Cats and clouds: how a citizen camera-trapping project boosts wildcat (Felis silvestris) conservation

The European wildcat is an elusive small carnivore species whose distribution, behavioural ecology and interactions with domestic cats are scantly known. However, the use of camera-trapping is steadily increasing in wildlife studies as well as citizen science, with the latter setting the basis for a large source of robust data. Here we provide an overview of our efforts to create an independent network, named Piccoli Fototrappolatori Indipendenti (Little Independent Camera-trappers, hereafter PFI), of citizen scientists who are contributing with the goal of a deeper understanding of wildcat ecology. We engaged 31 volunteers who collected domestic cats, putative hybrids (hereafter hybrids) and wildcats' detections at 503 locations throughout Italy from 11/04/2006 to 24/10/2022. So far, this dataset hosts 312 images and 1015 videos (1327 detections) which were morphological examined and standardised, leading to 123, 137 and 1016 detections of domestic cats, hybrids and wildcats, respectively. We documented the expansion of the wildcat towards Northern Italy, with the first camera-trapping records from the Western Alps (Val D'Aosta) and from the Northern Apennines (Liguria), as well as the detection of kink-tailed wildcats in new regions. Moreover, we observed behavioural differences among cat types, with domestic cats marking at a lower rate and with hybrids being less elusive than wildcats at night. Further research and efforts are needed to better explore the conservation consequences of our findings, as well as to investigate the full potential of citizen science combined with camera trapping which are promising tools in wildcat conservation.
