A guide to sediment trap construction
New Zealand has a significant erosion challenge, with more than 200 million tonnes of soil lost from the land to the sea each year. We can reduce soil loss with careful land management and by installing sediment traps temporarily when soil materials are vulnerable to erosion from activities like earth works, cultivation or when stock is on a winter crop.
Fish and Game New Zealand along with the Royal Forest and Bird Society, the National Wetlands Trust and the Department of Conservation have been fighting hard to protect the remaining wetlands and establish new ones. This website section has useful information on the biological value of wetlands and how to establish them. You can also download these pamphlets:
