REINTRODUCTION OF EXTINCT SPECIES OF LARGE HERBIVORES TO GILÉ NATIONAL RESERVE, ZAMBÉZIA PROVINCE, MOZAMBIQUE February 2010 TITLE: REINTRODUCTION OF EXTINCT SPECIES OF LARGE HERBIVORES TO GILÉ NATIONAL RESERVE, ZAMBÉZIA PROVINCE, MOZAMBIQUE AUTHOR: IGF FOUNDATION PUBLICATION: February 2010, Musseia, Gilé National Reserve, Zambézia Province, Mozambique FUNDING: FFEM & IGF FOUNDATION NATURE OF THE STUDY: Appraisal survey COUNTRY CONCERNED: Mozambique KEY-WORDS: Reintroduction - Extinct species – Large herbivores – Capture – Translocation – Monitoring ABSTRACT: This study was carried out within the project for the co-management of the Gilé National Reserve, Mozambique under the auspices of the Ministry of Tourism of the Republic of Mozambique and the IGF Foundation. The study was funded by the FFEM, the IGF Foundation and private donors. The purpose of the study was to assess the feasibility of the reintroduction of extinct species of large herbivores to the Gilé National Reserve. The Gilé National Reserve is considered as a suitable recipient area for succeeding a reintroduction operation given the recent and steady improvement of its management standards. Four candidate species of large herbivores are selected for reintroduction, namely: - the Southern African buffalo (Syncerus caffer caffer); - the Livingstone’s eland (Taurotragus oryx livingstonii); - the Nyassaland wildebeest (Connochaetes taurinus johnstoni); - the Crawshay’s zebra (Equus quagga crawshayi). For a number of reasons, the ideal source area would be the Niassa National Reserve. Risks are evaluated and alleviation means identified. The implementation of the operation is phased: - pre-translocation phase: preparation of the recipient area and the operation; - translocation phase: capture, transport, holding and release; - post-translocation: monitoring. The whole operation complies with the IUCN guidelines for translocation living organisms.

O estudo foi financiado pelo FFEM, a Fundação IGF e doadores privados. O objectivo deste estudo era avaliar a viabilidade da reintrodução de espécies extintas de herbívoros de grande porte na Reserva Nacional do Gilé. A Reserva Nacional do Gilé é considerada como sendo um local de acolhimento conveniente para conseguir a operação de reintrodução dado o melhoramento recente e importante do seu maneio. Quatro espécies potenciais de herbívoros de grande porte são seleccionadas para a reintrodução, nomeadamente: - o Búfalo da África austral (Syncerus caffer caffer); - o Elande de Livingstone (Taurotragus oryx livingstonii); - o Boi-cavalo do Nyassaland (Connochaetes taurinus johnstoni); - o Zebra de Crawshay (Equus quagga crawshayi). Para múltiplas razões, a área fonte ideal seria a Reserva nacional do Niassa. Os riscos são avaliados e as suas medidas de mitigação são identificadas. A implementação da operação segue as fases seguintes: - fase de pre-translocação: preparação da área de acolhimento e da operação; - fase de translocação: captura, transporte, monitoria no boma e solta; - fase de post- translocação: monitoria. A totalidade da operação segue os guiões da UICN relativos à translocação de organismos vivos.
