GENUS CODE: QUERC GENUS SCIENTIFIC:Quercus GENUS AUTHORITY: L. GENUS COMMON: Oak GENUS SUMMARY: A genus of about 350-530 species, trees and shrubs, of temperate, subtropical, and rarely tropical regions of the Northern Hemisphere. Oaks are the predominant tree of our area, with a variety of species dominating much of the landscape in nearly every ecological situation. Only in a few specialized (and usually in some sense edaphically extreme) communities are oaks generally entirely absent: deepest Coastal Plain swamps, some Coastal Plain depression ponds, wettest pine savannas, pocosins, spruce-fir forests, highest elevation northern hardwood forests, and mountain bogs. GENUS IDENTIFICATION: Identification notes: Many oak species are well-adapted to ecological situations in which fires frequently burn the ground layer. Fire-maintained communities of the Piedmont and Mountains typically have oaks such as Q. stellata, Q. marilandica var. marilandica, Q. ilicifolia, and Q. prinoides. The two latter species are normally shrubby, and have become rarer because of fire suppression (they require fire to prevent larger trees from outcompeting them). In contrast, Q. stellata and Q. marilandica var. marilandica become larger and more frequent in fire-suppressed conditions.
