Dairy farmers’ wetlands work takes to the skies
No one can say that the owners of a dairy farm near Wairarapa Moana can’t see the wood for the trees. After being knee-deep at ground level over the past few years constructing their large-scale wetland project, they are now taking a bird’s eye view using a drone. The drone is helping to map the wetland area, measure the biomass accumulation to better understand carbon sequestering opportunity, and allow the farmers to clearly see which of the many thousands of different native species they have planted is thriving. One of the six shareholders at Kaiwaiwai Dairies, Aidan Bichan, says planting and maintaining wetland areas is a constant learning curve for anyone, including dairy farmers. “Not all species are created equally resilient – and nor is the soil type, land contours and even the water flow the same on any given farmland,” he says. “Using the drone gives us footage that allows us to readily see what species are doing well, but also see where there’s a problem, such as areas being affected by invasive species like blackberry.” But there have also been other learnings for Mr Bichan and his fellow owners. “For example, we planted the wrong species in the wetland water channel. We planted club rush there a couple of years ago and it grew so well it clogged the channel. We recently brought in a digger to rip out the rush and we’ve now replanted that area with raupo.” The drone filming at the farm has been taking place this week in the lead up to World Wetlands Day on Sunday (February 2), celebrated each year around the globe to draw attention to the importance of looking after wetland areas, both on farms and other locales. DairyNZ’s environment manager Aslan Wright-Stow says a wetland is an area of […]
