The Ozarks lie in what is nominally the oak-hickory forest zone, and witness trees studies show that oaks composed about 70% of the early historic forest when first encountered by land surveyors. This book presents oak ecology from a caterpillar’s point of view through the eyes of a veteran bug scientist, and there’s a lot going on behind the scenes.
