Conservation action has prevented the global extinction of at least 28 bird and mammal species since 1993, a study led by Newcastle University and BirdLife International has shown.
Publishing their findings in the journal Conservation Letters, an international team of scientists have estimated the number of bird and mammal species that would have disappeared forever without the efforts of conservationists in recent decades.
The species include Puerto Rican Amazon Amazona vittata, Przewalski’s Horse Equus ferus, Alagoas Antwren Myrmotherula snowi, Iberian Lynx Lynx pardinus, and Black Stilt Himantopus novaezelandiae, among others. The researchers found that 21-32 bird and 7-16 mammal species extinctions have been prevented since 1993, with the ranges reflecting the uncertainty inherent in estimating what might have happened under hypothetical circumstances.
The study has highlighted the most frequent actions to prevent extinctions in these bird and mammal species. Twenty-one bird species benefited from invasive species control, 20 from conservation in zoos and collections, and 19 from site protection. Fourteen mammal species benefited from legislation, and nine from species re-introductions and conservation in zoos and collections.
The research team, involving experts from Sapienza University of Rome, Italy and the Zoological Society of London, among others, identified bird and mammal species that were listed as threatened on the International Union for the Conservation of Nature’s Red List.
