Marco Polo sheep (Ovis ammon) have a scattered distribution in the Karakorum Mountain Range and Hindu Kush. In Pakistan, they are mostly found in the Khunjerab National Park and adjoining areas. The sheep have an endangered status and their numbers have been rapidly decreasing in the last two decades.

WWF-P plans to improve the status of Marco Polo sheep through the implementation of the Khunjerab National Park management plan, reduction of grazing pressure in Karchanai Nalla, improvement of watch and ward mechanisms, updating the population statistics, and identification of additional sites where Marco Polo sheep occur.
