Biography
Mary is a freshwater ecologist based at NIWA in Hamilton and manager of the Aquatic Plant Group – a team of researchers working on vegetation aspects across varied aquatic systems. Mary has more than thirty years expertise in aquatic plant ecology, surveys and management. As a scientific diver, Mary is very familiar with a wide range of freshwater environments and underwater survey techniques. She is experienced in carrying out ecological surveys and regularly runs large monitoring programs for environment reporting purposes. A focus of Mary’s research is the management of aquatic weeds within the wider framework of freshwater biosecurity. Current research projects include monitoring of weed control operations to explore trade-offs between impacts and benefits along different timescales. Mary frequently provides operational advice to agencies for aquatic weeds. On the flip-side, Mary is also involved in research aimed at restoring native submerged species to degraded waterways.
