SUMMARY:
The aim was to carry out a population census of cats in the Fernando de Noronha Environmental Protection Area (APA) and a population estimate encompassing both the APA and the Fernando de Noronha National Marine Park (PARNAMAR), Pernambuco, Brazil. This study aimed to perform a population census and estimate in Fernando de Noronha's Environmental Protection Area, Pernambuco State, Brazil. The census was accomplished during June, 2023, using the site visit method on all residences and commercial establishments from the 15 districts, through a survey application to tutors. In total, 879 cats were accounted for, being 32 domiciled (supervised by owners with movement restriction), 578 peridomiciled (supervised by owners without movement restriction) and 269 free-roaming cats were reported by citizens spotted in yards and nearby areas. The neutered cats percentage was 92.9% (567/610), which indicated that the population may stabilize in the next years; in relation to the animals' origin, the three districts with more cats reported were: Vila do Trinta (19.5%; 119/610), Floresta Nova (17.2%; 105/610), and Vila do Boldró (13.9%; 85/640); 540 cats (88.5%) did not have microchip; most of the cats (60.7%; n=370) had been neutered and ear-tipped for easier identification (T.N.R. method = trap-neuter-return); and there were eigth answers to how those cats got there, including: adoption (65.7%; n=401), born at home (10%; n=61) and abandonment (7.9%; n=48). The population estimate was carried out in May and June 2023 and sampling sessions were carried out on seven transects. The transects were located in six strata and their areas ranged from 0.71 to 4.01 km2. The estimated density of peridomiciled, free-living or feral cats sighted on the main island of Fernando de Noronha was 83.2 cats per km2 (95% CI = 61.5; 112.5). The population density in the strata varied widely from 20.6 to 193.1 per km2 and the population of these cats was estimated at 775 individuals (95% CI = 574; 1,048), ranging from 49 to 531 cats in each stratum. The current study represented the first domiciled, peridomiciled and free-roaming cats' census in this Conservation Unity, using both quantitative and qualitative methods. Finally, this census and estimate population will serve as a subsidy to public policy implementation regarding the population control of this important invasive species in Fernando de Noronha.
