The Four Cat Rainforest of Namdapha & the Myanmar Borders
Situated in the southeastern corner of Arunachal Pradesh bordering Assam and Myanmar, Changlang is a district of intense tropical biodiversity and military history. Lined by the rugged ridges of the Patkai range, the district links the dense, multi-layered rainforests of Namdapha with the historic remnants of the World War II China-Burma-India theater.
The visual identity of Changlang district is Patkai forest green and Stilwell Road terracotta. Defining the district is **Namdapha National Park** (a massive 1,985 square km biosphere reserve housing tigers, leopards, clouded leopards, and snow leopards), **Pangsau Pass** (the historic mountain pass connecting India with Myanmar), **Lake of No Return** (the mystery lake on the border), and **Stilwell Road** (the legendary Ledo Road built during WWII).
"Where the dense, moss-draped canopy of Namdapha shelters the elusive clouded leopard, the brick remnants of Stilwell Road run silently toward the Myanmar border."
