Name: Pinus palustris / Quercus marilandica / Schizachyrium tenerum - Muhlenbergia expansa - Bigelowia nuttallii - Packera obovata Woodland
Reference: Southeastern Ecology Working Gro...
Description: This sparse woodland is dominated by a scattered, somewhat stunted <i>Pinus palustris</i> canopy; <i>Quercus marilandica</i> forms a patchy stunted subcanopy. <i>Pinus taeda</i> may be abundant in fire-suppressed examples. <i>Schizachyrium tenerum</i> and <i>Schizachyrium scoparium</i> are dominants in the usually dense herbaceous layer. Herbs typical of both upland <i>Pinus palustris</i> woodlands and wetter <i>Pinus palustris</i> flatwoods occur, along with more calciphilic species (e.g., <i>Neptunia lutea, Delphinium carolinianum, Silphium laciniatum, Packera obovata (= Senecio obovatus)</i>). This community contains a highly unusual combination of species, primarily due to the close interdigitation of distinct soil and hydrologic conditions, that in turn reflect the mixed geological character of the environment. This woodland is known from the Dough Hills Member of the Fleming Formation, and is thought to occur primarily on Anacoco and Kisatchie-Anacoco soils which are inclusions in areas mapped as Vaiden-Watsonia. The Kisatchie and Anacoco soils are very strongly acidic silt loams over clay; Anacoco soils are underlain by siltstone. This community ranges from dry with a patchy herbaceous layer and foliose lichens, to more commonly mesic or wet-mesic with <i>Muhlenbergia expansa</i> and <i>Rhynchospora</i> spp. as codominants. The historical fire frequency is estimated to be 3-4 years and, along with edaphic conditions including rock layers near but not at the soil surface, fire is believed to play a role in maintaining the open physiognomy.
