About FODM

DrWellsDr. Elizabeth Wells leads plant walks in Dyke Marsh. Photo by Glenda Booth.The Friends of Dyke Marsh (FODM) was formed in 1975 by a group of local people who, initially, wanted to stop plans to use the marsh as a dumping ground for dredged river spoil. This was yet another insult to the wetland; in the 1930s, construction debris had been heaped into the marsh and some of it is still visible today. The group formally organized as a non-profit organization for the purpose of cooperating with the U.S. National Park Service (NPS) in promoting the well-being of the marsh and preserving and restoring it. FODM was incorporated in 1976.

Since 1975, the Friends have continued and expanded their volunteer work. Our efforts include holding quarterly meetings and other programs open to the public; publishing a newsletter titled The Marsh Wren; raising money to sponsor scientific studies of the marsh; conducting nature walks; conducting surveys, including the annual breeding bird survey; hosting trash cleanups; preparing informational materials; encouraging public stewardship; maintaining this website and a Facebook page; and helping NPS control invasive Lew CabeLew Cabe is a member of the FODM team that works to control non-native, invasive plants.

The Friends also advocate for conservation and restoration and oppose inappropriate activities that degrade the health of the marsh as a wildlife habitat. For a more complete history of the park and the Friends of Dyke Marsh, see Dyke Marsh Wildlife Preserve, A Chronology.

Our Mission

The Friends of Dyke Marsh is dedicated to preserving, protecting and restoring the Dyke Marsh Wildlife Preserve, in cooperation with the National Park Service, as a vital wildlife habitat, through education, science and stewardship. Our vision is that Dyke Marsh is once again a healthy, vital, self-sustaining, biodiverse ecosystem.

Thanks go to our many supporters, including many public officials.

 

FODMers Work to Protect and Restore Dyke Marsh

Some Examples of What We Do
Sponsor programs

Larry BrindzaCaroline SeitzMonarch butterfly expert Larry Brindza gave a presentation to FODMers describing how he catches and tags monarch butterflies.

Caroline Seitz of Reptiles Alive used live reptiles in her presentation to FODMers. This alligator is not found in Dyke Marsh.

 

Support Science

DisplayHerpsFODM supported a dragonfly and damselfly survey in the preserve, conducted by Chris Hobson of the Virginia Natural Heritage Program, which he presented at a FODM meeting in 2012. 

FODMers conduct surveys, for example, of reptiles and amphibians.

 

Lead nature walks

WalksSalamoneFODMers lead bird walks every Sunday morning at 8 a.m.

 

Pat Salamone co-leads a plant walk every fall.

 

Conduct surveys

Larry CartwrightLarry and LauraFor over 20 years, FODMers have conducted a breeding bird survey. Larry Cartwright organizes it, compiles records of breeding birds and submits data to the National Park Service.
     Larry Cartwright, leader of the annual breeding bird survey, and Laura Sebastianelli surveyed birds in the western part of Dyke Marsh for the first time in July 2015.

Introduce decision-makers to Dyke Marsh

      On October 24, 2013, Department of Interior Secretary Sally Jewell came to Dyke Marsh to announce the award of a $25 million grant to restore Dyke Marsh. Seated:  Congressman Jim Moran; Secretary Jewell; Virginia Senator Tim Kaine; Virginia Delegates Rob Krupicka and Scott Surovell.

Host school and other groups

 Students from nearby Belle View Elementary School visit Dyke Marsh.  NPS Ranger Emily Zivot helped us describe the spatterdock to them.

Encourage public stewardship

Educate the public

Organize trash cleanups

TrashGirl ScoutsFODMers participate in the annual Alice B. Ferguson Potomac River Trash Cleanup every spring and conduct other cleanups throughout the year.

Community groups like the Girl Scouts help us clean up trash. 

Attack invasive plants

The Dyke Marsh Wildlife Preserve, like many Northern Virginia properties, is unfortunately riddled with non-native plants. Areas on both sides of the Dyke Marsh Haul Road, the walking trail, are particularly overwhelmed with invasives, like many areas in northern Virginia. Invasive plants are often found in disturbed areas. The Haul Road, as fill, is a classic example. It was built as a service road by the people who dredged and hauled away half of Dyke Marsh between 1940 and 1973.     Fortunately, the National Park Service (NPS) is trying to better control these plants, but it is truly an uphill battle. Non-natives do not co-evolve with native insects and other animals and usually provide little food value to wildlife. NPS biologist Erik Oberg calls invasive plants like bush honeysuckle “junk food” for birds. Plants like orcelainberry and English ivy can outcompete, destroy and smother native, understory plants.     Porcelainberry vines smother trees, shrubs and plants in summer and fall (see photo, left by G. Booth). NPS staffers, including Erik porcelainberry vinesOberg and Kenneth Adams, train and lead groups in tackling invasive plants all along the George Washington Memorial Parkway.    Ned Stone, FODM’s Vice President, also leads volunteers regularly. Thanks to the efforts of many people, many of the formerly abundant bush honeysuckle plants are gone. FODM volunteers and NPS staffers have also planted some native plants, especially along the section of the Haul Road east of the “dogleg” turn. On November 7, 2014, FODMers were joined by three young adults from the Student Conservation Association. We tackled sweet autumn clematis vines, English ivy, porcelainberry and bush honeysuckle primarily. We need more help.
