Prof. Phoebe Barnard

Phoebe Barnard
BSc Hons (Acadia, Canada),
MSc (Wits),
PhD (Uppsala, Sweden)

Executive Director,
Pacific Biodiversity Institute

Affiliate Professor, University of
Washington at Bothell


Phoebe’s work is focused on species in real-life ecological and organizational landscapes - why some species are more vulnerable to environmental change than others, what birds can tell us about ecosystem health and human well-being, how species move across fragmented landscapes in response to climate and land-use change, and how we can best help them persist through the gauntlet of the next few difficult centuries. Her work spans the science/ policy/ planning/ implementation arenas of biodiversity and climate change. Through collaboration, she also forays into how species behave in the virtual landscapes of forecasting and hindcasting models of climate and land use change.  

At the Fitz from 2008-2017, Phoebe led a joint UCT/SANBI research team on global change and conservation biology of fynbos endemics, using biogeography, behavioural, evolutionary, population, molecular and stress ecology in order to understand bird vulnerability in real-life and virtual landscapes. She also established, with the late Phil Hockey and then with Peter Ryan and postdoc Dayo Osinubi, the Fitz’s research program on intra-African bird migration. As affiliate professor at the University of Washington and executive director of the Pacific Biodiversity Institute, Phoebe is now applying the ‘biodiversity early warning systems’ approach to evidence-based decision-making that she led in southern Africa to the complex organisational landscapes of the US and Canada.

She has worked diverse issues, large and small -- from sexual selection in flashy African birds, energetics and behaviour of raptors in North America and southern Africa, national biodiversity and climate change strategic planning, policy and research, and the status and trends of the world’s ecosystems and their ability to support human health, livelihoods and wellbeing.

Earlier, Phoebe founded and ran Namibia’s national biodiversity and climate change programmes, contributed to that country’s environmental observation system, to the global board and scenarios group of the Millennium Ecosystem Assessment, and she coordinated the scientific work of the Global Invasive Species Programme secretariat. She has produced three books, numerous booklets and book chapters, and a government policy, in addition to over 100 scientific papers, and has successfully raised funds to establish a national park in Namibia.

Phoebe was recently honorary president of BirdLife South Africa (2013-2016) and serves on the editorial boards of Ecography, Climate Change Responses and African Journal of Ecology, and recently, Biology Letters and Animal Conservation.  She has been honoured with a Fulbright Fellowship and a Society for Conservation Biology Distinguished Service Award (government category), the latter the same year as Sir David Attenborough (media category) and Prof Georgina Mace (academic category).
