In this episode of the Perpetual Notion Machine, PNM’s hunter/gatherer Lincoln Tice explores the search for wild edibles, or in other words, foraging. With a little bit of education, anyone can find edible plants and fruits right from their own backyard or neighborhood. Lincoln’s guest is Kelly Schwartz, who just happens to also be a PNM volunteer. Despite her advanced expertise in microbiology, she has extensive experience in foraging and wild edibles from an early age. She passes along a few general rules people need to know while they’re foraging. The most obvious one is to know the plants, be able to identify them, particularly the ones that are edible from the ones that aren’t. Kelly explains a few of the plants that are poisonous. Also, don’t take too many plants from that location. Be cognizant of the ecosystem where you are foraging. And Kelly mentions that the UW Arboretum is a good place for beginners to learn about foraging. However, harvesting edible plants and fruits in the Arboretum is forbidden.
