suitability Index Models: White-tailed deer in the Gulf of Mexico and South Atlantic Coastal Plains
A review and synthesis of existing information were used to develop a Habitat Suitability Index (HSI) model for the white-tailed deer (Odocoileus virginianus). The model consolidates habitat use information into a framework appropriate for field application, and is scaled to produce an index between 0.0 (unsuitable habitat) to 1.0 (optimum habitat). HSI models are designed to be used with Habitat Evaluation Procedures previously developed by the U.S. Fish and Wildlife Service.
Habitat Suitability Index Models: Red-winged blackbird
A review and synthesis of existing information were used to develop a Habitat Suitability Index (HSI) model for the red-winged blackbird (Agelaius phoeniceus L.). The model consolidates habitat use information into a framework appropriate for field application, and is scaled to produce an index between 0.0 (unsuitable habitat) to 1.0 (optimum habitat). HSI models are designed to be used with Habitat Evaluation Procedures previously developed by the U.S. Fish and Wildlife Service.
Habitat Suitability Index Models: Great blue heron
The great blue heron is the largest, most widely distributed, and best known of the American herons (Henny 1972). Great blue herons occur in a variety of habitats from freshwater lakes and rivers to brackish marshes, lagoons, mangrove areas, and coastal wetlands (Spendelow and Patton in prep.).
Habitat Suitability Index Models: Western grebe
The western grebe (Aechmophorus occi denta 1is) "breeds from southeastern Alaska, south-central British Columbia, central Alberta, central Saskatchewan and southwestern Manitoba south to southern Californi a, north-central Utah, southwestern Colorado, southwest~rn and northeastern New Mexico, western Nebraska, northwestern Iowa, and western Minnesota; and locally in Mexico from Chihuahua and Durango south to northern Guerrero, Puebla and San Luis Potosi" (American Ornithologists' Union 1983:10).
Habitat Suitability Index Models: The Arizona guild and layers of habitat models
This document is part of the Habitat Suitability Index Models Series, which provides habitat information useful for impact assessment and habitat management. Both of the models described in this report are based on the significant association of Wildlife species with vegetation structure. The models compare the structure in the study area with the vegetation structure that could potentially occur in thtat study area following land use changes or disturbance. These models provide a low resolution assessment of habitat structure relevant early in the land-use planning process.
Habitat Suitability Index Models: Brewer's sparrow
This document is part of the Habitat Suitability Index (HSI) model series, which provides habitat information useful for impact assessment and habitat management for the Brewer's sparrow (Spizella breweri). Several types of habitat information are provided. A Habitat Use Information Section can be used to drive quantitative relationships between key environmental variables and habitat suitability. The HSI Model Section documents a habitat model and information pertinent to its application. The model synthesizes the habitat use information into a framework appropriate for field application and is scaled to produce an index value between 0.0 (unsuitable habitat) to 1.0 (optimum habitat).
Wildlife guilds in Arizona desert habitats
This report summarizes information produced from Interagency Agreement No. AA-851-IA1-27 between the Bureau of Land Management (BLM), USDI, and the Fish and Wildlife Service (FWS), USDI. The contract was instrumental in the final development of wildlife guilds for the Hualapai-Aquarius planning area of the BLM in westcentral Arizona, reported herein. The Arizona study area was selected for the application of the guilding technology because a thorough assessment of the floral and faunal resources had recently occurred in conjunction with the development of a grazing Environmental Impact Statement (EIS). Thus, the association of wildlife species with habitat type was well known, which aided in the compilation of the data base necessary for the development of guilds. Some data were also available that described the vegetative structure of habitats. This was useful in the development of a model that evaluated the quality of habitat on the basis of the diversity of cover in those habitats (Short 1982).
Development and use of a habitat gradient model to evaluate wildlife habitat
Ecologists and wildlife managers are increasingly confronted with the problems of predicting the value of surface cover as wildlife habitat and developing management alternatives to offset wildlife values lost because of land-use change. These problems have become urgent and more acute because of increased demand for products from the land and diminished fiscal and manpower resources for obtaining meaningful environmental information for the decision maker. This paper describes a relatively rapid, simple, and quantitative process for evaluating the quality of an area as wildlife habitat.
