Name: Carex siccata - Carex rossii Grassland
Reference: NatureServe Biotics 2019
Description: This high-elevation sedge herbaceous 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 2467 to 2688 m (8094-8819 feet) elevation, predominantly on the high-level plateau, on south- and west-facing slopes. Slopes are quite gentle, averaging 7°. Soils are well-drained or rapidly-drained silt loams. There is evidence of fairly recent, high-severity fire in all observed stands. This is a somewhat variable association but is characterized by a lack of tree cover, a very sparse shrub layer, and the dominance of <i>Carex rossii</i> and <i>Carex siccata</i> in the understory. Short shrubs are very uncommon and sparse, with the occasional small patch of <i>Robinia neomexicana</i>. Dwarf-shrubs are also sparse; however, <i>Ceanothus fendleri</i> is quite frequent. <i>Carex rossii</i> dominates the understory. <i>Bromus tectorum</i> and <i>Elymus elymoides</i> are also common at very low cover. Disturbance-adapted <i>Erigeron divergens, Chenopodium</i> sp., <i>Gayophytum diffusum, Pseudognaphalium macounii</i>, and <i>Conyza canadensis</i> are common forbs.
