Stewardship Saturday Program 2018: 9 a.m.-noon Aug. 18, Wright Farm, 241 Grove St., Lexington. Join the Lexington Conservation Stewards on the third Saturday of each month for work and camaraderie and help maintain Lexington’s beautiful open spaces. Aug. 18th – Japanese stiltgrass pulling at the Wright Farm Conservation Area. Join the Stewards as we pull japanese stiltgrass, an early-detection invasive plant, from the meadow areas at Wright Farm. The work is easy and satisfying and the result will be a meadow comprised of native and wildlife-friendly wildflowers and grasses, not invasive species. In the event of inclement weather, contact the conservation division for cancellation information. We will provide all tools and know-how, just bring work gloves, work appropriate clothing (no open-toed shoes) and a willingness to work. RSVPs are helpful, but walk-ins are welcome. Contact Jordan McCarron, Conservation Stewardship Program coordinator: jmccarron@lexingtonma.gov or 781-698-4532.
