Duncan Gray undertook training and research with the Fresh Water Ecology Research Group at the University of Canterbury. His primary area of interest was the ecosystem function of braided rivers focussed primarily on macroinvertebrates, but including fish, groundwater and terrestrial components of food webs. Duncan has also worked in streams impacted by Acid Mine Drainage. Subsequently, he spent time consulting with Golder Associates working on environmental flows and macroinvertebrate monitoring protocols.
Since 2014 he has been working for the Canterbury Regional Council with a broad remit providing science advice to planning, consents and implementation as well as undertaking discrete investigations to inform that advice. Duncan has an ongoing interest in braided rivers, but strongly suspects that the ‘science to inform management’ has matured while the socio-political beast is dragging the chain.
Braided rivers and their floodplains are an iconic feature of the Canterbury landscape. In their natural state, they encompass a complex and dynamic range of aquatic, wetland and terrestrial habitats with very high value for indigenous biodiversity. However, the natural character of Canterbury braided rivers is under threat from woody weed invasion, agricultural encroachment and engineering works. The current state of braided rivers in Canterbury presents a management conundrum and forces a consideration of what as a society is important.
