Volunteer Opportunities


The trail cleanup at Birch RocksPratt Glen on Friday, March 29 was a success! A group of around 20 people came out to chain saw, rake clip, and re-route the yellow, blue/yellow, and blue trails. Thank you to all who participated!  Your efforts have made it possible to walk the trails from the Ashwood side to the parking lot, no bushwhacking required. 

Another work day will be organized to address the red trail. Watch you email for an announcement.

Missing: Boardwalk


The boardwalk at Hop Brook Sanctuary was completed in 1998. At around the same time beavers moved in and caused the water level in the entire sanctuary to rise dramatically. Over time, changing water levels and shifting ice caused the boardwalk to float free from its footings. In recent years entire sections were partially submerged or listing dangerously to one side. The only way to correct the problems was to re-build the boardwalk from scratch. BOSLI raised about $6,000 towards the demolition and construction of a new boardwalk, but that was far less than the over $50.000 that would be needed to complete the project. The boardwalk was unsafe and the decision was made to remove it.
