Straddling the East Machias River, the Rocky Lake ecological reserve supports a diverse 500+ acre streamshore ecosystem. Much of this streamshore is emergent wetland, including two peatland areas identified as acidic fens. The streamshore also includes a small but interesting floodplain forest on a river levee. Floodplain forests with silver maple are uncommon in this region of the state, and one silver maple was measured at 64 inches in diameter.

Upland forests within the reserve are unremarkable and characteristic of Downeast Maine. Much of the upland acreage is a post-burn association of red oak, red maple, bigtooth aspen, and red and white pine. According to BPL stand type maps, only 10% of the acreage is within the sawtimber class. Conifer dominated stands indicate a heavy past influence of spruce budworm.
