Rafting

As a generic term: the attempt to remove a threatened creature, community of creatures, or sometimes an entire ecosystem, from the location where it is threatened, with the intention of re-establishing the population under threat in some new, safe place where it can continue to thrive.

Probably the most famous of Earth-based rafting projects has been the Aphthonic intervention, in which a working group of the wizards of Atlantis attempted to save their most unusual species of flora and fauna from the destruction of their continent. (AWOM)
