Name:
Monte Cool Semi-Desert Scrub & Grassland Macrogroup
Reference:
NatureServe Biotics 2019
Description:
This macrogroup represents the plant communities of both the upper and lower elevations of the Monte biogeographic region in central to northwestern Argentina growing with a Mediterranean to tropical xeric climate. The former occur on gravelly soils, above 2500 m altitude. These are open xeromorphic scrubs usually accompanied by columnar and other forms of cacti. Diagnostic species are <i>Plectrocarpa rougesii, Plectrocarpa tetracantha, Bulnesia schickendantzii, Bougainvillea spinosa, Gochnatia glutinosa, Proustia cuneifolia var. mendocina, Larrea tridentata (= Larrea divaricata), Larrea cuneifolia, Chuquiraga erinacea, Trichocereus pasacana, Trichocereus terscheckii, Trichocereus schikendantzii, Opuntia</i> spp., <i>Dyckia velazcana, Deuterocohnia schreiteri, Deuterocohnia longipetala, Abromeitiella abstrusa, Pellaea ternifolia, Notholaena squamosa, Notholaena buchtienii</i>, and <i>Cheilanthes pruinata</i>. The communities in lower elevations (from 600-1200 m) grow in xeric intermontane valleys, topographically intricate with clayish to sandy soils. These are short, semi-open scrubs dominated by <i>Larrea</i> spp. ("jarilla"); diagnostic species are <i>Larrea tridentata (= Larrea divaricata), Gochnatia glutinosa, Zuccagnia punctata, Chuquiraga erinacea, Cercidium praecox, Larrea cuneifolia, Bulnesia retama</i>, and <i>Geoffroea decorticans</i>.
