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, ...

Principal Investigator: Svoboda, Josef
Licensed Year(s): 1994 1993 1992 1991 1988 1987
Summary: The aim of the Sverdrup Pass Project is to learn how vegetation returned to the artic realm after the retreat of the continental ice sheet (8000 years ago) and the prospect of the land becoming green if climate warms. The Itex project is geared to the effect of climate warming on the vegetation. The snow-fence study at Baker Lake is concerned with the effects of long-lying snow deposited on both s...

Principal Investigator: Wein, Ross
Licensed Year(s): 1993 1992 1989 1988 1987
Summary: The research will document long-term recovery rates on permanent research plots that were established on a range of tundra disturbances. In the 1970's disturbance surveys and experiments on a wide range of topics provided short-term results and predictions on recovery rates. This project will collect comparable data to validate these short term predictions and will also help to develop some ideas ...

Principal Investigator: Forbes, Bruce C.
Licensed Year(s): 1990 1988
Summary: Bruce Forbes is looking at how quickly plants are invading the old settlement of Clyde River where the ground was cleared for buildings and roads. This site will be compared to undisturbed ground and similar disburbances at other human occupancy sites within the High Arctic....

Principal Investigator: Howland, William G.
Licensed Year(s): 1987
Summary: To continue the study of plants and landforms, including areas of landslide, in the Caribou Hills. To examine the plants that have revegetated, to observe what species seem most capable of natural revegetation and how much erosion or plant growth has developed in 10 years. To prepare a species list for plants near the East Channel....

Principal Investigator: Kabzems, Richard
Licensed Year(s): 1980
Summary: To describe the present condition and measure the vegetation cover of several revegetaion trails undertaken during 1976 & 1977....

Principal Investigator: Vaartnou, H.
Licensed Year(s): 1979
Summary: To establish test plots of various species of grass to determine the best types to be used to revegetate sites disturbed by pipeline construction....

Principal Investigator: Bouckhout, Leo W.
Licensed Year(s): 1978
Summary: (1) To survey native grasses, legumes and shrubs and evaluate their usefulness for revegetating disturbed areas. (2) To conduct fish counts, collect water samples for chemical data determination and prepare descriptions of all water crossings....

Principal Investigator: Hutchinson, Tom
Licensed Year(s): 1977
Summary: To determine the degree of recovery of crude oil spills made in 1972 and 1973 on taiga at Norman Wells and tundra at Tuktoyaktuk. To determine the effects of a 1975 diesel oil spill on taiga at Norman Wells and to compare the effects with crude oil spills made in comparable terrain. To examine the pattern of vegetational recovery of these areas. To examine the effects of crude oil spills made o...

Principal Investigator: Hutchinson, Tom
Licensed Year(s): 1977
Summary: To develop a practical and economic method of revegetation of "difficult" tailings and mine sites in the N.W.T., using acid and metal tolerant vegetation growing naturally at the highly stressed Smoking Hills area of Cape Bathurst, N.W.T....
