Summary: The proposed research program involves terrestrial studies in the Gwich'in Settlement Area to be conducted during 2002. Initial Vegetation investigations were conducted in summer 2001 to classify vegetation along the study corridor. This classification was essentially completed in the Gwich'in Settlement Area. Vegetation studies during 2002 will focus on locating areas of rare or uncommon plants...

Summary: The vegetation component of the 2002 baseline studies will focus on completion of the vegetation typing surveys. Initially, a reconnaissance flight will be required over Sahtu Private Lands along the study corridor. This flight will be used to identify sites for detailed sampling. Sites will be selected to represent the major ecological land units. Where possible, sample sites will be grouped to...

Licensed Year(s): 1998
Summary: This project will take place in Tuktuk Nogait National Park in 1998 and 1999. The objective of the project is to map the vegetation of the park. As many areas of the Park as possible will be hiked and the various vegetation communities along the hiking route will be put into one of several classes, and their exact geographical location recorded. Once the field season is over, these various geograp...

Principal Investigator: Witteman, John
Licensed Year(s): 1996 1995
Summary: As part of overall reclamation goals of BHP, the 1996 season will focus on three components. Vegetation response will be assessed in August using the point-frame method. Within the legume, indigenous seed and shrub cutting plots, plant density will be recorded. Soil samples in replicates of three will be collected from each treatment to analyze physical and chemical characteristics. Secondly, ...

Licensed Year(s): 2000 1999 1998 1997 1996 1995 1994 1993 1992 1990
Summary: The research is planned to see what happens after the surface of the land was changed by clearing of the trees and trenching of the soil in 1985 and 1986, and the spilling of crude-oil in 1988. Ways to fix or lessen these disturbances are being tested to see which are best. Many studies will be done, including measurement of air and soil temperatures, wind speed, moisture, water movement, permaf...

Principal Investigator: Henry, Greg H R
Licensed Year(s): 1995 1994 1993 1991
Summary: The researchers want to determine the age of the isolated "tree islands" and how they manage to grow so far from the treeline. Researchers look for old stems for carbon dating, and map the position of each stem. The age and growth rates of the trees are determined by counting and measuring tree-rings. This year plant communities found on south-facing slopes down the Anderson River will be studied....

Licensed Year(s): 1993 1992
Summary: 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...

Principal Investigator: Svoboda, Josef
Licensed Year(s): 1994 1993 1992 1991 1988 1987
Summary: The researcher and his team will learn how plants returned to the arctic realm after the retreat of the continental ice sheet some 8000 years ago, and what the prospect is for the present polar deserts to become green again if the climate ameliorates, as predicted. As well, they will investigate the effects of climate warming on tundra plant communities in the Mid-arctic, through the simulation of...

Principal Investigator: Wein, Ross
Licensed Year(s): 1993 1992 1989 1988 1987
Summary: In the early 1970's, several test plots were established to see what happens when the plants and soil are disturbed or removed by fire, oil spills, and vehicles. Dr. Wein and two students will be re-visiting these sites to document how the plants have recovered since that time....

Principal Investigator: Kershaw, G. Peter
Licensed Year(s): 1989 1988 1987
Summary: Over the past several years, Dr. Kershaw has been trying to find out the best way to make the plants grow back after they have been removed to build a pipeline. He is also looking at ways to keep permafrost areas from melting if the insulating plant cover is removed....
