Swooping down in a last-ditch effort to thwart extinction, conservationists have airlifted 50 mountain chicken frogs</a from the Caribbean island of Montserrat.
While conservation biologists prefer to help a species survive in its natural environment, extreme cases like that of the mountain chicken (Leptodactylus fallax) call for extreme rescue measures. Here we present eight more novel attempts at species saving.
Those eight species are: the California condor; the whooping crane; the kakapo; the black robin, from New Zealand, like the kakapo; the gaur, a bovine species; Przewalski’s horse; the Pyrenean ibex; the African wild dog.
