Oak–heath forest

From HandWiki - Reading time: 2 min
An oak–heath forest is a plant community association and type of forest ecology. It is a deciduous forest type of well-drained, acidic soils, characterized by oaks (Quercus) and plants of the heath family (Ericaceae).[1] It is commonly found in the high elevations of the eastern United States. Such forest areas typically have a dense fibrous root layer at the surface of the soil, and in many areas predominate on south-facing or southwest-facing slopes.{{Citation needed|date=March 2011} rests once featured American chestnut (Castanea dentata) as an important canopy species before being decimated by blight. The chestnut populations still exist today as sprouts, though they rarely reach maturity.[2]
Oaks
Oaks (Quercus) characteristic of oak–heath associations include white oak (Quercus alba), black oak (Quercus velutina), scarlet oak (Quercus coccinea), chestnut oak (Quercus prinus), and red oak (Quercus rubra).[2][3]
Heaths
Heath plants common to this ecology include mountain-laurel (Kalmia latifolia), various blueberries (genus Vaccinium), huckleberries (genus Gaylussacia), sourwood or sorrel-tree (Oxydendrum arboreum), and azaleas and rhododendrons (genus Rhododendron). These are all usually shrubs, except for Oxydendrum, which is usually a small tree. There are also heaths that are sub-shrubs, usually trailing on the ground, including wintergreens (genus Chimaphila and Gaultheria) and trailing arbutus (Epigaea repens).[2][3]
