Control possums, rodents and large introduced grazers and the forest understorey explodes with growth. It’s easy to think that this is what the original forests of Aotearoa must have looked like, before Man and other mammals arrived. But ancient Aotearoa had its own large herbivores – the various moa species, that grazed the forest understorey. … Continue reading Moa vs Deer – are they so different?
Bushy Park-Tarapuruhi Forest Sanctuary and Historic Homestead lies 25km north of Whanganui and has a long history of community-led conservation, going back to the early 1960s. “It’s had its ups and downs,” according to Mandy Brooke who has managed the Sanctuary since 2014, “but it’s an amazing example of long-term conservation. The forest is a … Continue reading Community-led conservation dates back to 1960s at Bushy Park-Tarapuruhi
Monitoring is an essential part of measuring the success of a predator control programme, but monitoring methods used in forests may not be directly applicable to wetlands. Tracking tunnels may not work, for example, where water levels fluctuate significantly. It was an issue that faced Department of Conservation researchers Craig Gillies and Matthew Brady at … Continue reading Monitoring methods trialled in Whangamarino wetland
Injured and sick wildlife have been pouring into Dunedin’s new wildlife hospital since it opened just over a year ago. Some are sick and starving, others have had a close encounter with a shark, while a significant number of native wildlife were wounded during a narrow escape from people’s pets. Each patient has a story … Continue reading Wildlife Hospital patients show scars of narrow escapes
Weka are omnivores with a curiosity for anything new, which makes them vulnerable to 1080 poison. They’re known to swallow the types of pellets used in 1080 operations and for that reason, learning more about the costs and benefits to weka has been a recent research priority. Department of Conservation scientists Joris Tinnemans et al, … Continue reading Weka and 1080 – costs and benefits assessed

Have you thought about how your project contributes to the wider New Zealand Biodiversity Strategy? In a recent report published in the New Zealand Journal of Ecology, … Continue reading Community groups under the microscope
Many of NZ’s introduced mammal predators – including house mice – are good at climbing trees. To understand the impact they have on tree-nesting birds and other tree-living wildlife, we need to learn more about how predators use vegetation compared with the ground. Mice aren’t commonly found in trees, for example, but that changes in … Continue reading Tree-climbing habits of predators studied
Sometimes ‘old’ just can’t be beat! That certainly seems to be the case for old forest remnants, at least as far as our indigenous insects are concerned, according to research recently published in the New Zealand Journal of Ecology. Urban gardens can be full of plant variety and buzzing with insects. But take a closer … Continue reading Old forest remnant shows its worth
The Ruakuri Scenic Reserve, which includes New Zealand’s internationally renowned Ruakuri Cave, is an epic example of cave and karst landscape and sanctuary to New Zealand’s endemic and vulnerable fauna and flora, including long-tailed bats and bush falcons.

Most wild birds and animals don’t survive long if they go blind. Not so, our kiwi. The discovery of otherwise healthy, but blind wild kiwi living successfully on the South Island’s West Coast has revealed just how little kiwi rely on their visual senses. For kiwi, it’s all about smell, hearing and vibration. Most birds … Continue reading Blindness no big deal for Okarito wild kiwi
The first time that 80 double-trap DOC 200s were set out at the Wharariki Onetahua Restoration site they caught 29 rats and 25 stoats! Some traps caught two predators! Catching 25 stoats off 80 traps is an awesome total – but think about what that says about the sheer army of predators that wildlife at … Continue reading Protection and accessibility are key goals for Wharariki Onetahua Restoration
Not only do kea nest on the ground, but it takes about 4 months from egg-laying until kea chicks fledge. Four months is a long time to be sitting on the ground facing off the local stoats. Kea eggs, chicks and even adult incubating females are very vulnerable to predation. Aerial application of 1080 can … Continue reading Kea and 1080 – nesting success demonstrated
Researchers from the University of Otago and Department of Conservation have been investigating how to improve the plight of our endangered black-fronted terns in research recently published in the New Zealand Journal of Ecology.

