Assessing hunter-gatherer mobility in Australia's Western Desert using historic aerial imagery from the 1950s
Access to water, food, and other resources is a critical factor structuring hunter-gatherer mobility, but few landscape-level studies have examined how resource availability influences where foragers go and how long they remain at one place before moving on. Using a newly available set of aerial images from the Western Desert of Australia taken in 1953, we utilize a simple ideal-free distribution model to reconstruct forager mobility by the fire footprints they leave behind. We examine three predictors of forager mobility and population density as measured by the density and dispersion of recent fires: 1) water availability, 2) habitat diversity (access to two or more high-ranking ecological habitats), and 3) seral diversity (higher prior use by human hunters). If foragers are attracted to high quality patches, there are substantial implications for understanding the spatially heterogeneous nature of forager-landscape interactions as mediated through fire. This, in turn, has broad implications for understanding and interpreting land use and population movements from initial colonization of the continent to the present.
