The information contained in annual tree rings is a valuable resource for studying environmental change. Past climate can be reconstructed from the yearto-year changes in annual ring width and ring density (e.g., Fritts, 1976; Schweingruber et al., 1978). The occurrence of previously unrecorded geomorphological events, such as earthquakes and landslides, can be inferred from anomalous changes in the ringwidth pattern (e.g., Shroder, 1980; Jacoby and Ulan, 1983). Foreststand disturbances and gapphase dynamics can be inferred from suppressionrelease patterns in tree rings (Brubaker, 1987), and, anomalous changes in the forest environment, due perhaps to anthropogenic pollutants, can be examined based on the recent patterns of tree rings (e.g., Eckstein et al., 1983, 1984; Cook, 1987a). This list of applications is not complete. It is only intended to show that tree rings can be used to study a variety of environmental changes.
