White Pockets

Most Recent White Pockets Phenocam ImageThe Grand Canyon Trust hosts four of the SEGA gardens, including White Pockets, on land within an area covered by the Kane and Two Mile Ranches. Pinyon is the dominant vegetation type for the Little Mountain garden, which lies within the Kaibab National Forest.

The Grand Canyon Trust is a conservation organization that purchased the ranches and their grazing leases with the goal of working with land management agencies to maintain and restore the ecological, cultural, and scenic values of the lands. The ranches include about 1,000 acres of deeded land and grazing rights to an additional 850,000 acres of public land administered by the Kaibab National Forest, Bureau of Land Management, and Arizona State Land Department. The Kane and Two Mile Ranch Research and Stewardship Partnership was created to facilitate research, cooperation, and volunteer engagement that contribute to the long-term sustainability of native plant and wildlife communities while addressing livestock management needs. The partnership includes the Grand Canyon Trust, Bureau of Land Management, U.S. Geological Survey, Kaibab National Forest, Arizona Game and Fish Department, Northern Arizona University, and the University of Arizona.
