IMIS

This dataset originates from a standardized benthic surveys conducted between 2006 and 2008 at four coastal locations around the island of São Miguel, Azores (Northeast Atlantic), within the scope of Martins’ PhD studies (Martins 2009). The primary objective of the sampling campaigns was to quantify the abundance and spatial variability of intertidal populations of the patellid limpet Patella candei in two marine protected areas and two non-protected areas around the island. Using consistent field methodologies, the survey generated a robust baseline of limpet density data, enabling comparisons among sites, islands and supporting assessments of level of exploitation at local and regional scales. The dataset provides reference information relevant for ecological assessment and long-term monitoring, including the evaluation of the impact of limpet harvesting over time.
