Name: Southern Chaco Xeromorphic Scrub & Woodland Macrogroup Reference: NatureServe Biotics 2019 Description: The macrogroup includes open xeromorphic woodlands of the alluvial plains of the Argentinian Mesopotamia, an area wedged between the Uruguayan Pampas, and the Espinal and humid Chaco of Argentina. In this area two types of communities can be found. The first occurs on very flat, moderately drained and poor soils, and is dominated by <i>Acacia caven, Aspidosperma quebracho-blanco, Celtis tala</i>, and/or <i>Geoffroea decorticans</i>. The other type occurs on well-drained topographic uplands, and is dominated by <i>Prosopis affinis</i> or <i>Prosopis nigra</i>; a well-developed grassland occurs below the open tree layer. The macrogroup also includes the southern variant of the Chaco forests in central western Argentina. This forest is 5-10 m tall with scattered emergents, deciduous and with a semi-open canopy, growing on moderately drained soils. It shows an impoverished floristic composition, but at the same time it incorporates a few new elements from the adjacent Monte biogeographic region. Diagnostic species are <i>Aspidosperma quebracho-blanco, Prosopis flexuosa, Prosopis pugionata, Prosopis torquata, Cercidium australe, Larrea tridentata (= Larrea divaricata), Larrea cuneifolia, Mimozyganthus carinatus, Celtis ehrenbergiana (= Celtis pallida), Bulnesia foliosa, Bulnesia retama, Cassia aphylla, Condalia microphylla, Atamisquea emarginata (= Capparis atamisquea)</i>, and <i>Deinacanthion urbanianum</i>.  Accession Code: urn:lsid:vegbank.org:commConcept:41003-{4DB5819B-17BB-42B6-B028-BF5F2EFC32F3} Plot-observations of this Community Concept: 0
