Forests hammered by windstorms, avalanches, and wildfires may appear blighted, but a Washington State University researcher says such disturbances can be key to maximizing an area’s biological diversity.

In fact, says Mark Swanson, land managers can alter their practices to enhance such diversity, creating areas with a wide variety of species, including rare and endangered plants and animals.

“The 1980 eruption of Mount St. Helens, for example, has created very diverse post-eruption conditions, and has some of the highest plant and animal diversity in the western Cascades range,” says Mark Swanson, an assistant professor of landscape ecology and silviculture in Washington State University’s School of the Environment.

Swanson, who has studied disturbed areas on Mount St. Helens and around western North America, presents his findings this week at the national convention of the Ecological Society of America in Portland. » More …
