Abstract
Abstract Pollen assemblages from surface samples of lake bottom sediment and northern muskeg indicate that the major vegetation regions (boreal forest, taiga, forest‐tundra, and tundra) that extend from central Quebec to the eastern Arctic can be identified on the basis of palynological information. Although it is possible to recognize modern palynological tundra in relation to present distribution limits of vegetation, it should not be concluded that unqualified identification can be made of “palaeotundra” that presumably existed in the periglacial zone that bordered the southern margin of the continental ice sheet in late Pleistocene time. Our present data base is not adequate with respect to arctic palynological surface sample coverage and the understanding of atmospheric pollen dispersal over the northern regions. This information is required for the study of the history of tundra environment in the Cenozoic palynostratigraphic record.
