The foresters of today, like Pinchot and Fernow in the past, plan and supervise the growth, protection, and utilization of trees. They make maps of forest areas, estimate the amount of standing timber and future growth, and manage timber sales. They also protect the trees from fire, harmful insects, and disease. Some foresters may be responsible for other duties, ranging from wildlife protection and watershed management to the development and supervision of camps, parks, and grazing lands. Others do research, provide information to forest owners and to the general public, and teach in colleges and universities.
