Native American agriculture techniques once dominated the continent, but after the arrival of Europeans, many of those traditions were nearly lost. USDA’s Natural Resources Conservation Service is working with tribal communities and ethnobotanists to restore some of these techniques and crops.

NRCS Earth Team volunteer Ken Lair is working with the Big Pine Paiute Tribe of the Owens Valley in California to test a cultivation technique to stimulate growth of the plant nahavita, or blue dicks.

Traditionally, when native people harvested geophytes through digging, they did more than just retrieve the largest bulbs, corms, tubers and rhizomes for eating—they also replanted the smaller ones so that they could grow into new plants. Lair is testing this cultivation technique by growing nahavita at the Big Pine Indian Reservation.
