Reintroduction

The project is a threatened species reintroduction project. We are aiming at eradicating feral animals, predators particularly — cats and foxes — from a large landscape. We will be working with local Indigenous communities to achieve that eradication. We will be then reintroducing a whole range of Australian endangered mammal species that have disappeared from this landscape completely.

Klopfer and Gamble (1966) gave 16 female goats (C. hircus) 5 min of contact with their young at parturition. Nine of the mothers had been temporarily rendered anosmic (could not smell) at parturition by spraying a 10% cocaine hydrogen chloride solution into their nostrils 20–90 min prior to parturition. […] Eight of the nine females who were anosmic at parturition but could smell at reintroduction accepted their own offspring, as well as alien young during reinstatement.
