I have a favorite tree book. A GOLDEN GUIDE: TREES. was actually the tree book I used in seventh grade when I created my tree scrapbook. This book is a pocket guide which contains common species. Since I'm not a tree expert I don't need or care for a thorough guide. The best thing about A Golden Guide: Trees, is that it breaks trees down into seven categories, and explains how to recognize trees in each category.
Needle-Like or Scaly Leaves - Conifers
Simple Leaves - Edges of leaves neither toothed nor lobed
Simple Leaves - Edges of leaves toothed
Simple Leaves - Edges lobed and toothed - Fruit is an Acorn
Simple Leaves - Edges lobed and toothed - Fruit is not an Acorn
Leaflets - Feather-Like
Leaflets - Finger-Like
Birch trees tend to have white or light colored bark, the flowers look like caterpillars, the simple leaves are toothed and turn yellow in the fall and they are related to Aspen trees which can be found all over Colorado.
