One pig. One night. Fifty-six frogs.

Have you heard the tale of the frog in the pig? Here’s how it goes. One afternoon in 2010, a hunter was out in Coromandel’s Wharekirauponga Valley when he and his dogs cornered a feral pig in the bottom of a small stream. When he gutted it, he saw the pig’s intestines twitching, and when he slit them open, a tiny frog jumped out. Based on the hunter’s description, it was likely a native species, either an Archey’s or Hochstetter’s frog. That frog had a lucky escape and became the Little Red Ridi...

Land of the bright white light

Two scientists mapping New Zealand’s light pollution have found our nights became a lot brighter over the past decade—and that most of our public lighting is now bright blue-white light-emitting diodes (LEDs) which negatively affect human and animal health.

Te Pūkenga Nelson Marlborough Institute of Technology ecologist Ellen Cieraad and wildlife biologist Bridgette Farnworth used satellite data to map New Zealand’s light pollution and found it grew by 37.4 per cent from 2012 to 2021. That’s fa...

She’d spent the past few days in a flurry of calls and texts, even asking a cousin to get their local policeman friend to knock on her parents’ door to check they...

The wall that Frank built

The wall went up in 1964. It didn’t go up very far, mind you—1.4 metres of it was under the ground, with only about 50 centimetres sticking out the top. But Frank Evison, the prominent geophysicist who commissioned it, was satisfied.

Evison died in 2005, but the wall is still there. Low and grey and patched with lichen, set in a grassy river flat in the Maruia valley on State Highway 7, it’s surrounded by beech forest and dotted around with dandelions in the warmer months. If you just happened...
