The Rochester Land Trust is hosting a free “Wild Edibles” foraging walk Wednesday from 6 to 8 p.m. at the trust’s Church’s Field property on Mattapoisett Road. It will be led by Russ Cohen of Arlington, a professional environmentalist and wild-foods expert and author of “Wild Plants I Have Known . . . and Eaten.” Bunny Mogilnicki of the land trust said: “This is a first for us. We try to show the land we’ve saved, and when Russ became available, we thought ‘What a great way to show Church’s Field.’ ” She said the land has three distinct ecological habitats — open meadow, woods, and river. She said she’s not sure what participants will find under Cohen’s tutelage, “but I’m pretty sure there will be at least wild strawberries.” No registration is necessary. For information, contact Mogilnicki at 508-763-0088 or firstname.lastname@example.org. For information on Cohen, visit users.rcn.com/eatwild/bio.htm.
