JDNP is the second largest national park in Bhutan with an area of 4,316 sq km. Located in the north western part of the country, the park also shares international border with the Tibetan Autonomous Region of China. JDNP is rich in biodiversity with a present record of 36 mammals, 328 birds, five reptiles, 300 medicinal plants, and 39 butterflies. 

It was in JDNP where tigers were first sighted above 4000 meters sharing habitat with snow leopards. Besides the rich floral and faunal diversity, the sources of four major rivers, Pachhu, Wangchhu, Phochhu and Mochhu lie in the park as well.
The park spans across 5 districts, namely Paro, Thimphu, Punakha, Wangduephodrang and Gasa. Park headquarters based in Damji, Gasa and its 4 range offices addresses common challenges faced by protected areas elsewhere, like human-wildlife conflicts, unsustainable collection/or use of forest resources, and illegal wildlife trade.
