Wisconsin's quaking aspens are growing much faster than in the past, and scientists think that rising levels of carbon dioxide in the atmosphere provide the explanation.
...With their white bark and fluttering leaves, quaking aspen are a dominant tree species in many forests. Thus, the Wisconsin and Minnesota scientists said trees' faster growth have both environmental and economic repercussions. Aspen are heavily used by the pulp and paper industry.
We're still looking for damages, or awfulness, or something.
But this doesn't mean unbridled growth, according to one of the authors, Donald M. Waller, a botanist at UW.That's because aspen grow slower and consume less carbon dioxide as they grow older, Waller said. It's also unclear how insects and pathogens will respond to faster growing trees in the future.
