Riparian Buffer Experiment @ Stroud Preserve/Georgia Farm

Field Areas     

◀Prev       Next►

The Stroud Preserve riparian reforestation project is a demonstration of the three-zone Riparian Forest Buffer System (RFBS) developed by the U.S.D.A. Forest Service. Between 1992 and 2009, the project involved three experimental agricultural watersheds in the Stroud Preserve, a southeastern Pennsylvania farm protected by conservation easements.

The reforested buffer surrounds the headwaters of Morris Run, in one of three experimental watersheds on the Stroud Preserve, near West Chester, Pennsylvania, USA.

  • Setting & Research

    The streams are in the drainage of the Brandywine River, which flows into the Delaware Estuary. Prior to 1992, all three watersheds were primarily in crop production (maize, soybeans, hay) under a soil conservation plan including contouring and crop rotation. Water quality was compromised by elevated nutrients and suspended sediments. The primary objectives of the riparian reforestation project were to:

    1. Evaluate the non-point source reductions of the RFBS in the relatively high-relief terrain of the Mid-Atlantic Piedmont
    2. Assess the time required after reforestation to achieve significant mitigation
    3. Establish specific guidelines for planting and managing forest buffers zones in the mid-Atlantic region

    There is an exceptionally long climate record for the Christina River Basin. Our figures are based on 115 years of NOAA data back to 1894 with at least one station per year having at least 360 days of non-missing records in the given year.
