The next zone of the park is from 3,500 to 5,000 feet (1,066-1,524 meters) and has mixed forests of western white pine, western hemlock, and Pacific silver fir. Weather, food sources, migration, and breeding season affects the timing and species of birds found in this zone. The subalpine elevation zone extends from 5,000 to 6,500 feet (1,524-1,981 meters) and is where Paradise and Sunrise are located. This zone transitions away from forested terrain into subalpine meadows. Clumps of mixed forest remain among the meadows, made up of primarily subalpine fir, mountain hemlock, Alaska yellow cedar, and white bark pine. There are many birds found here, especially in the summer when the meadows are lush with wildflowers, seeds, and insects.
