The vegetation of the Canadian Prairie Provinces IV. The woody vegetation, Part 1
In this paper the shrub communities of the dryland habitats are described. Dryland shrub communities usually form transitions between the various grasslands and woodlands. Well developed communities are shown to be closely related to similar communities of Eurasia, and can be placed with these communities in the class group Rubo-Rosea. One class, with two orders, four alliances, 14 associations, 12 subassociations and several variants and unclassified communities are recognized and described.
