National Environmental Standards for Plantation Forestry - Erosion Susceptibility Classification and Fish Spawning Indicator Databases. When uploading the layers into your own GIS system, please ensure all three Fish Spawning Indicator layers are uploaded (NZFFD, Non-Migratory and modelled probability) along with the current ESC version layer.This tool was developed for use in the context of the National Environmental Standards for Plantation Forestry (NES-PF). The tool supports councils and foresters in decisions on the level of risk associated with the NES-PF. Its successful application elsewhere cannot be guaranteed.Note the ‘create webmap’ feature within this portal has limited functionality. Please upload all datasets into your own GIS software for analysis purposes. If you do not have access to GIS software, you can use the NES-PF Erosion Susceptibility Classification and Fish Spawning Indicator tool.
