15.1.1 The Waikato-Tainui rohe is home to approximately 170 indigenous bird, mammal, reptile, amphibian, and freshwater fish species. Indigenous animals include the tuatara, pekapeka (long tailed bat), matuku (Australasian bittern), tuna (eel), whitebait, and very rare and endangered species such as native frogs. The rohe is also home to at least 900 known indigenous plant species. The indigenous plant and animal species found in the Waikato are valuable cultural resources, and in themselves serve as kaitiaki and natural indicators reflecting the health of the environment.
15.1.2 Prior to Raupatu, the region was renowned for the abundance of natural resources that lay within the rivers, lakes, wetlands and their catchments, and ngahere (native forests). The alluvial soils, sands and gravels carried and deposited by the rivers provided the beds and materials for Waikato-Tainui maara (gardens). Manu (birds) such as kiwi, kookako, kaakaa, tuuii, kereruu and hihi were found commonly throughout the ngahere. Valued weaving resources such as harakeke, kiekie (Freycinetia banksii), and ngaawhaa (Eleocharis sphacelata) graced many of the riverbanks and wetlands. Furthermore, Waikato-Tainui traditions speak of when the lakes and wetlands teemed with large numbers of tuna (eel), koura, whitebait and kaeo (freshwater mussels).
15.1.3 Post-1840, three-quarters of the indigenous vegetation of the Waikato has been removed to make way primarily for agricultural use. Eight of the nine indigenous ecosystem types found in the Waikato-Tainui rohe (as identified by the Waikato Biodiversity Forum), are threatened by a lack of adequate legal protection, incompatible adjacent land uses and human-related impacts within their catchments. The greatest losses have occurred in the lowland areas (18% indigenous ecosystems remaining); coastal zone (28 % remaining); and sub-montane zones (zones at the base or lower slopes of maunga) (34% remaining).
15.1.4 The loss of habitat and introduced pests (such as ship rats) have been a major reason for the decline and extinction of many native plant and animal species. 223 flora and fauna species are in decline or threatened with extinction in the Waikato Region (source: Waikato State of the Environment Report, 1998). Losing an indigenous species impacts on the whakapapa of the Waikato-Tainui landscape and threatens the viability of Waikato-Tainui culture and traditional activities. Extinctions or declines in a species or habitat have an impact on maatauranga (knowledge) about the ecosystem and environment and the information that can usefully be passed on to future generations.
15.1.5 Today, the Waikato-Tainui rohe provides habitat for at least three nationally endangered animal species: kaakaa, kookako, and the pekapeka (long tailed bat), and a declining species, the giant kookopuu. It is important to Waikato- Tainui that the remaining indigenous species are protected from further depletion and other threats to their wellbeing, and that their populations and habitats are enhanced and/or restored.
15.1.6 The introduction of foreign species into New Zealand ecosystems has also had devastating effects on native species and their habitats. Many of these introduced species are invasive pests (plants, animals, and micro-organisms) that have caused harm to the environment, economy, and/or human health.
15.1.7 Waikato-Tainui culture, tikanga and kawa has evolved with the indigenous flora and fauna of the tribal area. Waikato-Tainui are part of the natural heritage of the land and are at risk when the resources and taonga around them become depleted degraded or destroyed. The continued threat of invasive species to the delicate balance of the indigenous ecosystem is also a threat to the Waikato-Tainui way of life. The prevention of new pests and diseases from inhabiting the natural environment and the removal or reduction of pest species from existing natural areas is necessary to prevent the continued decline of remaining natural areas.
15.1.8 The Waikato Regional Council Significant Natural Areas (SNA ) programme helps to identify terrestrial and wetland habitats across the region. A complementary process could be developed to apply the ‘culturally significant’ wetlands to the SNA baseline and to apply Waikato-Tainui local knowledge to fill gaps (such as for smaller wetlands that are difficult to detect at the regional scale).
15.1.9 Genetic modification (GM) remains a controversial issue both globally and nationally. It is vital that Waikato-Tainui views and policies on the potential adverse consequences of GM are clearly outlined and recognised. Most importantly, Waikato-Tainui wants to avoid any disruption caused by Genetically Modified Organisms to the balance of indigenous ecosystems and/or to cultural beliefs and the whakapapa of taonga species.
