  • Bringing ngutukākā back from the brink

    Bringing ngutukākā back from the brink
    Nov 20 2024
    Ngutukākā, or kākābeak, is a popular garden plant in Aotearoa. But in the wild, it is now rarer than kākāpō, with only about 100 individual plants surviving on steep, inaccessible cliffs. The East Coast is one of its remaining strongholds and the Tairāwhiti Ngutukākā Trust is on a mission to bring the taonga back. Veronika Meduna joins the inaugural Tairāwhiti Ngutukākā Festival to find out more about the community’s efforts to turn State Highway 35 into a Crimson Highway by rewilding this iconic native.

  • A tricky trap for redback spiders

    A tricky trap for redback spiders
    Nov 13 2024
    Invasive redback spiders are highly venomous, threatening both people and New Zealand’s native species. A team of scientists is developing a cunning tool to trap male redbacks, by concocting an irresistible spiderweb perfume. We visit 800 captive redback spiders in the lab, learn about their wild mating habits, and check out the “spider arena” where the redbacks’ signature scent is put to the test.

  • The fight for the forest and the fernbird

    The fight for the forest and the fernbird
    Oct 30 2024
    About two hours south of Dunedin, in the Catlins, the Tautuku and Fleming rivers flow into the sea at Tautuku beach. Covered in native bush from headwaters to the ocean, this special catchment is home to many native, and some threatened, plants and animals. But there’s an ongoing battle. Browsing animal such as deer and pigs are destroying the undergrowth, while feral cats and stoats are predating on critters such as the mātātā, the South Island fernbird. We meet some of the people fighting back.

  • Lead bullets - a health risk for humans and kea

    Lead bullets - a health risk for humans and kea
    Oct 23 2024
    Every year in New Zealand, recreational hunters shoot more than half a million wild game. Most are shot with lead-based ammunition. Now, researchers are investigating what happens to that lead, and how much of it is getting into the food chains of humans and the endangered kea. Alison Ballance speaks to scientists at Nelson-Marlborough Institute of Technology, and kea conservationists and predator control experts at the Department of Conservation to learn more.

  • Can birds adapt their nest building for a warming world?

    Can birds adapt their nest building for a warming world?
    Oct 16 2024
    To keep their eggs safe, some birds build simple cup-shaped nests. Others craft elaborate fully enclosed domes, with porches, fake entrances and ledges. But is this intricate construction of nests a set, encoded behaviour? Or can birds adapt in different conditions? Researchers are keen to learn about flexibility in nest design, to better understand how different species might be able to respond as the climate changes.

  • Why we are still monitoring the ozone hole

    Why we are still monitoring the ozone hole
    Oct 9 2024
    Almost 40 years on from the first reports of the Antarctic ozone hole, and 35 years since the Montreal Protocol to ban CFCs came into effect, what’s going on with the ozone hole? How does it form? How do we measure it? And having solved the CFC problem, why are we still monitoring ozone so closely? Claire Concannon heads to NIWA's Atmospheric Research Station in Lauder, Central Otago, to find out.

  • Looking after our four-legged friends

    Looking after our four-legged friends
    Oct 2 2024
    We love our four-legged friends. It’s estimated about a third of New Zealand households share their home with at least one dog, and two thirds of dog owners consider their furry friends to be family members. Some dogs work, others keep us company, make us laugh, get us walking twice a day, and shower us with unconditional affection….. But are we looking after all their needs? Claire Concannon speaks with a dog welfare expert about the science behind how we know our dogs love us, and what to do to make sure we are looking after them.
