Ever baked with acorn flour or eaten a roasted bay nut? Wild foods are everywhere if you know what to look for. In the Abundance of Fall Edibles online class, naturalist and California School of Herbal Studies instructor Autumn Summers will teach teens and adults how to identify as well as ethically and sustainably harvest these foods. She’ll also share recipes and nutritional information, and discuss how eating wild foods can help one better understand and connect to the diversity of the local ecosystem. Pepperwood Preserve will host the Zoom class, which is suitable for ages 13 and older (younger kids must be supervised by an adult), on September 22, 7–8:30 p.m., for a suggested donation of $10.
