Aerial Shot of DREC
Originally named Meloland Field Station and later called the Imperial Valley Field Station, the Desert Research and Extension Center (DREC) was established in 1912 and has grown from 10 to 255 acres. The Center  was established through the cooperative efforts of the University of California, interested citizens, growers, and the Imperial County Board of Supervisors. The Center's primary research areas are desert agriculture, field crops, alfalfa breeding, vegetable crops, livestock environmental and feedlot management, irrigation and drainage management, and pest management.

Among the Center's major contributions to desert agriculture are the development of several crop varieties including Calmar, Imperial, and Calicel lettuce; Moapa, UC Cibola, CUF 101, and Sonora alfalfa; UC 157 asparagus; Imperial artichoke; and UC Signal barley. Many current irrigation practices, including sprinkler irrigation and the use of plastic tile for field drainage, resulted from research conducted at the Center. The Center has developed key requirements for the livestock feedlot industry, and, because of its winter climate, it is a major germplasm testing point for various agronomic and vegetable crops.

Crops of importance in the area and at the Center are alfalfa, wheat, barley, cotton, melons, broccoli, cauliflower, lettuce, onions, and sugarbeets. In an area where annual rainfall is less than three inches, research stresses the development of optimal irrigation-fertilization strategies that take advantage of desert conditions. The Imperial Valley has an important cattle-feeding industry, and researchers use DREC facilities to study beef and sheep feeding practices under low-desert valley conditions, where summertime temperatures can reach 120 degrees Fahrenheit.

The natural vegetation is a sparse growth of quailbrush, creosotebush, inkweed, burage, wingscale, desert buckwheat, and mesquite. The Imperial Valley receives approximately 2.9 million acre-feet of water annually from the Colorado River through the All-American Canal and a series of many laterals managed by the Imperial Irrigation District. Currently the quantity used is not restricted as long as it is not wasted as surface runoff.
