Doctor Christopher Gordon

Chris GordonI’m a landscape ecologist and conservation biologist interested in understanding how biotic interactions and abiotic disturbances impact ecosystem dynamics and processes, with a key focus on developing tools for environmental and ecosystem management. I have a particular interest in wildfire ecology / risk management and trophic ecology and have extensive experience in these areas. My research on wildfire ecology / risk management has focused on understanding how historical wildfire regimes and fire severity impacts fire fuel loads, carbon sequestration, floristic diversity and fauna-flora interactions. My research on trophic ecology has focused on understanding how ecosystem disturbance through species extinction (especially keystone apex predators and ecosystem engineers) impacts species-species interactions, biodiversity and ecosystem resilience. I have worked across a variety of arid, semi-arid, savanna and forested biomes both in Australia and South Africa and my research uses a range of methodologies and datasets including landscape scale field surveys, small scale experiments, remote sensing tools, historical information and spatial and statistical analyses.

My passion for ecology and environmental management started during my honors research and employment as a research assistant at the Desert Ecology Research Group (University of Sydney; 2007 – 2010), where I worked on various projects focusing on reptile and mammal ecology. My PhD research at the Hawkesbury Institute for the Environment (Western Sydney University; 2011 – 2015) was entrenched in trophic ecology, and specifically aimed to understand how the extirpation of Australia’s largest apex predator, the dingo (Canis dingo), impacts ecosystem structure, resilience and biodiversity. My postdoctoral research at the Centre for Environmental Risk Management of Bushfires (University of Wollongong; 2015 – 2018) investigated how historical wildfire regimes and fire severity impacts fire fuel loads, floristic diversity, carbon sequestration and fauna-flora interactions. My postdoctoral research at the Centre for Biodiversity in a Changing World (Aarhus University, Denmark; 2018 – 2020) focused on megafauna ecology and trophic rewilding, using a case study of African elephant (Loxodonta africana) reintroductions in South African savanna to test how / when trophic rewilding can be used as a conservation tool to promote biodiversity.

As a Research Fellow within the Hawkesbury Institute for the Environment, I will be using remote sensing products and statistical techniques to determine how drought impacts wildfire occurrence and activity in wet forest types (e.g. rainforests) of eastern Australia.
