Chinese tallow (Triadica sebifera) is one of the most aggressive invasive species in the southern forestlands of United States. To explore the stem taper of tallow, outside-and-inside bark stem profile equations were fitted using Max and Burkhart (1976), Cao (2009) modified Max and Burkhart, andClark, Souter, and Schlaegel (1991) segmented polynomial models. Sample trees were collected from oak-gumcypress (Quercus/Liquidambar styraciflua/Taxodium distichum) and longleaf/slash pine (Pinus taeda/ Pinus echinata) forests in southern Mississippi using destructive sampling method. Results showed that: 1) Clark, Souter, and Schlaegel (1991) segmented polynomial model was the best fitted model for both DOB and DIB stem profile of tallow in these two forestlands; 2) the stem of tallow was generally sturdy in oak-gumcypress forest while it was slender in longleaf/slash pine forest; however, no significant difference was found. Those models provide a tool for managers to project future growth stocking of tallow accurately and make
