... is the story of how and why the AONB has evolved over time. It has been affected by the area's geology, its climate, wildlife and human occupation.
The Arnside and Silverdale AONB is underlain by vast deposits of Carboniferous Limestone, which were deposited in warm shallow tropical seas some 335 million years ago. During the Carboniferous period the terrain that would eventually form the British Isles lay around the equator. Over the intervening 300 plus million years since then, the limestone area has been moved around by plate tectonics ending up in more temperate latitudes where it now resides. (Over geological time the area will move further north still, crossing the arctic circle in another 50-100 million years). In all the travelling to its current home, the limestone rocks were folded and faulted by plate collisions and mountain building episodes.
The geology of the area has set the context for both the natural heritage of the area and its lifespan of human occupation and influence, with only the last Ice Age leaving any other indelible mark on this special landscape.
The flora of the area is particularly adapted to the special geological conditions. The pattern of settlement has been strongly influenced by the occurance of natural springs and the construction of wells.The landscape character has been wrought from the rock by both natural and man-made changes. The local economy developed and grew from the geological resources that could be exploited. Be it dry stone walls, lime kilns, quarries, farm houses, villages, railways or reedbeds - all have their roots in the limestone that is the foundation of the landscape.
