Native freshwater plants in New Zealand include species and assemblages found nowhere else, but these are under threat from invasive introduced weeds and fish, from decreasing water quality, and destruction of habitat.
NIWA applies molecular and standard taxonomic techniques to recognise endemic or unique aspects of our submerged flora. To restore native freshwater vegetation we identify methods to deliver the habitat requirements for native plants. NIWA’s studies on ecology of rare and endangered aquatic plants advances strategies to protect or enhance their populations.
