Abstract
  • The study evaluates the use of Competitive Stress Index (CSI) as a quantitative measure of stand density in a young-growth Douglas-fir stand in Western Oregon which had been subjected to various thinning regimes. Operational applications of the index are examined and new methodologies presented for the analysis of tree and stand growth response following thinning. Field procedures for sampling for competitive stress are outlined and the derivations of various sampling estimators are given. An index for predicting regular suppression mortality is derived and tested under natural stand density conditions. Results of the study indicate CSI is a viable expression of stand density and has tremendous potential as a management tool.