Decreased indigenous biodiversity
15.2.1 The size, natural health, and ecological integrity of the remaining indigenous areas of vegetation within Waikato will continue to decline without additional effort to protect, and enhance them.
15.2.2 The loss of indigenous trees and plants from the productive and human-occupied landscape continues to compromise the health of the natural environment by lessening the area of suitable habitat for taonga species, severing the vegetation corridors that are essential for the dispersal of indigenous species, and reducing the contaminant buffering and cleansing function that indigenous vegetation can perform.
15.2.3 A significant number of native flora and fauna species in the Waikato Region continue to decline in abundance and geographic spread. Many of the species facing local and regional decline or extinction are of cultural and spiritual significance to Waikato-Tainui.
Impacts to the relationship between Waikato-Tainui and the environment
15.2.4 Since Raupatu, the impacts of changed land use has gradually depleted the natural and cultivated abundance of Waikato-Tainui resources, undermined the ability to manaaki, or care for our people and manuwhiri, which has consequently weakened environmental whakapapa and hence, the foundations of the relationship of Waikato-Tainui with the whenua.
Landscape planning and compromising of natural heritage
15.2.5 Waikato-Tainui are concerned that inefficient resource development, use, associated activities and infrastructure risks are compromising and depleting the remnants of natural vegetation that remain in the region and serve as a reminder of the original natural character of the landscape.
15.2.6 The indiscriminate use of indigenous plant material not sourced from local plant material (i.e. not eco-sourced) for restoration and development rehabilitation projects continues to alter the natural character of the region and the genetic composition of the remaining natural plant and animal populations. Such use needs to give consideration to strengthening the genetic pool of indigenous species.
15.2.7 Inadequate rural and urban design standards may allow ill-considered designs for dwellings and other structures to be built in areas of high natural character. This further detracts from the mauri of the land and weakens the connection with its natural, cultural, and spiritual foundations.
Biosecurity – plant and animal pests
15.2.8 Several of the 10 exotic fish species found in Waikato rivers, lakes, and wetlands pose a substantial threat to aquatic ecosystems. Koi carp, in particular, causes considerable damage to habitat, degrades water quality, and excludes native fish species.
15.2.9 Control of key vertebrate (animal) pests, such as possums, stoats, and ship rats is mainly concentrated in high priority conservation areas and is somewhat effective in arresting the decline of important threatened bird species. However, due to issues related to limited or poor planning, and/or limited funding and resourcing, pest control is not sufficient in many other areas of indigenous habitat. As a result there is a continued decline in several indigenous species of bird, reptile, frog, plant species, and an unknown number of invertebrates.
15.2.10 Some pests, such as cyanobacteria/blue-green algae, are not appropriately recognised in regional biosecurity and pest management policies despite the impact of this organism on customary practices such as hauanga kai and the associated ability to harvest kai.
15.2.11 Chemical herbicides and pesticides used to control weed and pest species have increasingly been developed to be more effective against target pests, less harmful to non-target species (species that the control agents are not intended to affect) and less persistent. However, some in current use are known to kill non-target species, some bio-accumulate (remain and increase in concentration in the environment), and some remain active in the soil for prolonged periods.
15.2.12 Biological Control Agents are alternatives to chemical control agents and are usually introduced species released into the environment to control another species. There is concern at the potential of biological control agents to affect nontarget species and that they may, themselves, establish as a pest species or a threat to indigenous biodiversity.
New organisms and Genetically Modified Organisms
15.2.13 New organisms continue to be introduced, either intentionally or unintentionally, or developed through genetic manipulation (GMO’s). Until proven otherwise, Waikato-Tainui remains concerned about the potential of these new organisms to attack, compete with, interbreed, or otherwise harm native and taonga species.
15.2.14 Waikato-Tainui also has a vested interest in protecting the economic sustainability of tribal members and/or tribal lands within the primary production sector, and the negative impacts on productivity which can be caused by the introduction of new organisms – whether GMO or otherwise. PSA (kiwifruit), varroa bee mite, and oyster herpes virus are examples of devastating biological outbreaks that risk creating severe economic loss and reduced capability.
