North Pacific Volcanic Rock and Cinder Land

This ecological system includes barren and sparsely vegetated volcanic lava flows, cinders, ash beds and volcanic boulderfields created by the active volcanoes occurring throughout the Cascade Mountains in the Pacific Northwest. These are not vegetated, or have vegetation limited to a few small openings. Due to the active nature of many of the northwest volcanoes, these range from small patches around older volcanoes, such as Mount Jefferson, and large barren areas around active volcanoes such as Mount St. Helens.
