Assessment of ecological information available for geothermal sites in the Waikato region

Abstract

Geothermal ecosystems are some of the most threatened in the Waikato Region, having undergone significant reductions in extent and condition. Five geothermal ecosystem types have been recognised in New Zealand and these are all considered to have been naturally rare prior to human colonisation of New Zealand (Williams et al.2007). Additionally, these are all identified as Critically Endangered in Holdaway et al. (2012). Waikato Regional Council (WRC) has an inventory of geothermal sites in the Waikato Region, which contains a summary of ecological information and assessments of ecological significance and relative significance level (Wildland Consultants 2014a; also see Wildland Consultants 2014b&c). 

WRC recently developed and applied simple and accurate indicators to assess the extent, condition, and protection level of geothermal vegetation and habitats in the Region (Wildland Consultants 2015). This project identified that there were gaps in some of the existing ecological information available for each site.
