Anu and Lasya are two female snow leopards we have been tracking via GPS collars. Both cats recently had cubs, and for the first time ever, our field team was able to visit both den sites. This breakthrough in conservation was recorded on film, and we are thrilled to share it with you now!

Snow leopard cubs filmed in den for first time
July 2012. After a month of intensive searching, an international research team has located the den sites of two female snow leopards and captured astonishing videos of a young cub resting inside a den with its mother.
The research team has been tracking snow leopards in Mongolia’s South Gobi desert since 2008 using GPS radio collars. In May, two of the study’s females began to restrict their daily movements to smaller and smaller areas, which the team interpreted as a signal that both were preparing to give birth. Traveling through steep and rocky mountain outcroppings, the team followed VHF signals transmitted by the collars and finally located the dens on 21 June.
High up in steep canyons
Only six kilometres apart, both dens were high up in steep canyons.
