Name: Acer negundo - Alnus incana ssp. tenuifolia Forest
Reference: Western Ecology Working Group of...
Description: This association is found in the mountainous regions of northern New Mexico in the Rio Grande and Pecos watersheds. It occurs in lower montane regions at elevations documented at between 2070 and 2160 m (6800-7100 feet). Acer negundo typically form closed-canopied, well-shaded gallery forests on streambanks and narrow sidebars. Dense thickets of Alnus incana ssp. tenuifolia are characteristic of the undergrowth along with a wide variety of other shrubs (18 species). The herbaceous layer is also very diverse but variable, with over 70 grasses and forbs reported for the type. The community is at least partially flooded every other year or completely inundated, on average, every four years. Flood debris is often evident near the banks as driftlines or larger debris piles. Soils are moist Entisols (Typic Fluvaquents and Oxyaquic Udifluvents) that are shallow and have a sandy to loamy layer over a gravelly-cobbly layer. They have wetness (hydric) indicators within the upper 40 cm.
