The Erosion Susceptibility Classification (ESC) is used to identify the susceptibility of land to erosion and then to set regulatory thresholds for various plantation forestry activities. The ESC is based on the analysis of potential and present erosion data associated with the NZ Land Resource Inventory and classification of Land Use Capability (LUC) units. This revision extends the ESC to cover all of New Zealand, revises the ESC class of some LUC units, allows identification of ESC units dominated by gully, tunnel gully and earthflow erosion, and identifies all polygons containing class 8e land.This dataset has been prepared to support the National Environmental Standard for Plantation Forestry. The ESC is used to identify the susceptibility of land to erosion which is used as the basis for setting resource consent requirements for various plantation forestry activities on different types of land. The ESC is based on the New Zealand Land Resource Inventory (NZLRI).
