The Dartmouth Natural Resources Trust is hosting its yearly online auction now, which will stay open until Aug. 30 at 9 p.m.

Items range from artwork to gift cards to sports tickets to ceramics lessons. Buy four tickets in the Red Sox Owner’s Dugout, a handmade knit scarf or a one-night stay in a treehouse. 

All auction items can be viewed at DNRT’s office at Helfand Farm, from 8:30 a.m. to 4:30 p.m. Viewings outside these hours can also be arranged by emailing kendra@dnrt.org.
