Alan Mark, Emeritus Professor of Botany at the University of Otago, is a plant ecologist with interests and involvements in a wide rage of indigenous ecosystems,from high mountains to marine. His main research field has been the pure and applied ecology, and sustainable management of the upland snow tussock grasslands and associated mountain lands, particularly of the South Island high country. Professor Mark had a major involvement in assessing the potential environmental impacts of the proposal to raise the levels of Fiordland’s Lakes Manapouri and Te Anau. This led to his 26-year initiating role as Chair of the Government-appointed Guardians of these lakes to integrate conservation with their hydro-electric development. He is currently a member of the inaugural Fiordland Marine Guardians, overseeing the sustainable management of the Fiords, while also initiating the first southern hemisphere GLORIA (Global Observation Research Initiative in Alpine Environments) monitoring sites here.
