MOUNT RAINIER Features of the Flora of Mount Rainier National Park

In a general treatment of the flora of Mount Rainier National Park we must bear in mind the fact that the mountain is located near the center of the park and that the park extends down into the dense forest, thus giving a varied and extensive flora.

For convenience the park may be divided into five zones:

1. The lower area near the boundary, between elevations of 2,000 and 2,800 feet, is composed of wide river valleys covered with large trees around which are woven masses of moss, liverworts, lichens, and ferns. These plants also form a beautiful cover for the forest floor.

2. The upper forest region between elevations of 2,800 and 4,000 feet is characterized by trees covered with gray hanging forms of lichens, smaller trees, and a gradual transition to alpine types.

3. Between 4,000 and 5,500 feet trees are found in groups distinctly alpine alternating with grassy meadows.

4. From 5,500 feet to timber line.

5. Rocky ridges and pumice fields above timber line.
