The northern village of Whapmagoostui is situated on deltaic sands that are easily mobilized by the wind. The instability of the substrate is further aggravated by human activities, particularly the development of a dense network of all-terrain vehicle trails. The community is becoming more and more aware of the progressive degradation of the vegetation cover and wish to solve the problem with a vegetation restoration program along with trail management in order to minimize the impacts of vehicular traffic on the environment. Measures permitting an accelerated regeneration of the natural vegetation should be recommended. Knowledge of the natural ecological succession process is necessary to install protection measures aimed at restoring these disturbed environments. The three principal objectives of this project are to: i. determine the influence of Leymus mollis on the performance of other herbaceous species selected for restoration projects, ii. determine the spatial variation in the distribution of species on the coastal dunes as a function of distance from the shore and to compare these with the distribution of species in the village, and iii. determine the social factors influencing the social acceptance of restoration projects of this type.
