With a vertical relief of approximately 5,000 feet, Lassen demonstrants classic montane- to- alpine ecological zonation. Climatic variables such as temperature, precipitation, and snowpack duration change predictable with elevation, resutting in distinct life zone s each characterized by unique vestiation and animal communities.
