Researchers and Staff

The Centre for Conservation Research was launched in 1999 when the Zoo decided to increase its commitment to conservation through scientific study. Since that time, the Centre has developed a dynamic team that conducts and facilitates conservation research in Canada and around the World. The researchers and staff at the Centre come from a diverse range of backgrounds, but have one thing in common – a passion and commitment towards the conservation of our world's biodiversity.

Head of the Centre for Conservation Research

Over the last 20 years Dr. Axel Moehrenschlager has worked on the conservation and reintroduction of numerous endangered species and in recent years on the integration of science and community based conservation. After years of conservation studies relating to endangered swift foxes on the Canadian prairie he moved to England where his research culminated in a Ph.D. from Oxford University’s internationally acclaimed Wildlife Conservation Research Unit. After joining the Calgary Zoo in 1999, Axel founded the Centre for Conservation Research in 2003 which focuses on the reintroduction of iconic endangered species and the science of community-based conservation internationally. Axel is an adjunct associate professor at the University of Calgary, a graduate faculty member at the University of Guelph, and a senior research associate at Oxford University. He serves on a number of species or thematic committees nationally and internationally and since 2010 he chairs the North American & Caribbean section of the Swiss-based International Union for the Conservation of Nature (IUCN). Passionate staff, dedicated graduate students, and strong national/international collaborations have now yielded an award-winning conservation research team for the Calgary Zoo that uses science to make a positive difference in the world.



Lea Randall

Conservation Research Population Ecologist

Lea joined the Centre for Conservation Research in 2011 and leads the Northern Leopard Frog program.  Her research focuses on the population dynamics of Northern Leopard Frogs and improving survey techniques for this at-risk species.  Prior to this, she worked on a variety of projects for the Yukon Department of Environment, studying organisms such as bats and other small mammals, pine marten, wolverines, and insects. She received her BSc in Biology from the University of Victoria in 2006 and an MSc in Ecology from the University of Calgary in 2009. She has a keen interest in engaging the public in wildlife and conservation issues.

Jill Hockaday
Conservation Research Coordinator

Jill joined the Centre for Conservation Research in April 2008. Before joining the CCR, she completed a B.Sc. in Geography from the University of Calgary. Her background also includes Communications in the areas of agriculture, food and environment. In addition to providing administrative and coordination support for various Research projects within the Centre, Jill is charged with the task of relaying the Conservation Research message to the general public in a creative and engaging manner. Jill is also a member of the Canadian Black-footed Ferret Recovery Communications Team.


Donna Sheppard
Wechiau Hippo Sanctuary Advisor

Donna has joined the Centre for Conservation Research through collaborationwith the Zoo’s Conservation Outreach Department.  The two departments are pursuing a publication partnership aimed at documenting evidence of success in community based conservation initiatives such as the Wechiau Hippo Sanctuary. Through the Conservation OutreachDepartment, The Calgary Zoo provides financial and technical support to a number of responsible Canadian and international conservation initiatives.  The Wechiau Hippo Sanctuary is an exemplary international grassroots enterprise deserving of this outreach support. Donna has been with the Conservation Outreach Department since 1999, working with some of the Zoo’s international conservation partnerships. As a result, Donna spends very little time on Canadian soil. During her first international placement with the Zoo, she spent 4 years at the Guyana Zoo in South America as part of the Calgary Zoo’s sister zoo program. Then in 2004, Donna moved to Ghana, West Africa to be an advisor to the Wechiau Community Hippo Sanctuary. More recently, Donna’s role was expanded to include technical and research support to similar communal conservation approaches in Ghana involving the Western sitatunga and the West African manatee. Donna holds an MA in Physical Anthropology from the University of Calgary where she studied the comparative ecology of redtail monkeys living in logged and unlogged forest compartments in Uganda, East Africa.

Jana McPherson
Conservation Ecologist

Dr. McPherson is a conservation ecologist interested in documenting, understanding and mitigating human impacts on the distribution of individual species, biodiversity and ecosystem function.  She joined the Centre for Conservation Research in January 2000 to assist an assessment of the socio-economic and biological outcomes of the Wechiau Hippo Sanctuary, a zoo-supported community-based conservation initiative in Ghana.  Her expertise lies in modelling the occurrence and abundance of species in space and time, and in developing tools and protocols to analyse data that challenge the assumptions underlying most conventional statistical methods. She is currently applying these skills to an analysis of human impacts on the composition of reef fish communities in the Pacific islands, work she began prior to joining the Calgary Zoo during postdoctoral studies at Dalhousie University.  Her doctoral studies at the University of Oxford examined how distribution models based on satellite-derived environmental data could enhance field observations of birds in southern and eastern Africa, and thus contribute to the conservation of that region’s more than 1,500 avian species.
Tara Stephens
Population Ecologist

Tara has a BSc in Biology from the University of Guelph, an Advanced Diploma in Geographic Information Systems (GIS) from the Centre of Geographic Science, N.S. and recently completed her MSc in Conservation Biology at the University of Calgary. She has worked as a field biologist studying insect behaviour, forest ecology and small mammal population dynamics. Tara joined the Centre for Conservation Research as the lead field biologist and ecological modeller to assist in the development of new understanding of key ecological factors that affect prairie dog and ferret population dynamics in Grasslands National Park. This research will be pertinent to the recovery of one of North America's most endangered species and the conservation of Canada's only prairie dog ecosystem.
