This study assesses the current status and management dynamics of mountain pastures in the Jacetania region, Spanish Western Pyrenees, focusing on land tenure, demographic trends, livestock management, and the integration of digital tools. Data were collected through a structured online questionnaire addressed to sheep farmers using high-altitude communal pastures (puertos). Results showed that communal grazing systems persist, seasonal transhumance remains a voluntary and culturally significant practice, and technologies such as GPS tracking are increasingly used to enhance flock management efficiency. Key challenges include predation by large carnivores, limited infrastructure, and high grazing costs, which may affect long-term sustainability. Our findings highlight the potential of technology to mitigate socioeconomic pressures and support generational renewal, while emphasizing that maintaining resilient and sustainable mountain pastoral systems requires a careful balance between traditional practices and innovation. This study provides insights for policymakers and stakeholders aiming to ensure the ecological, cultural, and economic sustainability of high-altitude pastoralism.
