This unique desert is home to the most recognizable cactus
in the world, the majestic saguaro. Saguaro cacti provide their sweet fruits to
hungry desert animals. They also provide homes to a variety of birds, such as
the Harris’ hawk, Gila woodpecker and the tiny elf owl. Yet, the saguaro
requires other desert plants for its very survival. During the first few years
of a very long life, a young saguaro needs the shade and protection of a nurse
plant such as the palo verde tree. With an average life span of 150 years, a
mature saguaro may grow to a height of 50 feet and weigh over 10 tons.
