Abstract: Although nearly 30 years have passed since the Chernobyl Nuclear Power Plant accident near the town of Pripyat, Ukraine, the status and health of mammal populations within the Chernobyl Exclusion Zone (CEZ) remain largely unknown, and are of substantial scientific and public interest. Information regarding the response of flora and fauna to chronic radiation exposure is important in helping us understand the ecological consequences of past (eg Chernobyl and Fukushima) and potential future nuclear accidents. We present the results of the first remote-camera scent-station survey conducted within the CEZ. We observed individuals of 14 mammalian species in total; for those species with sufficiently robust visitation rates to allow occupancy to be modeled (gray wolf [Canis lupus], raccoon dog [Nyctereutes procyonoides], Eurasian boar [Sus scrofa], and red fox [Vulpes vulpes]), we found no evidence to suggest that their distributions were suppressed in highly contaminated areas within the CEZ. These data support the results of other recent studies, and contrast with research suggesting that wildlife populations are depleted within the CEZ.
