Maine has been identified as holding potential for the reintroduction of wolves. Due to the long ranges of wolves, it is beneficial to map potential corridors of movement. This project analyzes the best routes for movement from suitable habitats in New York to suitable habitats in Maine. It shows the paths likely to be taken by wolves, based on their affinity for mixed and coniferous forest and their avoidance of areas of high road density. These corridors are identified using least cost path analysis and take into account topography as well as forest and road densities.

“Conservation Lands” include both public and private lands that are devoted to the protection of wildlife and natural resources. “Listed Species” include federally and state endangered and threatened animals that are in danger of extermination in the state of Maine. The purpose of this study is to determine how well conservation lands are protecting the habitats of listed species. GAP data was used for 13 terrestrial vertebrate species indicating the presence or absence of suitable habitats. This data was compiled in GIS, generating a layer showing the number of listed species an area is suitable for. The areas that were suitable for at least one habitat were compared to answer three questions: (1) Is there is a difference between the presence and absence of listed species on protected lands and lands that are not protected? (2) Is there is a difference between the presence and absence of listed species on public lands managed by the state and the federal government and private land? (3) Is there is a difference between the presence and absence of listed species on lands protected under easements and lands that are protected fee simple? We found significant differences between all three categories. Conservation lands, private lands, and lands held under easement protect the habitat of listed species most effectively. We believe that this is due to the large number of private land trusts in the state of Maine and the effective management strategies of state lands.
