Far above Buttermilk Falls in Ithaca sits a reservoir dam impounding Lake Treman. Hiking trails wend through the area, which for eight decades has slowly accumulated enough sediment to turn the lake into plodding marsh. Sometime in the next 30 years, it will completely fill and become a riparian marsh. Our students in the Restoration Ecology class led by Thomas Whitlow, associate professor in the Horticulture Section of the School of Integrative Plant Science, spent the fall semester examining Lake Treman's many components, and they worked with the New York State Department of Parks and Recreation to develop a plan for managing it.
