Four cameras at Tibet's Mt. Qomolangma nature reserve will monitor key habitats 24 hours a day, said a senior reserve official on Saturday. The reserve has spent one million yuan (162,000 U.S. dollars) on technology to stop poaching, said Puqung, deputy head of the reserve in southwest China's Tibet Autonomous Region. Patrols and law enforcement in Mt. Qomolangma will also be stepped up to protect wild animals such as snow leopard, Tibetan wild ass and long-tail monkey. The Qomolangma nature reserve, created in 1988, was recognized in 1999 by the United Nations as one of the world's most successful examples of sustainable development. Covering 34,000 sq km, the reserve sits at an average altitude of 4,200 meters and is home to five of the world's 14 tallest peaks.
