 The selection of nesting sites by sea turtles is influenced by upper shore environmental cues, such as coastal erosion rates and urban development. Almost half of worldwide sandy beaches suffer from erosion and are located in highly developed areas, leading to habitat loss for beach-dependent species like sea turtles. Understanding the nesting ecology of endangered species like loggerhead sea turtles is crucial for devising mitigation strategies for human activities and climate change impacts. Our study found that the occurrence of loggerhead nests in southeastern Brazil was negatively related to higher urbanization levels and extreme erosion, with only 6% of nests found on severely eroded beaches. Approximately 50% of nests were found on low urbanized beaches, highlighting the importance of nature-based solutions to recover beach dune systems and mitigate coastal erosion where loggerheads are avoiding nesting. Management planning of protected areas, including nest relocation and monitoring, should be a priority action to ensure the survival of sea turtle populations.
