The Joshua Tree is a critical tree species found in parts of the Great Basin, especially in areas transitioning to the Mojave Desert.

The Joshua Tree (Yucca brevifolia) is well-adapted to the arid environment of the Great Basin and adjacent desert regions. These iconic trees thrive in the dry climate, low rainfall, and high elevation typical of the area. They play an essential role in the ecosystem by providing shelter and food for various animals, including birds, mammals, and insects. While Joshua Trees are most commonly associated with the Mojave Desert, their presence in transitional areas of the Great Basin highlights their importance to the broader desert ecosystem.