Innovative ideas, funding support and well thought out planning are all going to be crucial in the months and years ahead for the Eastern Bays Songbird Project. The backyard component of the trapping programme is … Continue reading Eastern Bays Songbird Project ambitious and innovative
Predator control for conservation purposes tends to focus on reserves, sanctuaries and remnants of native habitat rather than open pastures. When researchers publish articles on pastural predator control, they’re generally focused on possums and TB eradication. But landscape scale predator control on multi-tenure farmland is increasingly playing a part in Predator Free 2050 goals and … Continue reading Hawke’s Bay study shows predator control contributes to farmland biodiversity
It’s the new group on the block. Predator Free Dunedin launched just a few weeks ago in early October. But while the umbrella organisation is newly formed, it’s made up of 20 well-established Dunedin volunteer groups and larger organisations representing a wealth of Otago conservation experience. “Predator Free Dunedin includes big institutions like the University … Continue reading Otago groups join forces for Predator Free Dunedin
Suburban gardens, city parks, reserves and thoughtfully planted urban spaces can mean that our cities are surprisingly diverse in plants and habitats. But so far reintroductions of native species have been restricted to islands, fenced sanctuaries and remote habitats. If there’s a sanctuary close to your suburb, like Zealandia for example, you may reap the … Continue reading Urban reintroductions – going wild in city spaces
The research happened a decade ago now – this paper was published back in 2008 – but how many people have even heard of the large, carnivorous Mercury Island tusked weta (Motuweta isolata), let alone the extraordinary story of its step back from the cliff-face of extinction? Despite its large size (adult body length 46–73 … Continue reading How a tusked, carnivorous weta was saved

You don’t hear so much about weasels. Their New Zealand distribution is patchy and their bigger mustelid relatives tend to dominate the mammal predator stories. But when there was a mast year in 2014, weasels as well as stoats turned up in the beech forests of Nelson’s Maruia Valley to feast on the bonanza of … Continue reading Weasels studied during Maruia masting event
They’re some of the youngest members of Ahipara’s small seaside community, but the children of Ahipara Sandhoppers are doing everything they can to help their environment from picking up rubbish, to growing plants for butterflies, trapping predators and even deconstructing broken appliances for recycling. What’s more – these Kaitiaki Kids haven’t even started school yet! … Continue reading Ahipara youngsters lead the way
It’s not quite a sugar-coated pill, but the principle is similar – a nice flavoured coating that not only encourages rodents to take the bait, but also protects the toxic cereal bait within from deteriorating over time and going mouldy. Norway rats, in particular, have been found to avoid mouldy bait. Research recently published in … Continue reading Researchers study new ways to stop bait going mouldy
With Orokonui Sanctuary nearby and the virgin forest of the Mihiwaka Reserve bordering their sheep and beef farm, Port Chalmers farmers John and Shona Chapman along with their son Robert and his family, had some good reasons for trapping predators on their own land. “We started trapping on the farm about two years ago, mainly … Continue reading Port Chalmers farming family helps keep ‘Halo’ free of predators

Teacher, Ryan Kiely says he can see the sea out his classroom window. “I … Continue reading Mangonui kids are creative and committed to helping kiwi
D-Block bait and DITRAC All-Weather BLOX are two commonly used, long-life rodent baits with the same active ingredient, the anticoagulant Diphacinone. Rats and mice need to consume bait over several days to get a lethal dose, so it’s important to keep them coming back for more. Although the toxin is the same, the two bait … Continue reading Bait consumption study shows what appeals to rats
When the Waitaki hydro system was developed, 7,400 ha of open braided river habitat and 3,900 ha of swamplands were lost in order to ‘bring power to the people’. As well as increased electricity generation, we gained 22,250 ha of lakes and 290 ha of lake shoreline, but at a cost. It is the iconic … Continue reading ‘Rivers Rare’ tells success story of Waitaki braided river conservation

With a vision to re-establish the once-common buff weka, Motatapu Station near Wanaka is tackling habitat restoration and predator control on an impressively large scale. Just check out the numbers so far: What’s even more impressive, is that predator control on the ground is carried out by just three people – station supervisor Russell Hamilton, … Continue reading Vision for buff weka drives Motatapu Station restoration
Peanut butter has long been used as a bait for rat traps. Possums have a fondness for the scent of cinnamon. But are they the all-time favourite foods of rats and possums? Researchers at Victoria University of Wellington used chew cards to check out what really tickles the tastebuds of two of our more common … Continue reading Better baits and better trapping
On 1 August five new stamps will be issued by NZ Post celebrating the possibilities of a predator free future. For the design team at NZ Post, it’s quite a departure from the usual subject matter of stamp issues. “The majority of our stamp issues look at culture, history, heritage and people,” explains Simon Allison, Head … Continue reading New stamp issue looks to predator free future
With the benefit of hindsight, its easy to condemn those who released rabbits in New Zealand and even more so, those who then released ferrets and stoats to ‘remedy’ the earlier error. What were they thinking? Did they really have no other control options open to them? Were they completely unaware of what the consequences … Continue reading Ferrets and Rabbits – and what history can teach us
Taupo DeBretts Spa Resort has a whole bunch of eco-initiatives in place to encourage their holiday park guests to reuse, recycle and reduce their impact on the environment.

