You can provide wildlife cover and denning
sites by piling large rocks, or crisscrossing railroad ties and planting
wild grape vines in among the pile. Locate such piles near shrubs and
brush. If you lawn lacks mature trees needed for natural next building,
secure nest boxes for songbirds and squirrels in the crooks of the trees
or on poles. If building your own nest boxes, follow these
specifications and place in the appropriate habitat for the bird or
mammal.
