The conservation status of the Nubian Bustard Nubotis nuba: a review and prognosis
Summary Records of the Nubian Bustard Nubotis nuba range across the drier northern component of the Sahel zone in Africa from Mauritania through Mali, Niger, and Chad to Sudan. Reports of significant hunting pressure have caused it to be treated as IUCN “Near Threatened” for almost 40 years, but information relating to distribution and population trends remains scattered, anecdotal, and unevaluated. All accessible evidence bearing on its conservation is therefore assembled and reviewed here. The lack of records from Mauritania since 1984, Mali since 1974, and Sudan since 1988 suggests that populations there may now be very small and perhaps entirely extinguished. Records from Niger and Chad remain many, thanks largely to the assiduous reporting of observations on the West African Bird DataBase (WABDaB) by researchers involved in ungulate conservation. The national nature reserves of Aïr and Ténéré (RNNAT) and Termit and Tin-Toumma (RNNTT) in Niger and the Ouadi Rimé–Ouadi Achim Faunal Reserve (RFOROA) in Chad emerge as vital to the long-term survival of the Nubian Bustard, given the accumulating evidence in both countries of (1) widespread habitat degradation and conversion, as human populations and their livestock expand in numbers and range in the Sahel, and (2) intensifying persecution, as highly mobile and well-armed local poachers plus Gulf state hunters gain increasing vehicular access to the remotest regions, depleting all huntable wildlife (a Sahel-wide bird study, 2011–2019, encountered just 16 bustards of four species – none Nubian – in 487 observation days). Populations of Nubian Bustard must now be greatly fragmented and depleted, with many entirely lost, so targeted programmes to minimise disturbance, persecution, and damage to habitat in the three key reserves (including the exclusion of powerlines) are urgently needed. Ultimately however the survival of this and other endemic Sahelian species can only be secured via a huge programme of ecologically and economically sustainable management practices.
期刊介绍:
Bird Conservation International is a quarterly peer-reviewed journal that seeks to promote worldwide research and action for the conservation of birds and the habitats upon which they depend. The official journal of BirdLife International, it provides stimulating, international and up-to-date coverage of a broad range of conservation topics, using birds to illuminate wider issues of biodiversity, conservation and sustainable resource use. It publishes original papers and reviews, including targeted articles and recommendations by leading experts.
