Following Hydro-Quebec's decision not to proceed with a hydroelectrical project near the Hudson Bay, it was further decided to improve the bare site of the exploration camp and to restore it to its original state by planting green plants that harmonize with he local vegetation.
Therefore, when formulating a method for restoring the area to its natural state, we sought the most economic technique and took into consideration the characteristics of the terrain.
The first step was to determine the kind of plants that could be introduced at such a location. A review of the exisiting literature and an inventory of the local vegetation led us to the conclusion that sea lyme grass (Elymus arenarius) would be the best plant for restoring the terrain to its natural condition. The technique selected for our work on the site was transplantation which we felt was the most suitable and effective method for a northern environment. Plants growing in a similar environment were dug up and replanted in the area to be restored, using the following three types of replanting: the replanting of clods, of individual plants and of clumps or tufts.
The transplantation was carried out in Summer 1983 and assessment of the results was made during the Summers of 1984 and 1985. The operation seems to have been highly successful with more than 95% of the plants surviving transplantation. Examination of individual plants showed excellent development of the root systems and, in several cases, propagation by the rhizomes had begun.
This experience enables us to envisage the improvement of other disturbed areas in the north. For example, there are frequent problems with unstable sand near native villages. Although different plant species might be introduced, depending on the constituents of the environment, the principal replanting
techniques could nevertheless be used.
