Specifications include, but are not limited to: Provide an evaluation of the contribution of natural foods, bait used in hunting, and other anthropogenic foods in the diets of Maine black bear;MDIFW has been monitoring black bears on three study areas in northern, central, and eastern Maine. These study areas differ in climate, vegetation, prey densities, human density, land use and road density. Although all three study areas are open to hunting in the fall with most bears having access to bait, bears on the central Maine study area also have access to other anthropogenic foods (e.g., crops, livestock, garbage, bird seed). Timber harvesting occurs on all three study areas providing foods associated with early successional northern forests. Northern study area (West of Ashland, Maine) Consistent snow pack from January – April Mix of spruce/fir forest and upland hardwoods (beech, maple, ash, aspen) Available potential foods: beechnuts, beaked hazelnut, raspberries, cherry, mountain ash berries, grass, forbes, and colonial insects Low deer densities, high moose densities Land use – forest products Human development –low (seasonal camps, dirt logging roads with public access) Central study area (Northwest of Bangor, Maine) Variable snow conditions Mix of forest, forested wetlands and bogs, and agriculture (corn, livestock) Expansive lowlands
