Mashomack's "Dirty Dozen"
Saturday, April 9 | 9 AM-noon

Is bittersweet an attractive vine useful for decorative purposes or a scourge? Phragmites, nice to look at in a vase, appears un- welcome in wetlands. Come take a 3-mile walk and learn the identity of the exotic and introduced plants which pose a threat to our native flora, the ecological and economic impacts of invasives and what The Nature Conservancy is doing to control these species.

Take Action on Earth!
Saturday, April 23 | 10 AM-noon 

Celebrate Earth Day by grabbing a pair of work gloves and doing some hands-on work at Mashomack! We hope to wood chip areas of our most-used trails to help prevent erosion and soil compaction. Help protect tree roots and reduce runoff. Community service hours documentation available. Bring work gloves. Call the Mashomack office at (631) 749-1001 for further information or e-mail us at

Birding for Beginners
Sunday, April 24 | 8-10 AM

May-gration Bird Walk
