Winter brings several species of migratory waterfowl to the Potomac River and Dyke Marsh and many birds stand out as they perch on leafless tree limbs, search for prey and forage on the ground. Still some, like barred owls (Strix varia) are expert at camouflaging.
For at least 15 years, the Friends of Dyke Marsh have worked to control many species of invasive plants in the preserve. Invasive plants displace native plants and replace wildlife food sources with which native wildlife co-evolved.
