Where is Namdapha, and how did it get protected?
Where exactly is Namdapha?

- Location: Changlang district, Arunachal Pradesh. It sits near Miao town, right against the Myanmar border.
- Size: 1,985 sq km in total. That is a 1,808 sq km core zone plus a 177 sq km buffer.
- Why size matters: it is one of India’s largest national parks. Big parks give wide-ranging animals like tigers enough room.
How did Namdapha become protected in steps?
Namdapha did not get full protection in one go. Each step added a stronger layer.
Q1. True or False: Namdapha totals 1,985 sq km, split into a 1,808 sq km core zone and a 177 sq km buffer.
Q2. True or False: Namdapha became a National Park and Tiger Reserve in 1972, the same year it became a Wildlife Sanctuary.
Remember this: Sanctuary in 1972. National Park and Tiger Reserve together in 1983. The 15th Project Tiger reserve dates from 1983.
How can one park hold four big cats?
Why do these four cats usually live apart?
Tiger, leopard, snow leopard and clouded leopard each need a different kind of home. They differ in the height, climate and forest they prefer. A snow leopard would not survive in a hot lowland jungle.
Here’s why Namdapha is different. Its land rises from 200 m to 4,571 m. That climb packs several climate zones into one park, like stacking different countries on top of each other.
What does each height band of the park look like?
- Lower down: dense evergreen forest, warm and wet. This is tiger and leopard country.
- Higher up: the forest opens into montane forest and grassland.
- Higher still: snow-covered peaks take over. This is snow leopard territory.
- A fifth cat: the marbled cat also lives here. That makes five wild cat species, a very high number for any protected area.
Q3. True or False: Namdapha’s wide elevation range is the main reason it can support four different big cat species.
Q4. True or False: A fifth cat, the marbled cat, also lives in Namdapha, giving it five wild cat species in total.
Why does a tropical rainforest grow this far north?
What makes Namdapha’s rainforest an outlier?
Most tropical rainforests grow much closer to the equator. Namdapha breaks that pattern.
- It holds the world’s northernmost lowland evergreen tropical rainforest.
- It sits at about 27°N latitude.
- It is part of the Eastern Himalaya biodiversity hotspot.
Where does the name “Namdapha” come from?
The name joins two Singpho words. “Nam” means water, and “dapha” means origin. Together they point to a river’s source.
- The river is the Noa Dihing, a tributary of the Brahmaputra.
- It starts at the Chaukan Pass on the India-Myanmar border.
- It then flows through the park from east to west.
- A darker history: in the Second World War, refugees fleeing Burma used the Chaukan Pass to escape. Many reportedly died on the harsh crossing.
What lives in Namdapha besides the cats?
- Over 1,000 plant species and about 1,400 animal species.
- The red panda and the western hoolock gibbon, India’s only ape.
- The critically endangered white-bellied heron and Chinese pangolin.
Q5. True or False: Namdapha holds the world’s northernmost lowland evergreen tropical rainforest, at 27°N latitude.
Q6. True or False: The Noa Dihing River flows directly out of the Brahmaputra and into Namdapha.
Who lives inside Namdapha, and why does that cause tension?
Who are the people living inside the park?
Namdapha is not an empty forest. A few tribal settlements, mainly of the Yobin (Lisu) community, sit inside its boundaries. They depend on its forests to earn a living.
Here’s where the tension comes from. Park officials worry about encroachment and hunting. Yobin residents point out that they have lived there for generations. Both sides have a real case.
Why is the Miao-Vijaynagar road a double-edged sword?
- The road is about 150 km long. It links two remote settlements through the park.
- It has helped forest staff patrol more easily.
- But easier access also raises fears of more encroachment.
What did Eco-Sensitive Zone status add in 2024?
In 2024, Namdapha was declared an Eco-Sensitive Zone. This adds a regulated buffer around the park. It limits building and industrial activity near its edges.
Q7. True or False: Namdapha was declared an Eco-Sensitive Zone in 2024, adding a regulated buffer around its boundary.
Why does Namdapha’s wildlife keep vanishing and coming back?
How did the tiger come back on camera?
- No tiger sighting was confirmed after 2015. People began calling Namdapha a tiger reserve “without” tigers.
- On 8 February 2023, camera traps near Deban caught an adult tiger.
- Another tiger appeared on camera on 6 August 2024.
What happened to Namdapha’s elephants?
- Elephants once migrated from Namdapha to Myanmar.
- From 1996, encroachment blocked that route. Elephants then vanished from the record for years.
- One was camera-trapped again in early 2025, after a 12-year gap.
The lesson: in terrain this remote, “not seen” does not mean “gone”.
What is the Namdapha flying squirrel?
It is a squirrel first described from specimens collected here. It is critically endangered. It has not been reliably recorded since 1981.
Q8. True or False: A tiger was confirmed at Namdapha by camera trap on 8 February 2023, ending an eight-year gap in confirmed sightings since 2015.
Think it through, before reading on. Researchers went eight years without confirming a tiger at Namdapha, then found one anyway in 2023. Why would a species survive unseen for that long?
Show the explanation
Namdapha’s land works against easy observation. It runs from 200 m to over 4,500 m, across dense forest, remote valleys and snowy slopes. Much of it is very hard to patrol. A tiger or an elephant can move there for years without crossing a camera or a ranger. So a gap in sightings shows how hard detection is. It does not prove the animal has died out.
What have exams asked about Namdapha and Arunachal Pradesh?
- UPSC CSP 2025 asked if Arunachal’s capital is named after a fort, and if the state has two National Parks. Both are true. Itanagar is named after the Ita Fort. The two parks are Namdapha and Mouling.
- UPSC CSP 2026 asked about the western hoolock gibbon, which also lives in Namdapha. The trap: gibbons are small and light, not heavy like gorillas.
Q9. True or False: Arunachal Pradesh’s capital, Itanagar, is named after a fort, and the state has two National Parks.
