The Harvard Forest’s facilities include labs for clean counter-top analysis, non-clean actives (e.g. soils), and ecophysiology, in addition to cold storage.

Measuring a variety of atmospheric data, the Harvard Forest maintains four research towers, collecting publicly-accessible data throughout the tree canopy of the Prospect Hill tract.

Renovated from a former garage building, Harvard Forest’s climate-controlled document Archives building includes a variety of materials, including original research data and notes, publications and theses, a map library, photographs, and much more.

Located roughly ¾ miles southeast of Harvard Forest’s main campus, the Harvard Farm is home to the new Forest and Biodiversity experiment, which examines how forest diversity and introduced pests & pathogens affect forest function.

The Harvard Forest conference facility includes several residential houses, offering overnight accommodations for visitors. Units are available for up to 50 people in singles, doubles and triple rooms, all a short walk to Fisher Museum.

Harvard Forest is powered in part by solar energy, and a super-efficient thermal biomass system heats the entire main campus. Wood harvested from road and trail maintenance is used for fuel.

Our Woods Crew maintains 32 miles of public hiking trails throughout Harvard Forest’s Prospect Hill and Tom Swamp tracts, both located in Petersham.
