Many visitors to Dyke Marsh who walk along the Haul Road trail have questions about the cleared area on the west side of the trail across from “Dead Beaver Beach.”The answer: The National Park Service and FODM are creating a demonstration plat, clearing the area of a massive invasive plant infestation and eventually planting some native plants.
The bright, scarlet cardinal flowers (Lobelia cardinalis) blooming in Dyke Marsh in August and September 2017 are delighting many visitors, including migrating hummingbirds. “The tube-shaped flowers have two lips, the upper having two lobes and the lower lip so fragile, many insects cannot land on the plant to reach the nectar,” according to the guidebook, Walking the Wetlands.
A stand of native clematis, Clematis Virginiana, has been growing on a shrub along the “long bridge” (bridge 23) in Dyke Marsh on the Mount Vernon Trail. This is not the same as the non-native clematis that FODM “weed whackers” try to control, a plant called sweet autumn clematis or Clematis Terniflora.
On July 1, 2017, several FODMers and members of the Westgrove PACK (Pumphouse Association for Canine Kindness), the dog park friends’ group, visited the completed Quander Road outfall project, west of the dog park and Dyke Marsh West.
This year, 2017, there seem to be more marsh wrens (Cistothorus palustris) occupying the Dyke Marsh Wildlife Preserve than at any time since 2014 when FODMers last recorded this bird as a breeder. Data from volunteers this year suggest there may be as many as five territorial males in the marsh. This does not necessarily mean the population is recovering. Avian males appear more willing to occupy degraded or marginal habitats than females and, sadly, we have had no reports of females alone or as part of a breeding pair in Dyke Marsh since 2014.
It was all about geology, plants, forests, wetlands, uplands, birds, mammals, reptiles, insects, how everything interrelates and more on the June 10, 2017, ecology walk with Charles Smith, expert naturalist and Chief of Fairfax County’s Stormwater Planning Division, Watershed Projects Implementation Branch.
One of Dyke Marsh’s neighbors, the Belle View Elementary School, has created outdoor classrooms over the last ten years which help restore and support our natural resources, including the Dyke Marsh Wildlife Preserve.
The 600-student school is just west of Dyke Marsh West. What happens upstream has effects downstream, especially for water quality. For species like birds, moths and butterflies that move throughout the environment, creating some natural connectivity and supportive habitat can be very important.
An osprey (Pandion haliaetus) family near the boat ramp of the Belle Haven Marina has provided fans and photographers many prime raptor-watching opportunities this spring, 2017. The two adults are raising three young.
Rising third graders from St. Philip the Apostle Catholic School, Camp Springs, Maryland, were intrigued by the black “patent leather” beetle or horned passalus (Odontotaenius disjunctus), during their June 1, 2017, visit. NPS Ranger Mireya Pasa urged the youngsters to touch the beetle and pointed out the insect’s distinctive mandibles.
On May 31, 2017, eight enthusiastic FODMers planted another 30 native shrubs and trees along the Haul Road trail east of the “dogleg” turn along the trail, led by NPS staffers Melissa Westbrook and Colin Davis. This planting was in addition to the 40 plants put in on April 25, 2017.
On May 20, 2017, a class led by Joel Cohen, Audubon Naturalist Society, visited the Dyke Marsh Wildlife Preserve to study biodiversity. A common wetland plant in the marsh, spatterdock (Nuphar polyspala), was in bloom, sporting its bright yellow, golf-ball-like flower.
On May 20, 2017, FODM exhibited at the 20th annual Mason Neck Eagle Festival. Glenda Booth and Marc Ribaudo, pictured here, staffed the table in the afternoon; Ned Stone and Trudi Hahn, in the morning. A steady stream of youngsters made colorful birds at the FODM table and a “foxy” ranger visited.
