Science Articles on Forest Silviculture in British Columbia

Removing Sitka alder and herbs from cutblocks when planting lodgepole pine may do more harm than good to the crop trees.

The hot, dry forests of southern BC's Interior Douglas-fir biogeoclimatic zone are difficult to regenerate after partial retention harvesting.

Seed from lodgepole pine trees in southern British Columbia produces faster-growing trees in many other areas of the province than does local seed.

Densely growing lodgepole pines readily form root grafts with nearby pines at any early age.

Many tree seedlings planted close to timberline in clearings smaller than 0.1 ha don't survive, and those that do live grow very slowly.

Planting trees without site preparation will end up costing the province of British Columbia considerably in future timber production.

Douglas-fir seedlings growing near old-growth patches benefit by acquiring more ectomycorrhizal fungi.

Observations have failed to reveal whether ageing or increasing height enables lodgepole pine trees to resist infection from western gall rust.

In young lodgepole pine plantations of central British Columbia, Warren root collar weevils attacked anywhere from 10 to 45% of saplings.

The body of research into the pros and cons of growing conifers among broadleaf trees in British Columbia's Interior Cedar Hemlock biogeoclimatic zone leads scientists to advocate for a new approach to regenerating forests.

Nearly two-thirds of planted lodgepole pines have severely deformed roots, compared with 9% of naturally regenerated pines, finds a study near Prince George in central British Columbia.
