    A national study that was began in the Northeast in 1991. The objective is to monitor, assess, and report on long-term status and changes in forest health. This is done through assessing tree conditions, soil characteristics, lichens, and air quality on permanent plots established throughout the region.

  • National Woodland Owner Survey (NWOS)

    A nationwide study describing the demographic and attitudinal factors relating to private, forestland ownership, and how ownership issues relate to the socioeconomic situation in the U.S.

  • Forest Resource Use (FRS)

    A series of studies involving canvasses of primary wood-processing facilities, utilization studies at active harvesting operations, and residential fuelwood use that are designed to determine the impacts that the removals of forest products has on forest resources.

  • Pennsylvania Regeneration Study (PRS)

    A pilot study to assess regeneration adequacy using Forest Inventory and Analysis sample plot locations in Pennsylvania.

  • Landscape Dynamics (LD)

    Continuing studies on the extend to which increasing proximity of human development affects the biodiversity of native flora and fauna, hydrologic processes, and natural resource management of forest lands through fragmentation of the resource.

  • Delaware River Basin Study (CEMRI)

    An environmental monitoring study focusing on soil depletion, net primary productivity, water quality, and ecosystem dynamics in the Delaware River Basin that impacts 13,539 square miles in four northeastern states (New York, New Jersey, Pennsylvania, and Delaware).
