Today more than 45,000 acres of rolling grasslands and woodlands in southeastern Arizona are protected under the Las Cienegas National Conservation Area (NCA). The region’s oak-studded hills connect several "sky island" mountain ranges and lush riparian corridors. With its perennial flow, Cienega Creek forms the lifeblood of the NCA and supports a diverse plant and animal community. It is also rich in historic and cultural resources. The BLM has formed a partnership with the nonprofit Empire Ranch Foundation, which is dedicated to preserving the historic buildings and surrounding landscapes.
