Habitat in the backyard – Part 2: Rock On! | MSU Extension: When building the rock pile, try to have a diversity of sizes of rocks available.� The pile can simple and placed on top of the ground, but the habitat can be improved if you dig a hole in the ground.� In the bottom of the hole, place large rocks (or cinder blocks, ceramic flower pots or old clay drainage tile).� Try to layer the rocks in a way to allow for different shapes and sizes of crevices that the animals can access.� Above the ground, use smaller rocks mixed in with bigger ones.� Brush and stumps can also be integrated into the pile.
