Name: Chilean Mediterranean & Desert Riparian & Flooded Forest Macrogroup Reference: NatureServe Biotics 2019 Description: The macrogroup includes riparian forests with a range of moisture availability in the central Chile region. These include well-developed, mid-stature dense forests on alluvial soils of the valley bottoms of large rivers which every year get temporarily inundated, with a floristic composition characterized by <i>Cryptocarya alba, Persea meyeniana, Drymis winteri, Luma chequen</i>, and <i>Myrceugenia exsucca</i>. Also included are open woodlands and shrublands restricted to a narrow strip along stream courses; the latter occur in drier climatic conditions and also under somewhat halophytic conditions in ravines across the central coastal plain. These are dominated by evergreen sclerophyllous trees or shrubs with a herbaceous stratum of ferns or halophilous grasses; diagnostic species for this type are <i>Salix humboldtiana, Psoralea glandulosa, Maytenus boaria, Tessaria absinthioides, Pleocarpus revolutus</i>, and <i>Distichlis</i> sp. Farther north, closer to the desert of northern Chile, the inland riparian communities grow under xeric conditions and high interannual variations in precipitation which generates salt deposits during the long dry periods. Species diagnostic of these communities are <i>Atriplex repanda, Prosopis chilensis, Prosopis flexuosa, Acacia caven</i>, and <i>Schinus polygamus</i>. Also in the transition from central Chile to the Atacama desert, another riparian type is included which occurs in the canyon bottoms of the Andean foothills. It is represented by a dense lauroid forest 10-12 m high, characterized by <i>Baccharis scandens, Cortaderia jubata, Equisetum giganteum, Escallonia angustifolia</i>, and <i>Myrica pavonis</i>.  Accession Code: urn:lsid:vegbank.org:commConcept:40914-{B4E7338E-B87C-4FAA-A7A6-57AA6D63BFBE} Plot-observations of this Community Concept: 0
