Summary
Greg Leach is a botanist whose research has been on the plant families Myrtaceae, Mimosaceae and Eriocaulaceae, and on threatened species management and traditional medicinal plants. For over ten years he was in Papua New Guinea. Here he undertook forest surveys, studied mangrove ecosystems and freshwater macrophytes, and added significant numbers of herbarium specimens to the Lae Botanic Garden. In 1985 he became Senior Botanist at the Northern Territory Herbarium in Alice Springs; when this collection was transferred to Darwin in 1989, Leach also relocated. This added arid environments to his research. Since 1997 he has been the Oceania Representative for the United Nations Convention on International Trade in Endangered Species (CITES). Leach is a University Fellow in the Research Institute for Environment and Livelihoods at Charles Darwin University, and an Honorary Fellow in the Child and Maternal Health Division, Menzies School of Health Research in Darwin, focusing on the application of traditional medicinal plants.
