Pacific Coast forest The densest and most majestic coniferous forest in the world, extending from the north of California to the south of British Columbia. It is famed for its giant trees, the best known being Sequoia sempervirens (coastal redwood), Sequoiadendron giganteum (big tree), and Pseudotsuga taxifolia (Douglas fir). All may exceed 100 m in height and even 110 m in the case of the big tree, and the girths of certain redwoods are often greater than 20m.
