The largest of Cheverly’s natural areas, the Boyd Park-Cabin Branch Hub, includes the flood-plains of Lower Beaverdam Creek and Cabin Branch, and Boyd Park. The floodplains preserve the largest patches of wildflowers in Cheverly, perhaps only because they are mostly inaccessible for much of the year. The creeks support species found only around water, such as ducks, herons and kingfishers, beavers, and even the occasional otter. Boyd Park contains a small patch of hardwoods, a hard surface ADA accessible fitness path, a playing field and picnic area, and the Cheverly Community Gardens. The floodplain is already under federal protection, but its vegetation is severely threatened by invasive species.
