A long term study in the Tost Mountains in the remote Southern Gobi desert of Mongolia, concluded that snow leopard are much bigger than what concluded earlier studies. As a conclusion, the study stresses on the importance of working with communities in non protected areas because very few protected areas would be larger enough to host viable breeding populations of snow leopards.
Here is a great article, which explains well the study findings compared to the publication:
‘Home range’ is a classic concept in biological research and is generally defined as the area that an animal utilizes in its daily life.
It’s a very intuitive idea, and it’s important if you want to describe how animals use space, both individually and in relation to each other.
This type of information is critical for conservation. For instance, in order to estimate how many snow leopards there may be in the wild, you need to have a good idea of the size of their habitat, and of how many cats can fit in that area
Different organization are working to secure 20 snow leopard landscapes by 2020:
