Despite its harshness, life thrives in the Sonoran Desert. Cactus trees, paloverdes, desert tortoises, Gila monsters, and roadrunners are among the hundreds of plant and animal species that make their home there.
The Sonoran Desert lies in the arid region west of the Rocky Mountains. It covers about 120,000 square miles of land in southern California, Arizona, and Mexico. The Mojave, Yuma, Pima, Chemehuevi, and Papago Indian reservations are located there. Tucson and Phoenix are two of the desert’s largest cities. Much of the area’s rain doesn’t come until the middle of summer, when it falls in sudden downpours.
With its thick, straight trunk and sturdy, curved branches, the saguaro cactus is one of the most identifiable plants of the Sonoran Desert. This mammoth cactus can attain a height of 50 feet and weight of eight tons over its 200 years of slow growth. Many desert animals depend on the saguaro for nourishment and shelter, including wood rats, Gila woodpeckers, gilded flickers, elf owls, and sparrow hawks, among others.
The migration of people from overcrowded cities to the solitude of the desert has established Palm Springs, California; Scottsdale, Arizona; and other towns as popular resort areas and retirement communities.
U.S.P.S. Introduces Nature Of America Series
On April 6, 1999, the U.S.P.S. issued the first stamp sheet in its 12-year Nature of America series.
Before settling on Nature of America, the U.S.P.S. discussed issuing a set of four American desert stamps, based on the popularity of the 1981 Desert Plants stamps. Over time, the concept for the stamps evolved into a set of six stamp sheets depicting six ecosystems found in America.
U.S.P.S. art director Howard Paine suggested the stamps all use artwork by John D. Dawson, who’d previously worked on the 1988 American Cats, 1990 Idaho Statehood, and 1998 Flowering Trees stamps. They believed it was important for the same artist to create the artwork for all the stamp sheets, so they’d look like a set.
Some of the design inspiration for these stamps came from the 1997 World of Dinosaurs issue. The Dinosaurs sheet featured a panoramic view with perforations punched into the ungummed sheet. While they liked the idea of picturing a larger scene, the team didn’t want to use the punched perforations, because it would distract from the design. Instead they opted for the self-adhesive format with serpentine die cutting for each stamp. These stamps would be the first U.S. self-adhesive issues designed as one large scene.
The result is a stunning sheet with 10 stamps, each including one or more species found in that region. Outside of each stamp there are additional plants and animals, so the sheets actually picture 20 to 30 different species. Plus, the back of each sheet includes an outline of the artwork and identification for all the plants and animals. Click here to see the back of the Sonoran Desert sheet.
While the scene pictured on each sheet came from Dawson’s imagination, it was thoroughly researched. He used photos as references for each creature and worked closely with scientists to ensure he pictured all the species interacting in a realistic way on every sheet.
The first sheet in the Nature of America series was issued on April 6, 1999. Picturing the Sonoran Desert, its first day ceremony was held at the Arizona-Sonora Desert Museum in Tucson, Arizona. According to a U.S.P.S. representative at the ceremony, “these stamps will help promote a greater appreciation for the diversity and beauty of our desert lands, and serve as a nature lesson for the enjoyment of young and old alike.” Among the ceremony’s participants were some of the animals pictured on the new stamps.
The Sonoran Desert and the other five planned Nature of America sheets proved to be so popular, the series was extended to include six more ecosystems. One sheet was issued each year from 1999 until 2010.
