Summary: This licence has been issued for the scientific research application No. 5947. The aim is to monitor vegetation changes in current climate warming for simulating past and future dynamics with an individual-based spatially explicit model (LAVESI). Therefore, our intentions are: 1. assessing stand inventories at diverse bioclimatic and environmental settings by a space-for-time approach 2. gat...

Summary: The goal of this project is to determine arsenic toxicity in the environment through time by using trees and soils from the area surrounding the Giant Mine. This will be done using synchrotron techniques to determine the intensity of toxicity in each year since the contamination started. A 5.1 mm tree borer will be used to take 2 cores from trees within a close proximity to Giant Mine. The res...

Summary: This study is to monitor the environmental impacts of disturbances caused by the Canol Project and to measure the effects on permafrost of climate change. The Canol disturbance studies have been underway since the late 1970's and the permafrost studies since 1990. This is year 15 of a 20-year study. Access during the summer is via the Yukon along the Canol Road through Macmillan Pass. Beyond...

Principal Investigator: Nichol, Susan L.
Licensed Year(s): 2005
Summary: The objective is to improve knowledge about landslides in the Mackenzie Valley. The results of this study will enable better environmental impact assessments and help to reduce environmental impacts related to the construction and operation of the proposed Mackenzie Valley pipeline. As well, the results will have a broader application to a wide range of future development activities in the region....

Summary: The Gwich'in Renewable Resource Board (GRRB) is working with the Department of Resources, Wildlife and Economic Development (DRWED) and Gwich'in Tribal Council (GTC) to develop a forest management plan for the Gwich'in Settlement Area. In order to manage the forests sustainably, we must have a good understanding of how fast trees grow and how forests regenerate after disturbances (particularly wi...

Principal Investigator: Jacoby, Gordon C.
Licensed Year(s): 1994 1989
Summary: The researcher will take 5 mm diameter increment core samples from old-aged trees growing near the tree line. This sampling is not harmful to the trees. At two sites the researcher will sample about 10 trees. The samples are processed to produce ring-width and wood- density data for each annual ring. This data will then be statistically compared to meteorological data to make estimates of past cl...

Principal Investigator: Osawa, Akira
Licensed Year(s): 1994
Summary: The researcher will conduct research on jack pine forests along the highways in Wood Buffalo National Park and will also collect stem increment cores from black spruce trees around the latitudinal tree line near Inuvik. This research will consist of remeasurement of permanent plots, foliage distribution and light measurement, establishment of pruning experiment and stem core sampling near Inuvik....

Principal Investigator: MacDonald, Glen M
Licensed Year(s): 1989 1988
Summary: Dr. Glen MacDonald and his team will be obtaining lake sediment cores, samples of pine needles, cones, seeds and tree-ring cores from 2 sites near Hay River. Fossil pollen from the sediment will be used to document the chronology of pine migration into the NWT following the last ice-age. The study will be used to understand postglacial history of northern plants....

Principal Investigator: MacDonald, Glen M
Licensed Year(s): 1988
Summary: to obtain lake sediment cores, peat samples, and tree-ring cores in the Kazan river region to examine the postglacial history of the northern treeline in this region...
