Atropelamento de fauna silvestre em um trecho da PI - 411 no município de Corrente-PI

Abstract

Wildlife roadkill is one of the main environmental impacts associated with road infrastructure, especially in areas with intense human interference and habitat fragmentation. This study aimed to analyze the occurrence of wildlife roadkill along a section of highway PI-411, located in the municipality of Corrente, southern Piauí State, Brazil, identifying critical points and the environmental and anthropogenic factors involved. The study area comprised approximately 20 km between the urban area of Corrente and the rural community of Vereda. Data collection was carried out through weekly monitoring, with georeferenced photographic records of road-killed animals. Spatial analysis was performed using heat maps, combined with rainfall data from the sampling period. The results revealed a higher concentration of roadkill events at the beginning and end of the highway section, areas characterized by greater anthropogenic influence.. The findings indicate that wildlife roadkill along PI-411 is not randomly distributed, being strongly associated with human activities, water availability, and climatic seasonality. These results highlight the importance of targeted mitigation measures in the identified critical areas to reduce impacts on local biodiversity
