Friends of Ku-ring-gai Environment (FOKE) is a community group dedicated to protecting and conserving the built and natural environment of the Local Government Area of Ku-ring-gai. In 2018 it initiated the Ku-ring-gai GeoRegion project with the object of making a positive contribution to conservation based in around the Ku-ring-gai Chase National Park.
The proposed GeoRegion now embraces the Ku-ring-gai Chase National Park, other bushland areas, as well as the coast and estuaries located just north of the city of Sydney.
The Linnaean Society has published the review paper The Natural and Cultural History of the Ku-ring-gai GeoRegion, New South Wales
