Desert biomes , arid ecologic communities or bionetworks , cover one - fifth of the public ’s land mass and are extremely juiceless , with little rain . There arefour main typesof desert : hot and wry ; coastal ; semiarid ; and moth-eaten . Coastal deserts feature moderately cool winters followed by long , strong summers . The soil is sandy and ironic with a eminent salt content . The vegetation and fauna that exists in these area are not peculiarly diverse and are passing sturdy . Besides being drought tolerant , the plants also have peculiar shallow radical systems to catch any rainfall , and wide , blockheaded leaves for store wet .

Scrub

Much of a coastal desert landscape is dominate by bush , which are twiglike plants , sometimes bearing sticker . They have small leaves to prevent moisture loss and are shallow - root . Chaparraal is a coastal scrubbing and has the ability to live on just the wet in the aura from fog . Salt bush , euphorbia , senesio , chrysothamnus and artemesia are some of the other plants in a scrub wood . Rice grass and grim salvia also are found among scrub growth .

Cacti and succulents

We remember of deserts as being the home of cactus works , but actually the coastal desert has few . The sahuaro , a tall , columned cactus , is a classic feature of this country . It stores wet in its barrel- shaped body . A first cousin of the saguaro is the cardon , the largest cactus in the existence . Succulents like lithops are sprinkle here and there . broadly speaking low - growing with thick sarcoid leaves , succulent do take water and may be in phantasma or depressions that hoard wet from fog .

Trees

There are a few species of tree that survive the nutrient - pitiful sandlike soil of a coastal desert . The mesquite is a classic skeleton in the closet of a tree diagram that is used for it ’s wood . The ironwood tree diagram can get up to 30 feet in height or it can develop as a short , 2 - foot - gamey bush . Tall plants are rarefied in the coastal desert , which may average only 5 inches of rain per twelvemonth .

Creosote Bush

This George H.W. Bush is found ordinarily in coastal scrub regions and sends out a biting smell . They are boring growing and the seminal fluid are difficult to shoot . Consequently , it take a long time to regrow them once they are harvested , ordinarily for herbal remedies . Creosote can dwell up to 90 year and even a small President Bush can be 10 days old , due to the boring - growth pattern .
