Abstract Title: CHINESE TALLOW ECOLOGY AND MANAGEMENT: WHERE DO WE GO FROM HERE? Warren C. Conway, Arthur Temple College of Forestry and Agriculture, Stephen F. Austin State University, Nacogdoches, TX
Abstract Text: During the last 20-25 years, a tremendous volume of research has been performed examining invasion potential, rapid spread, ecological impact, wildlife response, basic ecophysiology, remote detection, and control and management of Chinese tallow (Triadica sebifera; formerly Sapium sebiferum) throughout the southeastern United States. In sum, a tremendous body of both basic and applied knowledge exists for this species, yet, it continues to expand its range, and basic management issues still exist. For example, we know that tallow exhibits the traits of many successful exotic invasive species, such as rapid growth and sexual maturation, tremendous seed production, generalized habitat requirements, and few pests or pathogens in its naturalized range. Moreover, once established, we know tallow has the potential to become self facilitating, through rapid nutrient cycling. We know how to control tallow through combinations of properly timed prescribed fire and herbicide treatments. We know that tallow has few native herbivores, and many bird species, particularly yellow-rumped warblers (Dendroica coronata), forage upon tallow seeds and are effective seed dispersal agents. However, tallow seed and seed bank ecology universally remains a primary knowledge gap, because few studies have directly addressed natural seed bank dynamics, seed viability or longevity under natural conditions, nor seed bank expression after disturbances. Some past work indicates that tallow becomes an important element in areas impacted by small scale disturbances. However, a major portion of its range exists along the northeast and southwest Texas and Louisiana coasts respectively, which has been recently impacted by two large hurricanes (i.e., disturbances), which has dramatically altered regional physical and ecological structure. The potential for exponential expansion of tallow throughout the region, in response to these disturbances, is high, and will be outlined from a research and management perspective.
