Northeast Temperate Network Forest Health Monitoring Report: 2006-2009 (Natural Resource Report NPS/NETN/NRR?2010/206)

In 2006 the Northeast Temperate Network (NETN) Inventory and Monitoring Program began implementing a long-term forest monitoring program to assess status and trends in forest composition, structure and function within ten national park units: Acadia National Park (ACAD), Marsh-Billings-Rockefeller National Historical Park (MABI), Minute Man National Historical Park (MIMA), Morristown National Historical Park (MORR), Roosevelt-Vanderbilt National Historic Sites (ROVA), Saint-Gaudens National Historic Site (SAGA), Saratoga National Historical Park (SARA), and Weir Farm National Historic Site (WEFA). Roosevelt- Vanderbilt National Historic Sites includes Eleanor Roosevelt National Historic Site (ELRO), Home of Franklin D. Roosevelt National Historic Site (HOFR), and Vanderbilt Mansion National Historic Site (VAMA). To date, NETN has established and sampled 344 permanent forest plots. In 2010, NETN will begin resampling plots in ACAD, MABI, MIMA, SAGA and SARA. This report summarizes metrics of ecological integrity for ACAD, ELRO/HOFR, MORR, VAMA, and WEFA, and examines forest composition and structure for all NETN parks sampled from 2006-2009.
