Type Concept: This quaking aspen woodland association is currently described from Grand Canyon National Park in Arizona. More survey and classification work are needed to fully characterize this type. It occurs from 2608 to 2689 m (8556-8822 feet) elevation on the plateau and on adjacent upper sideslopes in fairly recently burned areas. Slopes are typically moderate (10°), aspects tend to be northwest-facing, and soils are silt loams or sandy loams. This vegetation type occurs in areas that have experienced mid- to high-severity fires several decades ago. Populus tremuloides ubiquitously dominates the canopy layer; however, individuals are commonly less than 5 m in height. Previously extant conifers have experienced close to 100% mortality in these stands, but in the case of several surviving individuals, the Populus tremuloides layer may appear as a subcanopy. Vigorous regeneration of Robinia neomexicana also characterizes this vegetation type. Robinia neomexicana can appear as either a tall shrub or short shrub, depending upon the duration since the last fire event. Sambucus nigra is another frequent short shrub. Mahonia repens commonly occurs, but other dwarf-shrubs are infrequent. Carex rossii and Carex siccata are common members of a graminoid component. Forb cover is typically fairly sparse; however, Chenopodium sp., Machaeranthera canescens, Solidago velutina, and Chamerion angustifolium are common. Tree seedlings are essentially absent, as the duration since fire events has allowed the Populus tremuloides to mature. This vegetation type generally occurs in a mosaic among other regenerating mixed-conifer types and occasionally among mature, intact mixed-conifer stands.
