Recent Centuries of Vegetational Change in the Glaciated North-Eastern United States

Abstract

1 Pollen data from 55 sediment cores show complex patterns of change in the vegetation of the north-eastern United States in recent centuries caused both directly and indirectly by human impact, as well as by climate change. 2 In the few centuries before European colonization, the abundance of Picea increased and Tsuga canadensis and Fagus grandifolia decreased in the northern part of the region, possibly due to climate cooling. In the rest of the region the vegetation was fairly stable in the few centuries before European colonization. 3 After European colonization, the abundance of Betula increased throughout the region in response to forest disturbance, while Tsuga canadensis and F. grandifolia decreased, at least in part because of greatly increased fire frequency. The decrease in T. canadensis was also caused by cutting for the tanning industry. In addition to Betula, successional species included Castanea dentata in the south and Abies balsamea in the north. Both of these have been severely affected in the last century by disease or insect infestation, probably exacerbated by their increased population densities. 4 Sorting out the direct and indirect causes of fluctuations in these species provides valuable information for predicting the responses of vegetation to continuing human impact and possible future changes in climate.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
