This is a classic non fiction, informational text for those who are deeply intrigued and fond of trees. It includes a table of contents, six chapters, a glossary, a section offering more sources to find out more about trees, a list of sources, and an index. The book uses real pictures of tress so that the reader can more easily identify the trees if they were to see one in person. It is certainly for older students since it is text heavy but it's still a wonderful non fiction text.
