Name: Agave lechuguilla - Euphorbia antisyphilitica - Opuntia engelmannii Chihuahuan Desert Succulent Scrub Group Reference: NatureServe Biotics 2019 Description: This rocky site Chihuahuan Desert scrub group is characterized by the relatively high cover and rich flora of succulents such as <i>Agave lechuguilla, Euphorbia antisyphilitica, Echinocereus</i> spp., <i>Escobaria</i> spp., <i>Fouquieria splendens, Ferocactus</i> spp., <i>Opuntia engelmannii, Cylindropuntia imbricata, Grusonia schottii, Cylindropuntia spinosior, Yucca torreyi</i>, and many others. Perennial grass cover is generally low. The abundance of succulents is diagnostic of this desert scrub group, but desert shrubs and subshrubs are usually present but not codominant, except for the near ubiquitous desert shrubs <i>Larrea tridentata</i> and <i>Parthenium incanum</i>. It is found in the Chihuahuan Desert on alluvial fans and fan piedmonts (bajadas), colluvial foothill slopes and ridges, and mesas. Sites are hot and dry, typically with southerly aspects. Gravel and rock are often abundant on the ground surface and the highest cover often occurs on limestones. Stands in rolling topography may form a mosaic with more mesic desert scrub or desert grassland groups. <i>Agave lechuguilla</i> is more abundant in stands in the southern part of the range. This group does not include desert grasslands or shrub-steppe with a significant cacti component, such as yucca or cholla grassland with a high grass cover.  Accession Code: urn:lsid:vegbank.org:commConcept:40049-{ADC2419F-9F0A-4023-BB7A-1A4D0F95A2B2} Plot-observations of this Community Concept: 0
