Abstract or Summary
  • The succession of plants over a period of 25 years was analyzed on clearcut areas in the western Cascades of Washington and Oregon. Thirty-three paired burned and unburned plots were reexamined in 1975. Data were combined with records from prior examinations by Morris (1970). Cover trends of six major brush species and five major herbaceous species were studied. Long term differences in plant succession between burned and unburned sites were identified. Total brush and herbaceous cover trends were similar on burned and unburned sites. Total herbaceous cover peaked approximately 14 years following logging and declined rapidly in subsequent years. Total brush cover steadily increased during the 25 year period. Increases in total brush cover were most rapid during the initial 14 years following logging. Ceanothus velutinus cover and occurrence was greater on burned plots while Rhododendron macrophylluni, Acer circinatum, and Gaultheria shallon had greater cover and occurrence on unburned plots. Greater cover of residual species on unburned sites was an important factor accounting for differences in successional trends. Variability between different plot pairs limited analyses which could be made. Results indicated secondary succession in the western Cascades varies greatly with elevation and between geographic localities.
