Swamp Forests on High Terrace Deposits in the Bluegrass and Knobs Regions of Kentucky
The distribution of swamp forest sites as indicated by Quercus bicolor is mapped for the Bluegrass and Knobs regions of Kentucky. Most of these are on high level ter- races probably deposited by rivers ponded during glaciation. For some sites species lists are presented and a preliminary analysis reveals compositional variation related to soil moisture and perhaps pH. Records of Q. bicolor, Q. michauxii and Habenaria spp. from these previously little described forests extend their known ranges. The urgent need for conservation of these swamp forests is discussed.
