Advances in technology, such as SCUBA diving and underwater video cameras, have enhanced the observation of marine species, enabling comprehensive data collection essential for species distribution modeling (SDM). SDMs are crucial for conservation, helping identify potential habitats and inform protective measures. The Ciés archipelago, a diverse and productive ecosystem in the Atlantic Islands National Park, is a key habitat for the common octopus (Octopus vulgaris). O.vulgaris is an important commercial species in this region and faces population declines despite conservation efforts. Utilizing data from the CEFAPARQUES project, this study aims to determine the habitat preferences of O. vulgaris, and successfully address critical knowledge gaps to ensure the long-term viability of the population in this ecologically significant region. By analyzing environmental and occurrence data, areas of high probability of occurrence were identified, especially on the Eastern coast of the archipelago. The findings can help inform better management strategies within the national park, contributing to the sustainable conservation of O. vulgaris.
