So the Wilderness Society report is no big surprise to Mark Harmon, an Oregon State University professor of forest ecology, who has been studying carbon storage in forests for decades.
If anything, the results might underestimate the amount of carbon stored because the current science is better at estimating what’s held in live trees, than what’s in a forest’s soils and dead wood, which also store carbon, he said.
… “We knew where old growth habitat was,” Mike Anderson said. “We had a sense that the Northwest had a lot bigger trees and denser vegetation than other parts of the country. And the Willamette National Forest in particular has always been seen as an especially productive forest.”
