Coasts can therefore provide migration corridors for salt-tolerant plants, and in some cases the drifting of buoyant seeds in ocean currents can provide a transport mechanism between coasts. This plant is also used for decoration in many American gardens. The soil in the semiarid deserts range from sandy and fine-textured, to loose rock fragments, gravel, or sand. deserts of North America. contrasts with the higher density of vegetation in wetter
