Estimating the potential for reinvasion by mammalian pests through pest-exclusion fencing

Abstract: Pest mammals are completely excluded from Maungatautari Ecological Island, New Zealand, by a 47-km Xcluder pest-proof fence; however, they are commonly sighted directly outside, along the fenceline. Permanent pest exclusion relies on maintaining fence integrity, and enhancing knowledge of pest activity and behaviour at fenced reserves. We describe summer and winter periods of activity and behaviour of mammalian pests directly adjacent to the pest-proof fence. We (1) tested for the effects of adjacent habitat t… Show more

“…In such 3D environments, ship rats can avoid or rapidly escape from Norway rats, permitting local sympatry wherever there is enough food both above and on the ground (Innes et al 2001). The hood of a pest-proof fence, 2 m above the ground and a good place for hunting nocturnal insects, was a veritable highway for ship rats (Connolly et al 2009), from which they were perfectly positioned for immediate access into the sanctuary through any breach in the fence caused by a falling tree. Contrary observations from the wild are consistent with our results in other ways.…”

“…Mammalian pests constantly test exclusion fences, pushing against them regularly, and are able to exploit a weakness within 24 h (Connolly et al . ). While this study detected feral animals outside of the reserve, there was no evidence of feral animals trying to breach the fence through the one‐way gates suggesting one‐way gates are unlikely to pose an incursion risk if they are maintained and checked regularly.…”

“…The intention of the Mainland Island projects is to apply some of the pest management practices to intensively manage selected areas, with a focus on entire ecosystem restoration (Saunders and Norton 2001;Parkes and Murphy 2003;Parkes et al 2006). Management of Mainland Islands requires continuous pest control, because there is no barrier preventing recolonization exclusion fences have been successfully installed to keep mammalian pests out of some selected areas of high ecologic value (Day and MacGibbon 2007;Connolly et al 2009). …”