The first time that someone from Northland’s ‘Kiwi Coast’ project visited Greta and Craig Harman’s Charolais cattle farm to monitor for kiwi presence, they didn’t need to scramble through bush looking for kiwi sign or stay up late playing kiwi call recordings to confirm that kiwi were present. “There were fresh kiwi footprints in the clay … Continue reading Kiwi are longterm residents at the Harmans’ farm
We’ve a lot still to learn about our lizards. In some of the remoter parts of Aotearoa/New Zealand, new species of skinks and geckos are being discovered even today and the role of our reptiles in the wellbeing of the wider ecosystem has not been widely investigated. A recent article by Debra M. Wotton et … Continue reading Seed-spreading role of lizards investigated
Last term Lynmore School in Rotorua took delivery of 10 rescue hens. “It was pretty cool,” says teacher Andrew Doyle. “They’re ex-battery hens.

Passerines are songbirds which can perch. More than half of all bird species are passerines and many of those found in Aotearoa/New Zealand are unique. Some, such as the South Island saddleback, South Island robin and mohua also have a few other attributes in common: they’re rare, very vulnerable to stoats and are relatively poor … Continue reading Poor fliers reluctant to cross water
Andrew Roxburgh reckons the Newtown area of Wellington where he lives is becoming a more wild place – “and that’s pretty cool!” Andrew is a volunteer with Predator Free Mt Cook/Newtown/Berhampore and says that as birds are spreading out from Zealandia, people are becoming more aware of them. They’re noticing native birds more. “Kaka are … Continue reading Everyday life goes ‘wild’ in Newtown
Like many modern-day medicines, rodenticides are often derived from natural sources. Plants may evolve toxic chemicals to protect them from grazers for example, and sometimes all that distinguishes a beneficial drug from a toxic poison is the dosage. In a recent issue of the NZ Journal of Zoology, Charles Eason, ecologist with Lincoln University (Lincoln) … Continue reading Rat poisons and human medicines have natural links
Every year David Bielski, manager of Craigmore Station in South Canterbury, plans to spend $50,000 of the station’s budget on fencing, planting trees and labour to increase biodiversity on the property.

Cats and dogs are both predators of rats – but to what extent is the presence of cats and/or dogs a deterrent to rodents? How do you even measure how ‘nervous’ a rat feels? Scientists in far-off Swaziland used some interesting techniques to determine how uneasy rats felt in the presence of their natural predators. … Continue reading Investigating a rat’s ‘landscape of fear’
When Guy Bowden’s parents bought a coastal farm at Matapouri, Northland back in the mid 1960s they immediately fenced off some of the bush. That was before the days of the QE II National Trust and land covenants. Nowadays 94% of the 124 hectare family farm is in QE II covenant, made up of pohutukawa … Continue reading Tawapou Farm hosts kiwi and grey-faced petrels
Predator Free Great Barrier or Stewart Island? It’s already technically feasible. But is it socially feasible?When it comes to complete eradication of predators on inhabited islands there’s a lot more to consider than just the conservation benefits and technical aspects. People, their livestock, their pets and their lifestyle are all going to be impacted. In … Continue reading Eradication – what about the social impacts?
Not every species can be saved by moving it to a predator free island. It has helped the black robin – but it won’t help the black-fronted tern. Islands simply don’t have the habitat that the terns need to breed. Black-fronted terns have a small, declining population and are classified as globally endangered. Predation is … Continue reading No sanctuary option for terns
When Ōhiwa resident Andrew Glaser pitched the concept of a management group to coordinate protection efforts on and around the Ōhiwa Headland, the community immediately liked the idea. Andrew found out just how much they liked the idea not long afterwards, when he was walking his dog one evening. The conversation went something like this:(voice … Continue reading Small Ōhiwa community are big supporters of predator control
