CEGL005943 Alnus oblongifolia - Salix gooddingii Flooded Forest
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Arizona Alder - Goodding''s Willow Flooded Forest
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This lower-montane riparian association is known from small mountain drainages in the Rio Grande basin of south-central New Mexico, but it likely extends westward into the upper reaches of the Gila River and Mimbres River watersheds and possibly into Arizona. Stands are known to occur on cobbly sidebars along lower-montane streams and overflow channels at elevations of around 1620 to 1650 m (5300-5400 feet), but they likely range to from 1500 to 2200 m. Flooding can be frequent to infrequent (two-year estimated recurrence interval), but the water table usually occurs within a meter of the surface. Although sites may be dry on the surface for several weeks, they usually retain some moisture at lower depths during at least part of the growing season (usually there is evidence in stands of water stains and flood debris, indicating frequent flooding, perhaps on a biannual basis). This community type has moderately closed canopies of Alnus oblongifolia at heights up to 18 m with a subcanopy of Salix gooddingii. Fraxinus velutina may be common as well, but other tree species are minor or accidental. The dense tree canopies tend to preclude significant undergrowth, although Poa fendleriana can be abundant. The shrub Baccharis salicifolia can be well-represented, and Amorpha fruticosa can also be common. The type can occur in an ecological complex with community types from the Platanus wrightii and Juglans major alliances.

Classification Comments: Brown et al. (1979) designated an Alnus oblongifolia Association in the Mixed Broadleaf Series that forms part of their Interior Southwestern Riparian Deciduous Forests and Woodlands Biome. Laurenzi et al. (1983) defined a diverse alder type for central Arizona, with Arizona sycamore, velvet ash, and Arizona walnut as important codominants. Szaro (1989) also defined a widely distributed and varied Alnus oblongifolia Community Type with box-elder and velvet ash as common canopy associates. The alliance is referred to by Dick-Peddie (1993) as the Alder Series with a mixture of shrub, grass, and forb species.

Geographic Range: This association is found along Animas Creek and probably elsewhere in the Black Range (Sierra County) and other mountains of southwestern New Mexico and may occur farther west into southern Arizona and possibly in northern Mexico.
