Long Term Ecological Research Program

The Harvard Forest Long Term Ecological Research (LTER) program is part of a national network of long-term ecological research sites. Within this framework we examine ecological dynamics in the New England region resulting from natural disturbances, environmental change, and human impacts. Emphasis is on processes including:

  • wind and fireLTER National Office Logo
  • past climate change
  • land-use and land cover dynamics
  • atmospheric pollution, especially nitrogen deposition and ozone
  • projected increases in global temperature
  • land management, land policy and conservation

An interdisciplinary group of PI scientists, post-doctoral fellows, and graduate students from many parts of Harvard and other institutions use three complementary approaches to long-term study:

  • historical studies of past conditions and dynamics
  • intensive measurements of current structure and function
  • measurements of integrated ecosystem response to experimental manipulations under relatively controlled conditions

Long-term studies span a broad range of spatial and temporal scales and seek to:
