Publisher's Synopsis
Excerpt from Extended Rotations and Culmination Age of Coast Douglas-Fir: Old Studies Speak to Current Issues
Curtis (1994b) compares estimates for selected management regimes produced by a number of widely used stand simulators. Although there are considerable differences among simulators, results indicate culmination ages considerably greater than the 40 to 50-year rotations now common in many ownerships, and suggest little change in production rates for an undetermined but considerable number of years beyond culmination.
This report presents additional evidence from examination of actual growth trends observed in existing long-term thinning studies.
