Dr. Kevin Collier
Leader of the Large Rivers Group
Kevin Collier holds a joint position with The Waikato Regional Council and the Environmental Research Institute at the University of Waikato. His work at the university is focussed on the ecology of large rivers, in particular the Waikato River. He aims to provide information that enables effective ecological monitoring and underpins future restoration work. Kevin co-ordinated a national survey of large rivers in association with collaborators at Cawthron Institute, to test the responses of macroinvertebrate and functional indicators to human pressures, and continues his involvement in several ongoing studies on the Waikato River. He was senior editor of The Waters of the Waikato : Ecology of New Zealand’s longest river, a contemporary synthesis of ecological knowledge of the Waikato River below Taupo Gates, involving over 45 authors and jointly published by the regional council and the university. Kevin was also senior editor of a book synthesising information on the ecology of New Zealand stream invertebrates.
Kevin’s other research interests include the ecology and restoration of urban streams, and the use of macroinvertebrates as indicators for biological monitoring. Kevin is on the Editorial Board of Freshwater Reviews, and is Associate Editor of Freshwater Science (formerly Journal of the North American Benthological Society) and Aquatic Conservation: Marine and Freshwater Ecosystems.
