The Team


Mark Taylor


Mark Taylor has a wealth of experience, 30 years, in New Zealand freshwater ecology. Mark holds a Bachelor of Science degree in Zoology, and began studies on native fish distribution in South Westland in 1984. He was then employed by Fisheries Research Division of the Ministry of Agriculture and Fisheries, and, after 1992, with NIWA (National Institute of Water and Atmospheric Research) as a senior technical officer. Mark has written and co-written scientific papers on a range of fish research topics from planktonic fish distribution in Canterbury's high country lakes, to growth in eels and trout. He has prepared a large number of reports on native and introduced fish distributions in South Island Rivers, and whitebait spawning habitat enhancement. Mark has also developed a national database on whitebait spawning habitats to facilitate their long-term protection.

Mark continued with his interests when he formed Aquatic Ecology Limited (AEL) in 2001. His focus was to provide a specialist company which evaluates ecological issues associated with a range of man-induced activities such as stormwater discharges, irrigation water uptake, catchment development, or a range of other impacts.

Mark has a reputation for pragmatism, and is well-trusted by local authorities at presenting a balanced viewpoint of the environment. In his spare time, Mark served in a voluntary capacity on the Styx River Living Laboratory Trust for five years, and still has a keen interest in this increasingly urbanised catchment.

Malcolm Main


With 30 years experience behind him, Malcolm is an expert in freshwater ecology and water quality. Malcolm has a MSc honours degree and holds a Bachelors degree in both Zoology and Botany. He also has experience in estuarine ecology. Malcolm has written a number of scientific papers on the ecology of New Zealand's native fish, and many reports on water quality and ecology in Canterbury. These include aspects of both chemical and microbiological quality, stormwater, and the effects of buffers strips on water quality.

Malcolm has worked for the Department of Conservation, the Ministry of Agriculture and Fisheries, and worked for 16 years as a Water Quality Scientist for Environment Canterbury. He has also undertaken consultancy work for the Christchurch City Council, other local authorities and farmers.

Malcolm revels in the variety and challenges of environmental science. This could be interpreting the nuances of water quality data, indentifying native fish habitats, or undertaking night surveys, electric fishing or invertebrate surveys.

Malcolm is an enthusiastic outdoorsman, and enjoys hunting, fishing, and boating. He also manages two farms, and understands the challenges of the rural environment, but with an understanding of the associated ecological issues.

Winsome Marshall (née Blair)


Winsome has worked for Aquatic Ecology for five years and holds a Bachelors degree in Biological Sciences. She has a wide experience in field techniques associated with freshwater habitat assessment and is a qualified electric fishing operator. An expert and confident animal handler, Winsome has field experience with fish anaesthesia and identification, as well as experience in handling rare birds and reptiles. She has participated in a survey of the Ashley River, observing wrybills, banded dotterels and other river birds. Winsome has been involved with and co-authored a number of environmental reports relating to instream values and assessments in the Canterbury region.

Frank Burdon


Frank Burdon is a part-time Research Associate for Aquatic Ecology and is a bio-statistician, specialising in complex statistical analysis. His involvement with Aquatic Ecology is centred around analysis of water quality data from trout spawning gravels. He is currently a Research Associate for the University of Canterbury and is undertaking Ph.D. research in aquatic ecology. He graduated with a Bachelor of Science in Zoology in 2001 and a Master of Science (Zoology) in 2004. With over 10 years of experience in ecological research, data analysis and science communication, he is a well-equipped member of the scientific community. Frank became an editor for New Zealand Natural Science in 2011 and is a member of the New Zealand Freshwater Sciences Society (NZFSS), Royal Society of New Zealand (RSNZ) and the Society for Freshwater Sciences (SFS).
