Yes, this study shows that the VOC's are a result of tree farms. Man
has altered the mix of trees in the landscape.

Again, altering the the mix of trees, harvesting pines and maples, and
letting oaks flourish.

This gem deals with only the aspect of trees emitting the gases that
react with tailpipe emissions (smog). If there was no smog, this would
