Battle Creek Cypress Swamp, the Gatewood Preserve, and Biscoe-Gray Heritage Farm are a trio of county parks located side-by-side in southwest Calvert County. Altogether, the three parks protect over 360 acres on the east bank of Battle Creek, a tributary of the Patuxent River. The creek in this area is surrounded by a noteworthy swamp of Bald Cypress trees and an open tidal marsh filled with cattails.

Battle Creek Cypress Swamp Sanctuary was purchased by the Nature Conservancy in 1957 as its first sanctuary in Maryland. Battle Creek is now operated by Calvert County Parks and Recreation Department. The Sanctuary is approximately 118 acres in size and was established to protect one of the northernmost Bald Cypress swamps in the US. A quarter-mile elevated boardwalk trail leads directly through the swamp and an additional quarter-mile arboretum trail leads through a fallow field of approximately 20 acres. The gardens surrounding the Nature Center and parking lot are productive for spring migrants. The Nature Center at the Sanctuary offers interpretive programs and live animal exhibits.

In 2018, the County acquired the 48-acre Gatewood Preserve, which lies between Battle Creek Cypress Swamp and the Biscoe Gray Heritage Farm. The Gatewood Preserve property was formerly a private residence and includes a house and barns. The majority of the property is open field and pasture that is being restored to grassland and meadow habitats.Interpretive signage regarding pollinator habitat has been added along the edges of the large field visible from the parking area. There is a breathtaking view of Battle Creek from the back of the house; walk down the wooden steps behind the house to access to the marsh via an old pier. You can reach the Battle Creek marsh with just a short ½-mile walk from the parking area via the gravel driveway, then go around the house, perhaps pausing on the deck to enjoy the view. The County’s vision for Gatewood Preserve is to focus on passive recreation such as birding, hiking, nature study, fishing, and paddling. Future improvements may include a floating kayak launch and/or a dedicated fishing pier and a boardwalk. The former residence may eventually be converted to a nature center that would support the county’s outdoor education programs. There are no marked trails or trail map as yet, but eventually there will be a trail system interconnecting with the  trails at Biscoe Gray Heritage Farm and Battle Creek Cypress Swamp Sanctuary.

Biscoe Gray Heritage Farm is an adjoining property acquired by the County in 2002. The development of Biscoe Gray as a park is ongoing; the master plan provides that it will be a showcase for Calvert County’s agricultural heritage and a model for effective stewardship of land and water resources. The property consists of rolling fields surrounded by second-growth hardwood forest that is relatively free of invasive plants. There are traces of a road (the rolling road, or Money Crop Trail) dating back to colonial times that extends from Gray’s Road all the way to Battle Creek, where a 19th century house is located. The farm also includes an early 20th century farm house and many barns and outbuildings. A hiking trail network extends through the property; see trail map at link at left. [Note: on the trail map, the property to the west of Biscoe Gray that is marked as Private Property is now in fact the Gatewood Preserve.] For the birder, the primary attractions at Biscoe Gray are the access to the water and swamps of Battle Creek and the field and forest habitats. Across the road from the Biscoe Gray Heritage Farm is the Gray’s Road Dog Park, consisting of open fenced fields surrounded by woods. One can bird the woods edge outside the fenced area at the Dog Park, or make use of the  portable restroom if the one at Biscoe Gray Heritage Farm is unavailable.

Fun Fact:

On the north side of Gray’s Road, directly across from the parking area of Gatewood Preserve, is a 25-acre wooded parcel that was given to the Battle Creek Nature Education Society in 2010 by our own Chandler S. Robbins. Recognizing the value of the habitat for Forest Interior Dwelling Birds, Chan and Eleanor Robbins purchased the property from the Gray family in 1970 in order to preserve it. There are no trails in this wooded tract, but you can stand in the parking lot at Gatewood Preserve and hear the birds singing, including such goodies as Worm-eating Warbler and Yellow-throated Warbler. Remember to send a spiritual thank-you to Chan and Eleanor when you hear these birds.


Over 144 species have been reported on eBird from Battle Creek Cypress Swamp. The preserve is well known for its breeding population of Prothonotary Warblers, which are relatively easy to see from the boardwalk that winds through the swamp. Many Maryland birders have scored their life bird Prothonotary here. Other nesting warblers include Northern Parula, Louisiana Waterthrush, Ovenbird, Worm-eating, Common Yellowthroat, Hooded, Kentucky, Yellow-throated, and Pine.  There are also breeding Red-eyed, White-eyed, and  Yellow-throated Vireos. This is a great place to spot both Scarlet and Summer Tanagers. Significant winter species include Yellow-bellied Sapsucker, Winter Wren, Hermit Thrush, Swamp Sparrow, and Purple Finch.

A relatively new eBird hotspot at Gatewood Preserve lists 93 species to date (spring 2022). Another fairly new hotspot at Biscoe Gray lists 116 species. With additional visitation by birders, the birdlife at Gatewood and Biscoe Gray will probably prove to be similar to that at Battle Creek Cypress Swamp, with perhaps some additional representation of field and edge species.

Wheelchair Access:

The trails at the three properties are not wheelchair accessible.

Pet Policy:

Pets are NOT permitted at Battle Creek Cypress Swamp, not even on leash. Please let your pet at home.

A 1956 article on Battle Creek Cypress Swamp published in the Maryland Conservationist makes interesting reading. Brent Steury completed a detailed fleuristics survey of Battle Creek Cypress Swamp; his detailed report can be downloaded from

The Nature Center at Battle Creek Cypress Swamp offers a number of programs that focus on the natural and cultural heritage of the area. See the calendar. It may be possible to schedule Ranger-led programs for your group at Battle Creek Cypress Swamp, but requests must be submitted in advance. Biscoe Gray Heritage Farm has proven to be a rich archaeological site, with evidence not only of the colonial area farmers, but also dating back to prehistoric Native American settlements.


The Nature Conservancy has an audio tour of Battle Creek Cypress Swamp, narrated by park naturalist Andy Brown; download the audio tour here.

Local MOS Chapter:

There is no chapter of the Maryland Ornithological Society specific to Calvert County, but many birders participate in MOS through the Anne Arundel Bird Club or the Patuxent Bird Club; both of these MOS chapters offer field trips and meetings with informative programs, all free and open to the public. In addition, the Southern MD Audubon Society serves birders in Charles, Calvert, St. Mary’s, and Prince George’s Counties.
