Campbell Islands Teal Anas nesiotis was formally recognised by BirdLife International in 2000 and immediately listed as Critically Endangered under criterion D1, as it had a population of fewer than 50 mature individuals.
Since 1999, a breeding, translocation and reintroduction programme has been successful in increasing the total population (captive and wild) to over 200 individuals (Potter 2006) on Campbell Island and Codfish Island at least. Based on the results of the programme, it is thought that by the 2011 Red List update, the species’s wild population will have exceeded the threshold of 50 mature individuals for at least five years.
It is therefore proposed that the species be downlisted to Endangered under criterion D1, on the basis that the population still numbers fewer than 250 mature individuals. Comments on this proposal would be welcomed.
