The region is strongly influenced by the large mountain ranges stretching throughout most of the coast. Changes in elevation cause changes in plant/animal diversity, this can be exemplified through observing the alpine tundra's vegetation which consists of shrubs, herbs, mosses, and lichens; while lower elevations, the temperate coastal forest hold magnificently large trees such as western ...
