Marshall Forest is a virgin oak-hickory-pine forest in northwest Georgia that is an assemblage of chestnut oak, pine-oak, and mixed forest communities. A resurvey of permanent plots established 29 years ago within the mixed forest community of the forest indicates that basal area has increased by about 50 percent, at the same time mean stem density has decreased about 27 percent. Decreased species importance is noted for Pinus echinata, Liriodendron tulipifera, and Carya ovata. An increased importance is noted for Acer rubrum and Quercus prinus.
