  • The Accelerating Erosion of Dyke Marsh Basic Findings of the U.S
    The Accelerating Erosion of Dyke Marsh Basic Findings of the U.S. Geological Survey Study In 1940, the wetland known as Dyke Marsh was around 180 acres. By 2010, it was around 53 acres. Ned Stone It is eroding six to eight feet or 1.5 to two acres per Dyke Marsh shoreline erosion year on average. “Analysis of field evidence, aerial photography, and published maps has revealed an accelerating rate of erosion and marsh loss at Dyke Marsh, which now appears to put at risk the short term survivability of this marsh.” – USGS At this rate, Dyke Marsh could be gone in 30-40 years. Dredging of sand and gravel from 1940 to 1972 was a strong destabilizing force, transforming it from a net depositional state to a net erosional state. Dredging removed around 101 acres or 54 percent of the 1937 marsh. Erosion is both continuous and episodic. The chang- es caused by dredging have made the marsh subject to significant erosion by storm waves, especially from winds traveling upriver. Damaging storms oc- cur approximately every three years. Dredging out a promontory removed the geologic wave protection of the south marsh that existed back to at least 1864 and altered the size and func- tion of the tidal creek network. “This freshwater tidal marsh has shifted from a semi-stable net depositional environment (1864– 1937) into a strongly erosional one . The marsh has been deconstructed over the past 70 years by a combination of manmade and natural causes. The 1937 1959 2006 marsh initially experienced a strong destabilizing period between 1940 and 1972 by direct dredge The USGS study can be found at: www.pubs.usgs.gov/of/2010/1269.

  • Why Is Dyke Marsh Significant?
    Why Is Dyke Marsh Significant? The Dyke Marsh Wildlife Preserve is a 480-acre complex with several habitats — a freshwater tidal wetland, swamp forest, upland forest and open water. It is on the Virginia side of the Potomac River in Fairfax County and has been seriously degraded by dredging, dumping, filling and the introduction of non-native species. Congress added Dyke Marsh to the National Park System in 1959 “so that fish and wildlife development and their preservation as wetland wildlife habitat shall be paramount.” (Public Law 86-41) What is it? What’s there? Dyke Marsh is — a freshwater tidal marsh and freshwater tidal marshes are rare. one of the largest remaining freshwater tidal wetlands in the Washington metropolitan area. one of the largest, most significant temperate, climax, riverine, narrow-leafed cattail marshes in the national park system. habitat for 300 known species of plants, 6,000 arthropods, 38 fish, 16 reptiles, 14 amphibians and over 270 species of birds, and at least 20,000 species of insects. Officials estimate that 90 percent of the marsh’s microhymenoptera are not yet described. home to the narrow-leafed cattail (Typha angustifolia), a plant more common to salty water. one of the best studied wetlands in the U.S. and an outdoor laboratory for several area universities. at least 2,200 years old, in the southern part.

  • Dyke Marsh Wildlife Preserve, a Chronology
    Dyke Marsh Wildlife Preserve, A Chronology www.fodm.org 1800s - Landowners built dikes and tried to convert the marsh into places for ships to tie up and into pasturelands. 1930s - Smoot Sand and Gravel acquired 650 acres from Bucknell University. 1932 - The National Park Service built the George Washington Memorial Parkway. 1940 to 1972 - Smoot Sand and Gravel dredged at least 270 acres of sand and gravel and the swamp forest wetlands of the promontory on the south end of Dyke Marsh and built the Haul Road. 1947 - Spring in Washington by Louis J. Halle, published by the Johns Hopkins University Press, highlights spring's rebirth in Dyke Marsh and other natural areas of the Washington metropolitan area. 1959 - Congress passed and the President signed on June 11 P.L. 86-41, adding the Dyke Marsh Wildlife Preserve to the National Park System "so that fish and wildlife development and their preservation as wetland wildlife habitat shall be paramount." Congressman John Dingell (D-Michigan), one of the authors of the legislation, stated, "We expect that the Secretary will provide for the deposition of silt and waste from the dredging operations in such a way as to encourage the restoration of the marsh at the earliest possible moment." 1974 - Congress passed and the President signed P.L. 93-251 which authorized the U.S. Army Corps of Engineers to assist NPS in planning, designing and implementing the restoration of Dyke Marsh. 1975 - Smoot Sand and Gravel relinquished their mining rights. 1976 - The Friends of Dyke Marsh was formed and incorporated. 1977 - The National Park Service prepared an environmental assessment proposing management options for Dyke Marsh, including "attempt re-establishment of portions of the dredged marsh." 2004 - The University of Maryland, Center for Environmental Science, Appalachian Laboratory held a workshop titled, "Should We Restore Dyke Marsh"? 2007 - The Water Resources Development Act directed NPS to restore Dyke Marsh.
