As global biodiversity faces unprecedented challenges, Berkshire Environmental Action Team (BEAT) is bringing the community together to celebrate and explore the rich variety of life found in the Berkshires.
The 17th annual Berkshire Biodiversity Day, also known as Berkshire BioBlitz, invites nature lovers of all ages to join scientists, naturalists, and environmental educators in identifying as many species as possible—plants, animals, fungi, and more—over the course of 24 hours.
The event will take place from noon on Saturday, September 19, to noon on Sunday, September 20, at Bartholomew’s Cobble, a property of The Trustees located at 105 Weatogue Road in Sheffield, MA. Participation is free and open to everyone, regardless of age or experience.
Attendees are invited to drop in at any point during the event to join scheduled guided walks, attend hands-on demonstrations, and learn from expert-led presentations.
All activities and presentations will be based at Bartholomew’s Cobble, where attendees must register upon arrival. Participants may stop by anytime to take part in the scheduled guided walks, live demonstrations of surveying techniques, and educational presentations, or contribute their own observations to the species survey across the Cobble’s diverse 357-acre landscape.
A full schedule of guided walks and presentations will be available soon—stay tuned!
Berkshire Biodiversity Day is organized by Berkshire Environmental Action Team (BEAT). This year’s program is co-sponsored by The Trustees of Reservations and BEAT.
