Now Wessels takes that wonderful ability to discern much of the history of the forest from visual clues and boils it all down to a manageable field guide that you can take out to the woods and use to start playing forest detective yourself. Wessels has created a key--a fascinating series of either/or questions--to guide you through the process of analyzing what you see. You'll feel like a woodland Sherlock Holmes. No walk in the woods will ever be the same.
