This book has become an invaluable reference material for me as I restore habitat at the state park where I work. Easy for a beginner to understand but still great for a more experienced native gardener.
This particular book I find myself referring to all the time. Truly an invaluable resource.
Here's a description from this site- http://seattlepi.nwsource.com/nwgardens/84582_gardenbook29.shtml
"A comprehensive reference guide to more than 1,000 woody plants that are native to North America. More than just creating an encyclopedia of plant material, the author includes tips on how to attract particular birds and butterflies by using trees and shrubs. Feeding the birds the natural way is much more practical than spilling seeds all over the garden trying to refill a feeder. Another practical section is on where to find the right native plants for any type of garden and how to restore natural habitats by using native woody plants. A nice investment for both plant and nature lovers."
