Succession of Mount St. Helens: Eruption Impact and Recovery over Decades

This comprehensive overview examines the ecological succession following the May 18, 1980 eruption of Mount St. Helens. Visual documentation over several years showcases the recovery process, highlighting changes from immediate post-eruption landscapes through to 100 years later. Key stages of succession are illustrated, including the fascinating role of nitrogen-fixing lupines in soil enrichment. The timeline reflects a journey through various stages—months, years, and decades—of recovery, offering insights into the resilience of nature in the wake of volcanic devastation.
