CEGL004060 Quercus montana - Pinus palustris Forest

Type Concept Sentence: No Data Available


Common (Translated Scientific) Name: Chestnut Oak - Longleaf Pine Forest

Colloquial Name: Southern Ridge & Valley Chestnut Oak - Longleaf Pine Forest

Hierarchy Level:  Association

Type Concept: This is an open-canopy forest found near the southern terminus of the Ridge and Valley in Alabama. Stands are dominated by Quercus montana with a significant component of Pinus palustris present. Stands are found on north- and northwest-facing slopes adjacent to dry or xeric ridgetops dominated by more pure stands of longleaf pine. This appears to be a naturally occurring mixed composition forest found in somewhat fire-sheltered areas.

Floristics: The canopy of this forest is dominated by Quercus montana (= Quercus prinus) but contains a significant amount of Pinus palustris. Other trees may be encountered, such as Carya pallida, Quercus velutina, Quercus rubra, Acer rubrum, Carya glabra, Nyssa sylvatica, Oxydendrum arboreum, and Carya ovata. The shrub layer may include Vaccinium pallidum, Vaccinium elliottii, Vaccinium arboreum, Ilex ambigua, Diospyros virginiana, Sassafras albidum, and other species. The herbaceous layer tends to be sparse. Species observed in stands of this type include Hexastylis arifolia, Piptochaetium avenaceum, Dichanthelium commutatum, Dichanthelium boscii, Chasmanthium sessiliflorum, Smilax hugeri, Polystichum acrostichoides, Euphorbia corollata, Euphorbia pubentissima, and other species (NatureServe Ecology unpubl. data).

Dynamics:  Although the specific role of fire in maintaining the structure and composition of this community is unknown, the presence of longleaf pine in these stands suggests that relatively frequent fires were historically important in this community. However, these stands tend to occur on steep slopes below fairly narrow ridgetops where the likelihood of natural lightning ignition is low and the spread of fires from adjacent uplands would be infrequent. These factors suggest a lower fire frequency than that associated with longleaf pine-dominated vegetation.

Environmental Description:  Stands have been documented on north- and northwest-facing, generally steep slopes in the southern portions of the Ridge and Valley (NatureServe Ecology unpubl. data). Although these stands occur in the Ridge and Valley ecoregion, they are found on unconsolidated coastal plain geology within the natural range of Pinus palustris.

Geographic Range: This vegetation type is presumably restricted to the Southern Ridge and Valley of Alabama.
