Keynote Speakers

The Biennial Scientific Conference on the Greater Yellowstone Ecosystem typically includes named lectures in honor of notable influences Aubrey L. Haines, past Yellowstone National Park historian, and A. Starker Leopold, a shaper of national park policy. A third lecture named for Yellowstone's superintendent invites an international leader in conservation to speak about some global aspect of park science and management. A complete description of the named lecture series is available here:

The goal of the named keynote speeches is to provide some broadening from the focus of the conference, and expose conference participants to a wide-ranging selection of important topics.

Confirmed Speakers

A. Starker Leopold Lecture -- Estella B. Leopold
The A. Starker Leopold Lecture is the "centerpiece" keynote of the conference series and is named for A. Starker Leopold (1913–1983), ecologist, conservationist, and educator, who was a primary force in the shaping of modern national park policy.

Dr. Estella B. Leopold will deliver the A. Starker Leopold Lecture at the 11th Biennial Scientific Conference on the Greater Yellowstone Ecosystem. She is a University of Washington professor emeritus of botany, forest resources and quaternary research, and has been teaching and conducting research for more than 60 years.

The author of over 100 scientific publications in the fields of paleobotany, forest history, restoration ecology and environmental quality, Dr. Leopold pioneered the use of fossilized pollen and spores to understand how plants and ecosystems respond over eons to such things as climate change. Her work at the Florissant Fossil Beds in Colorado made the case for the necessity of their preservation, an achievement which contributed to Dr. Leopold’s receipt of the prestigious International Cosmos Prize in 2010. She was elected as a member of the National Academy of Sciences in 1974. (Credit and for more information: The Aldo Leopold Foundation,

Aubrey L. Haines Lecture -- Paul Schullery
The Aubrey L. Haines Lecture is delivered by distinguished figures in their specialty and is named for Aubrey L. Haines (1914–2000), who participated in shaping the park’s history for nearly 60 years and remains the premier historian of Yellowstone.

Paul Schullery first worked in Yellowstone National Park as a ranger-naturalist in 1972, and throughout his career held a variety of positions in the park, including historian archivist, technical writer, senior editor in the Yellowstone Center for Resources, chief of cultural resources, and environmental protection specialist. He holds a B.A. from Wittenberg University and an M.A. from Ohio University in American history, and an honorary doctorate of letters from Montana State University. Paul is the author, co-author, or editor of 40 books about nature, conservation, history, and outdoor sport, including 10 books about Yellowstone. He has authored a series of books about the history, natural history, and cultural complexities of the sport of flyfishing. He is the recipient of numerous awards and honors, including the Wallace Stegner Award, given by the University of Colorado Center of the American West for “a sustained contribution to the cultural identity of the American West.” In 2002 he wrote and narrated the ABC/PBS film Yellowstone: America’s Sacred Wilderness, for which he received Wildscreen International’s Panda Award for screenwriting. He was also an advisor for and appears in the recent Ken Burns film The National Parks: America’s Best Idea. For more information, visit

Superintendent's International Lecture -- Ian Dyson
The Superintendent's International Lecture is delivered by a leading figure in international conservation on some global aspect of park science and management.

Ian Dyson is a geographer and planner with 30 years of experience dealing with integrated resource management water resources, protected areas, land use, and regional sustainable development plans in Alberta, Canada. His experience has been particularly focused on building multi-stakeholder partnerships dealing with approaches to address environmental cumulative effects including the conservation of prairie and parkland biodiversity, water quality in the Oldman River Basin, and trans-boundary collaboration to sustain ecological health in the Rocky Mountains.

As a pioneer of partnerships and cumulative effects, Ian is currently responsible for advocacy and challenging thinking to help ensure that the Government of Alberta’s efforts to transition to an environmental management system capable of managing cumulative effects become an operational reality.

In 1999, Ian was awarded a prestigious Emerald Award for Corporate and Institutional Leadership by the Alberta Emerald Foundation and he received the Prairie Conservation Award in 2001.
