Country Life: Possums, stoats and hedgehogs no match for Canterbury's 4x4 trappers

It takes a village to raise a dotterel - because they can't get by on their own nowadays.

"You can see how vulnerable they would be," trap layer Ken Body said, standing over the remnants of a banded dotterel nest.

It's not much to look at - a circular scattering of twigs on the Rakaia beach's stony shore, fenced in by pieces of driftwood placed by Body.

"If we put some logs around it like this, most campers know there's something there, and they won't drive a motorbike in that area."

Body, a retired plumber, has trapped pests around the South Rakaia Huts since 2021.

He began trapping to protect the area's shore-nesting birds, who have few defences against introduced hunters, like stoats and hedgehogs.

Since he started, more than 900 predators have been caught.

That's brought back the birdlife in big ways: spoonbills, wrybills, native skinks and falcons have all been sighted in the area since then.

"I think we've got about 35 different bird species altogether."

Body's fellow bach-holders have noticed the birdsong too.

"Bellbirds would pop in occasionally, to this area, but never stay," he said.

"Now we do have quite a few breeding pairs building up. Even the farmers next to the settlement are noticing bellbirds in their trees.

"It's really made a difference."

Further south on the coast, Sarah and Chris Rickard run a majority cropping farm on a beach near the Hakatere Huts.

They're trapping to protect one of the country's largest breeding populations of shags, which visit the Hakatere Ashburton river's end.

Their eldest, Ella, 19, was inspired by her dad's career with the Department of Conservation to set up traps on the farm.

"Chris has been back on the farm for 23 years," Sarah said, "and [we] had no idea until we started trapping, that we had little weasels on the farm."

Kate Rickard, 17, is hoping to cross the ditch and do conservation work in Australia.

"I've liked doing all the conservation work with Dad," she said, having joined him for some work relating to kiwi birds in the past.

"If Australia doesn't work out, I could do [some] kiwi trips in New Zealand, do some trapping even."

Fifteen-year-old Rachel said her dream job would be conservation work in Africa.

"It'd be really interesting, with all the amazing animals."

Sarah is excited to see what their children achieve in the world of conservation.

"Following their passions sounds like fun.

"If it's involved with nature, that's really, really neat. Because that's what Chris and I are passionate about; it's nice that our girls are too."

Follow the river inland, and you might bump into Alastair Stewart and Ray Cossar.

The 4x4 enthusiasts trap around the local 4x4 park, nestled in the side of the river.

For Stewart, it's a way to give back to the environment, and to clean up the often-muddied reputation which 4x4 drivers have online.

"Between September, and the end of February, we like to keep the four-wheel drives out while the black-billed gulls are nesting in the river."

He said the time and consistency required for trapping made it an "old man's game".

"Retirees do it because they're available during the week. A lot of younger people are working and have families, and they just can't cope."

Stewart will pass the baton to Cossar to lead the trapping operation when the time comes - but for now, he's still a keen trucker and trapper.
