Bird Populations Respond to Climate Change, Land Use and Winter Feeding

Rosemary Balfour completed her Masters of Liberal Arts degree at Harvard in June working with thesis advisors David Foster and Wayne Petersen of the Massachusetts Audubon Society. Rosemary's study utilized Christmas Bird Count data to examine the long-term trends in the abundance and composition of the bird populations that overwinter across the inland regions of Massachusetts. Her research concluded that

Land-use History Effect on Forest Ecosystems

We used stable N isotopes in tree rings and lake sediments to demonstrate that N availability in a northeastern forest has declined over the past 75 years, likely because of ecosystem recovery from Euro-American land use. Forest N availability has only recently returned to levels forecast from presettlement trajectories, rendering the trajectory of future forest

New Harvard Forest Publication: Plant Life History of Coastal Sandplain Grassland Taxa

Coastal sandplain grasslands of New England harbor a number of rare plant species, but few systematic management techniques have been developed to help foster or restore these critical habitats. Farnsworth (2007) applied a comparative, functional group approach to coastal sandplain grassland taxa in order to examine whether rare plant species share certain aspects of rarity and life history characters that
