Name: Alnus oblongifolia / Leersia oryzoides Forest
Reference: Western Ecology Working Group of...
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 Alnus oblongifolia 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 Amorpha fruticosa can be common. Leersia oryzoides, a wetland indicator species, is abundant and dominates the grassy undergrowth. Twenty herbaceous wetland indicator species have been reported for the type; Carex aquatilis, Equisetum arvense, Rudbeckia laciniata, and Mentha arvensis are usually present and well-represented to abundant. The exotic Agrostis stolonifera, Lolium pratense (= Festuca pratensis), and Melilotus officinalis can also be abundant.
