Résumé:
Vegetation communities along the pipeline route and over other parts of the Project area would be provisionally mapped from aerial photographs. A field survey would be undertaken with an emphasis on identifying rare plants. The study area is in the Caribou Hills IBP site 4-9, which was in part proposed because of its rare flora. July is an optimum time for a single survey. Also transect sampling ...

Access to the site will be along existing seismic lines from Tulita. Transport will involve helicopter, boat, ATV and foot. The research is planned to see what happens after the fire to the permafrost, soils, plants and animals. An unburned site will be monitored to provide comparison with the burned area. Many studies will be done, including measurements of air and soil temperatures, wind spe...

1992 Résumé:
The researchers will investigate the effect that sea ice has on shaping and scouring the sea bottom since these actions may play a major role in determining the sea bottom environment and the types of plants and animals that may live there. They will revisit the 1992 site in order to determine what new scours have appeared: those locations with fresh scrapes on the bottom will be monitored over t...

198919881987 Résumé:
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 ...
