Welcoming Fall at Mashomack

Volunteers Making a Difference

Mashomack has hosted several successful volunteer work days through the changing of the seasons. From participating in coastal cleanups to uncovering antique farm equipment in our meadows, volunteers have helped the preserve and stewardship staff in many of our efforts.

Saying “So Long” to our Seasonal Staff

Every year, dedicated staff join our team at Mashomack for the summer months, helping to support our education, conservation and stewardship programs. From weeding and trail mowing to meadow management and teaching, this summer our seasonal staff did it all while advancing their conservation careers. We wish them well and look forward to seeing where their paths will lead.
