Semiarid deserts are primarily found in Europe, Northern Asia, and the western states of the United States and are significantly less harsh as dry deserts. Semiarid deserts have two main seasons, summer and winter. The semiarid desert has an average temperature of 23° C during the summer, though it can reach 38° C during the day and 10° C at night. During the winter, temperatures can reach as low as -3° C. Average rainfall is very low, at 2-4 cm a year (The Desert Biome).
Although rainfall is minimal, dew accumulates on vegetation during the night, which can equal or even surpass the total annual rainfall. The terrain is comprised of relatively flat land surrounded by large rocky mountains. The soil found in semiarid deserts consists of loose innutritious rock underneath a layer of fine sand. This type of soil composition makes it hard for large vegetation to survive, leaving only small trees, shrubs, and durable cacti to grow. Animals use the shade from this vegetation as protection from the sun. Because of the limited vegetation and food sources, animal populations are dispersed. The animals that have managed to survive in this climate are small and include lizards, snakes, and insects (Major Types of Deserts on Earth). These organisms, including the newly discovered Bradyrhinus gironi, or the American Rhingon, have been able to survive in this environment because they have adapted to the harsh conditions.
