Restoring one million metres worth of waterways

The Million Metres Streams Project has a goal to restore a million metres worth of waterways, by planting native trees along the banks of rivers and lakes across the country. They're almost at the 25-thousand-metre point, so there's still some way to go. The aim is to reduce erosion and sedimentation, and improve water quality. It's something that everyone can get involved in - and this year the project is encouraging people to buy their friends and whanau a bundle of trees for Christmas, instead of opting for a scented candle, scarf or the dreaded pair of socks. Georgina Hart leads the project, and she joins Kathryn Ryan in the studio.
