Abstract
Whilst the primary goal of species reintroductions has been the establishment of wild populations, there is increasing recognition of their potential to aid the restoration of ecosystem function. The goal of reintroduction has generally been population growth and the creation of wild populations, with most studies focusing on the dynamics of reintroduced populations, the practical methods involved and the subsequent success or failure of reintroduction. However it could be argued that the goal of reintroductions should be ecosystem restoration as the return of species should enhance ecosystem integrity (Armstrong and Seddon 2008); though few studies have examined the effects of reintroductions on ecosystem function (however see Hägglund and Sjöberg, 1999, Wilmers et al., 2003, Johnson and Cushman, 2007).
The reintroduction of species will likely alter ecosystems not only through the consumption of resources but also through the modification of habitat. Such modification can affect both the flow and availability of resources for other organisms. Species that modify, maintain or create habitat have been termed ecosystem engineers (Jones et al., 1997). These species may have a large impact on restoration, as success often hinges on the ability to restore biotic and abiotic resource
