A hybrid consultative meeting was held at the Ministry of Environmental Protection of Turkmenistan to discuss the nomination dossier for the transboundary natural site "Karsts, Canyons, and Caves of Koytendag" for inclusion in the UNESCO World Heritage List. The meeting brought together representatives from the Michael Succow Foundation for Nature Conservation, Conservation X Labs, the Slovak Speleological Society, Humboldt University of Berlin, the National Committee for Ecology and Environmental Protection of Uzbekistan, the Institute of Zoology of the Academy of Sciences of Uzbekistan, the Secretariat of the National Commission of Turkmenistan for UNESCO, as well as the National Institute of Deserts, Flora, and Fauna of the Ministry of Environmental Protection of Turkmenistan. Participants reviewed the implementation of the "Road Map" for the site and discussed the results of joint field surveys conducted in the spring of 2026 at the Koytendag State Nature Reserve in Turkmenistan and the Surkhan State Nature Reserve in Uzbekistan. International experts compared photographs of dinosaur tracks found in Turkmenistan with similar sites globally and reviewed images of caves in both countries worthy of international recognition. Special attention was given to preparing the Preliminary Assessment application. This crucial stage involves defining the site's boundaries, identifying its core features and values, analyzing potential threats, addressing management issues, and outlining the procedure for agreeing upon and submitting documentation to the UNESCO World Heritage Committee. The joint Tentative List of Turkmenistan and Uzbekistan was submitted to the UNESCO World Heritage Committee in September 2025. According to the updated Operational Guidelines of the Convention, state parties must undergo the Preliminary Assessment phase before submitting the full nomination dossier. Upon receiving positive feedback from the International Union for Conservation of Nature (IUCN) experts, the parties will proceed to compile and submit the full nomination package. National experts, alongside international advisors from the Michael Succow Foundation and Uzbek specialists, will continue their collaborative work, taking into account the new requirements of the UNESCO Convention Concerning the Protection of the World Cultural and Natural Heritage.
