Spring BeautiesThanks to volunteer support, we created an area at Merrimac Farm WMA where people and the environment can come together as one. It's a great area to watch wildlife, learn about native plants and pollinators, and get ideas for your own backyard.

We need help maintaining this high quality habitat, including keeping a check on pesky invasive plants! We're especially looking for people who can commit to be present at two work days every month, through September (about six hours/month). And if you can come just once or twice, your help will make a difference. Wear long pants, sturdy shoes, and long socks.

Questions and RSVP (appreciated) to alliance@ or 703-499-4954.
