Annual production of canopy foliage and its subsequent senescence in autumn, coupled with flower, seed, and terminal-branch production and senescence are among the quintessential processes defining deciduous forests. The annual renewal of canopy foliage and the production of seed crops are energy-intensive processes requiring the formation of stem, leaf, and flower primordia in previous seasons, the storage of carbohydrate supplies, and the translocation and storage of nutrients (Kozlowski and Pallardy 1997). Litter collection data provide direct information about annual carbon inputs to the forest floor. They also are a primary set of measurements from which the maximum annual leaf area index can be derived. Prior to the initiation of this study, changing precipitation inputs were hypothesized to have various impacts on the production of foliage, flowers, seeds, and terminal branches based on potential changes in carbohydrate supply or available nutrients (Gholz et al. 1990).
