The Huntington, in San Marino, CA, obtained a grant from American Public Gardens Association to study Quercus ajoensis and Q. toumeyi in collaboration with the Arizona-Sonora Desert Museum (ASDM) in Tucson, AZ. The objectives were to scout localities where the two Quercus species had been observed in the past, confirm or deny presence of the species in several mountain ranges which have poorly documented or otherwise dubious records, collect acorns or material for micropropagation, and voucher the species at each location.
