Name:
Great Plains Comanchian Ruderal Grassland & Shrubland Group
Reference:
NatureServe Biotics 2019
Description:
This group is found from Oklahoma though central Texas to western and southern Texas, and eastern New Mexico, south into Mexico. It is dominated by non-native invasive or native adventive grasses, forbs, or shrubs that become abundant after significant disturbance, often associated with agricultural activities, or a disruption of natural disturbance regimes. Common disturbances which favor establishment of this group include long-term, heavy grazing, planting exotic species for livestock forage, plowing land and then abandoning it, and a disruption of the natural fire regime. Vegetation cover varies from low to very high. Abundant species vary greatly in this group, depending on the geographic location, seed sources, and nature of land use. This group includes pastures characterized by non-native invasive grasses such as <i>Bothriochloa ischaemum, Dichanthium annulatum, Dichanthium sericeum, Pennisetum ciliare</i>, and <i>Setaria</i> spp. It includes pastures and other disturbed areas dominated by native increasers such as <i>Bouteloua dactyloides</i>, and successional shrublands of old fields, pastures and other cleared areas that were previously forested and dominated by native species of <i>Crataegus, Rhus lanceolata</i>, or <i>Baccharis neglecta</i>. In some cases, areas dominated by these species were originally planted, but now the species have become completely naturalized, and may dominate large areas. This group also includes native upland shortgrass prairie areas dominated by invasive <i>Prosopis glandulosa</i>.
