LERNZ Lake Ecosystem Restoration New Zealand

Linking lake restoration research with end users to achieve outcomes.

The LERNZ programme is a series of projects that aim to restore indigenous biodiversity in lakes by developing:

  • New models and technologies to effectively manage harmful algal blooms.

 

  • New pest fish management and control technologies.


  • A city retrofit model


The aim of LERNZ is to identify and remediate threats to lake ecosystems. Through better knowledge of these threats and ways to manage them, improved methods for lake restoration can be developed.
