A desert vegetation region typically has sparse plant life with scrub brush and cacti. These regions are characterized by low precipitation levels and high temperatures, which are ideal conditions for plants that have adapted to conserve water, such as cacti and other succulents.
The desert scrub climate is typically hot and arid, with low precipitation levels and high temperatures. It experiences extreme temperature fluctuations between day and night, and has low humidity levels. Vegetation in the desert scrub is adapted to these harsh conditions, with plants often having small leaves and thick waxy coatings to reduce water loss.
Rabbits and many other animals find shelter and food in desert scrub.
