The Joshua Tree

The Joshua Tree, the largest of the yuccas, grows only in the Mojave Desert. It is an important part of the Mojave Desert ecosystem, providing habitat for numerous birds, mammals, insects, and lizards.

Scientists believe that the Joshua Tree is a holdover from a different era, and so, is slowly disappearing from the face of the earth. Because they require a cold period to flower, Joshua Trees are vulnerable to climate change. Models indicate that Joshua Tree National Park and much of the southern half of it’s range will be too warm in the next 50 to 100 years to support the Joshua Tree.
