Objectives of the field work are two-fold: one is to collect data in jack pine and in lesser extent black spruce forests on annual movement of organic matter and carbon; the other is to continue the study of stand development and its relationship to environmental factors (a discipline called ‘silvichronology’). For the former objective, the research team will continue measurement of the growth of ...

Résumé:
Objectives of the research are two-fold. First is to estimate structure and growth of forest stands in northwestern Canada by applying a stand reconstruction technique. Second is to examine the relationship between climate change in the Arctic region and the patterns of forest biomass growth during the past century. The research team also measure currently occurring growth and carbon dynamics of f...

200320022001 Résumé:
Northern forests are closely connected to the issue of global warming because they are likely to absorb much of the carbon dioxide that is emitted into the air by humans. The amount that these forests absorb, however, is not clear. The research team will...

Résumé:
A network of permanent monitoring plots (PMPs) is required for assessing forest growth and yield in the NWT. These PMPs will be used to: 1) obtain information to assess the rate of forest growth and determine current and potential yield of various fores...

Résumé:
The main objective of the proposed research is to collect extensive data of tree size and stand density from mixed forests of Jack pine and quaking aspen in Wood Buffalo National Park and to examine theoretically the patterns of quantitative forest development with special reference to the phenomenon of 'natural thinning' in even-aged forests. The research team consisting of forest ecologists will...

1997 Résumé:
The research team will consist of forest ecologists. We plan to study a few jack pine stands by taking stem samples for examination of forest growth that occurred in the past. A possible effect of climate change on the growth of forests are being examined. Several trees were cut and were analyzed last year. This summer several additional stems will be sampled. When a tree is cut, we try not to dis...
