The snow-capped mountains of northern Pakistan are home to some of the world’s most elusive species, from the iconic snow leopard to wolves, bears, and ibex. Protecting them is no easy task.

Yet, our team at the Snow Leopard Foundation (SLF) is finding new ways to “listen” to nature’s hidden signals, while also relying on local guardians who keep a watchful eye on the ground.
