156 Geoheritage Without Borders: International Perspectives on the Conservation and Celebration of Geodiversity, Part I

Every nation has a story to tell about its geodiversity–-but what are best practices to promote conservation of our geoheritage?  This GSA-ProGEO Western Hemisphere session explores innovative partnerships to conserve geoheritage and celebrate geodiversity.

Abstract

While the conservation of biodiversity is broadly understood and supported, the recognition and protection of geological diversity and geoheritage remains comparatively underrepresented. Geoheritage sites—areas with significant geological features of scientific, educational, cultural, or aesthetic value—play a critical role in fostering public understanding of Earth systems and preserving these insights for future generations. Successful geoheritage conservation efforts depend heavily on proper recognition, community engagement, and public education.

At the state, national, and international levels, formal frameworks exist to identify, recognize, and manage geoheritage resources. State geological surveys have led efforts to establish designated geosites and geotrails, providing accessible educational resources that promote the geological significance. At the national level, the U.S. National Park Service (NPS) supports geoheritage conservation through interpretive programs and by incorporating geological themes into broader resource management plans. Additionally, the NPS National Heritage Area (NHA) Program recognizes landscapes where natural, cultural, and historical resources form nationally significant narratives—many of which include key geological elements.

Internationally, the UNESCO Global Geoparks program offers the most comprehensive framework for recognizing and managing geoheritage sites of international importance. Global Geoparks are defined by their geological significance and managed through integrated approaches that balance conservation, education, and sustainable development. In contrast to World Heritage Sites, which offer strict protection for sites of outstanding universal value, or Biosphere Reserves, which emphasize biodiversity and sustainability, Global Geoparks focus specifically on geology and its relationship to local communities. There are currently 229 UNESCO Global Geoparks across 50 countries, including five in Canada and two in Mexico. The United States, however, has not designated any Global Geoparks, as it is not yet a formal participant in the program. A growing movement is advocating for U.S. involvement.

The U.S. Geoheritage and Geoparks Advisory Group, coordinated by the Geological Society of America (GSA), serves as a key resource in this effort. Drawing on over 15 years of collaboration with State geological surveys, the National Park Service, and UNESCO, the Advisory Group offers expert guidance to communities and organizations seeking to recognize and protect geoheritage through appropriate frameworks.

This presentation will explore existing approaches to geoheritage recognition, highlight case studies, and outline potential pathways for expanding geoheritage conservation across the United States.
