Abstract

The objectives of this exploratory pollen analysis of selected samples from a sediment core taken at Hargrove Lake, Davy Crockett National Forest, Houston County, Texas, are to ascertain the quality of pollen preservation in the lake bottom matrix and to evaluate the potential of the pollen spectra deposited in the lake for providing information about former environmental conditions on Davy Crockett National Forest. Hargrove Lake is a natural lake in the floodplain of the Neches River in Houston County, Texas (Figures 1 and 2). The Hargrove Lake site (41H0150) lies a short distance to the west (Jurney 2000). The lake is presently is surrounded by a 10m wide stand of buttonbush (Cephalanthus). These plants are three m tall and have two to ten em diameter trunks. A woodland dominated by water oaks (Quercus nigra) and sweetgum (Liquidambar styraciflua) lies beyond the button bush. These trees are 30 to 40 m tall, and the woodland canopy is 90 to 98 percent closed. The lake is normally about 50 m wide by 200 m long, giving it a normal surface area of approximately 2.5 hectares. The mean depth of the lake at high water is about 90 em. Bedrock marl underlies the area, and the lake retains water during even the most severe droughts. It should provide a continuous pollen deposition record.
