LERNZ hit the road to show how to save lakes
A team of scientists from the University of Waikato is heading on a nationwide road show to highlight what they can do
to save the country's lakes.
LERNZ, the Lakes Ecosystem Restoration New Zealand programme, based at Waikato University and funded by the Ministry of
Science and Innovation, will be travelling the country from Whangarei to Invercargill this February and March, visiting
regional councils to show how their research can help their lakes and waterways.
The scientists have developed pest fish management and monitoring techniques, including trapping and behavioural
removal, genetic identification from water samples, electrofishing and satellite imaging for detecting changes in water
quality.
They've also developed harmful algae bloom management techniques which involve genetic tools for assessing toxin
potential, automated high frequency monitoring buoys, remote sensing of water quality and restoration prototypes for
combating algal blooming.
This is part of a $10 million project over 10 years to research and save New Zealand's lakes.
Research manager Jo Faber says the road show is a chance for researchers to speak to councils about they work they do,
and how it can be put into practise in their area.
"Part of the 10 year project is that we get the end users involved. This means making sure regional councils, iwi and
other parties know about our research and what we can do.
"We don't just want to present the tools we've come up with; we want feedback to work interactively with end users to
clean up their lakes."
Native fish and plants are in decline in most New Zealand lakes, as pest fish and invasive weed out-compete the native
species. Toxic algal blooms have in some cases resulted in water supply closure, cattle deaths and closures of lakes for
recreational activities.
