Integrated landscape mapping of water quality controls for farm planning - applying a physiographic approach to the Waituna Catchment, Southland

Living Water (a Fonterra and Department of Conservation partnership) commissioned a high-resolution physiographic assessment of the Waituna Catchment, Southland, to support water quality and biodiversity investment decisions for the catchment. The key process-attribute layers identified for the Waituna Catchment are hydrology and redox. In total there were 19 PGU's defined by combing the H-PAL and R-PAL, each of which are characterised by a unique combination of landscape attributes that mediate land use pressure in a different manner and/or degree.
