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.
Check out an aerial photo of Nanjemoy Creek in Charles County and you’ll see why it has been called “the green thumb” of the Potomac River — about 80 percent of the land in the Nanjemoy watershed remains forested.
Relatively few roads carve through these woods, though human activities like residential development and incompatible forestry threaten this emerald-green oasis. The Nature Conservancy has embraced the challenge: retain the character of one of the state’s most pristine watersheds, where just eight percent of the land is currently protected.
TNC has identified a project area of more than 48,000 acres offering the rare opportunity to save and restore this enormous block of contiguous forest. This remarkable situation exists, in part, because the landscape has not been fragmented as it has in other places — only about 150 private landowners own 25,106 acres (76 percent) of the unprotected land here.
Since establishing Nanjemoy Creek Preserve in 1978, TNC has worked to assemble the forest puzzle, helping conserve more than 3,510 acres to date (3,204 of which is the Conservancy's preserve).
