Biophysical Risk Mapping Manual and Methodology – Bay of Plenty

CLIENT: The Bay of Plenty Regional Council (BOPRC)

EXPERTS: Istvan Hadju, Glen Treweek, Aimee Dawson, Electra Kalaugher (WSP)

About this resource

The Bay of Plenty Regional Council (BOPRC) sought advice to develop risk maps for four main contaminants (nitrogen, phosphorus, sediment, and E. coli) to support their land managers in targeted conversations with landowners on potential mitigation opportunities. Using empirical datasets such as LiDAR, soils, slope, and waterways, WSP provided regional council staff with spatial tools and a replicable methodology to identify high-risk areas for contaminant loss and guide on-farm actions to meet freshwater management targets. Outputs included biophysical contaminant risk models and a methodology guidance document (PDF, 1.07 MB), providing regional councils and land managers with practical tools to address water quality challenges while promoting sustainable land-use practices.

This project was co-funded by Access to Experts and BOPRC.
