click to update datacart
Name: Alnus oblongifolia / Leersia oryzoides Flooded Forest Reference: NatureServe Biotics 2019 Description: This lower-montane riparian association is known from the Gila River watershed and probably elsewhere in southwestern New Mexico at elevations from 1680 to 1740 m (5520-5720 feet) elevation, but it likely ranges from 1500 to 2200 m. Stands are known to occur on sidebars of moderate-gradient streams where flooding frequently occurs. Soils are reported as unconsolidated riverwash and weakly developed sandy-skeletal Mollic Fluvaquents. A closed canopy of <i>Alnus oblongifolia</i> and a highly diverse but variable mix of forbs and graminoids characterize this community (53 species have been reported for the type). Shrubs are generally poorly represented, although <i>Amorpha fruticosa</i> can be common. <i>Leersia oryzoides</i>, a wetland indicator species, is abundant and dominates the grassy undergrowth. Twenty herbaceous wetland indicator species have been reported for the type; <i>Carex aquatilis, Equisetum arvense, Rudbeckia laciniata</i>, and <i>Mentha arvensis</i> are usually present and well-represented to abundant. The exotics <i>Agrostis stolonifera, Schedonorus pratensis</i>, and <i>Melilotus officinalis</i> can also be abundant.  Accession Code: urn:lsid:vegbank.org:commConcept:34597-{ADFA2AE3-D951-4A41-9792-FFD9B3DE1694} Plot-observations of this Community Concept: 0
