What We've Been Up To

Oaks 4 Oak

GSG has partnered with Sun Harbor Nursery in Indian Harbor Beach to provide native Oak trees to help beautify the Oak Street corridor in Melbourne Beach. Phase 1 successfully saw 2 trees planted at Advent Lutheran Church this past Arbor Day and in Phase 2, GSG will present our proposal to the Melbourne Beach Town Commission requesting to plant at least two additional trees along the street. Oak trees are native, support biodiversity, lower the ambient temperature, and reduce CO2 in the atmosphere. Please attend the meeting on May 15th to support the proposal.
