timber management strategy design tool. Long-range timber management
modelling systems were identified as being limited by the inability to
perform large-scale ...
Econometric model of Canada's newsprint exports to the United States of America

This study was the -first study designed specifically to
analyse the competitive effects of density and species mixture
for both Pinus banksiana and Populus tremuloides
