A single forest corridor in Sumatra has yielded camera trap photos of five wild cats species, including the Critically Endangered Sumatran tiger (Panthera tigris sumatrae). Photos were also taken of the Sunda clouded leopard (Neofelis diardi), the marbled cat (Pardofelis marmorata), the Asian golden cat (Pardofelis temminckii), and the leopard cat (Prionailurus bengalensis). The five species were all filmed by a WWF camera trap survey in a single forest corridor linking the forest of Bukit Tigapuluh and the Rimbang Baling Wildlife Sanctuary in Riau Province. Unfortunately this forest remains unprotected.

“Much of the natural forest area in the landscape is threatened by large scale clearance for industrial logging, pulp and paper, as well as illegal encroachment for palm oil plantation development,” said Aditya Bayunanda WWF-Indonesia’s coordinator for the Global Forest Trade Network (GFTN) program in a press release. While a portion of the Bukit Tigapuluh is protected as a national park, forests surrounding the park, which have already been selectively logged, are now under threat of total clearance.

Sumatra has one of the highest deforestation levels in the world and has become a dramatic center in the fight to save rainforests. According to a detailed report released by WWF, the island of Sumatra—Indonesia’s largest—has lost half of its forest cover since 1985. Approximately, half a million hectares (larger than Rhode Island) of forest have been cleared annually, mostly for industrial palm oil and wood-paper plantations.

The five cat species documented in the forest corridor represent a wide-range of threat levels according to the IUCN Red List: the Sumatran tiger (Critically Endangered), the Sunda clouded leopard (Endangered), the marbled cat (Vulnerable), the Asian golden cat (Near Threatened), and the leopard cat (Least Concern).

“Four of these species [leaving out the leopard cat] are protected by Indonesian Government regulations – said Karmila Parakkasi,  of the WWF – This underscores the rich biodiversity of the Bukit Tigapuluh landscape and the forest corridors that connect to it. These amazing cat photos also remind us of how much we could lose as more of these fragile forests are lost.”

While five cat species in one forest is hugely notable, the largest number of cat species recorded in a single habitat is seven from a forest in India that recently gained protection.

Bayunanda says the presence of these cats should make the Indonesian government act to save the forest.

“Concession licenses of companies operating in these areas, such as Barito Pacific, should be reviewed and adjusted according to Indonesian Ministry regulations, which state that concession areas with the presence of endangered species should be protected by the concessionaire,” he says.

WWF-Indonesia also wants to see Bukit Tigapuluh National Park expanded. The Bukit Tigapuluh landscape is also home to Sumatran orangutans and Sumatran elephants amid thousands of other lesser-known species.
