The dominant Lowland flora and the immigration of nearly 70% of Lowland species are the product of a gradual migration of species into the Lowland from extraglacial areas east, south, southwest, and northwest of the Lowland. [...] The weight of this water was, however, much less than the weight of the earlier ice sheet, and in consequence, the Lowland experiences the continent’s maximum rates of iso- static rebound, and hence, emergence of land from the ocean. [...] The frequency, separation, and heights of these beach ridges vary along the length of the Hudson Bay and James Bay coasts, largely reflecting the particular exposure and slope of the coast, and the fetch and severity of storm events. [...] The major ecological processes influencing the landscape of the Lowland are directly related to the rapid uplift and flattening of the region and to the rapid accumulation of sat- urated and frozen plant materials across most of the area. [...] These result in a general palud- ification of the landscape, the development of permafrost systems, and a relatively rigid gradient of differently aged landscapes from the coasts toward the interior of the Lowland.
