Improving Douglas-fir Survival and Growth by Planting under a Stand of Juvenile Lodgepole Pine
Extension Note EN06

Introduction

Douglas-fir is the dominant climax species in the Interior Douglas-fir (IDF) subzone, and forests are highly-valued for a multiple of resource uses, such as timber, range, recreation, aesthetics and wildlife habitat. As a moderately shade tolerant species in the IDF subzones, Douglas-fir does not grow well in open conditions - clearcuts or old wildfires - where there is increased light, diurnal extremes in air temperature, and frequent summer drought. Summer frost is the major limiting factor to acceptable survival and growth of fir on these IDF sites. On moister sites in the ICH and SBS subzones, fir is a productive seral species with less need for shade.
