Invasibility of major forest types by non-native Chinese tallow in East TexasThis article is part of a larger document. View the larger document here.
Non-native invasive Chinese tallow trees [Triadica sebifera (L.) Small,formerly Sapium sebiferum (L.) Roxb.] are rapidly spreading into natural ecosystems such as forests in the southeastern United States. Using the 2001-2010 USDA Forest Service’s Forest Inventory and Analysis (FIA) data and forest land cover data, we estimated the regional invasibility of major forest types (groups), loblolly/shortleaf pine forests and oak/gum/cypress forests, by using Geographic Information Systems (GIS) and geostatistical tools. We defined the regional invasibility of a forest ecosystem as its susceptibility to the colonization and establishment of Chinese tallow, measured by a function of tallow presence and cover percent. The invasibility of these two major forest types to tallow has been estimated and potential management applications discussed.
