About this report

Waikato Regional Council commissioned Wildland Consultants to revise the criteria set used for the ranking of geothermal habitats in the Waikato region.

The council's key requirements are that the review is to address the removal of criteria not relevant for geothermal habitats, the removal of any potential “double-dipping” with regards to site scoring, and simplification to ensure that the scoring system can be applied both efficiently and accurately. A key objective of the revision was to also design a single worksheet that includes all of the criteria, to enable the calculation of an overall site score.

This report provides:

  • an overview of the wider regional ranking criteria set.
  • a brief review of the wider regional ranking criteria set, to identify the criteria relevant to ranking geothermal sites.
  • identification of additional or newly-formulated criteria relevant to the ranking of geothermal sites.

It is important that the regional council is able to soundly prioritise potential biodiversity management effort in geothermal areas. These habitats are of very limited extent, occur at more than 60 sites, and many are degraded and/or under considerable threat.
