GPS tracking collars were fitted to five free-ranging dogs (Canis familiarise) in the Arcadia Valley, Queensland to establish baseline movement data in this unique topographical landscape. Activity areas were generated with three home range methods using seasonally constrained fixes. Activity areas (Brownian Bridge and Utilisation Distribution) ranged from 2.9 to 689 km² in this landscape, and revealed that topographical features previously thought to confine free-ranging dog movement were no barrier to habitat use.
