An outstanding example of the biodiversity of New Guinea, Lorentz is one of the most ecologically diverse national parks in the world. It is the only nature reserve in the Asia-Pacific region to contain a full altitudinal array of ecosystems ranging through marine areas, mangroves, tidal and freshwater swamp forest, lowland and montane rainforest, alpine tundra, and equatorial glaciers.

At 4884 meters, Puncak Jaya (formerly Carstensz Pyramid) is the tallest mountain between the Himalayas and the Andes.

It contains five of World Wildlife Fund’s “Global 200” ecoregions: Southern New Guinea Lowland Forests; New Guinea Montane Forests; New Guinea Central Range Subalpine Grasslands; New Guinea Mangroves; and New Guinea Rivers and Streams.

Lorentz National Park has 630 documented species of bird (around 95% of the total number of bird species in Papua) and 123 mammalian species. The area of the national park has been inhabited for more than 25,000 years.

In 1999 Lorentz was declared a World Heritage Site by UNESCO.
