Animals and birds need places for shelter from predators and bad weather. These can be trees, shrubs, thickets or brush piles, which provide places for wildlife to hide. Dead trees (snags) provide habitat for a wide variety of species as they decay, serving as nesting sites, hiding places or food storage areas for birds, amphibians, reptiles, small mammals, and raptors. Bird houses, bat houses, and roosting boxes can be constructed to provide shelter for many species of wildlife.
Two of the following types of shelter must be provided to qualify for certification: dense shrubs or thicket, bramble patch, wooded area, evergreen trees, ground cover, brush or log pile, meadow or prairie, burrow, rock pile or wall, cave, water garden, pond, or roosting box.
