Though best known for his superlative bird guides, David Allen Sibley is also a lifelong tree spotter, and here he applies his formidable skills of identification and illustration to the trees of North America. With more than 4,100 meticulous, exquisitely detailed paintings, his guide condenses a huge amount of information into a logical, accessible format, highlighting the often subtle similarities and distinctions between more than 600 tree species, both native and introduced.

"A beautiful, masterful, and much-needed work that will henceforth be our guide to the North American trees."—Edward O. Wilson
