Areas of land which are identified as having high sediment yield based on SEDNET the model. The thresholds used in the Waitangi, Mangere and Whangarei catchments are >250 tonnes/km2/yr and >500tonnes/km2/yr in the Doubtless Bay catchment. NB: This dataset is part of the Proposed Regional Plan, July 2017. It has no legal effect. |
