Location of areas for the purpose of applying rules around the exclusion of Livestock from waterways within Northland. This dataset was known as 'Livestock exclusion areas' in the Proposed regional plan, July 2017. This is the same dataset with a few changes as a result of the submission process, August 2018.

An inventory of five physical factors (rock type, soil, slope, present type and severity of erosion, and vegetation).

A Land Use Capability (LUC) rating of the ability of each polygon to sustain agricultural production, based on an assessment of the inventory factors above, climate, the effects of past land use, and the potential for erosion.

Second edition NZLRI regional upgrades at a scale of 1:50,000 have been completed for Northland, Wellington, Marlborough and Gisborne-East Cape. Third edition NZLRI layers contained a restructured polygon attribute table to allow the core NZLRI to complement the newly created fundamental soil layers with minimal duplication.</SPAN></SPAN></P><P STYLE="margin:0 0 7 0;"><SPAN><SPAN>The appropriate scale of use is 1:50,000</SPAN></SPAN></P><P><SPAN /></P></DIV></DIV></DIV> |

<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>The multi-factor, homogenous unit area mapping, method tends to result in themes being delineated at lower resolution than a single factor map of equivalent scale.
