Comprised of a 50-foot rock cliff, Warren Gardens Urban Wild is bordered by Warren Street, Richard Street, Circuit Street. Perhaps the most important aspect of this urban wild is its historical significance as one of the last remaining markers of Old Roxbury. Today, the area still provides a quiet natural respite within the dense urban setting. The majority of the outcrop is vegetated by a mixed deciduous forest of oaks, red maples, and black cherry. However, near the summit, a small section opens up into a cool, grassy field. Norway maple, European buckthorn, and multiflora rose have significantly invaded portions of the site. Earthworks has performed some invasives removal and replanting with native species. New plantings include sugar maple, juneberry, balck and red chokecherry, white birch, gray dogwood, green and white ash, red oak, nannyberry, and white pine.
