sweetgum, green ash, water 6ak, willow oak Atlantic white cedar, and <br /> sycamore. The plantations were established either in the upper drawdown <br /> zone of the reservoirs (soils intermittently covered with 1-3 ft of <br /> water at normal pool level) or in surcharge zones (suils 1-15 ft above <br /> normal pool level that are flooded occasionally). Some plantations were <br /> established with nursery-grown seedlings, and tn other cases with <br /> transplanted seedlings. Five-year development of plantations of all <br /> eight species in the sureharga zone are discussed by cover and soil <br /> conditions, water-level conditions, and species. Average survival was <br /> 60% or better for all species except Atlantic white cedar. Height <br /> growth ranged rem 3.3 ft for water tupelo to 14.3 ft for sycamore in <br /> broom sedge cover areas; most species obtained their best height growth <br /> in sites with woody cover rather than broom sedge or hydrophytic weed <br /> <br /> 16. Stubbs, J. 1963b. Survival snd growth of sweetgum, Shumard oak, and <br /> spruce pine planted on a creek bottom site in the Carolina coastal <br /> plain. Journal of Forestry 61:386-388. <br /> <br /> Results are given of a study of sweetgttm, Shumard oak, and spruce pine <br /> planted in an area of cleared forest on a stream terrace (second bottom) <br /> near Charleston, SC Plots were planted in January 1955 with graded 170 <br /> seedlings raised from local seed A conventional 10-inch planting bar <br /> was used. Several planting spacings were evaluated; these were 4 by 4 <br /> 6 by 6, and 8 by 8 ft. After five growing seasons, any effects of <br /> spacing were not evident. Sweetgum had 91% survival and averaged 12.5 <br /> ft in height; corresponding values for Shumard oak were 72% and 5.2 <br /> and spruce pine 48% and 7.7 ft. Planted swaetgum exhibited vigorous <br /> growth and few individuals were overtopped by competing vegetation. <br /> Other desirable features of sweetgum that made this species particularly <br /> amenable to management include. (1) production of large quantities of <br /> easily collected seed most years; (2) good seed viability; (3) e~sily <br /> grown nursery stack; and (4) easy planting. The authors note that <br /> without cleaning and weeding, only the sweetgum plantings resulted in <br /> well-stocked, homogeneous stands. Patches of natural sweetgum, <br /> yellow-poplar, and oak of both seedling and sprout origin often outgrew <br /> the planted trees. <br /> <br />17 Toliver, J.R. 1986. Survival and growth of hardwoods planted on <br /> abandoned fields. Louisiana Agriculture 29(2):10-11. <br /> <br /> The article report~ on trials with six bottomland hardwood species that <br /> were planted on old soybean fields at Thistlethwaite Game Management <br /> Area in St. Landry Parish LA. Two soil types Baldwin and Dundee silty <br /> clay loams, were represented in the plantations. Both types are high in <br /> fertility, but the Baldwin soil type has a higher %lay content and lower <br /> permeability. Pecan, sweetgum, sycamore, and cherrybark oak seedlings <br /> were planted on soybean stubble after harvest in February. Green ash <br /> and bald cypress were planted on disked soybean fields that had lain <br /> fallow for 2 years. All seedings were 1-year-old bare-rooted stock that <br /> had tap rbots pruned to a length of 6-8 inches, and were hand-planted on <br /> a 10 by 10 ft spacing using a planting bar.
