Lois Y. Green Conservation Park
8711 Snouffer School Road, Gaithersburg, MD 20879
The Lois Y. Green Conservation Park (aka Green Farm Conservation Park) consists of a 200-acre parcel that Mrs. Green gave to Montgomery County Parks in 1975, plus an additional dedicated stream buffer area of 50 acres. When Mrs. Green donated the park, she specifically directed that the park was to “be used as an open space, for parkland, and for recreation in such a manner as to evidence the conservation of soil, water, woods, and wildlife… and shall be maintained essentially in its natural condition…” Today the Park is a remarkable oasis in a highly developed area of Montgomery County. The expanse of the park’s grasslands, topography, tree-lined stream, large ponds, wetlands, and woodlands create a feeling of respite and retreat.
The park offers a good diversity of habitats, with a large expanse of meadow, woodlands, and a stream valley. The trails are well-maintained; be aware that there are some steep sections. There are two small ponds that can be attractive to waterfowl in the colder months. Walk the grassy trail from the parking lot, beneath the takeoff/landing path for the adjacent air park, and watch/listen for activity in the woods to the left and overgrown field to the right. Use any of the three loop trails farther along; these are shown on the trail map at the link at left. Approach the ponds stealthily to avoid flushing waterfowl.
Note that on the trail map, trails designated as “Shared by All” are used by hikers, bikers, and equestrians, while the Butterfly Loop Trail is restricted to foot-traffic.
Over 170 species have been reported on eBird from Lois Y. Green Conservation Park, a remarkable number in such a highly developed suburban neighborhood. Dabbling and diving ducks are found in both ponds in winter. Look for passerine migrants in the hedgerows and forested areas. Breeding Field Sparrows and Eastern Bluebirds are found in the more open, overgrown field areas. Prairie Warblers breed here in spring and Palm Warblers pass through in fall. Raptors can be seen in both spring and fall. Sparrows, juncos and towhees are regular in fall, winter, and spring.
The native plants create excellent habitat for butterflies and other pollinators in the warm months. ◾ The local chapter of the Maryland Ornithological Society is the Montgomery Bird Club, which offers field trips and meetings with informative programs, all free and open to the public. ◾ The Montgomery Bird Club has published A Birder’s Guide to Montgomery County, Maryland; this comprehensive, detailed printed book covers 17 major birding sites plus 18 “little treasures” in the county. To order, see https://mdbirds.org/join/merchandise/a-birders-guide-to-montgomery-county/. ◾ Montgomery Parks has an interactive map available at https://mcatlas.org/parks.
