Professor George Perry
BSc(Hons)/MSc (Canterbury), PhD (Melbourne), PGCAP (London)
I completed undergraduate and Masters studies in the Departments of Geography and Plant and Microbial Sciences at the University of Canterbury, before doing a PhD at the University of Melbourne. I worked in the Department of Geography at King's College London for four years before moving to the School of Environment.
Research | Current
I am interested in the dynamics of forest ecosystems at spatial scales from the population to the landscape and at temporal scales from decades to milennia. All of my research involves a strong field-based component supported by simulation and/or statistical modelling.
My current research is primarily focused on understanding the effects of humans on forest ecosystems. I am particularly interested in how anthropic changes to disturbance regimes, especially fire, have restructured ecosystems and the legacies and challenges this has left for modern ecosystems. I am also interested in how forest loss modifies and disrupts plant-animal mutualisms. I have developed high-resolution chronologies for prehistoric extinction events, including NZ's iconic moa, and, I have worked with graduate students on a variety of topics concerned with understanding how altered landscape structure influences habitat connectivity, seed dispersal and animal movement. I am a collaborator on two projects focused on developing socio-ecological simulation models to support decision-making for ecosystem services and conservation in multi-functional landscapes. In the past I have conducted research in ecosystems in SW Australia, Spain, and New Caledonia.
I have designed an Excel add-in for spatial point pattern analysis (including nearest-neighbour methods, refined nearest neighbour, Ripley's K, the neighbourhood density function, etc.) called SpPack. This software is currently being used by a number of researchers around the world and is described in a paper in Environmental Modelling & Software. This software is freely available on email request.
Teaching | Current
My teaching is focused in the broad areas of terrestrial ecology, environmental change and associated quantitative methods. My main contributions are in ENVSCI 101 (Environment, Science & Management), GEOG 261 (Climate, Hydrology & Biogeography), GEOG 334 (Environmental Change), ENVSCI 705 (Environmental data analysis) and ENVSCI 737 (Applied Terrestrial Ecology). I also contribute to two courses in the School of Biological Sciences: BIOSCI 396 (Terrestrial Ecology) and BIOSCI 734 (Terrestrial Plant Ecology).
