Impacts of a Stump Uprooting Operation on Properties of a Calcareous Loamy Soil and on Planted Seedling Performance
Resource
Six hundred Douglas-fir (Pseudotsuga menziesii) and 600 lodgepole pine (Pinus contorta var. latifolia) seedlings were planted on seven plots in a cutover north of Golden, British Columbia, to...
Impacts of Blading and Burning Site Preparation on Soil Properties and Site Productivity in the Sub-Boreal Spruce Zone of Central British Columbia
Resource
We investigated soil factors and tree growth on sites that were clearcut during the 1970s and early 1980s and were subsequently site prepared with either blade scarification (blading) or prescribed...
Impacts of Climate Change on Photosynthesis and Carbon Sequestration / Impactes des changements climatiques sur la photosythèse et le piégeage du carbone
Resource
Global warming may cause photosynthesis to start earlier. As the climate warms, spring arrives earlier and fall ends later. This change in temperature affects how trees grow. Gretta Goodine of the...
Impacts of Cross-Contour Skidroads on Properties of a Gravelly Sandy Loam Soil and on Planted Seedling Performance
Resource
Soil conditions, growth of 1200 planted seedlings each of lodgepole pine ( Pinus contorta var. latifolia) and Douglas-fir ( Pseudotsuga menziesii), and development of other vegetation were studied to...
Impacts of Different Methods of Mechanical Site Preparation on Foliar Nutrients of Planted White Spruce Seedlings
Resource
The impacts of different methods of mechanical site preparation (MSP) treatments on foliar nutrients of planted plug+ 1 white spruce seedlings were examined at two mixed-wood boreal forest sites (Judy...
Impacts of Major Pests on Forest Growth and Yield in the Prairie Provinces and the Northwest Territories: A Literature Review
Resource
Literature pertaining to the impact of forest pests on timber productivity in the prairie provinces and Northwest Territories is reviewed. The discussion of impact is largely confined to growth loss...
Impacts of Soil Disturbance on Roots Systems of Douglas-fir and Lodgepole Pine Seedlings

Influence of Forest Management Activities on Soil Organic Carbon Stocks: A Knowledge Synthesis
Resource
Almost half of the total organic carbon (C) in terrestrial ecosystems is stored in forest soils. By altering rates of input or release of C from soils, forest management activities can influence soil...
