Name: Monte Scrub & Grassland Macrogroup Reference: NatureServe Biotics 2019 Description: This macrogroup represents the mosaic of <i>Larrea</i> scrub and open <i>Prosopis</i> or <i>Geoffroea</i> phreatophytic woodlands characteristic of the Monte phytogeographical region in Argentina. They are distributed west of the Pampas and south of the Chaco, occupying the sandy alluvial plains between the Desaguadero and Colorado rivers, other smaller endorheic basins, and the valley between the pre-Cordillera range and the Andes Cordillera proper. The climate is xeric and elevation varies from 800 to 2200 m. <i>Larrea</i>, the dominant genus of this type of scrub, includes several species distributed according to the type of soil and its humidity, texture and salt content. In the alluvial plains <i>Larrea tridentata (= Larrea divaricata)</i> and <i>Larrea cuneifolia</i> are accompanied by <i>Atamisquea emarginata (= Capparis atamisquea), Lycium chilense var. minutifolium, Ximenia americana</i>, and <i>Condalia microphylla</i>, with <i>Ephedra breana, Atriplex lampa, Aristida inversa, Fabiana peckii, Flaveria bidentis, Prosopanche americana, Bulnesia retama</i> in the lower stratum, and <i>Prosopis flexuosa, Prosopis caldenia, Prosopis chilensis</i>, and <i>Geoffroea decorticans</i> forming the upper stratum. In the intermontane valleys it occurs on the sideslopes and up to 2400 m altitude. The cover is low and <i>Larrea</i> species alternate with herbs such as <i>Hyalis argentea var. argentea, Scleropogon brevifolius, Stipa cacheutensis</i>, and with small groves of <i>Discaria chacaye</i> in the river margins of the valley bottom.  Accession Code: urn:lsid:vegbank.org:commConcept:40978-{39480297-393F-4672-A724-2C48505D7008} Plot-observations of this Community Concept: 0
