For hundreds of years, the Koster population has worked within agriculture and cultivated the land and the forest into fields, meadows, forests and buildings. With its close proximity to Skagerrak, fishing and seamanship has also been a significant industry for hundreds of years. n fact, since the 17th century, Koster has been a sought-out area for lobster, which was later an exported product to Holland, Belgium, and other European countries.

In the mid-18th century, herring came to the coast in large quantities, and the herring fish industry became the most important industry in Koster for almost 200 years. However, at the beginning of the 20th century, shrimp fishing became popular, and it has since become the most important industry in Kosterhavet (Koster Sea). It is unclear when the first fishermen settled on the Koster Islands or when the islands were first permanently inhabited, but sources indicate that people lived on the Koster Islands during the 1300s.

There is evidence from the end of the 1300s about seven farms; Nordkoster, Långegärde, Upper Kile, Lower Kile, Röd, Brevik and Kyrkosund.


During this time, Koster belonged to the southeastern part of Norway and Koster was ruled by the Grimsø Monastery in Skien. Tax was paid in the form of agricultural products from Koster to the Grimsø Monastery.



There are only a few places in Scandinavia with such immense orchid meadows like the ones found on South Koster.

VISIT SCANDINAVIA


The location of the Koster Islands brings mild winters and sunny hot summers. “The sun shines bright above Koster” is an old expression that is certainly true. In addition to the welcoming climate, the soil is rich with limestone, resulting in biologically diverse flora. There is not a single place in Bohuslän with such large orchid meadows as those found on South Koster. The Koster Islands are home to several rare plants, and a considerable amount of these species are only found on Koster, making Koster one of Sweden’s most biologically diverse regions.

The Koster Islands have a rich wildlife. Most people are probably surprised when by the large seal population here. Large groups of seals are usually seen at the shores and islets southwest of South Koster. Deer, hares, and foxes are also found in large numbers on the Koster Islands. Seabirds, as well as migratory birds, are abundantly represented. They even use the Koster Islands as an “airport” as their first stop in Scandinavia on their journey from mainland Europe in the spring, or as their last stop in the fall before they cross Skagerrak and continue south again.

Kosterhavet Nationalpark

Kosterhavet National Park is a national park off the coast of Bohuslän in Sweden, and houses a unique ecosystem of 12,000 species (about half on land and half in the sea). Kosterhavet National Park was initiated in 2009, in an attempt to preserve and secure the vulnerable marine life in Kosterhavet (Koster Sea) and the unique nature of the Koster Islands. The national park includes 38,878 hectares around the Koster Islands, along Strömstad and Tanum municipalities in Västra Götaland county. The park also borders Ytre Hvaler National Park on the Norwegian side. The islands are separated from the mainland by the Koster Fjord, a 247-meter (810 feet) depression that connects to the Norwegian trench.
