Safeguarding New Zealand’s waterways is the key driver behind a seven-year study into the performance of control practices for reducing erosion and sediment delivered to rivers from forest harvesting.
The Ministry for Primary Industries (MPI) has partnered with a forestry company, OneFortyOne New Zealand, providing $1.37 million through its Sustainable Food and Fibre Futures fund to the $3.6 million project.
The project is in its second year, with a long-term monitoring programme now established within control and treatment catchments at OneFortyOne’s Donald Creek Forest, near Tadmor in the Tasman district.
“We want to find out what erosion and sediment control measures work best, and we can only know this through robust real-world studies,” says Steve Penno, MPI’s director of investment programmes.
“This project is exploring the effectiveness of current best practice in sediment control as well as some new innovations. Later in the project, the researchers will construct a large sediment retention pond to see how that measures up compared to traditional methods.
“As well as the benefits of erosion and sediment control, the programme will also compare the costs of different practices.” Continue reading
