The City of Cambridge is notifying residents, businesses, and visitors of multiple temporary street closures throughout the weekend due to scheduled community events on May 16-18, 2025. Events include Saint Anthony’s Santo Cristo Feast, Port Art Fest, the Peoples Party Music Festival, the 72nd Annual BB&N Circus, and Inman Eats & Crafts.

Cambridge is home to over 80 species of edible wild plants, some of which are more nutritious and/or flavorful than their cultivated counterparts. These include native species like Fox Grape and Shagbark Hickory; non-native weeds like Chicory and Burdock; and invasive species like Japanese Knotweed and Autumn Olive. Join expert forager Russ Cohen on a 2.5 hour ramble around Fresh Pond to learn about over two dozen species of edible wild plants. Keys to the identification of each species will be provided, along with info on edible portion(s), season(s) of availability and preparation methods, as well as guidelines for safe, ethical and environmentally-responsible foraging. NOTE that this is an educational walk only: no actual foraging will take place, as that activity is prohibited with in the Fresh Pond Reservation. We will meet at Fresh Pond, in the main parking lot by the ranger station and water department. Russ Cohen is a naturalist and wild foods enthusiast from Weston, Mass., currently in his 52nd year of leading walks and talks about wild edibles. He has led talks for the Massachusetts Audubon Society, the New England Forestry Foundation, and The Trustees of Reservations. Russ' foraging book, Wild Plants I Have Known...and Eaten, is now in its ninth printing. Russ has taken on the role of Johnny Appleseed for edible native species, collaborating with land trusts, cities and towns, and other groups (including one in Cambridge) to plant plants from his nursery in appropriate places on their properties.
