LERNZ Lake Ecosystem Restoration New Zealand
Linking lake restoration research with end users to achieve outcomes.
- 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.
