Mashomack Preserve Virtual Benefit 2020

New York

Mashomack Celebrates 40 Years!

Connecting People, Nature & Community

Our annual benefit takes a different form this year—but we can still be together in spirit by showing our love and support for nature at this virtual celebration of Mashomack Preserve. For the past 40 years, you have been our partners in protecting over 2,000 acres for all of nature, including people. Now join us as we celebrate the next 40 years of research, education, inspiration and partnership at Mashomack.
