Abstract
The red wolf Canis rufus is endemic to the southeastern United States and has been reduced to a single population occupying the Albemarle Peninsula in coastal North Carolina. To ensure species persistence and to meet conservation goals as outlined in the Red Wolf Recovery Plan (USFWS 1990, 2007, 2018a), it is important to conduct habitat suitability analyses to identify potential sites for future reintroductions. Problematically, such habitat suitability analyses are hindered by limited insight into how the red wolf once used habitat in landscapes that differ extensively from the currently occupied locality. Therefore, here we outline and parameterize a habitat suitability analysis framework for identifying and ranking potential reintroduction sites across the historic range of the species. A geographic information system approach was used to develop multiple habitat suitability models based on indices of landscape type (i.e., cropland, forest) and metrics based on distance from a point to nearest road-types and to human populations. A land-use index was created based on information on habitat suitability, preference, and use extracted from the literature. We then incorporated human population measures and distances to major roads to create a single model of ranked suitability throughout the study area. This model was further used to identify suitability of large (>1000km2) parcels of federally managed lands. Results indicate large areas of potentially suitable lands occurring in multiple National Forests situated across the historic range of the species. This approach to habitat suitability analysis development is customizable and can be applied to other species whose historic ranges cover a variety of habitat types, but data is lacking on specifics about how the species used these habitats across their range.
期刊介绍:
Journal of Fish and Wildlife Management encourages submission of original, high quality, English-language scientific papers on the practical application and integration of science to conservation and management of native North American fish, wildlife, plants and their habitats in the following categories: Articles, Notes, Surveys and Issues and Perspectives. Papers that do not relate directly to native North American fish, wildlife plants or their habitats may be considered if they highlight species that are closely related to, or conservation issues that are germane to, those in North America.
