Approximately 450 different plant species have recently been identified in Forest Hill Park, including several endangered species such as hairgrass and withe-rod. The encroachment of native and non-native invasive plants, including Japanese knotweed, tree-of-heaven and buckthorn, are a threat to the endangered plants, as well as to all the plants in the park. The “invaders” also take space that could be available for more desirable plants.
A lagoon and Dugway Brook are the park’s main water features. The lagoon is man-made and is home to fish, turtles, ducks and too many geese. A great blue heron spends many hours decorating the island in the lagoon in summer months.
