Tools and guidelines for managing ecological health

Guidelines, tools and protocols for managing the ecological health of rivers, streams, lakes, wetlands and groundwater resources in New Zealand. 

All fresh waters

Biophysical Ecosystem Health Framework
Describes a framework for the integrated assessment of the biophysical ecosystem health of freshwater. Applicable to all freshwaters, the report describes an example of its application in rivers.

National Environmental Monitoring Standards [NEMS website]
Monitoring and data acquisition practices for a growing range of common indicators such as water quality, turbidity and dissolved oxygen. 

Rivers and streams

The New Zealand stream health monitoring and assessment kit [NIWA website]
Consists of a user guide and equipment for monitoring that enables users to collect scientifically robust data on stream health.

A user guide for the macroinvertebrate community index
Advice on appropriate application of the MCI in different stream environments, design of monitoring programmes and data analyses.

Protocols for sampling macroinvertebrates in wadeable streams
Identifies and describes standardised protocols for macroinvertebrate biomonitoring.

Macroinvertebrate metrics for the National Policy Statement for Freshwater Management
Advice on macroinvertebrate attributes for assessing ecosystem health.

Guidelines for sampling freshwater fish [NIWA website]
Overview of guidelines describing how to sample freshwater fishes in New Zealand. Provides links to key documents.

Fish passage management [DOC website]. 
Advice about managing fish passage. Contains links to the New Zealand Fish Passage Guidelines, and the Fish Passage Assessment Tool.

Sediment assessment methods [Cawthron website]
Guidelines for assessing the effects of deposited fine sediment on in-stream values.

Lakes

(LakeSpi) Lake Submerged Plant Indicators [NIWA website]
Guidance and methods

Protocol for monitoring trophic levels of New Zealand lakes and reservoirs
It specifies a cost-effective method to determine the trophic levels of lakes and changes in these levels over time.

Lake manager's handbook: Fish in New Zealand lakes
Information on native and exotic fish populations in substantial lakes and reservoirs.

Lake manager's handbook: Lake-level management
Information on lake levels, lakeshore erosion and marginal vegetation.

Lake manager's handbook: Alien invaders
Information on pest fish and weeds in New Zealand lakes.

Lake manager's handbook: Land-water interactions
Information on the relationship between water quality in lakes and the processes in the surrounding catchment.

Draft guidelines for the selection of methods to determine ecological flows and water levels
Scientific guidelines for the selection of methods to determine ecological flows and water levels for rivers, lakes, wetlands, and groundwater resources.

Wetlands
