Upland Hardwood Forests
General Dry-Xeric Hardwood Forests
Habitat Overview This habitat includes dry upland forests composed mainly of oaks and hickories but also including Alleghany Chinquapin, a tree species often found in the same habitats. Some shrubs and herbaceous species are also included, where they occur primarily in association with dry to xeric hardwood forests.

This habitat is fairly widespread, covering at least two of the state's physiographic provinces. In the Coastal Plain, it shares a stronghold in the Sandhills with the Xeric-Mesic, Sandy Oak Woodlands habitat. However, this group also occurs in the Piedmont and Mountains where it is associated with dry ridges and south-facing slopes.

In addition to the hardwood species, this habitat also supports a number of herbivores that are specialists on them. One species, Edwards Hairstreak, belongs to a multiple-symbiotic complex, associated with xeric oaks as its larval food plants but also with species of Formica ants, which tend the larvae in return for their production of honeydew and also do the same for nymphs of Membracid treehoppers, particularly Smilia camelus (Weber and Nielson, 1984).
