Tracking and protecting Mongolia's snow leopard

Mongolia's temperature has risen by two degrees Celsius, and scientists in the landlocked country are warning it could heat up by another four degrees by 2080, unless urgent action is taken.

The number of snow leopards is in rapid decline in Mongolia as their natural habitat is encroached upon more and more.

Film-makers William Davies and Hereward Holland have joined a World Wildlife Fund expedition in the Altai-Sayan mountain range in the west of the country, to see what can be done to protect and conserve them.
