Dyke Marsh Restoration Is in Full Swing

Crews operating barges, cranes and boats are at work this fall, 2018, building the breakwater in the Dyke Marsh Wildlife Preserve, the first stage of Dyke Marsh restoration.  The U.S. Geological Survey’s 2010 and 2013 studies identified building a breakwater as the first priority of restoration, a riprap structure designed to replicate the historic promontory removed by dredgers.

Dyke Marsh’s Submerged Aquatic Vegetation

Several FODMers learned about native and non-native submerged aquatic vegetation (SAV) of Dyke Marsh and the Potomac River on July 14, 2018, when Nancy Rybicki gave a tutorial and led a paddle.  Dr. Rybicki is an aquatic plant ecologist and wetlands scientist, retired from the U.S. Geological Survey.  In her 37 years of studying the vegetation of the Potomac River, she has correlated the presence of submerged aquatic vegetation with water quality.

Butterflies, Dragonflies, Damselflies Delight

On a beautiful, 82-degree, breezy July 7, 2018, 15 FODMers studied butterflies, dragonflies and damselflies and their host plants in the Dyke Marsh Wildlife Preserve and Belle Haven Park.

It was a Needham’s skimmer (Libellula needhami) day. These showy dragonflies were whizzing around everywhere and eating midges, making for easy sightings.  The males are bright reddish-orange and have a red face.  The females are yellow and black.  Both sexes and all ages have a black line on their abdomens and orange-tinted wings.

He also discussed human intervention and how native Americans used some of the marsh plants.
