Lorentz National Park was inscribed as a World Heritage Site during the 23rd session of the World Heritage Committee in Marrakesh, Morocco, on 29 November – 4 December, 1999. It is celebrated as being one of the most ecologically diverse national parks in the world, and a showcase of the biodiversity of New Guinea.
Lorentz National Park is home to 630 species of birds and 123 species of mammals. 70% of all the bird species in Papua can be found in this national park. They include two species of cassowary, 31 species of dove, 31 species of cockatoo, 13 species of kingfisher and 29 species of sunbird. Within Lorentz National Park are 26 species of birds endemic to the Central Papuan Ranges and three endemic to the South Papuan Lowlands.
There are different indigenous tribes living in Lorentz National Park. Among them include the Asmat, Amungme, Dani, Sempan and Nduga. Human habitation in the area goes back thousands of years.
Protection to the Lorentz area began as early as 1919, when the then Dutch colonial government established the Lorentz Nature Monument protecting 3,000 sq km of the area. In 1978, the Indonesian Government created the Strict Nature Reserve covering 21,500 sq km. Lorentz National Park was founded in 1997. It extends the coverage to the coastal areas and the outlying sea.
