Birds and plants
The island is mostly known for its rich birdlife and flora. It has large colonies of common guillemot (about 7500 breeding pairs) and razorbill (4500 pairs). In spring, there is an extraordinary number of orchids, mostly elder-flowered orchid and early purple orchid. There are also several very rare plants for Sweden such as Adonis vernalis, Lactuca quercina (called Karlsösallat in Swedish), hart's-tongue fern and Corydalis gotlandica (the only endemic plant on Gotland).[1]
History
There is evidence that Stora Karlsö has been inhabited since the Stone Age. During the Middle Ages there was a marble quarry, which gave the material for many of Gotland's churches. The island is a nature reserve, and after Yellowstone National Park is the oldest established protected nature area in the world. From May to August there are tour boats from the village Klintehamn.[1]
The Stora Karlsö Lighthouse was built in 1887. A house for the lighthouse keeper was added in the 1930s, which resulted in the island getting its first permanent residents in modern times. Since 1974, the lighthouse is automated and there are no permanent residents on the island. The lighthouse and the surrounded buildings are now listed.[3]
