HABITAT TYPES AND PLANT COMMUNITIES : 
Eastern poison-oak is seldom abundant [8].  It occurs in open woodlands
of various mixtures:  longleaf pine (Pinus palustris)-scrub oak (Quercus
spp.), pine (Pinus spp.)-hardwood, and second-growth hardwood [9].  It
is found most often in scrub oak and pine woodland savannas with an
understory of ericaceous shrubs and bunchgrasses including threeawn
(Aristida spp.), needlegrass (Stipa spp.), and bluestem (Andropogon
spp.) [8].  Eastern poison-oak occurs under loblolly pine (P. taeda)
plantations in Louisiana [2].  It is listed as an associated species in
a big bluestem (Andropogon gerardii)-kochia (Kochia scoparia)-common
sunflower (Helianthus annuus) community that occurs in Kansas.  Other
associates in that community include western ragweed (Ambrosia
psilostachya), switchgrass (Panicum virgatum), lambsquarters
(Chenopodium album), and sedge (Carex spp.)  [6].  In Alabama, eastern
poison-oak is reported from a community in the Bee Branch Gorge Research
Natural Area which represents the southernmost limit of eastern hemlock
(Tsuga canadensis).  Tree associates of eastern poison-oak in this
community include eastern hemlock and American beech (Fagus
grandifolia).  Understory associates include muscadine grape (Vitis
rotundifolia) and cane (Arundinaria gigantea) [22].

Eastern poison-oak is seldom associated with other members of its genus
because of differences in soil requirements [8].
