(KTVZ) – Oregon wildfires threatened several communities late last summer, destroyed more than 4,000 homes, filled the air with thick smoke for days and burned more than 1 million acres, the second-highest one-year total in state history. Six months later, more than a dozen Oregon State University College of Forestry researchers are probing the blazes’ aftermath in a range of ways, including stream studies in several western and southern Oregon watersheds and a look at fire’s ramifications for biodiversity in a collection of southwestern Oregon forests.
