The IUCN’s World Heritage Outlook Report for 2025 has been released, and India’s Khangchendzonga National Park, a UNESCO World Heritage Site, has been rated as the best-managed site in the country under the “good” category. The park lies in Sikkim, a Himalayan state in the northeast, and is home to Mount Khangchendzonga, India’s second-highest peak after K2.
Great Himalayan National Park, Nanda Devi and Valley of Flowers National Park, Kaziranga National Park and Keoladeo Ghana National Park have all been placed in the “good with some concerns” category. Manas, the Western Ghats, and the Sundarbans (shared by India and Bangladesh) fall under the “significant concern” category. All other sites are listed as “data deficient.”
UNESCO World Heritage Sites receive the highest level of international recognition under the 1972 World Heritage Convention. These sites are considered to have outstanding universal value, and their protection goes beyond national borders, cultures and generations. Natural World Heritage Sites also act as a key measure of how well the global community is protecting nature as it works toward the Kunming–Montreal Global Biodiversity Framework (KM-GBF) targets for 2030.
After the 2025 meeting of the World Heritage Committee, the World Heritage List now includes 1,248 sites. Out of these, 276 are recognised for their natural values (235 natural sites and 41 mixed sites). Although they make up only 8% of the total area of protected land and sea recorded in the World Database on Protected Areas (WDPA), they include some of the most important natural places on the planet.
The IUCN World Heritage Outlook 4 builds on four cycles of Conservation Outlook Assessments conducted since 2014. It presents the 2025 results along with long-term trends drawn from all four data sets. The report acts as an indicator of how effectively protected and conserved areas are being managed at a time when the world is tracking progress toward global biodiversity and climate goals, especially those under the KM-GBF.
Outlook assesses the conservation prospects of all natural World Heritage Sites by looking at the values for which they were listed, the threats they face, and how well they are protected and managed. These sites represent some of the planet’s most important natural areas, and their conservation must meet the high standards set by the World Heritage Convention. Their condition is also a test of how successful global conservation efforts are as a whole. Ensuring a positive outlook for these sites is therefore a priority, as highlighted in the Promise of Sydney adopted at the IUCN World Parks Congress in 2014.
The report also identifies current and potential threats to natural World Heritage Sites. Current threats include activities already affecting the site’s key values, such as construction, invasive species, tourism pressure or natural disasters. Potential threats refer to planned activities or emerging trends that could cause damage in the future if they occur. Each threat is rated in one of four categories: very low, low, high or very high.
Khangchendzonga National Park
Khangchendzonga National Park (KNP) forms part of the larger Khangchendzonga Biosphere Reserve (KBR). Together, the KNP/KBR landscape covers almost 40% of Sikkim and lies mainly in the North and West districts. The entire area sits along the Sikkim–Nepal border and stretches from the South Lhonak Glacier in the trans-Himalayan region down to the Barsey Rhododendron Sanctuary in South Sikkim.
It is a trekker’s paradise, with habitats ranging from lowland subtropical forests to high alpine meadows, glaciers, and snow-covered peaks. The park includes Mt. Khangchendzonga (8,598 m), the world’s third highest and India’s second highest peak, making it the highest-altitude wildlife protected area in the country.
Most of the core zone remains permanently under snow, dotted with numerous towering peaks. The surrounding buffer areas and inhabited fringes hold the richest wildlife habitats. This vast and dramatic wilderness has snowy mountains rising over pristine forests that are still largely undisturbed.
Diversity at Khangchendzonga National Park
KNP is rich in birdlife, with at least 127 species of conservation concern, including four globally threatened, three near-threatened, and three restricted-range species. The high-altitude lakes near Kishong La serve as important stopover sites for migratory waterfowl and are also breeding grounds for species like the Ruddy Shelduck.
Because of its vast size and wide range of elevations, this national park supports almost all the major wildlife species found in Sikkim. Only a few species found on the Tibetan plateau such as the Tibetan Wild Ass and some species found east of the Tista River like the Takin and Gaur are absent here.
About 19 mammal species listed under Schedule I of the Wildlife Protection Act, 1972 are recorded from this landscape. These include the Snow Leopard, Alpine Musk Deer, Brown Bear, Serow, Bharal, Himalayan Tahr and Tibetan Wolf. The region also supports important herpetofauna such as the Indian Rock Python, several freshwater amphibians, and a variety of beetles and butterflies that are legally protected.
There is also a possibility of small, undocumented populations of the Himalayan Newt in unexplored mid-altitude water bodies (1,300–1,900 m) across the Great Rangit River in the Darjeeling district.
Does Khangchendzonga National Park Support Tiger Safaris?
While Khangchendzonga National Park is home to extraordinary alpine biodiversity – including species like the Snow Leopard, Red Panda, Himalayan Black Bear, and Musk Deer – it does not support tiger safaris. Bengal Tigers are not naturally found in these high-elevation habitats of Sikkim. The rugged, cold terrain of Khangchendzonga is suited to high-altitude wildlife rather than tigers, which prefer the warmer forests and grasslands of India’s central and northern plains.
Travelers seeking tiger safaris in India are better rewarded in national parks such as Jim Corbett, Ranthambore, Bandhavgarh, Tadoba, and Kanha, where thriving tiger populations reside in their ideal natural ecosystems.
Conclusion
Khangchendzonga National Park stands out not only as India’s best-managed World Heritage Site but also as one of the most significant natural landscapes in the Himalayas. Its vast size, dramatic altitude range and largely undisturbed wilderness make it a stronghold for biodiversity. From the world’s third-highest peak to rich forests, alpine meadows, glaciers and high-altitude lakes, the park supports an exceptional variety of species, many of them globally threatened or legally protected. Its birdlife, rare mammals, unique reptiles, amphibians and even unexplored habitats reflect both the ecological richness and the scientific value of this region.
The IUCN World Heritage Outlook 2025 highlights the role of such natural World Heritage Sites as indicators of how well we are conserving the planet’s most important ecosystems. Khangchendzonga’s positive assessment shows the effectiveness of protection and management in Sikkim and reinforces the park’s global importance. Safeguarding this extraordinary landscape is not only crucial for India but also for the wider international community striving to meet global biodiversity goals.
