Old 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 the past 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!

All skill levels are welcome and no previous experience is necessary. All ages are welcome; anyone under the age of 18 must be accompanied by a supervising adult. Dress in layers you can get dirty, wear sturdy shoes, and bring water. Please bring gloves if you have them. Snacks will be provided.
