Name: Pinus ponderosa / Carex siccata Woodland
Reference: Western Ecology Working Group of...
Description: 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 <i>Pinus ponderosa</i> dominate the canopy and subcanopy. <i>Abies concolor</i> occurs sporadically. <i>Ceanothus fendleri</i> and <i>Mahonia repens</i> are occasionally present, but the shrub strata are notably sparse. <i>Carex siccata</i> 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 <i>Achillea millefolium, Lotus utahensis, Lupinus argenteus</i>, and <i>Geranium richardsonii</i>. <i>Pteridium aquilinum</i> occurs occasionally. <i>Populus tremuloides</i> seedlings are ubiquitous at low cover.
