The Desert Legume Program (DELEP) is dedicated to the preservation of legume biodiversity from arid and semi-arid regions of the world.

NEWS: DELEP is now administered by Boyce Thompson Arboretum! For decades, the program was a partnership between UA and BTA. In summer 2024, the seedbank, the heart of the program, moved to BTA.
