### Conservation Quality of the SE Margin of the Ria de Arosa
#### 3.1.6 Conservation Quality Mapping of SE Margin of the Ria de Arosa  
This cartography aims to highlight areas within the territory where different strategies for their preservation and management are recommended (Figure 5). Within the entire region, certain areas stand out either due to the integration of multiple factors or because a specific factor is particularly prominent (Figure 6A-H). Arosa Island emerges as a site of high natural, landscape, and heritage importance. This area combines high landscape quality with geological and natural heritage features, especially along the southern margin. It is particularly important to highlight this area as a geological site of interest due to its geodiversity and its high scientific, educational, and touristic significance. Figure 5: Conservation quality mapping of study area. In the El Grove Peninsula, there are many zones with high landscape quality and natural heritage significance. The inselbergs located in the interior of the peninsula, including the Monte de Siradella viewpoint, are classified as geosites due to their representativeness of granite landforms in the area (Figure 6A). Additionally, the topographic prominence of the slopes and the naturalness provided by the dense arboreal vegetation further enhance its landscape quality, making it a priority site for the development of geoconservation policies and activities. The western sector of the peninsula, although it holds less geological interest, includes extensive areas belonging to the Natura 2000 Network wetlands. Furthermore, high landscape quality is observed, possibly influenced by the prominent granite domes and berrocal formations found in the area (Figure 6B). Compared to the interior zone, the

Other areas of high landscape quality, though less significant in terms of natural heritage, are associated with lithonstructral reliefs found in the interior of the Castrove Peninsula. In these areas, adequate management would be advisable to ensure the proper development of infrastructure. Most of the western coastal margin of the Castrove Peninsula features areas of interest for conservation measures (Figure 6D). Along the coastline, geosites have been identified that demonstrate geological processes, providing insights into the geological evolution of the coast. These include marine abrasion surfaces (terraces or marine platforms), dune systems, fossil beaches, and evidence of neotectonic processes related to coastline variation. Notable examples include La Lanzada Cape, Foxos Beach, Fagilda Cape, and Cabicastro Cape (Figure 6G). At these cages, the steep cliffs contribute to a high landscape quality, increasing their geological and scenic interest. Finally, the La Lanzada tombolo and the alluvial fan and cone systems located in the southern part of Unia-Grove Bay exhibit high natural heritage significance (Figure 6C,H). The scientific, educational, and touristic significance (particularly high in the Lanzada area) justifies their classification as geosites. Additionally, these zones include extensive areas that belong to protected intertidal systems. As a result, these areas are considered less of a priority for conservation since they already fall under the legal protection of the Natura 2000 Network (Figure 6E,F).
