Freshwater management tools

A web application tool to explore monitoring data and model predictions related to stream and estuary eutrophication

The Fish Passage Assessment Tool has been developed to provide an easy to use, practical tool for recording instream structures and assessing their likely impact on fish movements and river connectivity.

This manual aims to provide the guidance needed to manage mangrove expansion, while maintaining the ecological integrity of estuaries and harbours.

The River Environment Classification (REC) is a database of catchment spatial attributes, summarised for New Zealand's river network. The attributes were compiled for the purposes of river classification, while the river network description has been used to underpin models. 

Wetland species and wetland management in New Zealand.

Management of stream riparian areas - including vegetation and stock access - influences the health of streams and downstream water bodies.

Habitat degradation and the introduction of exotic plant and fish species have adversely affected kōura populations throughout New Zealand. However, there are a number of measures that we can use to restore kōura populations in lakes, rivers and streams.

Shallow lakes are highly valued but often degraded in New Zealand.

Tau kōura is a traditional Māori fishing method commonly used to harvest kōura or freshwater crayfish in areas where they are abundant.
