Estimated emissions from Parks Canada for 1989 to 1991 exceeded this same trajectory by 4.4% to 17.7%. Despite commitments to ecosystem management approaches, there is little evidence that atmospheric considerations have been fully i

When designing forest machinery for transportation of timber the payload itself is the most complicated problem.
