mount st helens ecology

By Warren Cornwall May. Some did, but much of the regrowth can also be attributed to “biological legacies” — the fallen trees, buried seeds and amphibians that survived the blast and have been resilient restarters of the green spaces around … A central figure in this story, for instance, is Charlie Crisafulli, who has dedicated his career to studying this story of ecological regeneration. These new habitats were quickly colonized by a great diversity of aquatic life, such as amphibians, insects, plankton, and plants. This finding calls into question the necessity of dispersal corridors for connecting source populations with newly created habitat patches. Scientists predict that it will likely take hundreds of years before the area returns to a forest dominated by fir and hemlock trees. Research into the ecological responses to Mount St. Helens' 1980 eruption has fundamentally transformed not only understanding of volcanoes, but our ability to live alongside them. In the first few days after Mount St. Helens erupted—sending some 540 million tons of ash over an area of 22,000 square miles—the WSU ecology professor was already thinking of its potential research value. Summer Ecology Program is a multi-day field-based camp which exposes participants to research taking place today in the landscape affected by the 1980 eruption of Mount St. Helens. He started as an undergraduate when his mentor, Utah State University biology professor Jim MacMahon, included him in a team that came to the mountain in 1980 to study how small mammals responded to a volcanic eruption.
