strategies have been implemented in response to the resilience and vulnerability of a selected ecosystem? The Mojave Desert is a world famous desert that occupies a significant amount of California and smaller parts in surrounding states. Covering thousands of square kilometers‚ the ecosystems can range from 100 meters below sea level up to 2000 meters above sea level. The biophysical interactions within these ecosystems such as earth movements‚ soil formation‚ weather and climate lead to very diverse environments
