Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Blackjack Oak / Farkleberry / Poverty Oatgrass Scrub Woodland
Colloquial Name: Blackjack Oak Xeric Scrub Woodland
Hierarchy Level: Association
Type Concept: This xeric blackjack oak type is found in the Interior Highlands region and western edge of the Interior Low Plateau of the United States. Stands occur on xeric bedrock outcrops on moderately steep to steep south- or southwest-facing slopes and ridgetops of hills and mountains. Soils are rapidly drained and very shallow (0-40 cm). Parent material may be igneous or sandstone. The bedrock is often exposed with fragments of rocks and boulders strewn over the surface. The canopy is stunted (3-8 m) and forms a scrub woodland dominated by Quercus marilandica. Some Quercus stellata is present. The shrub layer is typically sparse (<50% cover) and contains Vaccinium arboreum, or occasional Vaccinium pallidum. The herb layer is sparse (<50% cover). Typical species include Danthonia spicata, along with Allium canadense var. mobilense, Cunila origanoides, Dichanthelium acuminatum, Diodia teres. Mosses and lichens are often prevalent, including the mosses Polytrichum spp. and the lichens Cladonia subtenuis, Flavoparmelia baltimorensis, and Myelochroa obsessa.
Diagnostic Characteristics: No Data Available
Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: The concept of the type is mainly taken from the Missouri state classification''s Xeric Acid (Igneous, Sandstone) Forest (Nelson 1985). Chert substrates are unlikely to contain this type. This scrub woodland type may also be treated as a phase of either sandstone or igneous glades. Quercus stellata can be present. Compare with ~Quercus stellata - Quercus marilandica var. ashei Interior Highlands Scrub Woodland (CEGL003884)$$. Pure Quercus marilandica vegetation is uncommon in the Arkansas Ozarks (D. Zollner pers. comm. 2000).

Floristics: The canopy is stunted (3-8 m) and forms a scrub woodland dominated by Quercus marilandica. Some Quercus stellata is present. The shrub layer is typically sparse (<50% cover) and contains Vaccinium arboreum, or occasional Vaccinium pallidum. The herb layer is sparse (<50% cover). Typical species include Danthonia spicata, along with Allium canadense var. mobilense (= Allium mutabile), Cunila origanoides, Dichanthelium acuminatum, Diodia teres. Mosses and lichens are often prevalent, including the mosses Polytrichum spp. and the lichens Cladonia subtenuis (= Cladina subtenuis), Flavoparmelia baltimorensis (= Pseudoparmelia baltimorensis), and Myelochroa obsessa (= Parmelina obsessa) (Nelson 1985).
Dynamics: Drought stress may act to open up the canopy (Nelson 1985).
