Owl Farm case study - Wetland performance
See how Owl Farm's constructed wetland strips nitrogen and sediment from farm runoff.

This page from Owl Farm, a demonstration dairy farm in the Waikato, covers the stock-excluded trees, scrub, wetland and native plantings across its landscape. It reports on Ecoblitz surveys carried out by Lincoln University in 2015 and 2017, which recorded hundreds of bird, insect, plant and mammal taxa on the farm and surrounding school campus.
It also covers the farm's Integrated Planting Plan and its partnership with St Peter's School students, who pot up a thousand native seedlings a year through the Trees for Survival programme.
