Students first tested the health of Horne Creek, which runs through central Queenstown, and learned how human activity can impact it.
Two classes then joined with the local council on a programme of planting the creek’s banks.
A third class chose to educate the community about the creek.
They created posters promoting Otago Regional Council’s (ORC) pollution hotline that were collated into a design for the back of an Orbus bus that was launched last week.
Local-based regional councillor Alexa Forbes is grateful for the students becoming ‘the voice for water’ — "protecting water is difficult, because so many things put it under threat".
ORC compliance manager Tami Sargeant’s delighted the students "gave us an opportunity to work together to remind the community we need everyone’s help to protect this valuable, but vulnerable, taonga".
