Comparison of Western Redcedar and Yellow-Cedar Growth Under Different Silvicultural Systems

This document summarizes the findings of the Montane Alternative Silvicultural Systems study, detailing a long-term comparison of how different harvesting techniques affect the survival and growth of western redcedar and yellow cedar. The study contrasted methods such as clearcut, shelterwood, and various retention systems over a 28-year period to assess key metrics like height and volume at the 25-year mark. The conclusions revealed that the silvicultural system profoundly impacts growth rates, showing that western redcedar grew fastest in clearcuts while yellow cedar achieved greater volume and height in the shaded shelterwood environments. This indicates distinct species preferences regarding light exposure following logging.
