Pacific Northwest forests are renowned for their giant conifers, lush understory, and quiet majesty. There are more conifer species in our forests than almost anywhere else and the trees in the Northwest are among the largest found anywhere on earth. While the number of deciduous tree species is less than other parts of North America the ones we have provide interest and contrast to the evergreens.

Mark is currently photographing approximately 600 species of northwest trees and shrubs for a new field guide due to be published by Timber Press in 2014.
