“Mini Meadow” Completion

Mashomack is home to more than 50 acres of open meadows that are filled with native plant species crucial for pollinators and other local animals. With the help of local garden expert and Mashomack volunteer Tim Purtell, we have planted a “mini meadow” near the Visitor Center so that anyone can easily experience pollinators hard at work amongst the native plants, without having to venture out onto the trails.

Sitting amongst the goldenrod and butterfly weed, Tim begins planting Little Bluestem, a grass native to Long Island.

We still have space left for our August work days. Are you interested in volunteering at Mashomack or one of our other Nature Conservancy preserves on Long Island? Join us for a Volunteer work day where we’ll be tackling various stewardship projects including native pollinator and bioswale garden maintenance, split-rail fence removal, trail maintenance and more.

Why Are Mangroves Important?
