How do you bring an endangered plant species back from the brink of extinction? The answer might be found in zoo animals.
That’s the inspiration for Chicago Botanic Garden scientist Jeremie Fant’s latest research. Fant, a molecular ecologist and plant genetics guru, is working with other botanic gardens around the world to develop conservation and reintroduction plans modeled after the ones used by zoos to protect endangered animal species.
“When we conserve plant species, it’s possible to preserve hundreds of individuals, and the genetic information they contain, by banking their seed or using cuttings to propagate them,” said Fant. “But when this is not possible, these plant collections are maintained by continually crossing with other plants to produce new seed. This is akin to animals in zoo collections. Zoos have used genetic information to develop ‘studbooks’ to decide what crosses are compatible so they maintain genetic diversity and prevent inbreeding.”
Fant’s work is based on zoological cases including black-footed ferrets in the 1980s. Zoologists created a breeding program that ultimately reintroduced the threatened species back into the wild. The zoologists used genetic information taken from the remaining black-footed ferrets, and bred a strong, biodiverse population that could keep the animals healthy and, more importantly, increase numbers, which is the aim of all good conservation programs.
Fant’s work centers on one plant in particular: the Brighamia insignis, or “Cabbage on a stick,” or as we’ve fondly named it, “Cabby.” This is Cabby’s story:
