There are an estimated 3,500 tigers left in the wild. Conservationists predict that If nothing is done wild tigers could be extinct within 10 years. But, they say, if action is taken the number could be doubled by 2022.
Tiger Tracks is presented by Save Wild Tigers, a global conservation awareness and fund-raising initiative.
Save Wild Tigers is working with two leading conservation charities, the Born Free Foundation and the Environmental Investigation Agency (EIA), to end the illegal trade in tiger parts and protect tigers in the wild.
While many of the events across Tiger Tracks will be free, visitors to the station will be encouraged to help tigers by donating funds to the Save Wild Tigers initiative with all profits going to the Born Free Foundation and the Environmental Investigation Agency (EIA) tiger conservation projects.
