Marker 3This vast expanse of short-grass prairie, an area of historical and natural heritage, is endangered today. The surface area of this relic has been much reduced over the past few decades. While the summits are made stable by the prairie, the mountain side presents evidence of erosion (denuded rocks) that is the result of foresters’ attempts at reforestation. On the ledge, pines are starting to establish themselves at the expense of the prairie. These zones have become fragile and need better management of all the territory’s elements. Shepherds will have to guide their flocks carefully here, so as to avoid making erosion worse but also to eliminate pine seedlings.
