Abstract

Waikato Regional Council has a role through the Regional Policy Statement to protect threatened indigenous habitats and species, safeguard remnant populations of indigenous species, and recreate ecological links for threatened species habitat. To better meet these obligations for biodiversity protection on private and public land, the council began an inventory for all nationally threatened and regionally uncommon species occurring within the Waikato region.
