In 1909, Sweden became the first country in Europe to establish a system of protected areas of distinctive natural character when nine of these were opened following the Riksdag passing of a law on national parks that year. There are currently over 30 national parks in Sweden. Many of the northern parks are part of the Laponian area, one of Sweden's UNESCO World Heritage Sites due to its preserved natural landscape and habitat for the native reindeer-herding Sami people. The southernmost parks—Söderåsen National Park, Dalby Söderskog National Park and Stenshuvud National Park—are covered with broadleaf forest and together cover approximately 2,000 ha (4,942 acres). Fulufjället National Park is part of PAN Parks, a network founded by the World Wildlife Fund (WWF) to provide better long-term conservation and tourism management of European national parks.
