It has been suggested that planting trees could help slow the buildup of carbon dioxide in the atmosphere. Since elevated levels of CO{sub 2} are known to enhance photosynthesis and growth in many plants, it is possible that trees could become progressively more effective in storing carbon as atmospheric CO{sub 2} increases. However, early results from experiments with ponderosa and loblolly pines indicate that the relationship between tree growth and rising CO{sub 2} concentrations may be more complex than scientists once thought. In these experiments, the response to elevated CO{sub 2} has been highly dependent both on species and on mineral nutrient levels in the soil. Further work is necessary to clarify the mechanisms involved. This research will ultimately contribute to an integrated model for predicting forest ecosystem response to elevated CO{sub 2}.
