Lakes water quality: Lake weed and pest animals

Abstract

It is a pleasure to be invited to be part of this. The debate around fresh water in New Zealand has never been so strong and the delight in coming to Rotorua is that so many parts of New Zealand could learn from the experience here of pulling together a sciencebased collaborative approach for progress. Just listening to Professor David Hamilton's presentation, reinforcing how complex these fresh water issues are, signals the progress that has been achieved.
