Secondary Succession


Succession is defined as a shift in the local composition of species in response to changes that occur over time. Secondary succession occurs in an area that once had stable life but has since been disturbed by some major force. Deserts lack rain fall, and when they receive rain it often causes flash flooding. In the Mojave National Preserve, the most likely cause of a disaster would be a drought or a flash flood. In either case, soil would already be present and a whole multitude of different grasses and wildflowers, including Big Galleta, Indian Rice Grass, Bush Muhly, Fluff Grass, Red Brome, Desert Needle, Blue Dicks, Owl’s Clover, Red Maids, Apricot Mallow, Fremont's Pin Cushion , would be able to inhabit the land in addition to the hardy Creosote. If Joshua Trees were effected, then they would slowly grow back as well when their seeds found a suitable spot in the ravanged environment. After the basic ground cover is established, then all animals would be able to move back into their previous environment. This process would also require much less time than primary succession because soil is already present in this scenario.
