Abstract
In 1943 Potsger and Otto (13) published the first paper on the pollen analyses of New Jersey peat which involved a series of five bogs from northern and northwestern New Jersey. These bogs represented a rather large geographical area, but their message was unusually uniform. One might, therefore, be justified to assume that the study gave a rather trustworthy history of the vegetation of the glaciated part of the state. From a forest constituted almost entirely of Abies, Picea, and Pinus, succession carried dominance to a pronounced Pinus period. This genus contributed as much as 80% of the pollens at these particular foot-levels. In the upper third of the sediment an association of Tsuga dn Quercus depressed Pinus considerably; and in the topmost levels Castanea entered as last invader of the crown cover.
