The Biome of a Temperate Desert
By Lizz S. and Sam S.
- Average Annual Temperature: 20-25 degrees Celsius
- The temperature range during the year reaches as high as 40 degrees Celsius and as low as -18 degrees Celsius at night
- Average Annual Precipitation- less than 25 cm per year
- The main form of precipitation is snow or fog
Graph of Precipitation and Average Temperature
Other Limiting Factors
- The soils are coarse and rocky
- Hard for plants to grow
- Lie between 20-30 degrees North and South of the Equator
- High pressure areas
- Lack of precipitation
Types of Plants
- Prickly Pear and Saguaro Cactus
- Reduction of leaves, often into spines for protection
- Development of the stem as a major photosynthetic structure
- Water storage in the stem
- Development of defense structures
- Coating the plant with a thick waxy cuticle
- A dense coating of hairs (trichomes)
- Extensive underground root systems

- Eyes protected from the sun
Degree of Biodiversity
- The degree of biodiversity is high
- Many different types of plants and animals that thrive there.
