This manual aims to provide the guidance needed to manage mangrove expansion, while maintaining the ecological integrity of estuaries and harbours.
Until recently little was known about the effects of mangrove removal on the environment or the best practices for mangrove removal to minimise or avoid adverse impacts and achieve desired removal results. To address this knowledge gap NIWA has surveyed mangrove removal sites throughout the upper North Island.
Many methods of removing mangroves have been used in the past with varied success. The manual provides guidance on each technique alongside advice on where mangrove removal is unlikely to achieve the desired outcome, or is very likely to be very costly to maintain in a mangrove-free state.
