We define an ecosanctuary in a New Zealand context as 'a project larger than 25 ha implementing multi-species, pest mammal control for ecosystem recovery objectives, and with substantial community involvement'. present attributes of 84 projects meeting this definition, including three lacustrine islands, 16 marine seven ring-fenced ecosanctuaries, peninsula-fenced ecosanctuaries 51 unfenced mainland ecosanctuaries. Ecosanctuaries have biological social some returned threatened, previously...
ABSTRACT Land application has become a widely applied method for treating wastewater. However, it is not always clear which soil–plant systems should be used, or why. The objectives of our study were to determine if four contrasting soils, from the pasture regularly cut and removed, varied in their ability assimilate nutrients secondary‐treated domestic effluent under high hydraulic loadings, comparison with unirrigated, fertilized pasture. Grassed intact soil cores (500 mm diameter by 700...
Abstract Invasions by alien pest species contribute heavily to global biodiversity decline, with invasive mammals having some of the greatest impacts on endemic biota. Pest management within ecological restorations is therefore critical for conserving threatened Coordinating restoration efforts at scale requires evidence relative efficacy different pest‐managed approaches (“regimes”) enhancing biodiversity. Our national meta‐analysis 447 responses across 16 quantifies significant benefits...
Mesopredator and competitor release can lead to population increases of invasive house mice (Mus musculus) after larger introduced mammals are controlled or eradicated.In New Zealand, mammal-resistant fences have enabled multi-species mammal eradications in order protect indigenous species.When the only remaining these biodiversity sanctuaries, they may reach a high density, with potential consequences for their prey.We studied mouse populations absence other 5 years at fenced forest sites...
Identification of breeding sites remains a critical step in species conservation, particularly procellariiform seabirds whose threat status is global concern. We designed and conducted an integrative radiotelemetry approach to uncover the grounds critically endangered New Zealand Storm Petrel Fregetta maoriana ( NZSP ), considered extinct before its rediscovery 2003. Solar‐powered automated radio receivers hand‐held telemetry were used detect presence birds on three island groups Hauraki...
Opportunities to monitor natural island ecosystem recovery following the eradication of introduced predators are rare, and provide a useful comparison for programmes aided by active habitat restoration species translocations. We present an assessment current avifauna on Burgess Island, Mokohinau Group, 2 decades after kiore (Pacific rat; Rattus exulans) removal. The 4 most abundant land bird we recorded red-crowned parakeet (Cyanorhamphus novaezelandiae), bellbird (Anthornis melanura), tui...
Abstract Predation of eggs and/or chicks is the main cause nesting failure in birds. Nest predation has been studied many habitats New Zealand, but few studies have conducted urban ecosystems. Twenty-one nests four bird species (blackbird [Turdus merula], song thrush philomelos], fantail [Rhipidura fuliginosa], and silvereye [Zosterops lateralis]) were monitored over one breeding season Hamilton using time-lapse recordings. Five events filmed (two by cats [Felis catus], three ship rats...
When the abundance of ship rats (Rattus rattus) is reduced, sympatric house mice (Mus musculus) are released from constraints food shortage, intimidation or predation. As a result, may become either more abundant active and detectable. To distinguish between these effects, we monitored at eight sites within Pureora Forest Park during periods rat removal non-removal, supplemented in mouse-specific feeders to half sites. We used live-trapping estimate mouse relative abundance, tracking tunnels...
We undertook stratified random sampling of vegetation, soil chemical fertility and subsurface temperature at 38 sites on 15 geothermal fields in the Taupō Volcanic Zone, central North Island, New Zealand, to develop a quantitative classification vegetation types identify main environmental drivers composition. implemented this with fuzzy framework noise clustering. Gradients composition were derived using Detrended Correspondence Analysis ordination related physical parameters correlation....
The advent of mammal-resistant fences has allowed multi-species eradications mammals from ecosanctuaries on the New Zealand mainland.However, maintaining eradication house mice (Mus musculus) proven difficult, and at some fenced reserves they are only exotic mammal present reach a high population density.Over 5 years we examined impacts alone biodiversity Sanctuary Mountain Maungatautari by comparing forest blocks with relatively low numbers mice.We managed two independently sites within...
We used measurements of brood patch and moult status to estimate the breeding phenology New Zealand Storm-Petrel, using birds caught at sea within Hauraki Gulf Marine Park near Auckland, Zealand. Birds October–January had completely downy patches, whereas February–April bare patches with an observed male bias in February sex-ratio, consistent a female pre-laying exodus typical petrels existence unknown colony region. No captured exhibited primary moult, which is known occur storm-petrels...
A barrier to successful ecological restoration of urban green spaces in many cities is invasive mammalian predators. We determined the fine- and landscape-scale habitat characteristics associated with presence five predators (black brown rats, European hedgehogs, house mice, brushtail possums) three New Zealand cities, spring autumn, space types: forest fragments, amenity parks, residential gardens. Season contributed variations detections for all taxa. Rodents were detected least gardens;...
Determining pest mammal impacts and abundance in forests requires an understanding of how target species use vegetation compared with the ground. We used a novel device combining footprint tracking bite detection to survey for mammals at four levels New Zealand that had house mice (Mus musculus) alone, all widespread mammals, including mice, ship rats (Rattus rattus) brushtail possums (Trichosurus vulpecula). When were detected 93%, 35%, 17% 0% devices on ground, shrubs, subcanopy canopy,...
We provide a first assessment of various on-land capture methods for procellarid seabird, the New Zealand Storm-Petrel Fregetta maoriana, which had been presumed extinct but breeding site has just discovered on Little Barrier Island. In vicinity an active site, playback only, also involving newly isolated call from in situ deployed sound-recording devices, could efficiently be employed capture, while light attraction combination with achieved comparable success further afield. consider that...
