Desert Scrub: General

The Desert Scrub is a very humid and dry place and is almost an exact resemblance to a desert. However a Desert Scrub is filled with an abundance of plants and animals that have adapted to and thrived off of the intense climate of a desert. The rainfall is less then 10 inches per year and most of the time have a higher evaporation amount than precipitation amount.

Vegetation

Animals

Animals in the Desert Scrub are generally small and colors are light to reflect sunlight and protect against the heat. Many animals are nocturnal as the temperatures decrease drastically in the night. It could be anywhere above 100 degrees during the day to as cold as 20-30 degrees during the night time. There are also physiological adaptations such as salt glands that keep the salt levels high without losing fluids and the lack of sweat glands to also protect from losing valuable fluids.
