Query: Great for native trees and shrubs in the PNW

This was a great book that first used in college forestry classes. It uses sketches of the leaves rather than photos. The sketches emphasize the unique characteristics to look for on each leaf, whereas a photo doesn't really show the fine differences between the firs, for example. Grab it if you can find it. Someone stole my college copy from my work desk, I finalllyfound a used copy to replace it.
