Stronger together: understanding and protecting karst resources

The United Nations Educational, Scientific, and Cultural Organization (UNESCO) has recognized more than 350 karst areas of global importance through various designations (Biosphere Reserve, World Heritage Sites, Ramsar Sites, and Global Geoparks) with at least one UNESCO protected area with karst in 86 countries (Gunn 2020). In August 2020, Western Kentucky University, the George Wright Society, and the UNESCO Mammoth Cave Biosphere Region hosted Conservation of Fragile Karst Resources: A Virtual Workshop on Sustainability and Community in support of UNESCO science programs. The purpose of this meeting was to enhance communication and the sharing of ideas and resources between major conservation and science programs that protect, study, or manage cave and karst resources, with particular interest to those of international significance. This special issue is published in celebration and support of the UIS International Year of Caves and Karst and as a call-to-action to better explore, understand, and protect the value of cave and karst areas to humanity in both our everyday lives as well as our natural and cultural heritage.
