Abstract

The greenhouse gases CO₂ and 0₃ are increasing in the earth's atmosphere. Little is known about long-term impacts of these two co-occurring gases on forest trees. We have been examining the impacts of these two gases on the physiology and growth of trembling aspen (Populus tremuloides) and sugar maple (Acer saccharum) in an open-air exposure system in northern Wisconsin, USA for the past 5 years.

Keywords
