In 1962, the state's surface strip-mine reclamation law came into effect. The most common method of reclamation in the 1930s was tree planting, but this was discouraging as the trees brought no quick economic return. A mature hardwood timber consisting of mostly white oak and hickory on the west edge of Pyramid SRA was not mined. Several stands of conifers were planted years ago, and there is a timber cover of cottonwood, box elder and sycamore trees, with oak and hickory trees increasing in number.
Many species of wildlife may be found in on the Pyramid site, including songbirds, deer, squirrels, beavers, rabbits, turkeys, bobcats, raccoons, opossums, coyotes, weasels, minks, woodchucks and waterfowl.
