Originally published in 1979, Geraldine Ellis Watson's ""Big Thicket Plant Ecology"" is now back in print. This updated edition explores the plant biology, ecology, geology, and environmental regions of the Big Thicket National Preserve. After decades of research on the Big Thicket, Watson concluded that the Big Thicket was unique for its biological diversity, due mainly to interactions of geology and climate. A visitor in the Big Thicket could look in four different directions from one spot and view scenes typical of the Appalachians, the Florida Everglades, a southwestern desert, or the pine barrens of the Carolinas. Watson covers the ecological and geological history of the Big Thicket and introduces its plant life, from longleaf pines and tupelo swamps to savannah wetlands and hardwood flats.
