Flowering of range ratany and creosote bush was considerably later than the other five shrub species (Table 3).
8% in creosote bush in the non-nest area (Table 5).
Rissing (1988) also observed the defoliation of creosote bush leaves by seed-harvester ants in southern Nevada.

The vegetation is dominated mainly by creosote bush scrub (Larrea tridentate) along with other plant species such as: anacahuite (Cordia boisieri), black brush (Acacia rigidula), ocotillo (Fouqueria splendens), coyotillo (Karwinskia humoldtiana), bear-rass (Yucca sp.
The same site of creosote bush scrub vegetation was sampled fortnightly.
In comparison, Blake (1984) reported 47 species of birds (four groups/seven subgroups) from a creosote bush community in a desert site of Nevada (Christmas Tree Pass region of the Newberry Mountains, Clark Co.
While the exact nature of the basis for this increased diversity of insectivorous foraging strategies remains unclear, it appears to be dependent upon variation in productivity of the desert ecosystem rather than upon the creosote bush.
Among the 40 different plants Eischen has tested, the most promising plants are creosote bush
and dried grapefruit leaves.
It also has tortoises, raptors, ghost towns, intaglios on the ground, and clone rings of creosote bush.
Four self-guided trails--from 500 yards to 1-3/4 miles--meander through the creosote bush habitat favored by the reptiles; it's now fenced and closed to vehicles and grazing.
The eastern half is dominated by creosote bush, spidery ocotillo, and cholla cactus.
