FRESHWATER SPECIES, HABITAT QUALITY, ECOSYSTEMS
|
- Actions implemented to correct decline in freshwater species, habitat quality or ecosystems.
|
|
|
- 80% of rivers/streams and lakes (other than lowland streams) with very good aquatic ecosystem health.
|
|
RIVER MOUTH AND COASTAL LAGOONS
|
- Actions implemented to prevent further loss of ecosystem health in river mouth and coastal lagoons.
|
|
- Protection/restoration programmes on most ecologically significant river mouths or coastal lagoons.
|
- Examples of thriving coastal lagoons in each zone and lowland or spring-fed ecosystems in each zone.
|
|
INTERMONTANE BASIN AND PLAINS AQUATIC AND DRYLAND ECOSYSTEMS
|
- Existing high quality of indigenous ecosystems maintained.
|
|
|
- Maintain upland spring-fed streams and lakes in very good aquatic health (no decline from 2010).
|
|
LOWLAND STREAM ECOSYSTEMS
|
- Best examples of lowland streams identified and prioritised for protection.
|
- Ecological health of the best examples of lowland streams protected and enhanced.
- Improved ecosystems in at least another 10% of lowland streams in each zone.
|
- Improved condition and water quality in at least 60% of lowland streams and lowland lakes.
|
- Examples of thriving lowland or spring-fed ecosystems in each zone and lowland or spring-fed ecosystems in each zone.
|
|
HIGH COUNTRY SPRING-FED FOOTHILL RIVERS / LAKES
|
|
- Identify streams with declining ecosystem health, assess cause and develop action plan.
|
- All foothill and high country rivers and/or lakes in good ecological health (or better) or showing an upward trend.
|
|
|
GENERAL
|
- Prevent further loss of naturally occurring wetlands.
|
- Protect all and restore at least two significant wetlands in each zone.
- Implement remedial actions where there are inadequate environmental flows to meet ecosystem health / biodiversity outcomes .
- Identify areas not meeting catchment load limits, prioritise areas and implement actions to ensure no further enrichment.
- Demonstrate and include in implementation programmes how land will be managed to achieve catchment load limits.
- Understand emerging contaminant risks and target at risk areas.
|
- Protect all existing wetlands.
- Length of waterway with riparian management (for aquatic ecosystem protection) increased by 50% from 2010 figures.
- Progress towards environmental flow and catchment load limits.
|
- Protect all wetlands.
- Achieve nutrient efficiency targets on all new irrigated land and 100% of other rural properties (and properties within urban boundaries that apply nutrients over significant areas).
- Achieve all environmental flow and catchment load limits.
- Understand emerging contaminant risks and target at risk areas.
|
|
IRRIGATED LAND
|
|
- Achieve nutrient efficiency targets for the zone on all new irrigated land and 50% of other rural properties (and properties within urban boundaries that apply nutrients over significant areas).
|
- Achieved nutrient efficiency targets for the zone on all new irrigated land and 80% of other land in major rural land uses and have 100% of rural properties (and properties within urban boundaries that apply nutrients over significant areas) working towards these targets.
|
|
|
TROUT & SALMON
|
|
- Increasing annual trout spawning counts in identified important areas as an indicator of available habitat for salmonid and indigenous fish species.
- No further reduction in the number and areas of existing salmon spawning sites.
|
|
|
|
WAIHORA/LAKE ELLESMERE AND TRIBUTARY STREAMS
|
|
- Accelerate the riparian restoration and management programme.
|
|
|
|
NATIVE FISH
|
|
|
- An upward trend in diversity and abundance of native fish populations.
