Collins River and Ranger Creek have disappearing waterfalls, deep in the gorges, these streams drop over limestone ledges and flow into sinks. Logging has occurred in some sections of the gorges, but the forests are recovering rapidly. The forests of the area abound with oaks, hickories, maples, yellow poplars, hemlocks, pines and many other species of trees. Beneath the forest canopy is a vast array of shrubs, vines, wildflowers, mosses and ferns which rival the flora of the Great Smoky Mountains in number and variety. Wildflowers peak between April and mid-May.
Animal life is abundant at Savage Gulf.
Many species of birds, reptiles, and amphibians are found in the diverse habitats of the area. Squirrels, rabbits, woodchucks, and skunks can be seen. The skilled woodlorist can expect to find deer, bobcats, fox, grouse, and to hear the cry of the hawk and owl. Savage Gulf was designated in 1973 by the Tennessee State Legislature as a Class II Natural Scientific Area. Development in a Class II Natural Area is restricted to foot trails, foot bridges, and overlooks.
