University of Otago Emeritus Prof Sir Alan Mark has been awarded the 2010 Charles Fleming Award for Environmental Achievement.
"He is regarded as New Zealand's leading environmental scientist and conservationist," Royal Society of New Zealand officials said in announcing the national environmental science award, which is made every three years.
During his long research career Prof Mark had "explored and illuminated the ecology of southern ecosystems", including tussock grasslands and wetlands, through many highly influential publications, officials said.
Prof Mark, who is already a fellow of the society, said the award was "a great honour" and "something special, coming from the Royal Society".
He was still involved with scientific research and environmental issues and the award would encourage him to keep going as long as he could, he said.
