This study sought to identify potential areas susceptible to defaunation, in the different biomes and regions of Brazil. Therefore, we assessed records of 13,573 AIA (Environmental Violation Reports) tilled by Ibama from 2012 to 2016. The results showed that 194,335 wild animals were seized, generating US$ 57,140,139.13in administrative fines. The captures occurred in 1,255 Brazilian municipalities, especially Caicó (RN), Recife (PE) and Cáceres (MT), with 27,677, 17,347 and 11,751 animals, respectively. The Northeast region had the highest amount in fines (US$ 28.9 million) and an annual average of 28,753 specimen apprehended, with a record above 100%, when compared to the annual average from 1992 to 2000, in a past study. The states of Minas Gerais, Rio Grande do Norte and Pernambuco had the highest absolute numbers. In the distribution by Class, birds, mammals and reptiles ranked 90.21%, 1.16% and 8.63% of the captures, respectively. As to the threatened species, there were 2,257 specimens, of which 70.05% were birds, most in the 'Vulnerable' threat ranking. We have concluded that the large illegal use of wild animals may lead to defaunation in some areas of Brazil, especially in the northeast region.
