Weeding for Wildlife: Saving Monarch Butterflies

Sunday, July 20th, 2025


We need volunteers to help spend a couple of hours weeding in beautiful conservation land in Cohasset. 

 Our target: Black swallow wort, an aggressive invasive plant that is killing monarch butterflies 

& poses a major threat to biodiversity.


  • Meet 9:45 am in the parking lot at Holly Hill Farm, 236 Jerusalem Rd Cohasset.  Carpooling is recommended as parking is limited.
  •  At 10 am, we'll hike to the spot (approximately 10 minutes away through fields and over uneven ground).
  •  Sleeves, pants and gloves are recommended!  
  • If possible, please bring garden clippers and/or a dandelion weeder or sharp trowel. (we will have extras on hand)
  • No experience necessary:  we'll show you what to do!
