Abstract
Smooth bromegrass (Bromus inermis Leys.), orchardgrass (Dactylis glomerata L.), alsike clover (Trifolium hybridum L.), and a mixture by mass of 40% orchardgrass, 40% alsike clover, and 20% white clover (Trifolium repens L.), were sown at 0.5, 1.5, 3.0, 6.0, and 12.0 kg/ha on a forest clear-cut in the southern interior of British Columbia. The seeding treatments were monitored for 3 growing seasons following planting to determine their influence on the growth, survival and damage of planted one-year old lodgepole pine (Pinus contorta var. latifolia Engelm.) seedlings. Competing vegetation reduced lodgepole pine diameter by up to 38% (P 0.05) among the treatments and controls, and conifer survival was independent (P > 0.05) of rodent damage.
