Following the 1980 eruption of Mount St. Helens, nearly 10 million trees were planted across more than 14,000 acres of National Forest land, with survival exceeding 70%.
That ability to grow and regenerate is a big part of what makes the PNW such productive forestry country, creating an ongoing need for forest mulching, vegetation management, fuel reduction, and site preparation.
