Swiss Tectonic Arena Sardona - Switzerland

The Swiss Tectonic Arena Sardona in the north-eastern part of the country covers a mountainous area of 32,850 ha which features seven peaks that rise above 3,000 m. 

The area displays an exceptional example of mountain building through continental collision and features excellent geological sections through tectonic thrust, i.e. the process whereby older, deeper rocks are carried onto younger, shallower rocks. 

The site is distinguished by the clear three-dimensional exposure of the structures and processes that characterize this phenomenon and has been a key site for the geological sciences since the 18th century. The Glarus Alps are glaciated mountains rising dramatically above narrow river valleys and are the site of the largest post-glacial landslide in the Central Alpine region.

Surtsey - Iceland

Surtsey, a volcanic island approximately 32 km from the south coast of Iceland, is a new island formed by volcanic eruptions that took place from 1963 to 1967. 

It is all the more outstanding for having been protected since its birth, providing the world with a pristine natural laboratory. 

Free from human interference, Surtsey has been producing unique long-term information on the colonisation process of new land by plant and animal life. 

Since they began studying the island in 1964, scientists have observed the arrival of seeds carried by ocean currents, the appearance of moulds, bacteria and fungi, followed in 1965 by the first vascular plant, of which there were 10 species by the end of the first decade. 

By 2004, they numbered 60 together with 75 bryophytes, 71 lichens and 24 fungi. Eighty-nine species of birds have been recorded on Surtsey, 57 of which breed elsewhere in Iceland. 

The 141 ha island is also home to 335 species of invertebrates.

Stari Grad Plain - Croatia

Stari Grad Plain on the Adriatic island of Hvar is a cultural landscape that has remained practically intact since it was first colonized by Ionian Greeks from Paros in the 4th century BC. 

The original agricultural activity of this fertile plain, mainly centring on grapes and olives, has been maintained since Greek times to the present. 

The site is also a natural reserve. 

The landscape features ancient stone walls and trims, or small stone shelters, and bears testimony to the ancient geometrical system of land division used by the ancient Greeks, the chora which has remained virtually intact over 24 centuries.

Socotra Archipelago - Yemen

Socotra Archipelago, in the northwest Indian Ocean near the Gulf of Aden, is 250 km long and comprises four islands and two rocky islets which appear as a prolongation of the Horn of Africa. 

The site is of universal importance because of its biodiversity with rich and distinct flora and fauna: 37% of Socotra’s 825 plant species, 90% of its reptile species and 95% of its land snail species do not occur anywhere else in the world. 

The site also supports globally significant populations of land and sea birds (192 bird species, 44 of which breed on the islands while 85 are regular migrants), including a number of threatened species. 

The marine life of Socotra is also very diverse, with 253 species of reef-building corals, 730 species of coastal fish and 300 species of crab, lobster and shrimp.
