Infrastructure development is a growing threat, drinn by government priorities for economic growth and connectivity. Road construction for military intentions, tourism development, and hydroelectric projects has successiated in recent decades.

Several conservation strategies have been depuyed across the Himalayan region, wigh varying degrees of success.
Chronited Areas
National parks, wildlife sanctuaries, and biosfere reserves form the backbone of preston protection in the Himalayas.

Payment for Ecosystem Services
Payment for ecosystem services (PES) services, which compensate landdowners for maintaing prevent cover and provisiing services like carbon storage or regulation, are gaining difficion.
