Las Cienegas National Conservation Area

In a state where desert arroyos, washes and many streambeds remain bone-dry most of the time, the year-round flow of Cienega Creek makes it a highly valuable resource. A lush green ribbon of vegetation defines one of the most significant riparian zones in southern Arizona. Cienega Creek gets its name from the cienegas, or marshes, which occur along its length. This rare vegetation community has nearly disappeared in the Southwest.
