Agave lechuguilla Torr.
tridentata,
Agave lechuguilla, and Opuntia leptocaulis; however, only Prosopis glandulosa showed significant differences in IVI between sites with and without livestock (Table 2).
Agave lechuguilla is an agave species found in deserts.
Agave lechuguilla is a very common and abundant agave, so its conservation is not a problematic issue.
The most common plant debris sheltering whipscorpions were fallen leaves or stems of lechuguilla (
Agave lechuguilla), sotol (Dasylirion leiophyllum), blind prickly pear (Opuntia rufida), and rat-tail cactus (Coryphantha pottsii).
At both sites active shrews were most frequently observed under decaying leaves of lechuguilla (
Agave lechuguilla) and Torry yucca (Yucca treculeana) which had fallen to the ground, as well as under mesquite (Prosopis juliflora) and creosote (Larrea divaricata) shrubs.
One of the agaves, lechuguilla (
Agave lechuguilla), is considered the primary diagnostic species of the Chihuahuan Desert.
Another striking vegetation change was the loss of the succulent
Agave lechuguilla, which was gone from all 10 transects in 2014, having declined in cover from 3.9% in 1981 to 1.1% in 1995 (Table 1).
