Name: Populus tremuloides - Ceanothus fendleri / Carex spp. Scrub Reference: NatureServe Biotics 2019 Description: This quaking aspen shrubland 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 2512 to 2684 m (8241-8806 feet) elevation in areas that have recently experienced high-intensity fires. It typically occurs on plateaus, on gentle slopes (1-8°), and on south- or southwest-facing aspects, but can also occur on steeper sideslopes (up to 30°) as well. Soils are predominantly silty loams or sandy loams. This association lacks tree cover, as all of the trees have died in recent high-severity burns. A layer of regenerating <i>Populus tremuloides</i> characterizes this association. <i>Ceanothus fendleri</i> is a dominant and consistent component of the dwarf-shrub stratum, and <i>Mahonia repens</i> also occurs frequently. Dryland sedges are extremely frequent in this vegetation type, including <i>Carex rossii</i> and <i>Carex siccata</i>. Dominant forb species include <i>Achillea millefolium, Lotus utahensis</i>, and the fire-adapted <i>Gayophytum diffusum</i>. Other fire-loving species, including <i>Erigeron divergens, Chenopodium</i> sp., <i>Conyza canadensis, Pseudostellaria jamesiana, Pseudognaphalium macounii</i>, and <i>Arenaria lanuginosa</i>, occur sporadically.  Accession Code: urn:lsid:vegbank.org:commConcept:34263-{34174E2D-6E28-43B0-9907-80119638AD8C} Plot-observations of this Community Concept: 0
