Activities and Volunteer Events

Parking Alert

The U.S. Park Police are ticketing vehicles parked on either side of the Marina Road. While the signage may be confusing, an officer on May 6, 2023, told us that except for the two marked handicapped parking spots near the Mount Vernon Trail, only vehicles with attached trailers can park on the sides of the Marina Road.

Birding Led by Experts

FODM hosts birding led by experts every Sunday at 8 a.m. Meet in the Belle Haven Park south parking lot. We will cancel if weather conditions are unsafe, such as lightning, ice or heavy rain or snow. Because of the annual Audubon Christmas Bird Count, we will not have Sunday walks on December 20 and 27, 2026, and January 3, 2027.

Help Tackle Invasive Plants

Help protect native plants by pulling and clipping invasive plants. We will train volunteers to identify the five or so target plants. We kindly ask that you not bring pets. Invasive plants can threaten and outcompete native plants.


Bring gloves, hand clippers and water. We will supply instructions, examples and trash bags. Wear long sleeves and pants and sun protection. We will have some tools to share. We will cancel if lightning or severe storms are anticipated.

Meet at the Haul Road trail entrance bench. If it is raining one hour before a scheduled session, we will cancel it.
