Jigme Dorji National Park: Bhutan's Himalayan park across five dzongkhags
Background
Jigme Dorji National Park (JDNP) was gazetted in 1974 as a wildlife sanctuary and upgraded to a national park in 1993.
Its revised area is 4,319 km2; until the Wangchuck Centennial Park was established, JDNP was the largest national park.
It covers five dzongkhags: Gasa (entirely), Paro, Punakha, Thimphu and Wangduephodrang, and 15 geogs.
Four major rivers originate in the park: Pachhu, Wangchhu, Pochhu and Mochhu, and major hydropower dams are built on them.
The park holds all four national symbols: blue poppy, takin, raven and cypress.
