Building Connections

The Yosemite Ancestral Stewards (YAS) Crew is a stepping stone aimed at bringing more Native youth from the park's Traditionally Associated Tribes into Yosemite. Although the program is open to anyone between 16 to 30, its primary goal is to give Native youth from the Traditionally Associated Tribes the opportunity to work within their own homelands.

Crewmembers work on projects throughout the park, from within Yosemite Valley up to Tenaya Lake. Those projects are just as diverse as their locations, including anything from trail maintenance to black oak stewardship to wetlands restoration to cultural building repair. Much of the work the YAS Crew takes on is of particular importance to the crewmembers as well, whether because it involves culturally significant species or locations or because the projects were proposed by their own Tribal Elders.

The program also fosters professional development. Members don’t just undergo the training they need to do their work safely, such as how to handle chainsaws or how to do wilderness first aid, but they also attend resume workshops and learn how to navigate federal job sites. By the end of the program, YAS crewmembers have the experience and knowledge needed to enter the federal workforce.

Through building connections within and outside of the crew to gaining the skills that will propel them through the workforce to stewarding their ancestral homelands, YAS crewmembers protect their legacies and work toward better futures for themselves and their Tribes.
