Subtropical climate of the Sonoran Desert

​Sonoran

The climate is hot in summer and cool in the winter, a warm- temperate climate

​Mojave

The Climate

Physical Characteritics

The terrain contains numerous mountain ranges, and the valleys are narrower than in the Lower Colorado River Valley subdivision. Trees are common on rocky slopes as well as drainage, and saguaros are found everywhere but on the valley floor. This community is also called the saguaro- palo verde forest.

​Sonoran

Mountain ranges, dry river beds, great mesas, towering sand dunes, striking cinders cones, domes and lava flows.

Mojave Region

The Mojave Desert occupies more than 25,000 square miles( 65,000 square km) and joins the Sonoran, Great Basin, and Chihuahuan deserts in the forming the North American Desert

​The Mojave Desert spans four states: California, Nevada, Utah and Arizona. In California, it takes up 20 million acres—about one-fifth of the state. The western deserts represent the largest intact ecosystem in the 48 contiguous states.

Sonoran Region

More specifically includes

Southern Arizona north to the Mogollon Rim

The southeastern corner of California ( roughly south of a line drawn from Needles to Palm Spring to San Diego)

The State of Sonora

The Baja California peninsula of Mexico

The Gulf of California and its islands

• The region interpreted by the Arizona-Sonora Desert Museum consists of the Sonoran Desert itself and included and adjacent habitats that influence its ecology and climate.

More specific locations of the Sonoran Region

Sonoran Movement

It has been postulated that over exploitation by Stone Age Native Americans may have led to the documented extinctions of Pleistocene megafauna in North America. Archeological remains indicate that later inhabitants, the Hohokam, impacted flora and fauna by selective hunting/ collecting practices and by dispersing species throughout the Sonoran Desert.

Mojave Movement

The Mojave shelters a huge range of plants and animals. Simultaneously, it's 20 million acres offer up a multitude of opportunities from recreation to ranching, from mining to military training for people. Miners, ranchers and farmers all depend on the desert for their livelihood. With every branch of the military maintaining an installation in the desert, the Mojave is a critical training location for the U.S Department of Defense

Multiple Choice

Which Native Americans may have led to the documented extinctions of Pleistocene megafauna in North America ?

• Indian

• Native

• Georgia

Multiple Choice

What are some of the opportunities done in the Mojave Desert ?

• Uber driver, restaurant workers

• ranching, military training

• Better living situations and school system

• Better high paying jobs and military training

​Sonoran H-E Interaction

As more and more people move to the desert to enjoy it's warm climate, the natural beauty that attracted them becomes paved over, torn up, and polluted. Important riparian areas are altered and destroyed, and water is scarcer than ever. As a result, species that have hardily to desert life for thousands of years are suddenly disappearing unable to adjust to human- caused stresses on their environment.

​Mojave H-E Interaction

Pollution from urban, agricultural and mining activities severely impacts the Mojave's delicate desert ecosystems and also puts human health at risk. Additionally, large numbers of people use the Mojave for recreation, causing further degradation.

​Sonoran Human Characteristics

Leonard Gaydos, Coordinator for the U.S. Geological Survey's (USGS) Recoverability and Vulnerability of Desert Ecosystems project, and colleagues are using satellte data to develop tools that will help Mojave Desert land managers decide what recreational activities to allow and where to allow them. Specifically, the research team is studying vulnerability of desert
