Abstract
Pollen records from 31 sites in southeastern North America document temporal and spatial patterns of vegetation change from the Last Glacial Maximum (LGM) (~22ka) to the present day. After southward migration of biomes during the LGM, warmer conditions during the deglaciation resulted in latitudinal and altitudinal shifts in forests. After a relatively dry early Holocene, wetter conditions and altered seasonality during the late Holocene provided the structure for modern biomes. High-resolution studies of the last few thousand years provide a context to evaluate vegetation changes tied to anthropogenic alteration of land cover.
