Pollen from Lake Annie, Highlands County, south-central Florida, can be divided into three zones.

Zone 2, dating from 13,010 to 4,715 B.P., has abundant pollen of Quercus</em> (oak) and Ambrosia</em> (ragweed), indicating an upland vegetation of oak scrub and prairie. From 4,715 B.P. to the present (zone 1), the modern flora and climate have prevailed.
