High Andean Moist Puna Bunch Grassland Macrogroup
Reference:
NatureServe Biotics 2019
Description:
Plant communities of the central Andes in Peru and Bolivia, growing above 4000 m elevation on slopes with poor, eroded soils due to landslides or the effect of periodic freeze and thaw. In this conditions grows a semi-open vegetation dominated by woody and suffruticose, usually cushion-forming, camephytes. Diagnostic species are <i>Azorella</i> spp., <i>Werneria ciliolata, Werneria dactilophylla, Englerocharis peruviana, Anthochloa lepidula, Dielsiochloa floribunda, Valeriana nivalis, Nototriche violacea, Nototriche purpurascens, Nototriche vargasii, Nototriche</i> spp., <i>Stangea rhizantha, Pycnophyllum molle</i>, and <i>Aciachne</i> spp. Other communities are included which grow in milder conditions with better soils and moisture availability; these form extensive grasslands dominated by short bunchgrasses alternating with a diverse flora of forbs usually forming cushions, and rosulate camephytes, currently heavily influenced by grazing. Diagnostic species of this community are <i>Festuca dolichophylla, Festuca rigescens, Deyeuxia vicunarum, Deyeuxia minima, Deyeuxia</i> spp., <i>Azorella diapensioides, Azorella biloba, Azorella multifida, Luzula racemosa, Stipa hans-meyeri, Stipa brachyphylla, Baccharis alpina, Erigeron rosulatus, Poa gymnantha, Poa candamoana, Scirpus rigidus, Paranephelius ovatus</i>, and <i>Gomphrena meyeniana</i>.
