Our region before 1840

Before European settlement, the Waikato region was covered in native vegetation (except for open water and areas of bare lava or permanent snow and ice).

Although the vegetation was native, not all of it was original. Almost half of the region, mainly the lowlands and the volcanic plateau, had been burnt off and was covered in scrub.

Higher, wetter, or less accessible areas remained in mature kauri, beech or podocarp forest (podocarps include rimu, totara and kahikatea). Native dune vegetation (pingao and spinifex) was found on the coast, especially at harbour mouths and river deltas. There were vast freshwater wetlands near the Lower Waikato River and Hauraki Plains.

The region supported unique plants and animals, with many plants, birds, reptiles, frogs, insects and snails.

Land mammals were rare - only three species of bat. The exact number of land species present in 1840 is unknown, although we do know that some species were already extinct by then, including species of moa and the giant eagle

The current state

The Waikato region is still home to many native plants and animals. We have:

  • more than 900 native plants
  • 124 native bird species
  • 19 reptiles (including geckos, skinks and tuatara)
  • two species of native bats
  • two native frogs.
  • Our streams and rivers are also home to many types of fish and invertebrates.

Several native species are unique (endemic) to the Waikato region:

  • Archey’s frog is only found in Whareorino Forest (south west of Te Kuiti) and in the Coromandel Range.
  • Te Aroha and Moehau stag beetles
  • Mercury Island tusked wētā
  • Mahoenui giant wētā.
  • and some unique snails and beetles associated with limestone habitat.  

We also have unique plant species:

  • Awaroa koromiko/hebe (Veronica scopulorum) on the limestone of the West Coast.
  • Wetland bog plants - Swamp Helmet orchid (Corybas carsei) and the giant wire rush (Sporodanthus ferrugineus) and its associated moth 'Fred the thread' (Houdinia flexilissima) 
  • Many plant species found in our geothermal areas are common only in the Waikato. These include some ferns that are usually associated with tropical areas.

But now around only 27 per cent of our region (approximately 676,863 ha) remains in native vegetation, and at least 300 species of our native plants and animals that live there are threatened with extinction. This includes all our bats and frogs and 40 per cent of the birds and around 1 in every 5 native plant species in the region.

Native forest covers 19 per cent of the region. Scrub, wetland, dune, geothermal, and tussock vegetation make up the remaining native vegetation. Most of today’s native vegetation occurs in the hill country. In the vast lowland area, only 18 per cent of pre–European vegetation is left.

Within our region, vegetation has not been cleared evenly. Some types of vegetation remain in similar proportions to their 1840 extent. For example, the extent of some high altitude vegetation types, such as beech forest, is largely unchanged.

But in other areas, little remains of the original vegetation, for example:

  • Mature kauri forests were heavily logged.
  • Extensive wetland areas have been drained for farming and only 25 percent of the original wetlands remain.
  • Large areas of sand dune were converted from native spinifex and pingao communities to pine plantations. Introduced plants, such as marram grass, have invaded many of the dunes.

The rate of land clearance in the Waikato region has slowed. Now the greatest threat to our native species comes from introduced species such as possums, rats and stoats. These pests have become established in all of our mainland forests. 

Extent and distribution of native vegetation

Areas of native vegetation can be divided by bioclimatic zone or by administrative district. In our region, people have removed much of the native vegetation from lowland and coastal zones. Some other zones are largely unaffected. In some districts a high percentage of native vegetation remains, in others natural areas are scarce.

What's being done?

  •  Waikato Regional Council is helping to protect our natural areas and biodiversity.

    • We work with district and city councils to protect areas of native vegetation through education, regulation and funding support.
    • Waikato Regional Council’s Natural Heritage Fund was established in 2005 to protect and manage, in perpetuity, special places of ecological significance. Key priorities include the preservation of access to waterways and the coast, as well as protection of biodiversity, heritage sites and landscapes of significance to the community.
    • We support care groups undertaking activities to enhance native biodiversity in the region.
    • Waikato Regional Council and Department of Conservation possum control operations target ‘at risk’ areas of native forest.The Department of Conservation also has active management programmes to protect threatened species in our region.
    • We track changes in the indigenous coverage of protected areas. This supports our knowledge base of the extent of the region's biodiversity and helps with policy making and resource consent decisions.
    • We support landowners in the region to covenant special areas on their property to enhance native biodiversity and to provide long term protection.
    • We aim to raise people’s awareness of the environment so that people understand that the daily actions in their lives and business can affect the environment, and learn what actions they can take to improve their own local environments.
