Conservation challenges and benefits of multispecies reintroductions to a national park – a case study from New South Wales, Australia

Abstract

Species reintroductions into predator-controlled areas are an increasingly used conservation tool. Typically, ecological outcomes of such projects (e.g. recruitment, predation) are the focus but seldom necessary legislative, policy, social and institutional processes required for establishing large projects. This particularly applies to protected areas, managed by governments for conservation. Reintroductions are recommended for a third of threatened Australian vertebrates, with the New South Wales Government boldly embarking on a 2013 initiative to return locally extinct mammals to three protected areas. We detail the legislative, policy, social and institutional processes required for one of these sites, Wild Deserts, in Sturt National Park. Seven locally extinct species, including the greater bilby (Macrotis lagotis), western barred bandicoot (Perameles bougainville), golden bandicoot (Isoodon auratus), greater stick-nest rat (Leporillus conditor), crest-tailed mulgara (Dasycercus cristicauda), western quoll (Dasyurus geoffroii) and burrowing bettong (Bettongia lesueur) will be reintroduced into two exclosures. The scale of the project required identification of an appropriate location, satisfaction of statutory requirements for major infrastructure in a national park, assessments of potential ecological costs and benefits, engagement of the national park agency and other stakeholders (Traditional Owners, other government agencies, neighbours), and staff training to meet government agency requirements. We outline the resourcing, costs and benefits of such a project on government-managed land along with lessons learnt for similar large-scale restoration and reintroduction projects. Future projects would benefit from understanding legislative and policy frameworks and the need for transparency, while maximising efficiencies.
