What’s New

Professor Benton Taylor Named Fellow of the Ecological Society of America
Benton is an ecosystem ecologist working to understand how terrestrial ecosystems will respond to global change, and what the consequences will be for future carbon cycling. His work spans from tropical rainforests to the arctic tundra, focusing primarily on how plant-microbial partnerships impact ecosystem responses to rising carbon dioxide levels, warming, drought, severe weather, nutrient pollution and human land use.

Washington Street Gate Renewal
Starting Monday, March 31, Washington Street Gate and Blackwell Footpath in Bussey Brook Meadow will be temporarily closed to the public during the next phase of our Entrance Improvement Project. In the meantime, we suggest that visitors follow directional signage in the landscape and use the Forest Hills entrance along the Arborway when going to or from the Forest Hills MBTA station.
