COVID-19 Update (June 3, 2020)
TNC’s public preserves in Maryland remain open. We ask all visitors to observe our preserve access guidelines and follow current health and safety precautions, including guidance from 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.
Thank you for helping us in our efforts to protect our visitors’ health and well-being.
Selinger Marsh lies in the rain shadow of the Appalachian Mountains — this area receives the least rainfall in Maryland. Springs on the surrounding slopes provide the water for the marsh, making it an unusual wetland in a otherwise very dry region. This area was selected for conservation for that reason.
Its importance as a breeding ground for amphibians makes the site a priority in order to maintain viable populations of these species in this part of Maryland. It has been protected by TNC since 1985.
