In November 2011, the WWF has announced 5 endangered cats in the forests of Riau. Within 3 months of systematic survey using automatic surveillance cameras at the 'corridor' between the Bukit Tigapuluh National Park and Rimbang Baling Sanctuary, they found Sumatran tiger (Panthera tigris sumatrae), Sunda clouded leopard (Neofelis diardi), marbled cat (Pardofelis marmoata), golden cat (Catopurna temmincki, and leopard cat (Prionailurus bengalensis). The cats passing the same tracks all the time in the corridor, but both areas connected by corridor are currently threatened by deforestation.
