    Abstract

    We trapped and radio tracked quokkas, seasonally over a period of two years (2013 to 2015), in four key habitat types on Rottnest Island: coastal dunes, grass/ heath, woodland, and the settlement areas that are highly developed for tourism. We tested for the effects of factors such as season, rainfall and habitat type on the home ranges, body condition, reproduction, density and population dynamics of this important subpopulation. In the high density settlement areas, increased resources have improved body condition, joey survival rates and advanced breeding times, while movement patterns have been altered. Outside of the settlement, seasonal resource availability most greatly influences the ecology of the quokka, with the arid summer season negatively impacting on body condition, reproduction and survival.
