Conservation Connections

In April, 17 Conservancy stewardship team members from across New York State joined us at the preserve. Together, the team worked to reroute a portion of our Green Trail where erosion of the coastal bluffs was beginning to undermine the trail. Erosion is a natural process that rebuilds beaches and is part of a dynamic coastal ecosystem. The team also worked to clear a new picnic area on the bluff overlooking one of the popular vistas where South Ferry can be seen making its regular crossings. Visitors also have a picturesque view of our beloved osprey nest sitting atop a large coastal boulder. But the work isn’t done! This month, the preserve welcomes veterans from the Strongpoint Theinert Ranch who will install split-rail fencing along the new trail and seating area on the bluff. Check back in our June newsletter to see the completed project!

The warmer weather months are filled with exciting programs at Mashomack. We’ll be hosting a nature writing workshop, a reading with local children’s author, guided hikes, paddles and more! See below for a sample of upcoming programs and stay up-to-date with new ones at nature.org/events. Advanced registration is required for most programs.
