Abstract
BOERNER, R. E. J. AND Do-SOON CHO (Dept. Bot., Ohio State Univ., 1735 Neil Ave., Columbus, OH 43210). Structure and composition of Goll Woods, an old-growth forest remnant in northwestern Ohio. Bull. Torrey Bot. Club 114:173-179. 1987.-Species composition, sizefrequency distributions, and environment-vegetation relationships were studied in Goll Woods, the last known uncut remnant of the Black Swamp forest of northwestern Ohio. Relatively well-drained fossil beach ridges were dominated by sugar maple (Acer saccharum) and beech (Fagus grandifolia), with sycamore (Platanus occidentalis) and white oak (Quercus alba) also common; poorly drained flats were occupied by silver maple (A. saccharinum), American elm (Ulmus americana), bur oak (Q. macrocarpa), and ashes (Fraxinus spp.). Transitional sites had higher abundances of basswood (Tilia americana), ironwood (Carpinus caroliniana), red oak (Q. borealis), and red maple (A. rubrum). Regressions of axis scores from Detrended Correspondence Analysis indicated relationships among species composition and soil texture. Bur oak, white oak, sycamore, chinquapin oak (Q. muehlenbergii), and cottonwood (Populus deltoides) had emergent individuals over 1 m dbh but lacked stems 300 yr ago.
