The Silver Maple Forest (Belmont Uplands) & The Impact of Development

1. The Silver Maple Forest (Belmont Uplands) & The Impact of Development Charles J. Katuska, MFS,PWS Consulting Ecologist “The aesthetic, wildlife, watershed protection, and wood production values of these (suburban) woods will increase in every future decade” - Lloyd Irland

2. What Is It ? • The Belmont Silver Maple forest is a mixed association of various wetland and upland plant communities on about 15 acres. • Silver maple (Acer saccharinum) dominates the central core of the site. • Unusual, relict forest community in this context

4. Silver Maple (Acer saccharinum) A native floodplain tree species with specific autecological values - • Provides an important wildlife food resource (newly broken buds) at a critical time of the late winter • High value food source for beaver, second only to alders • High value for cavity-nesting wildlife • Shallow fibrous root system well adapted to reducing erosion and stabilizing soils

5. This well-grown, diverse, and regionally uncommon forest stand exists in a unique context

7. The Belmont Silver Maple Forest Forested land always provides value to the urban environment • Maintains and improves air quality • Maintains and improves water quality • Reduces volumes of stormwater runoff • Provides important wildlife habitat • Recreation • Aesthetics • Educational Value

8. The Belmont Silver Maple Forest Provides additional site-specific functions and values here - • Serves as an important “core habitat” adjacent to Little Pond and the Alewife Reservation • Size and Shape • Land Cover Type • Relative Seclusion in Context • Provides a significant reserve within a network of other habitat patches for the continued preservation of area-sensitive species

9. Now, the Belmont Silver maple Forest is the site of a substantial development proposal -

10. How would the Development (commercialor residential) of the Silver Maple Stand affect Forest values ? • Add pollutants and additional stormwater volume to an already stressed receiving water system • Directly eliminate core wildlife habitat and reduce the quality of remaining habitats • Reduce air quality in the immediate area and contribute to local/regional air quality problems • Eliminate the opportunity for recreation in the development area itself and reduce the quality of the recreation experience in undeveloped portions of he site • Eliminate the locally unique and regionally significant floodplain forest aesthetic experience

11. Final Considerations • The environmental values of the Belmont Silver Maple Stand are not solely related to wildlife habitat or the protection of its surrounding wetlands. • The development of the Belmont Silver Maple Stand will substantially eliminate its forest values and will degrade the forest & forested wetland values of the remaining land and the adjacent public open space. • Potentially significant forest values do not flow to the community under current private ownership.
