Intensive logging and two great fires stripped Zealand Valley of virtually all vegetation. The presence today of a luxuriant, hardwood forest is a fine example of nature's recuperative powers and forest succession. The dominant tree species are red maple, white birch, and beech. Red spruce and balsam fir are found at higher elevations and rocky sites. Many species of shrubs and plants common to the northern hardwood coniferous forest are found throughout the Zealand Valley.
Animal life includes black bear, moose, deer, snowshoe hare, and beaver.
A number of beaver dams and ponds are located along Zealand Trail. Dusk is the best time of day to observe beavers at work. The Hale Brook Trail begins at 1750 feet from a small parking area on the west side of the Zealand Road. The trail length is 2.3 miles of moderate grade. The trail ascends Mt. Hale through white birch forest with good views from the summit.
