WLT expert birder Emily Szczypek led a group of nine birders along the Charles River to admire resident birds and those who were migrating through the area, plus some other riparian wildlife. This was a joint program with Brookline Bird Club and Menotomy Bird Club. It was a chilly morning, but everyone saw lots of birds and had a lovely time. At the end, they ran into magnet fisher and WLT steward Alessio with a helper at the Mary Early footbridge!
To kickoff the huge annual Earth Day Charles River cleanup, WLT ED Sonja Wadman joined the leadership of DCR and other nonprofits who organize the event along with Waltham Representatives Lawn and Stanley at the Hatch Shell in Boston. Then on April 25, about 125 volunteers of all ages helped remove litter and invasive plants from along the Charles River in Waltham. Most met at Shaw's on River Street, while others worked in "the Island" neighborhood, around the Mount Feake Cemetery, and all along the river path.
WLT officially kicked off its 2026 stewardship season with a lunch for all current and prospective stewards at the Prospect Hill Park Lodge with 34 folks attending. Ranger Adam Green was our host who also assisted WLT ED Sonja Wadman with presentations about what it takes to be a steward and how to identify native versus invasive plants. We then went out into the park to see examples of invasives in the wild, plus admire the new native plant/tree nursery.
