The Azores, Madeira, and the Canary Islands are the archipelagos that contribute the largest marine area to the European Union. They also constitute marine biodiversity hotspots, with communities unique in European waters. This underscores the importance for these regions of implementing activities and policies aimed at the conservation and management of the seabed. The actions planned under MIMAR are geared towards understanding and assessing the changes occurring in the most important or relevant habitats (Natura 2000 Network). New threats to human health and activities will be identified, resilient elements will be delineated for protection and conservation, and the necessary tools will be provided to mitigate the harmful effects of these changes. This project will fulfill the Strategic Plan for Biodiversity 2011-2020 and target 9 of the Aichi Targets of the Convention on Biological Diversity.
