Gravel pits and open mines – Areas are stripped of topsoil revealing exposed substrate such as sand. Found spottily throughout the county in glacial moraine deposits. Typical bird species include Tree Swallow, Bank Swallow and Killdeer.
Urban and Industrial – Includes all cities and towns. Typical bird species include Chimney Swift, European Starling and House Sparrow.
Regeneration/Young Forest – Includes areas of natural disturbance or logging, young forest 10-20 years old (recently cut/early successional forests will not be delineated on this map, due to the lack of compiled data). Typical bird species include Chestnut-sided Warbler, American Redstart, Black-and-white Warbler, Red-eyed Vireo, Rose-breasted Grosbeak, Wood Thrush and Veery.
Bare rock – Includes areas where rock outcrop communities typically are sparsely vegetated and have little soil development, with the chemical composition of the bedrock strongly influencing the species composition of the vegetation. The species that persist in the community must survive extreme drought and great fluctuations in the temperature of the ground surface. Only found in one location on the north shore of Mille Lacs Lake. Typical bird species for this habitat type include Whippoorwill and any species associated with nearby edge habitats.
Deciduous forest – On dry sites, the most common canopy dominants of Deciduous Forests are oak, aspen, and birch trees. Sugar Maple, Basswood, elm, and ash trees are common dominants on moist sites. Pines, especially White Pine, sometimes form a minor part of the forest canopy. Where the forest canopy is broken or interrupted (typically in oak-dominated forests) there is usually a dense layer of tall shrubs, including hazelnuts, dogwoods, prickly ashes, and cherries.
