Résumé: The project will examine past tree growth patterns at the northern treeline in Western Canada as a baseline to predict future growth responses to climate change. Additionally, the researchers will examine tree regeneration and plant associations at the northern treeline. Annual tree rings represent a growth response to local climate. Wide growth rings represent good growing conditions, and nar...

Résumé: The objective of this study is to develop a landscape model capable of predicting regeneration after fire in the Northern Boreal Forest. Data has been collected in the past from Porter Lake (near Lutsel K'e), Big Fish Lake, Alberta, and Wood Buffalo National Park, between Pine Lake and Peace Point. Data has also been collected from the International Crown Fire Modeling Experiment near Fort Pro...

Résumé: Caribou populations fluctuate over long time spans, however, long-term records of population cycles are scarce. The population dynamics of the Bathurst caribou herd across the Northwest Territories will be reconstructed using two proxy indicators of cli...

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...

Résumé: The study area will be sampled on a 2x2 km grid as the vegetation type of the area in question is predominantly jack pine. At each 2 km interval 3 procedures are done: 1) plant identification and % cover of each species in approx. 100 m. sq., 2) tally of the fuels (logs, twigs, branches) that fall along a triangular transect, 3) discs are removed from one large unscarred tree and one scarred tree...

Résumé: As a result of global warming (which results from increased amounts of carbon dioxide in the atmosphere), it is suggested that the number of forest fires and the amount of area burned may increase in the northern boreal forests. The types of trees that grow first in these burned areas may be different from those that would have grown in if the climate was cooler. I will collect data at burn site...
