3.2 Diverse plants and animals in lakes and rivers The Lake and rivers support a wide range of ecosystems and natural habitats for native and introduced flora (plants) and fauna (animals).
What does the community want to achieve?
What is currently happening to manage this value?
•
This value recognises the emphasis on aquatic biodiversity for both Lake and river/stream waters. While there are some existing policies there may be further policies developed if a possible National Policy Statement on Biodiversity is prepared. EW has negotiated a Clean Stream Accord with Fonterra for dairy farms to fence waterways and wetlands. The Regional Pest Management Strategy addresses some pest fish species.
•
No net loss of aquatic diversity or habitat for native and desirable introduced flora and fauna Lake and rivers support a diverse range of natural habitats for plants and animals.
What are the main threats to diverse plants and animals in lakes and rivers? •
•
Water pollution: • from nutrient enrichment from farming (run-off into the Lake and stock in waterways) fromsewage • nutrient enrichment impacts on invertebrates (rivers and streams).
•
Quality of life impacts: • invasive pests and weeds.
Key existing Policy documents/actions include EW • Biodiversity Strategy • Asset Management Plan - Lake Taupo Catchment Control Scheme • Clean Streams Project • Regional Pest Management Strategy. DoC • Conservation Management Strategy • Tongariro National Park Management Plan.
Environmental values
Loss of habitat and desirable species: • animal and plant pests threaten native vegetation and desirable fish/bird and invertebrate species • introducing new species affects ecological processes such as food web and the distribution of species drainage of wetlands.
