By looking at small, specialized habitats, this series brings to life the multiple complexities present in even the most common or simple environments. For instance, a young reader will see the wealth of life that makes its home in a Saguaro cactus and learn of the richness of the life cycles of this familiar desert plant. Each book in the series presents an engaging life story with a wealth of additional information added in detailed sidebars.

This book examines the multitude of roles the Douglas Fir plays in its ecosystem, and the gaping hole it leaves when it is cut down.
