CEGL008579 Pinus palustris - Quercus marilandica West Gulf Woodland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Longleaf Pine - Blackjack Oak West Gulf Woodland
Colloquial Name: West Gulf Coastal Plain Clayey Longleaf Pine Forest
Hierarchy Level: Association
Type Concept: This upland Pinus palustris woodland of the West Gulf Coastal Plain occurs in limited areas primarily north of the main contiguous belt of pure Pinus palustris vegetation. Sites on which this type occurs are believed to have a clay lens in the soil. Most known examples occur in a matrix of loamy Pinus palustris uplands. These areas were likely not subject to the most frequent fires typically associated with Pinus palustris vegetation. Due to infrequency of natural fires and soil conditions, the overstory may support a natural mixture of Pinus palustris and Pinus echinata and to a lesser extent, Pinus taeda. The presence of Quercus marilandica is characteristic of this type. Typically absent are species of xeric and very dry environments of the region.

Physiognomy and Structure: No Data Available
Floristics: Any given stand may be locally variable in terms of component vegetation. For more information on species present in this type see plots ANNF A 6106, ANNF A1407 (Turner et al. unpubl. data).
Dynamics: The natural fire regime is lower than that of other Pinus palustris communities.
Environmental Description: In eastern Texas this type occurs primarily on the Manning, Yegua, and Cook Mountain geologic formations. Soils at plot locations (Turner et al. unpubl. data) had silt loam surfaces, pH of 4.8-5.4, and low to moderate levels of all nutrients examined. These areas occur north of the main belt of existing and historical longleaf pine vegetation in the region (Bridges and Orzell 1989a, Evans 1997) where original patch size was much smaller, likely contributing to reduced numbers of lightning fire ignitions and greater fire-return intervals.
Geographic Range: This type is known from Texas and likely occurs in western Louisiana.
