Hierarchy Level: Association
Type Concept: This ponderosa pine / sedge woodland 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 2351 to 2695 m (7713-8842 feet) elevation on various landforms, but most commonly on gentle, east- or south-facing sideslopes that range from 1-18° and are usually fairly gentle. Soils are well-drained sandy loams or silty loams. Litter ubiquitously dominates the ground cover, but a small amount of downed wood does exist. This association occurs in areas with a low-intensity fire regime, and some stands have burned recently. Open stands of Pinus ponderosa dominate the canopy and subcanopy. Abies concolor occurs sporadically. Ceanothus fendleri and Mahonia repens are occasionally present, but the shrub strata are notably sparse. Carex siccata is the most dominant and abundant component of the understory. Forb composition is variable, and at least 70 different species can occur at low covers. Notable species include Achillea millefolium, Lotus utahensis, Lupinus argenteus, and Geranium richardsonii. Pteridium aquilinum occurs occasionally. Populus tremuloides seedlings are ubiquitous at low cover.
