his 1973 tour. Their population density has been recorded as fewer than two animals per . The Marco Polo sheep was included on the first list of protected species issued by the Afghanistan National Environmental Protection Agency in June 2009. Khunjerab National Park The Khunjerab National Park was established primarily as a means to protect the Marco Polo sheep (as well as snow leopards and bharal) living in the area. The borders of the park were mapped by Schaller in 1974, after a short field survey. The park was formally established on April 29, 1975 by Prime Minister of Pakistan Zulfikar Ali Bhutto, who said that "it must become a world famous park". Despite being listed as a category 2 national park, banning human activities including agriculture and hunting, the park was poorly managed, meaning that illegal hunting of the Marco Polo sheep continued. Because of this, the International Union for Conservation of Nature commissioned Norwegian biologist Per Wegge to do a wildlife survey of the park in 1988. Wegge found that there was no evidence of competition between the domestic sheep being illegally grazed and the wild Marco Polo sheep, and that most of the illegal hunting was not being done by local Wakhi residents, but by Pakistani military and civil officials. He therefore proposed that the park be reclassified, allowing grazing and commercial hunting, with the profits going to local residents. However, the government overlooked Wegge's suggestions, instead drawing up a new management plan, which both the IUCN and the World Wildlife Fund supported as a means to preserve the park and protect the wildlife. Wegge was critical of the government scheme, claiming that it was based on financial considerations, with the Pakistani government hoping to attract tourists to the area. The IUCN agreed with this, and has since distanced itself from the national park. To help protect the animals from poaching, the WWF has created the Khunjerab Village Organization, which relies on people living in the area to report poaching or endangered animal sightings. Pamir Peace Park In 2008, George Schaller launched a campaign to protect the Marco Polo sheep. After the Khunjerab National Park was established by Pakistan in 1975; and the Taxkorgan Nature Reserve similarly settled in China in 1984, Schaller noted that the parks were insufficient to protect the sheep, due to their seasonal migrations. Schaller, among others, then proposed an international reserve in
