MIDN and NCBN Forest Monitoring 2007-2025 Data Package
The Inventory and Monitoring (I&M) Division's Mid-Atlantic Network (MIDN) and Northeast Coastal and Barrier Network (NCBN) have identified forest vegetation, and several associated vital signs, as high priority for long-term monitoring. The MIDN and NCBN long-term forest monitoring protocol was adapted from methods developed by the U.S. Forest Service Forest Inventory and Analysis program and was developed in collaboration with other eastern forest I&M networks. The forest monitoring protocol assesses the status and trends in structure, function, and composition of forested ecosystems, along with the impacts of stressors such as white-tailed deer, invasive exotic plants, exotic pests and pathogens, and effects of acid deposition on forest soils. A set of Standard Operating Procedures are shared with the Northeast Temperate Network's forest vegetation monitoring protocol.
The current protocol has been designed to sample 392 plots in forested areas of MIDN and NCBN parks. Plot locations are randomly chosen from a 250-m grid developed for both networks using a spatially balanced design (generalized random-tessellation stratified). Each plot consists of a 20 x 20 m square where all stems with a diameter at breast height (dbh) ≥10 cm are identified, measured, tagged, marked, mapped, and their condition assessed. Stems with a dbh ≥1 cm are identified and measured in each of three microplots. Percent cover of shrubs ≥30 cm tall are also recorded in each of three microplots. Percent cover of all vascular plant species is estimated by species in eight 1 m2 quadrats. Number of tree seedlings by height class are also counted and assessed for presence or absence of deer browse in the 1 m2 quadrats. Coarse woody debris is measured along three 15 m transects. Data collected are used to inform management decisions affecting forested systems in MIDN and NCBN parks.

This data package contains a cumulative record of all forest monitoring data collected at National Park units in the Mid-Atlantic Network (MIDN) and Northeast Coastal and Barrier Network (NCBN) through the most recent field season and is organized into twenty-six (25) datasets:
