Hidden in plain sight, along city streets and in parks, are trees with a special natural history. For example: the Ginkgo is evolutionarily unique, and both the American Chestnut and American Elm are survivors of diseases that devastated their species. Sadly, every day, many people walk by unique trees such as these and do not know how special they are. We share them so you can know them by name and sight, tell others about them, and protect them. This book identifies 10 unique tree species. Tree identification strategies as well as lots of pictures of leaves, seeds and bark, accompany interesting facts. Enjoy.
