In the 1990’s English Nature (now Natural England) adopted a ‘Natural Areas’ approach to nature conservation, and in 1996 an English Nature report (1) assessed the geological importance of each of the Natural Areas. Using a range of criteria, including the number of geological Sites of Special Scientific Interest (SSSI), in the area, the geological importance of each one was described as being outstanding, considerable, notable or some.
With some alterations to the boundaries, the Natural Areas have now been replaced by National Character Areas (NCAs) which divide England into 159 distinct natural areas, 15 of which occur in the North Yorkshire Geodiversity Partnership Area. Each is defined by a unique combination of landscape, biodiversity, geodiversity and cultural and economic activity. Their boundaries follow natural lines in the landscape rather than administrative boundaries, making them a good decision making framework for the natural environment.
