Biological soil crusts are a critical component of many arid regions. Where vegetation is extremely limited, such as Arabian sabkha!. these soil crusts may play many important ecological roles. These roles include nitrogen and carbon inputs, maintaining plant-essential nutrients in a bio-available form, influencing local hydrology. afTecting establishment of vascular plants, and decreasing soil erosion from either wind or water. Surface disturbance can heavily impact biological soil crusts, and often leads to reduced nutrient input and increased soil erosion. Little work has been done on Arabian sabkhat. although they may be an essential part of these ecosystems.
