The Polly Hill Arboretum in West Tisbury welcomes back Sheriff’s Meadow Foundation’s director of stewardship Kristen Fauteux and Martha’s Vineyard Land Bank ecologist Julie Russell, for an in-depth study of our island trees. Join them for this one and a half-day workshop to learn the tools of tree identification and to search for examples of island native trees in their habitats. We begin Wednesday with a class (9 – 3) at the Arboretum, then head into the field to find our trees. Thursday we continue our field exploration from 9 – noon. Class size is limited, advance registration required. $90/$70 for PHA members; $50 for professionals associated with Island land management or conservation organizations. To register, and for more information, call 508-693-9426.
