Agave delamateri?is known only from in and around archaeological sites in the Tonto Basin and Verde Valley in the Sonoran Desert in Arizona. ?It was cultivated during pre-Columbian times when various traits were selected for by the people managing the crop which lead to divergence from its closest wild ancestor (Parker et al. 2007). Referred to as a 'cultigen' this species is only from approximately 90 clones, does not reproduce sexually and has lower genetic diversity compared to other?Agaves. ?It is threatened by urban sprawl, creation of reservoirs, recreation activities and a fungus transported by the snout agave weevil.
