Letter to the Editor The common warthog and its parasites in the Free State Province (South Africa) cannot be used to test the ‘enemy release’ hypothesis for an introduced species: the value of reference point information for testing hypotheses of change iven the conservation concerns raised by hand, the common warthog is distributed farther Ginvasive species, testing hypotheses dealing north (D’Huart & Grubb 2001), and Boshoff & with invasion biology are crucial to understanding Kerley (2013) suggest that its range extended the mechanisms and drivers of invasiveness. throughout the Free State, and propose the Orange Central to this though is a clear zoogeographical River as a southern range limit for this species. The foundation regarding areas where a species is common warthog became extinct in the Free State indigenous, and upon which an experimental before 1900, with the last known record being in design can be based. Recently Matthee et al.
