Name:
Northwestern Chaco Xeromorphic Scrub & Woodland Macrogroup
Reference:
NatureServe Biotics 2019
Description:
This macrogroup represents the xeromorphic forests or woodlands of the northwestern Chaco region in southeastern Bolivia, western Paraguay and northern Argentina. These are 5- to 7-m high, semi-closed forests or thorn scrubs, deciduous, with scattered emergents 15-20 m tall. They grow on sandy loam or clay loam soils, moderately well-drained of the paleo-alluvial plains of large rivers existing in the region. Characteristic species are <i>Aspidosperma quebracho-blanco, Ruprechtia triflora, Schinopsis quebracho-colorado (= Schinopsis lorentzii), Chorisia insignis, Capparis speciosa, Capparis retusa, Capparis salicifolia, Ziziphus mistol, Stetsonia coryne, Cereus validus, Quiabentia pflanzii, Celtis chichape, Celtis ehrenbergiana (= Celtis pallida), Ximenia argentinensis, Castela coccinea, Browningia caineana, Acacia praecox, Cleistocactus baumannii, Arrabidaea truncata, Maytenus spinosus, Bougainvillea</i> spp., <i>Bromelia</i> spp., <i>Dyckia ferox, Caesalpinia paraguariensis</i>, and <i>Harrisia pomanensis</i>. Other types included in this macrogroup are the woodlands distributed in the northwestern edge of the Chaco region, along the foothills of the Andes. Diagnostic species of this type are <i>Loxopterygium grisebachii, Astronium urundeuva, Calycophyllum multiflorum, Phyllostylon rhamnoides, Acacia etilis, Schaefferia argentinensis, Saccellium lanceolatum, Tabebuia impetiginosa</i>, and <i>Caesalpinia floribunda</i>. A final xeromorphic woodland type included is a community type that grows on sandy soils (dune fields) from eolian sand deposits and on the sandstone hills of the northwestern Chaco in Bolivia and Paraguay. <i>Schinopsis cornuta</i> is the diagnostic species of this type.
