The State University of New York College of Environmental Science and Forestry (SUNY-ESF, or ESF) is an American, specialized, doctoral-granting institution based in Syracuse, New York. It is immediately adjacent to Syracuse University, within which it was founded, and with whom it maintains a special relationship. ESF is a part of the State University of New York (SUNY) system. ESF also operates facilities in the Adirondack Park (including the Ranger School in Wanakena), the Thousand Islands, elsewhere in central New York, and Costa Rica. The College's curricula focus on the understanding, management and sustainability of the environment and natural resources. ESF is considered by Peterson's to be the premier college in the U.S. for the study of environmental and natural sciences, design, engineering, policy and management of natural resources and the environment. The college has expanded its initial emphasis on forestry to include professional education in environmental science, landscape architecture, environmental studies, and engineering in addition to distinguished programs in the biological and physical sciences.
