St. Hilary’s Open Space Preserve has a friend in the Broom Buster team, a loyal group of volunteers who have worked together to remove French broom on the preserve for over 20 years. In that time, incredible progress has been made to suppress the broom regrowth and allow native species to recover and thrive. Come learn about the importance of invasive species removal and lend a hand!
