| Summary: | "The May 18, 1980, eruption of Mount St. Helens dramatically transformed forests, meadows, lakes, and streams within a vast portion of the Cascade Range in southern Washington. Within days, scientists were on the scene and have remained, documenting the process of ecosystem reassembly. The eruption created exemplary opportunities to learn how plants and animals initially respond to large, intense disturbance and the longer term process of succession. Findings from this work have advanced understanding of disturbance ecology and shifted thinking on how to manage landscapes after disturbance. For example, biological legacies--remnant woody structure and surviving organisms--were found to strongly influence the plant and animal communities that develop after the disturbance. This discovery contributed to changes in forest harvest policies, leading to the practice of leaving some live and dead trees within harvest areas. Key ecological lessons from Mount St. Helens and the process of doing long-term research have also yielded information that scientists with the Pacific Northwest Research Station are now sharing with others around the world."--Summary. |
