Gallagher Hill is an 11 acre natural area that is part of Mercer Island's open space system that includes 35 parks, 350 acres of open space and over 50 miles of trails. Volunteers recently worked to build a new trail through this open space that serves as an important connection between City Hall on SE 36th Street and residential areas along E Shorewood Drive, encouraging pedestrian access through the area and increasing walkability around the island. Volunteers have begun the process of removing invasive species and replanting native vegetation to facilitate the growth of native plants and trees and restore this open space back to a healthy forest. Such efforts to promote a healthy understory are critical to ensure the success of this natural area.
