Battlefield at Gettysburg National Military Park.


Located in Adams County, south central Pennsylvania, the small town of Gettysburg, Pennsylvania was the site of the largest Civil War battle ever waged in the Western Hemisphere. The Gettysburg National Military Park is one of ten parks in the Mid-Atlantic Network which is part of a nation-wide effort of the National Park Service to generate scientifically sound information on the changing conditions of park ecosystems. In addition to the natural resource management activities performed by park staff, our scientists monitor the status and long-term trends of natural resources at the park. Each year, with the help of park staff and volunteers, we collect information for the monitoring programs listed below. Back at the office we analyze the data and share the information with park managers to help them better understand how to best preserve park ecosystems for future generations.

    Breeding Birds

    Many network parks have birds that are declining throughout their range, highlighting the need for understanding their status and trends.

  • Sun shining though forest canopy.

    Forest Vegetation

    All Mid-Atlantic Network parks have forests that form an essential part of the landscape and provide habitat for a diversity of wildlife.

  • A small stream in a forest.

    Water Quality and Quantity

    Monitoring water quality & quantity helps the National Park Service fulfill its duty to protect pristine (or improve impaired) park waters.

  • Climate monitoring station in a grassy clearing, with many scientific instruments scattered about.

    Weather & Climate

    Climate is a dominant factor driving the physical and ecologic processes affecting Mid-Atlantic Network parks.

  • A view from an overlook on a mountain looking into a valley with foothills in the distance

    Air Quality

    Park managers benefit from knowing the type and extent of various air pollutants in order to evaluate their impacts on park resources.
