Effects of planting quality, depth and medium on growth and survival of lodgepole pine (Pinus contorta) in south central British Columbia Albrecher, Stefan A.
Abstract
Tree-planting quality, depth, and medium can significantly affect seedling growth, vigour, and survival in the Very Dry, Cool Montane spruce Biogeoclimatic subsone (MSxk). In this study, lodgepole pine (Pinus contorta) seedlings were planted in seven different treatment units to test for difference in growth and mortality. Trees were planted in F-layer, mineral soil, and poor medium, with damaged plugs, J-rooted, deep, and shallow treatments to test for these differences. All trees were measured two growing seasons after planting for nursery year growth (year 1 growth), second year growth, third year growth, caliper and mortality. Trees planted in the F-layer and mineral soil had significantly greater caliper than shallow planted seedlings which correlated strongly with third year growth, and survival. Third year seedling growth was significantly greater in F-layer, mineral screefs, and deep treatments. Mortality was greatest in shallow, poor medium and damaged root treatments and was likely caused by moisture deficit and drought. Total height differences were not found to be significantly different between treatments.
