Forests and Grasslands pdf par John P Rafferty

Between their verdant canopies and shaded floors, forests contain a multi-tiered ecosystem that supports an abundance of flora and fauna. Together with the grasses and vegetation in the grasslands to which they are frequently adjacent, forests make up 70 percent of the Earths land area and sustain the majority of its species. With careful detail and beautiful photographs, this volume journeys to the woodland and grassland areas of the planet and examines the distinctive features and wildlife of each as well as techniques in forestry and forest management that have helped these remarkable regions survive.
