 The main species of trees within it are the golden birch, balsam fir, white spruce, red spruce and the cedar, as well as rarer quaking apens, paper birches, balsam poplars and mountain maple.However, a more profound analysis of the composition of the forests of Bas-Saint-Laurent allows to shed light on which trees grow at which elevations, type of soils and latitudes.Miroslav Grandtner categorized the south west end of the region, the littoral stripe before Rivère-du-Loup and the medium plateau in the golden birch forest, the high plateau as part of the paper birch forest, and finally, the Chic-Choc Mountains as part of the white spruce forest.
