Natural and Scientific Interests

The Crowe Bridge is a very special and unique area along the Crowe River with natural heritage features that has been studied and documented.
The research done by the community in the last year has uncovered some official documents and publications where the Crowe Bridge has been mentioned, listed and studied.

There are areas of land and water containing natural landscapes or features that have been identified as having life science or earth science values that are twice listed in the Natural Heritage Information Center at the Minister of Natural Resources.

The Natural Heritage Information Centre (NHIC) compiles, maintains and distributes information on natural species, plant communities and spaces of conservation concern in Ontario. This information is stored in a spatial database used for tracking this information. The Centre also has a library with conservation-related literature, reports, books, and maps, which are accessible for conservation applications, land use planning, and natural resource management.

A Natural History Show

Graham Wilson, a local geologist has made several field trips to the area to study and document the Crowe Bridge. Graham has generously volunteered his time and expertise to help 'Save the Crowe'

He has put together a 'Natural History Show' of his work for everyone to view and enjoy.
