Name:
Central Andean Xeromorphic Scrub & Woodland Macrogroup
Reference:
NatureServe Biotics 2019
Description:
This macrogroup represents the vegetation of the intermontane valleys of the eastern slopes of the Andes from central-northern Peru to Bolivia. In this case too, the strong climatic effect of the orographic rainshadow, creates xeric to semi-arid conditions. For communities distributed from 2100-3200 m elevation, diagnostic species are <i>Caesalpinia spinosa, Acacia macracantha, Kageneckia lanceolata, Tecoma sambucifolia, Tecoma arequipensis, Schinus molle, Schinus pearcei, Schinus dependens, Cantua pyrifolia, Mutisia acuminata, Colletia spinosissima, Carica quercifolia, Delostoma integrifolium, Zanthoxylum mantaro, Jacaranda mimosifolia (= Jacaranda acutifolia), Haplorhus peruviana, Apurimacia boliviana, Fourcraea andina, Cereus vargasianus, Chuquiraga ferox</i>, and <i>Puya</i> spp. The macrogroup also includes more dense woodlands in the lower portions of some of these valleys, between 900-2000 m elevation. Here they form a deciduous, semi-closed canopy 8-15 m tall, dominated by Anacardiaceae and Fabaceae species, accompanied by numerous shrubs and bushes, with many Cactaceae species. Lastly, the macrogroup includes scrub or very open sclerophyllous, evergreen woodlands of the Xerophytic Puna in southern Bolivia, northern Argentina and Chile, between 2000-3900 m elevation. The main tree component of these communities is <i>Polylepis tomentella ssp. tomentella</i>, accompanied by <i>Dasyphyllum hystrix, Berberis chrysacantha, Trichocereus tarijensis, Lophopappus cuneatus, Oreocereus celsianus</i>, and <i>Prosopis ferox</i>.
