The West Bloomfield Trail Network, a former railroad corridor, stretches 4.25 miles through West Bloomfield, Orchard Lake, Keego Harbor, and Sylvan Lake. The West Bloomfield Parks and Recreation Commission bought it from the Grand Trunk Western Railroad in 1988 and 1989. Along this crushed limestone path, wildlife thrives in the linear edge zone where the trail buffers fields and woods. Garter snakes and northern water snakes sun themselves just off the path, while indigo buntings and American goldfinch add color and song to the shrubs. Leopard frogs, a threatened species identified by round dark spots and a white stripe on the lip, live in meadows and marshes and are most often found in wet grasses during summer, but pollution, development, lawn mowers, habitat destruction, and natural predators such as raccoons and snakes reduce their numbers. Red-tailed hawks perch watchfully for rabbits and mice, and turkey vultures with six-foot wingspans circle above road crossings on hot summer afternoons. Eastern coyotes, shy and resourceful predators with yellow eyes, pointed ears, and tails that hang down, hunt rodents and other small prey, pose no threat to humans, and likely have used the trail at one time or another.
