BRATrON, S. P. AND S. G. MiLER (Institute of Ecology, University of Georgia, Athens, GA 30602). Historic field systems and the structure of maritime oak forest, Cumberland Island National Seashore, GA. Bull. Torrey Bot. Club 121: 1-12. 1994.-Understory structure and composition for the maritime oak and oak-pine forests on Cumberland Island National Seashore varies from dense palmetto thickets to open understories with few shrubs. The purpose of this project was to investigate the possibility that understory composition was primarily an artifact of past agricultural activity, rather than a product of anthropogenic burning or of soil moisture gradients. Historic maps were utilized to select areas of forest that had: 1) no history as agricultural fields, 2) use as cotton fields during the plantation era of the late eighteenth and the first half of the nineteenth century, 3) use for grazing during the era of private estates from 1881 to 1916, and 4) combinations of 2 and 3. The canopy and understory of 27 sample fields or non-agricultural areas were sampled by at least four randomly selected 50 m line-intercept transects. Sites with no known history of agriculture had dense understories of saw palmetto, Serenoa repens, had relatively high dominance indices for red bay, Persea borbonia, had few vines and almost no grass and forb cover. Fields with a history of grazing during the late nineteenth century had very open understories with greater dominance of grasses and forbs and widely scattered rings of saw palmetto. Sparkleberry, Vaccinium arboreum, and pines, particularly loblolly, Pinus taeda, were also characteristic of these sites. Fields utilized for cultivation during the plantation era, but not shown as fields on the late nineteenth century map had intermediate densities of palmetto, including some sabal palm, Sabal palmetto, and high covers of grasses, forbs and vines. The non-agricultural sites had significantly greater depths of soil litter and duff, but there were no significant differences in litter or duff depth among the agricultural field types. The results imply that the open understories in the maritime oak forest have not historically been maintained by either anthropogenic or natural fire, but are artifacts of cultivation and human land management extending back to aboriginal settlement of the island.

Age structure and successional dynamics of a presettlement-origin chestnut oak forest in the Pennsylvania Piedmont. Bull. Torrey Bot. Club 121: 13-23. 1994.-This study investigated the community ecology of an old-growth Quercus prinus L. forest on a dry talus slope in southeastern Pennsylvania. Quercus prinus trees up to 367 years in age dominated the canopy layer. Acer rubrum L., Betula alleghaniensis Britton, Betula lenta L. and Nyssa sylvatica Marsh. occupied a small share of canopy space but dominated understory positions. Acer rubrum was the only canopy species present in significant numbers in the sapling layer. Presettlement forests of the region were dominated by Quercus velutina Lam., Quercus alba L., Castanea dentata (Marsh.) Borkh. and Carya spp. Following European settlement, frequent cutting and burning associated with the charcoal iron industry promoted oak coppice stands during the 19th century and prevented the development of a shade tolerant understory. Age determinations indicated that Q. prinus recruited continuously from 1625 until 1920. However, radial growth analysis indicated that peak recruitment of both the oak and mixed mesophytic tree species was associated with past disturbances. Cessation of frequent cutting, reduced occurrence of fire and the loss of C. dentata facilitated establishment of A. rubrum, B. lenta and B. alleghaniensis in the understory early this century. Results of this study indicate the potential for replacement of oak by more tolerant species on this and similar dry sites in the northern mid-Atlantic region which are traditionally considered to be physiographic or edaphic climaxes.

Torrey Bot. Club 121: 62-68. 1994.-We compared black oak (Quercus velutina Lam.) leaf and shoot parameters between current shoots from current buds and reserve shoots formed from reserve buds after winter clipping treatments. We compared small trees growing in the light of an open field to trees in the shade of a forest understory in order to test for the importance of current and stored resources in shoot development. The populations of reserve shoots formed after clipping were similar to normal current shoots. Compared to current shoots, reserve shoots had the same numbers of leaves with similar lengths. Leaf areas per shoot, leaf number per shoot, and leaf lengths were lower on reserve than current shoots in the shade, but higher in the light. Mean shoot and internode lengths were greater for reserve than for current shoots primarily because there were fewer reserve shoots less than 4 cm long, particularly in the light. Only a few reserve shoots were longer than the longest current shoots. Specific leaf area was the same on reserve and current shoots. Leaves on reserve shoots were less lobed then on current shoots. In general, shoot populations from the two different compartments of the bud bank were similar.
