Negev building solar energy plants in the Negev. As director of Ben-Gurion National Solar Energy Center, he operates one of the largest solar dishes in the world. Technically, however, the Arava is a separate desert with its own unique climate and ecology. A 250 MW solar park in Ashalim, an area in the northern Negev, was in the planning stages for over five years, but it is not expected to produce power before 2013. In 2008 construction began on three solar power plants near the city; two thermal and one photovoltaic. The Rotem Industrial Complex outside of Dimona, Israel, has dozens
Mojave Desert needed for survival in the flora of the Sonoran Desert, which has an overlap in its major flora, such as the creosote bush ("Larrea tridentata"). The soil types in the Mojave and Sonoran deserts are mostly derived from volcano, specifically the areas in California. As the topography goes down, particle sizes decreases as you move down the gradient, where you can also find low alkalinity. These erosional gradient is a habitat for many plant communities. As you go up the gradient of the desert, you will find more pediment and alluvial fan soil. In this areas, the flora is mostly
