Are weka ‘good predators’?

January 14, 2021 by Kate Guthrie

Are weka ‘good predators’?

River tested as reinvasion obstacle to possums

Reinvasion by predators, of previously cleared areas, is one of the many challenges of becoming predator free. We can’t fence huge tracts of wilderness – but we can potentially make use of natural barriers. Possums, for example, may be reluctant to cross rivers. Possums may be reluctant to cross … [Read more...] about River tested as reinvasion obstacle to possums
