Site locations
The evaluation took place in two parts over three properties in New South Wales, Australia. Part 1 was undertaken on two private properties in the Central Tablelands in November 2017. Part 2 occurred on public land in the Central West in June2018. We classified the rabbit populations at each of these locations as very high (>10 rabbits/Ha), high (>5 rabbits/Ha), medium (2-5 rabbits/Ha) and low (<2 rabbits/Ha) using standard white-light spotlight counts (Mitchell and Balogh 1996). For Part 1, one property was overgrazed, had little-to-no vegetation and a very high population of rabbits. The other property was a disused stock paddock that contained stands of blackberry (Rubus fruticosus species aggregate) on the gully lines and was overrun with serrated tussock (Nassella trichotoma ). This property had a low rabbit population. Rabbit warrens on these two properties had an average depth of 600-800mm and we surveyed five warrens at each property. For Part 2 the land was part of the national travelling stock route (authorised thoroughfare for the walking of domestic livestock from one location to another across Australia) and at the time of the survey consisted of open sandy country with stands of Old Man Saltbush (Atriplex nummularia ). The average rabbit warren depth was 1500-2500mm and the rabbit population was classified as very high. We surveyed a 6.11Ha portion of the area.
