Mixed-species forest stands are generally thought to be more productive than single-species stands. However, empirical evidence is lacking. We tested the effects of species mixture on productivity based on variable compositions of western hemlock (Ts

Stand volumes were determined for naturally established, even-aged, single- and mixed-species stands involving three combinations of shade-tolerant and shade-intolerant conifers on similar sites: (i) western redcedar western hemlock (Thuja plicata

Root structure of western hemlock (Tsuga heterophylla (Raf.) Sarg.) and western redcedar (Thuja plicata Donn. ex D. Don) was studied in single- and mixed-species stands of hemlock and western redcedar in Capilano River watershed, University of Britis

Black spruce (Picea mariana (Mill.) B.S.P.) is a boreal species that occurs extensively across the northern half of British Columbia. Forest managers require better growth and yield information for black spruce given the anticipated increase in deman

British Columbia's foresters currently use height growth curves developed with data from Montana to estimate the height and productivity of western larch (Larix occidentalis). The ability of the presently used curves to accurately predict the height

To evaluate the variation in trembling aspen (Populus tremuloides Michx.) productivity at a large geographic scale, we examined the relationships between site index and environmental factors from 142 even-aged, fully stocked stands located on a varie

We described quantitatively the height distributions of three high-elevation, old-growth stands in the Engelmann Spruce Subalpine Fir zone of west-central British Columbia. The stands were composed of subalpine fir (Abies lasiocarpa (Hook.) Nutt.)

To quantify the gradient of plant-available nutrients on high-elevation coastal sites that support growth of Pacific silver fir ( Abies amabilis (Dougl. ex Loud.) Forbes) in southern British Columbia, we collected samples of forest floor and mineral
