    The challenges of making our capital city predator free

    Phase two of Predator Free Wellington’s groundbreaking project to rid our capital of rats is well underway. They’ve learned a lot from their work on the Miramar Peninsula, but with this new chapter comes new challenges – not just backyards, but a hospital, and even a zoo! Charlie Dreaver meets some of the team out fighting this battle on multiple interesting fronts.

    Building New Zealand's RNA capabilities

    Scientists had long been exploring RNA technology as a way to make vaccines before it had it’s breakout appearance during the Covid-19 pandemic. Since then, interest in the potential uses of RNA to make vaccines and disease treatments has bloomed. In late 2023 a government-funded platform began work to enhance New Zealand’s capacity to design and make RNA. Three years in, how is the platform going?

    Working towards a pest free Purerua-Mataroa peninsula

    One peninsula to the north of the Bay of Islands is home to an estimated three thousand Northland brown kiwi. The Pest Free Purerua-Mataroa project aims to reduce predators numbers on the peninsula and defend its narrow neck from re-invasion. Working across a patchwork of landuse and landowners, the team are using AI traps and technology to help catch the remaining pests. But one feral cat continues to elude them, and the ongoing threat to kiwi from pet dogs is proving tricky to solve. Sign up to the Our Changing World monthly newsletter for episode backstories, science analysis and more. Learn more: Northland kiwi are a genetically distinct subspecies of the North Island brown kiwi, whose numbers are doing pretty good in recent years, due in large part to Operation Nest Egg facilities like the National Kiwi Hatchery.Predator Free South Westland is also working across different land types and usages in their bid to remove pests from a huge area.Wellington is set to be New Zealand’s first predator-free city, with an ambitious target of ten years.RNZ’s Northland reporter Peter de Graaf has been following the situation of dog attacks on kiwi on the Purerua peninsula and kiwi deaths due to cars.Guests: Andy Mentor, Pest Free PureruaZane Wright, Pest Free PureruaMariao Hohaia, Ngāti Rēhia, Tapuaetahi IncorporationGrace Walsh, Onekura road trappersTiwai Rawiri, Ngāti Torehina, Pēwhairangi WhānuiGo to this episode on rnz.co.nz for more details

    Hydrogen detectives

    Could the answer to the current fuel crisis be right under our noses? On Our Changing World this week, Sharon Brettkelly talks to some of the scientists analysing ultramafic rocks in places like Lake Pupuke on Auckland’s North Shore and gases from various hotspots around the country, in the hopes that one day hydrogen could power local communities. Sign up to the Our Changing World monthly newsletter for episode backstories, science analysis and more. Learn more: New Zealand already has hydrogen trucks on our roads and active hydrogen refueling stations. However, some critics say battery technology is a better way to decarbonise. After delays from an international supplier, diesel trucks are being converted to hydrogen in New Zealand. Professor Allan Blackman looks at how the Hindenburg disaster has haunted the development of hydrogen technology and why that might be changing. And Jesse talks with Dr. Linda Wright from the New Zealand Hydrogen Council about if hydrogen could displace diesel.Guests: Kevin Faure, Senior minerals geologist and Team lead National Isotope Centre, Earth Sciences New ZealandPaul Viskovic, Geomodeller, Earth Sciences New ZealandThijs van Soest, Isotope Hydrogeologist, Earth Sciences New ZealandGo to this episode on rnz.co.nz for more details

    Looking to a wild future for kākāpō

    Today kākāpō breed on three remote islands, each bird wears a transmitter and they are carefully monitored and minded. But the ultimate goal of the kākāpō recovery programme is to restore the mauri of the kākāpō – to have them back in our forests as wild, nameless birds. What are the steps to get there, and how can science help keep kākāpō safe through this transition? Sign up to the Our Changing World monthly newsletter for episode backstories, science analysis and more. Learn more: Kākāpō need new habitat, could fenced ecosanctuaries be an option? That’s why kākāpō were released into Sanctuary Mountain Maungatautari in July 2023, to start a trial of how they would do in this new, mainland, North Island habitat. A year later, there had already been a lot of lessons learned.One of the possible future habitats mentioned by Deirdre Vercoe is South Westland, where a massive effort is underway to clear stoats, possums and rats from a huge area.For all the details about this record-breaking breeding season, listen to the Kākāpō Files podcast.Guests: Deirdre Vercoe, Kākāpō and Takahē recovery programme operations manager, Department of ConservationDr Andrew Digby, Kākāpō and Takahē recovery programme science and technical advisor, Department of ConservationGo to this episode on rnz.co.nz for more details
