Watching this happening, Whanganui farmer and Eco School owner Nelson Lebo saw an opportunity. He and his wife, Dani, are opening the gate to their 5ha farm for an hour on Sunday, too.
Kaitiaki Farm is 4km from Whanganui, on the way to Fordell. Mr Lebo wants to show how, with help from the Horizons Regional Council, he's doing his bit for water quality in the Purua Stream, which runs through it.
The 2015 flood did major damage, Mr Lebo said. It caused slips and took out 30m of stream bank.
With help from Horizons he fenced the waterway in August 2016 and over 1700 native trees and plants have been planted beside it since then. He's had the help of three schools and students at his Eco School.
"It's been a massive effort, but now all the properties below us - all the way down to Riverview Four Square - can benefit from cleaner water and moderated flow levels," he said.
The open day will be for an hour on Sunday morning, on steep terrain. Visitors are to park on the side road near 223 No 2 Line and gather at the gate at 10.30 sharp.
