Description: Soil stability data layer showing unstable points for the Waikato Region.  Data source is from Waikato Regional Council technical report 'TR21-30 Soil stability in the Waikato Region 2007-2017'.  The data for these points is shown on Figure 6 of the report.

Points classified as e - eroding unstable surfaces (freshly disturbed, bare) contain surfaces that are actively eroding and show evidence of freshly disturbed soil. The West Coast zone had the highest proportion of points that were classified as ‘actively eroding – e’ (19%) – followed by Lake Taupō (12%), Waipā (12%), Lower Waikato (9%), and the Coromandel (8%). The Upper Waikato, Waihou-Piako, and Central Waikato CMZs had less than 7% of points that showed evidence of active erosion. In terms of risk for future erosion events, the West Coast management zone had the highest risk due to the soft rock geology and steep slope classes. Erosion risk may be further exacerbated by high storm frequency and rainfall intensity, both of which are likely to increase with climate change.
