Potential Geoheritage resources in Saudi Arabia for geotourism development: In the context of IUCN theme

Although geoheritage is gaining importance wordwide, much appreciation is still required for the overlooked geoheritage resources. The geoheritage of Saudi Arabia is promising and gaining much attention towards geoconversation and geotourism, but thematic publications are limited compared to the global context. This paper aims to identify the relevant geosites in Saudi Arabia according to the IUCN theme and propose a geoheritage strategic plan. For identification of the geosite published literature and online material, including web blogs, YouTube videos, social media, and governmental websites followed. For the strategic plan for known/unknown geosite, published literature from established geoparks with similar key landforms has been reviewed. Seven IUCN themes can be linked with the geoheritage of Saudi Arabia. Most of these sites are local tourist spots, therefore, immense potential for the geotourism development. The key geomorphological heritage in Saudi Arabia is volcanic harrat, escarpment, cave, mesas, butte, pinnacle, canyon, island, aeolian dune, and submarine corals. Geological heritage includes various fossils in Tuwaiq Mountain. Submarine geoheritage includes different colourful corals and rock structures with high scientific value. Biodiversity-protected areas and cultural heritage site enhances the geoheritage value of the geosite, and enhance the geotourism importance.
