IGH 1 - Karst Theme
Karst is the name given to areas of limestone bedrock which have a high degree of weathering caused by solution together with a characteristic underground drainage system. The Burren is the best known classical karst landscape in Ireland, yet the majority of limestone throughout Ireland shows karstification. Even when hidden beneath a veneer of glacial deposits, karst features are found in many parts of the Irish landscape.

The Karst Theme panel looked at the full range of karst features and then identified the best sites for each of the features. It focused on finding areas of landscape which exhibited a diverse range of karstic features.
