'Assisting' the migration of species. This has many names, 'assisted colonisation', 'assisted translocation', 'assisted migration' and 'assisted movement'. In effect, it is about helping endangered species to move to a new area with a good habitat for them to survive. 'Passive' assisted colonisation focusses on helping species move themselves, while the most 'active' form implies picking up individuals and transporting them to a new location. This is different from reintroductions that are already a normal part of conservation programs. Climate-driven translocations constitute moving plants or animals to an area where they have never lived historically, a new location that is now suitable for them due to climate change.
