Earlier this month, Troop 1 - Mendham, NJ Scout Liam Shaw led a group of 16 of his fellow Scouts and 6 Adults in making improvements to a heavily used section of Patriots Path in the Dismal Harmony Preserve. They spent over 120 total labor hours constructing steps, clearing invasive shrubs and planting native pollinator bushes. Liam undertook this as his Eagle project, following a suggestion from the Mendham Township Environmental Commission. Mendham Township DPW assisted by providing gravel and some removal of poison ivy. This section of trail is accessible from the trail parking lot on East Main St in Brookside. Thanks Liam for all your hard work on this!
