英文摘要: Chinese tallow (Triadica sebifera (L.) Small) is an invasive tree species that competes with native species in bottomland hardwood forests in the western Gulf Coastal Plain of the southern United States. While much research has been done on Chinese tallow in coastal prairie ecosystems focusing on its establishment ecology, there is little known about its impacts on stand dynamics in forested ecosystems, where it is a growing problem. A paired-plot design was employed in 23 different stands along the Neches River, near Diboll, Texas, to compare sites with contrasting abundance in Chinese tallow. The objectives were to (1) determine the impacts of Chinese tallow on stand dynamics, (2) examine its impact on the light environment, and (3) determine if edaphic factors were correlated with stand structure on sites with varying stocking of Chinese tallow. Stand structural metrics were measured in 2012 and 2013, and the below-canopy light environment was estimated using hemispherical canopy analysis. Soil samples were collected for analysis in 2013. For all species, stand density was greater in plots with abundant Chinese tallow, while basal area, quadratic mean diameter, and relative density were lower (p<0.10). Chinese tallow presence was negatively correlated with overstory diversity, density of native species, oak density. We observed a greater maximum stand density index for bottomland hardwoods than has previously been reported (1200 trees ha-1 at 25cm QMD). Stand structure was most correlated to soil metal availability, yet relationships were weak (R2<0.30), potentially indicating minimal differences in edaphic conditions across our stands. Management to prevent Chinese tallow from replacing native species in bottomland hardwood forests includes proper density management of stands in areas where Chinese tallow is likely to grow and early detection of gap formation to allow treatment of establishing Chinese tallow before it outcompetes regenerating native species. © 2015 Elsevier B.V.
