ex-situ
Away from origin
Ex-situ describes conservation or scientific work conducted away from a species' natural habitat.
The term contrasts with in-situ, which refers to preservation in the original location.
Zoos, seed banks, and botanical gardens are typical ex-situ conservation efforts: The endangered orchid is being propagated ex-situ until its habitat can be restored.
In broader scientific contexts, ex-situ may describe any study or process performed outside its natural or original setting.
