The Hopkins Memorial Forest (HMF) is a 2600 acre (1040 ha) reserve in Massachusetts, New York and Vermont managed by the Williams College Center for Environmental Studies (CES) to facilitate and research and undergraduate teaching activities while preserving and monitoring forest resources, particularly through long-term ecological research. We strongly encourage disciplinary and interdisciplinary teaching, scholarly activity, and experimental research in the Forest. Results of HMF research are available through this web site. Low-impact recreational activities that foster an understanding and enjoyment of the forest environment are encouraged.
