Approximate Total Miles

This one has “hairy arm pits” while that one is covered in oak apple galls. There’s a couple with lobed leaves, and some others with spiny leaves, while some are deciduous and others are evergreen. Help! It’s time to learn your local, native California oak trees with Docent Naturalists Frances Reneau and Helena Cohen on this leisurely-paced hike. With any luck, many will also be fruiting and covered with nutritious acorns, a mainstay in the diets of many local omnivores, including humans. Homemade acorn bread provided!
