Cave and Karst Outlook
The Environmental Caves and Karst Outlook (ECKO) aims to collect basic information on the current status of caves and karst, focusing on geological diversity, protection measures, biodiversity conservation, and the impact of human activities. It includes links to speleological federations and research.
The International Union of Speleology started this campaign in 2025 and askes its members to list the main issues in just 3 pages per country.
Help us to collect cave and karst information:
We will soon update this section with the questionaire.

The General Assembly Meeting of the International Union of Speleology (UIS) voted 2022 to work on a report on the status of caves and karst and that UIS member countries will provide data.
In 2024 the Speleological Federation of France did the first Environmental Outlook Status of Caves in France. It became the role model for the European Environmental Caves Outlook EECO form of the European Cave Protection Commission and later for the UIS.
At the International Congress of Speleology 2025 in Brazil the UIS presented the Environmental Caves and Karst Outook to its members. The UIS Karst and Cave Protection Commission KCPC established a ECKO working group.
