Most of the weeds found in pastures and along roadsides thrive on gravel slides. Of the herbaceous plants, the grasses, particularly Dan- thonia spicata, commonly play an essential role, contributing to bring about increased stability in the substratum through the formation of a more or less continuous sod. Shrubs, notably Rttbus idacus canadensis, and trees, especially the white spinice, are also important in this Figure 15.—Gypsu

Sometimes a xerophytic weed stage in the succession, in which the plants are scattered and the vegetation open, is followed by a definite grass stage, in which the ground is completely carpeted by vegetation. But more commonly trees are present from the outset, and the first continuous plant cover is dominated by trees,. which form an open grove, the ground between the trees being grassed over or else occupied by colonial herbaceous species, such as Dicksonia and Anaphalis, or by Ruhus. The white spruce invariably stands preeminent among the trees, but there is a scattered representation of balsam fir, paper birch, balsam poplar^.
