The '''Chihuahuan Desert''' ({{lang-es|Desierto de Chihuahua}}, {{lang|es|Desierto Chihuahuense}}) is a [[desert]]
==Geography==
[[File:Chihuahuan Desert from South Rim BIBE.jpg|left|thumbnail|The terrain mainly consists of [[Drainage basin|basin]]s broken by numerous small [[mountain range]]s.]]
There are several larger mountain ranges in the
There are few urban areas within the desert: the largest is [[Ciudad Juárez]] with almost two million inhabitants; [[Chihuahua, Chihuahua|Chihuahua]], [[Saltillo, Coahuila|Saltillo]], and [[Torreón, Coahuila|Torreón]]; and the US cities of [[El Paso, Texas|El Paso]] and [[Albuquerque, New Mexico|Albuquerque]].

Safford and Benson in Arizona are located in low elevations of the western edges of the Chihuahuan Desert, but in an [[ecotone]] with the [[Sonoran Desert]].
According to the [[World Wide Fund for Nature]] the Chihuahuan Desert may be the most biologically diverse desert in the world as measured by species richness or endemism. The region has been badly degraded, mainly due to grazing.<ref name="WWF">{{WWF ecoregion |id=na1303 |name=Chihuahuan desert|access-date=2010-10-22}}</ref> Many native grasses and other species have become dominated by woody native plants, including creosote bush and mesquite, due to [[overgrazing]] and other urbanization. The [[Mexican wolf]], once abundant, was nearly extinct and remains on the endangered species list.<ref>{{cite web|title=Lobos of the Southwest| url=https://mexicanwolves.org/|website=Mexican Wolves|access-date=20 December 2017}}</ref>
==Climate==
The desert is mainly a [[rain shadow]] desert because the two main mountain ranges

Line 74 ⟶ 80:
The creosote bush (''[[Larrea tridentata]]'') is the dominant plant species on gravelly and occasional sandy soils in valley areas within the Chihuahuan Desert. The other species found with creosote bush depend on factors including the soil type, elevation, and degree of slope. Viscid acacia (''[[Vachellia vernicosa]]''), and tarbush (''[[Flourensia cernua]]'') dominate northern portions, while broom dalea (''[[Psorothamnus scoparius]]'') occurs on sandy soils in western portions. ''[[Yucca]]'' and ''[[Opuntia]]'' species are abundant on slopes and uplands in most areas, while Arizona rainbow cactus (''[[Echinocereus polyacanthus]]'') and Mexican fire-barrel cactus (''[[Ferocactus pilosus]]'') inhabit portions near the US–Mexico border.
[[Herbaceous plant]]s, such as bush muhly (''[[Muhlenbergia porteri]]''), blue grama (''[[Bouteloua gracilis]]''), gypsum grama (''[[Bouteloua breviseta|B. breviseta]]''),
Desert or arid grasslands comprise 20% of this desert and are often mosaics of shrubs and grasses. They include purple three-awn (''[[Aristida purpurea]]''), black grama (''[[Bouteloua eriopoda]]''), and sideoats grama (''[[Bouteloua curtipendula]]''). Early Spanish explorers reported encountering grasses that were "belly high to a horse"; most likely these were big alkali sacaton (''[[Sporobolus wrightii]]'') and tobosa (''[[Pleuraphis
The United Nations Environment Programme reported in 2006 that nearly half of the bird, mammal, and butterfly species in the Chihuahuan Desert are expected to be replaced by other species by 2055 due to climate change.<ref>{{Cite book|url=https://
