“The plants will help with erosion, increase biodiversity, and improve the water quality of the Motu catchment,” Ms Harley said.
“The students will be able to look after the area and there are plans for more plantings and predator trap monitoring,” she said.
Farmers in the area were keen to help improve the environment, Ms Harley said.
Mr Rau said they did this all voluntarily. “None of it on our farm is required by legislation. We did it all for environmental reasons.”
About 40 people turned out to help with the planting.
An oxbow is an area created when a river meanders and eventually joins up at the narrowest point to create a lake.
Mr Rau said he hoped the planting would become an annual event.
He and his wife Jabe are working with the school to raise seedlings so that each year group can have a similar experience.
“We are continuing to plant riparian areas on our farm which borders the school and other farms in the district,” Mr Rau said.
