Scientists will describe some of the lessons learned from the eruption on April 18 during the second in a series of three Monday evening seminars to be held at Washington State University Vancouver. The seminar will start at 7 p.m. in
The seminar will feature two scientists with the United States Forest Service. Peter Frenzen, a scientist and public affairs officer, will give a presentation entitled “Out of the Ash: Survival and Recolonization in a Volcanic Landscape.” Charlie Crisafulli, a research ecologist, will speak on the topic “
Frenzen, who earned a master’s degree in forest ecology from
He will discuss the profound and sometimes subtle landscape changes revealed through repeat photographs taken before, just following and during the years following the 1980 eruption and how the volcano offers an opportunity to experience nature’s unbridled power and the wonder of its continuing cycle of cataclysm and renewal.
Crisafulli, who earned an associate’s degree from the State University of New York and holds a bachelor’s degree from Utah State University, where he has also been involved in graduate coursework, has been studying the ecology of plants, animals and fungi in the Mount St. Helens volcanic landscape and in adjacent old-growth forests for nearly 25 years.
He will discuss how the 1980 eruption killed or dramatically altered the types and numbers of animals that had been present before the eruption. Over the following quarter century, aquatic and terrestrial animals have undergone a remarkable recovery as individuals of hundreds of species expanded from surviving populations or invaded the new landscape from distant source populations. By 2005, most vertebrates and thousands of invertebrates had successfully colonized the disturbed area.
