Abstract

Brazil has the largest biodiversity in the world, with flora and fauna that encompass numerous species. However, due to several factors, mainly anthropic pressure, animal trafficking, burning and trampling, the number of animals is decreasing. Therefore, many animals that are victims of these factors need treatment, which is done through places authorized by the competent competent authorities, such as Wild Animal Screening Centers, to provide the service of sorting, treatment, rehabilitation and release or disposal of animals. Due to the shortage of information on the number of cases attended to wild animals in the extreme south of Brazil, the objective of this dissertation is to present, in the form of an article, the data collected of the receipt of animals that arrived for assistance at the Núcleo de Reabilitação da Fauna Silvestre, during the period of 2019 to 2021. After analyzing the data, it appears that a total of 5,255 animals were treated, with 1,026 animals in 2019, 2,013 animals in 2020 and 2,216 animals in 2021, noticing an increase of 79.33% of animals treated in 2021 compared to 2019. The class with the highest number of cases received were birds with 72% of receipts comparing to mammals and reptiles. The months with the highest reception of wild animals were November and December, apprehension (28%), followed by orphans (24%) were the main causes of these receipts and in 50.7% of cases, the animals were destined for release after the rehabilitation. The average length of stay of these animals in the institution was 38 days in 2019, 16 days in 2020 and 13 days in 2021. The awareness of this information makes possible to identify and create strategies that minimize impacts on wild animals in the extreme South of Brazil.
