COVID-19 Update (March 30, 2020)

TNC’s public preserves in Maryland remain open. We ask all visitors to follow current health and safety precautions, including guidance from the Governor’s Stay-at-Home order issued March 30, 2020, the Maryland Department of Health and the Centers for Disease Control (CDC), including maintaining a distance of at least 6 feet from others (social distancing).

Parking may be limited at many of our preserves. If parking areas are full, please plan to return to the preserve another day.

If you choose to visit a TNC preserve, please follow preserve access guidelines, and check back here for updates as the current situation is changing rapidly.

Thank you for helping us in our efforts to protect our visitors’ health and well-being.

The Maryland/DC Chapter helped the State of Maryland acquire this important area which contains approximately 70 acres of wetland in the floodplain of the Little Patuxent River. 

The key feature of this preserve is the Little Patuxent Oxbow, an impoundment of the Little Patuxent River that was created over hundreds of years by beaver activity. Another important element is Laurel Oxbow Lake, which is the largest naturally occurring body of freshwater in Maryland; other lakes are the result of damming creeks.

Management activities include maintaining and improving trails, controlling invasives, and preserving forest growth. 

 

What to Look For

Naturalists have found more than 100 native vascular plant species at Oxbow Nature Preserve, including rare species such as the Water-shield (Brasenia schreberi) and dodder (Cuscuta polygonorum). The preserve is also home to the popular wildflowers blue-flag iris and cardinal flower.

Visitors to Oxbow might hear the high piping whistle of the northern spring peeper (Pseudacris crucifer). This type of frog can be found in brushy second growth near ponds or wetlands. More than half of this site is covered with shallow water even during the dry summer months, resulting in a specific type of aquatic ecosystem.

Oxbow is a birders delight, with more than 150 species identified here, including the bald eagle, little blue heron, egrets, ducks, greese along with coopers and red-shouldered hawks. 

The evergreen mountain laurel blooms the last two weeks in May, while blueberry bushes yield their ripe fruits in the summer. Pitch pines and Virginia pines can also be found at Oxbow. One noticable feature of this preserve is the prevalence of snags, or dead trees, that provide habitat for a variety of species.. Most of these trees have been girdled by beavers, struck by lightning, or killed by disease.
