Invertebrate macro-fauna in geothermal soils under native vegetation in the Waikato region

On this page: Abstract, table of contents

Report: TR 2013/32

Author: B Willoughby (Ecometric Consulting Ltd) and C Beard (Waikato Regional Council)

Abstract

The Waikato Regional Council has, through the process of identifying significant natural Areas (SNAs), created an inventory of natural habitat in the Waikato region. Geothermal vegetation is mapped into three broad categories:

  • non-vegetated raw soil field
  • emergent wet land,  and
  • terrestrial vegetation.

This report details a survey that was designed to provide baseline descriptive information of soil macro-fauna under native vegetation in geothermal soils in the Waikato region. A ranking system was also explored to rate the quality and disturbance (human induced) at individual geothermal sites.
