Exceptional Work for Exceptional Species! – Cincinnati Zoo & Botanical Garden


Freezing plants in liquid nitrogen is not the last step in the journey of saving a species from extinction. Cryopreserved plant material can be thawed, grown in vitro on media that promotes root growth, acclimatized in order to live outside of a test tube, and planted back into its native habitat. Our work allows us to store plants long term and produce plants for in situ conservation efforts. We were recently awarded a grant from the Association of Zoos and Aquariums & US Fish & Wildlife Service that will allow us to do a full experimental cycle of tissue culture, cryopreservation, recovery & acclimatization, and finally outplanting to the native habitat for D. pulchellus and D. rugelii. This project will exemplify the process of ex situ conservation and will be used as a guide for conserving other exceptional species!
