Abstract
The relationship between climate and tree-growth for loblolly pine in north Georgia is investigated by: 1) determining during which months climate has its strongest impact on loblolly pine growth, and 2) specifically examining the relationship between loblolly pine growth and growing season precipitation. Response function analyses indicate that precipitation during the current May-August period has a positive effect on pine growth, while the previous growing season shows no significant effect on growth. Significant negative effects of temperature were found during the previous June and August, current April, and the current June-September period. A regression model predicting the May-September growing season rainfall total as a function of tree-ring indices was highly significant (r2 = 0.48). These results indicate that loblolly pine is a useful species for investigating the impact of climate and other factors on the recent decline of pine growth in the southeastern United States.
