Registros de atropelamentos de fauna silvestre durante a 30a edição do Projeto Caminhada Ecológica

Abstract

The expansion of the Brazilian road network has caused significant impacts on biodiversity, with wildlife roadkill being one of the main causes of mortality among wild animals. The analysis of records collected during the 30th edition of the Caminhada Ecológica Project (an environmental awareness event held annually in Goiás, Brazil), conducted between the municipalities of Trindade and Aruanã, in the state of Goiás, enabled the quantification and characterization of roadkill occurrences along approximately 320 km of highways. The methodology was based on direct observation of carcasses, photographic documentation, and collection of information regarding location, time, taxonomic identification, and surrounding landscape. A total of 183 roadkill cases were recorded, involving 61 species, with mammals being the most affected group, followed by birds and reptiles. The species Cerdocyon thous and Myrmecophaga tridactyla were among the most impacted. Although no statistically significant differences were found between the road sections analyzed, spatial patterns suggest a higher incidence of roadkill in less urbanized areas with greater habitat connectivity. The study also identified endangered species, such as the giant anteater and the giant armadillo, highlighting the urgent need for mitigation measures. These results reinforce the importance of regional studies to support the development of public policies aimed at wildlife conservation. The implementation of wildlife crossings, guiding fences, and appropriate signage, along with continuous monitoring, is essential to reduce the negative effects of roads on wildlife.
