DownsAbstractCape porcupines, Hystrix africaeaustralis, are one of the South African mammalian species that are increasing their distribution range and abundance with anthropogenic changing land-use. Knowledge of the home range of this species can provide important ecological information and explain their ability to persist in a range of land-use types. We investigated the home ranges of 15 radio-tagged Cape porcupines on farmlands, peri-urban and suburban areas in KwaZulu-Natal, South Africa. Using the 95% Kernel Density Estimate (KDE), Cape porcupines had an overall estimated mean home range of 39.37 ± 6.33 ha (n = 9) which ranged from 13.19 - 67.19 ha. When compared with other Hystrix species, Cape porcupines had the lowest estimated home range size. Individuals on farmlands had the smallest mean estimated home range area (24.57 ha), relative to peri-urban (34.61 ha) and suburban (45.18 ha) sites. Variation in the home range sizes of Cape porcupines with differing anthropogenic land-use type showed their behavioural flexibility in response to habitat homogeneity and forage availability in each. Our results suggest that Cape porcupine ranging ecology is influenced by food resource distribution and availability in various land-use types.
