Yucca brevifolia, commonly called the Joshua tree or tree yucca is a plant species native to southwestern North America in the states of California, Arizona, Utah, and Nevada, primarily in the Mojave desert area, thriving in the climate there. It is a valuable resource - native American tribes used its leaves for weaving sandals and baskets, while seeds and flower buds were nourishing meals.
- The tree is a common sight in the wasteland, with exactly 4,529 trees of all types present in the base game WastelandNV worldspace (TreeJoshANV,TreeJoshBNV,TreeJoshCNV,TreeJoshDNV,TreeJoshENV).

Raider: Jackal Gang
Raider: Scorpion Gang
Raider: Viper Gang
The Joshua Tree-speckled mountains provide a surprising amount of cover, especially the rock-strewn washes that run east-west just south of Nelson. This is the perfect location for packs of anarchic hunters, grifters, and psychotics to wait for an opportunity to steal, kidnap, or kill. These loosely-knit Raider gangs revel in chaos and anarchy. The Jackals are no more than a handful of scarred and tattooed reprobates, scraping out a living by praying on anything weaker than them. The (slightly) more more organized Viper Gang consists of a slightly more skilled collection of ne'er-do-wells, dug in close to major roads to rob and plunder travellers and Merchant Caravans. Further north, are two much more pitiful gangs, who have lost their brethren (both in violence, or by recruitment) to the Fiends; the stinking Greaser Gang who terrorize the North Vegas Sewers, and the Scorpion Gang, who fight intermittent skirmishes with Westside residents. All these Raiders have no driving purpose or goal, other than to live to see tomorrow and raise as much hell as possible today."
