The study attempts to predict favorable habitat and population levels by using GIS and a logistic regression model based on regional road abundance. Road densities and prey densities were used to estimate the available potential habitat. The study area consisted of the northeastern portion of the United States from upstate New York to Maine. The model found an estimated >77,000 km2 of suitable habitat for wolves, with the ability to sustain a population of approximately 1,312 wolves. Habitat and wolf densities were also compared with those in the midwest. The paper also notes that wolf recovery is dependent on high levels of ungulate prey, which in turn have other negative effects on the ecosystem. The authors suggest that wolf restoration in the Northeast take advantage of experience elsewhere, especially the upper Midwest.
