  • Our planet's astonishing biodiversity is vanishing at a rate 1000 times faster than at any time in history. The populations of many of our most charismatic species, such as the black rhino and Amur tiger, are teetering on the edge. But to halt this catastrophe in its tracks and to protect these species more effectively, we need to know where they are and how many are left. Even for well-known species such as cheetah, there are country-sized gaps in our knowledge. Many methods of surveying species are expensive, invasive or potentially harmful to the animals. But a solution might be right under our feet: footprints. A footprint is a small and often cryptic repository of valuable data about the animal that made it.
