The idea was popularized among modern conservationists independently by Peter Scott and Gerald Durrell in the 1950s and 1960s, founders of the Wildfowl and Wetlands Trust and Jersey Zoo, who demonstrated success with a wide variety of life forms in the 1970s ranging from birds (e.g. Pink Pigeon), mammals (e.g. Pygmy Hog), reptiles (e.g. Round Island Boa) and amphibians (e.g. Poison arrow frogs).
In 2009, a rescue plan involving the Durrell Wildlife Conservation Trust and the Wildfowl and Wetlands Trust removed a batch of ready-to-hatch eggs from a lake-side nest and incubated them in a lab that was set up in a tent by the side of the lake.
