UNESCO Global Geopark status is only ever awarded for a four-year period at a time. The ERUGGp Revalidation in 2023 was successful, and a Green Card was awarded to the English Riviera ensuring that the area, provided it continues to adhere to the UNESCO International Geoscience and Geoparks Programme Statutes and Guidelines, retains the status for the next four-year period.
UNESCO Global Geopark designation is not just about rocks, it is something to be proud of; it is about people, place, heritage, activity, creativity, engagement and involvement.
Audrey Azoulay, UNESCO Director-General, said: "At a time when we all look for solutions to build more resilient societies after Covid-19, UNESCO sites offer a wealth of concrete actions to reinvent our relationship with nature, to develop decent jobs and foster social cohesion. This report by the UK National Commission to UNESCO is a blueprint for sustainability, and I believe all Countries can take inspiration from this research."
All UNESCO Global Geoparks around the world celebrate their internationally significant geology and interrelated environment, heritage and culture. In Torbay, the geology at the heart of the designation covers four time periods, the Devonian, Carboniferous, Permian and Quaternary with discoveries being of such importance that they lead to the naming of the Devonian Period itself, changed the understanding of the antiquity of man and today are recognised through one of the highest concentrations of protected geological sites in the UK. Such a rich geological heritage and the sheltered aspect and subsequent micro-climate it created, has provided perfect habitats for specialist plants to thrive on the thin limestone soils, rare birds to find homes on the cliff ledges and farmland fringes, endangered bats to roost in the caves, whilst underwater sea horses shelter amongst sea grass. Geology has also shaped our human history with the natural harbour at Brixham developing into the second largest fishing port in the country and the rich soils providing the ideal farming conditions for the early inhabitants of Torre Abbey and Cockington. What was once attractive to the cavemen of Kents Cavern is still attractive to the residents and visitors of today.
The grey limestone rocks of the Bay, easily seen at Hopes Nose and Berry Head, were formed in warm tropical seas south of the equator. Corals and sponges abounded, building highly biodiverse reef-system. Meanwhile volcanoes blasted away, periodically blanketing the sea floor with ash and debris.
Huge tectonic forces moved the Devonian sediments northwards, and they were squashed, folded and faulted when two continents collided, and a giant mountain range formed as a result.
The mountains began to erode away in the middle of a some of the hottest deserts ever known, leaving the ancient limestone and other rocks exposed at the surface. All the red rocks of the bay were formed in this desert, at a similar latitude to the Sahara today. Meanwhile giant 1.5m millipedes scurried around the wadis where the mountains met desert plains.
Although having arrived at the same latitude as today, the region saw dramatic oscillations from warm Mediterranean-style climates to bitterly, cold Ice ages. During glacial conditions the English Channel was waterless and the local caves records show that giant extinct animals such as mammoths and lions inhabited these landscapes, along with some the earliest traces of people in Britain.
