Ancient forests tend to provide moderate temperatures compared with their surroundings, potentially buffering some of the sharpest impacts of climate change, said Matthew Betts, a professor at Oregon State University.

“In Coast Range and Western Cascades catchments, where our study streams were located, streams that are small and non-fish bearing have no regulatory requirement for an overstory riparian buffer,” said Kevin Bladon, lead author and assistant professor in the College of Forestry at Oregon State Un

“Imagine the difference between the temperature of the sand and the air at the beach on a hot, summer day,” said David Mildrexler, the lead author who received his Ph.D. from the College of Forestry at Oregon State last June.
