About Geoheritage

What is Geoheritage?

The word geoheritage is derived from the term geological heritage, and is meant to refer to the abiotic, or non-living aspects of our natural environment that have significance, providing evidence of the processes and events in Earth history that have shaped our landscape, and which deserve our recognition and appreciation.

Digne Declaration: the Declaration of the Rights of the Memory of the Earth, was the first statement to recognize the value and importance of geological heritage and was signed by attendees at The First International Symposium on the Conservation of our Geological Heritage, held at Digne de la Baine, France in 1991.  The Declaration recognizes the uniqueness of Planet Earth, understanding that it represents the only bond that unites all humankind, and that its history cannot be separated from our own.

Geoheritage in Canada

Canada’s physical topology and landscape features are vast, varied and visually breathtaking.  It would not be surprising that the geological features and the processes that created them, and that support a multitude of environmental niches and ecosystems should be recognized and valued by Canadians.  We believe that they are.  They are just not universally called heritage in Canada. 

Canada’s heritage framework includes multiple national and provincial agencies that oversee various parts of the heritage portfolio, and while natural heritage is represented especially within Parks Canada, geology is rarely specifically designated within statements of Heritage Value.  In practice, this translates to a lack of awareness and few opportunities for education about the connection between Geoheritage and ourselves.  This is not a uniquely Canadian problem.  There exists a noteworthy gap in recognition of heritage sites of geological significance world-wide. In 2020, of the total 1121 sites on the United Nations World Heritage List, 213 are designated by natural heritage criteria, and only 98, or 11% by virtue of their geology (https://whc.unesco.org/en/list/).  Additionally, those that do exist do not represent the full breadth of geological periods, geological process or key localities illustrating the history of geology, including the geological time scale global references, known as GSSP (Global Boundary Stratotype Sections and Points) for geologic periods and faunal stages.   In short, there remains an imbalance in representation of the geodiversity on Earth.

The Friends of Canadian Geoheritage

The Friends of Canadian Geoheritage is a grassroots movement, begun by Dr. Alan J. Donaldson in 2003 and formed to address this problem; to promote recognition and preservation of Canada’s geological heritage.  It invited individual Canadians to engage with all levels of government to encourage the recognition, designation and preservation of Geoheritage Sites, sites of geological significance in Canada, which if destroyed would be lost forever.

Ottawa-Gatineau Geoheritage Project (OGGP)

A local offshoot to the Friends of Canadian Geoheritage movement, the Ottawa-Gatineau Geoheritage Project was born soon after. It now boasts many successes in recognizing, protecting and promoting the geological heritage of the National Capital region, including the rescue of biological features in Cambrian aged sandstones destined for destruction in highway expansion.  

The goals of the geoheritage project are: 

  1. PRESERVATION  of world-class geoheritage sites, by minimizing the loss of irreplaceable geological and surface landform features of the Ottawa-Gatineau region through insightful land-use planning
  2. PROTECTION  of geoheritage sites by strengthening and enforcing applicable laws to help preserve significant records of Earth history
  3. PROMOTION OF PUBLIC AWARENESS through the production of informative signs, brochures and guidebooks for geoheritage sites

These objectives involve the stewardship of local natural features and education of people living in the region. Provision of greater geoheritage recognition will add another dimension to the interesting heritage stories of the area for residents and tourists alike.
