Desert trees are specially adapted plants that thrive in arid environments with limited water. They often have deep root systems to access underground moisture and thick bark to reduce water loss. Common examples include the Joshua tree and the mesquite tree, which can survive extreme temperatures and drought conditions. These trees play a crucial role in their ecosystems by providing shade, shelter, and food for various wildlife. Their unique adaptations, such as small leaves or spines, help minimize water evaporation. Desert trees also contribute to soil stability and prevent erosion, making them vital for maintaining the health of desert landscapes.
