This anecdotal evidence suggests P. l. kimberleyensis may be able to respond to fire impacts by using sub optimal (but unburnt) habitat where forage resources may still be available.
There is increasing evidence across northern Australia that current fire regimes are resulting in; or have a synergistic impact on; the decline of a range of mammal species (e.g.
Drought combined with grazing impacts has reduced native grass cover and carrying capacity of rocky habitat for rock wallabies.
