Name: Abies concolor - Acer negundo / Alnus incana ssp. tenuifolia Riparian Forest
Reference: NatureServe Biotics 2019
Description: This white fir forest association is only known to occur at Bandelier National Monument in north-central New Mexico. The current description is based on data received from there and will be updated when additional inventory data are available. This association occurs on toeslopes and alluvial bottom terraces in riparian zones between 1800 and 2200 m (6000-7250 feet) in elevation. Slopes are gentle (4-12%) and aspects are variable. The vegetation within this riparian forest is characterized by a closed (60-90% cover), complex canopy composed of a mix of conifer and broadleaf deciduous trees. Typically, <i>Abies concolor</i> dominates with <i>Pseudotsuga menziesii</i> and <i>Pinus ponderosa</i> as codominant or subdominant associates. The broadleaf <i>Acer negundo</i> dominates the subcanopy along with <i>Alnus incana ssp. tenuifolia</i>. <i>Betula occidentalis, Quercus gambelii</i>, and <i>Prunus serotina</i> are occasional associates. Shrubs are poorly represented, while the herbaceous layer can be rich and abundant in cover and characterized by a mix of mesic forest and riparian species. Among graminoids, <i>Oryzopsis asperifolia</i> is the most frequent and well-represented. Forbs can be abundant and include facultative wetland species such as <i>Equisetum laevigatum</i> and <i>Hydrophyllum fendleri</i> along with mesic forest species such as <i>Thalictrum fendleri, Galium aparine, Viola canadensis</i>, and <i>Valeriana edulis</i>.
