The distribution of corticolous lichens was studied along Big Seven Mile Creek, a tributary of the Ohio River using step-wise discriminant analysis. The populations appear to respond to complex interacting gradients of humidity, periodic inundation and the abrasive action of water transported debris. Hacroepiphytic coverage and species richness increased with height of the tree bole. Of all species observed, Arthonia caesia (Flot.)Korb and Physcia acinulata Mul. Arg. possessed the highest tolerance to periodic inundation. In addition, these species were found to have the highest resistance to scouring by water-borne debris. Candelaria concolor (Dicks.) B. Stein, Parmelia hypotropa Nyl. and Physcia …

Flora And Vegetation Of Five Natural Wetlands In The Kanawha And Ohio River Floodplains, Southwestern West Virginia, Bernadine Phillips Brumfield
Theses, Dissertations and Capstones
Flora and vegetation were studied in five natural wetlands along the Kanawha and Ohio Rivers, southwestern West Virginia. Vegetation was analysed using a stratified-random approach with nested quadrats along line transects. The abundance of dead trees suggests an overall increase in water level with time. One to three canopy species comprise 75 percent of the Basal Area at all five sites. Acer rubrum and Quercus palustris are the dominant species at the Winfield East, Winfield West and Pt. Pleasant sites. Salix nigra is the dominant species at McCausland Run site and Acer saccharinum is dominant at the Guyan Creek Oxbow …
