Preserving native plants by using them is the topic of a June 8 presentation with Arthur Haines at the Polly Hill Arboretum. Mr. Haines is a plant taxonomist, author and teacher who makes the case for preservation of native plants through foraging, wildcrafting and medicinal use. He argues that the waning use of wild plants coincides with a decline in our health and of the local landscape.

Mr. Haines’ talk is from 1 to 2:30 p.m. at Polly Hill, 809 State Road in West Tisbury.

Cost is $20 or $10 for arboretum members. Call 508-693-9426 for more information.
