Tucked between the Forest Hills Station and the Arnold Arboretum, the Bussey Brook Urban Wild, also called the South Street tract, has recently been incorporated into the arboretum. As part of the annexation, a stabilized stonedust pathway was constructed through the wild from Forest Hills Station to South Street. Select areas were cleared of prior vegetation and replanted. However, the majority of the site remains in its former condition. Boasting a small section of the Stony Brook, this is the last area where the brook can be seen before it is funneled into the conduit to the lower basin of the Charles River. As a low-lying area, the wild is composted of a marsh and upraised filled land.
