A beautiful Sumatran Tiger at the San Francisco Zoo.

"The Sumatran tiger (Panthera tigris sumatrae) is a rare tiger subspecies that inhabits the Indonesian island of Sumatra," according to Wikipedia. "It has been listed as critically endangered on the IUCN Red List in 2008 as the population was estimated at 441 to 679 individuals, with no subpopulation larger than 50 individuals and a declining trend.

"The Sumatran tiger is the only surviving member of the Sunda Islands group of tigers that included the now extinct Bali tiger and Javan tiger.

"Sequences from complete mitochondrial genes of 34 tigers support the hypothesis that Sumatran tigers are diagnostically distinct from mainland populations.

"Sumatran tigers persist in isolated populations across Sumatra. They occupy a wide array of habitats, ranging from sea level in the coastal lowland forest of Bukit Barisan Selatan National Park on the southeastern tip of Lampung Province to 10,500 ft in mountain forests of Gunung Leuser National Park in Aceh Province.

"They have been repeatedly photographed at 8,500 ft in a rugged region of northern Sumatra, and are present in 27 habitat patches larger than 97 square miles.

"In 1978, the Sumatran tiger population was estimated at 1,000 individuals, based on responses to a questionnaire survey.

"In 1985, a total of 26 protected areas across Sumatra containing approximately 800 tigers were identified.

"In 1992, it was estimated that 400–500 tigers lived in five national parks and two protected areas. At the time, the largest population was reported from the Gunung Leuser National Park as comprising 110 to 180 individuals.

"However, a more recent study shows that the Kerinci Seblat National Park in central Sumatra has the highest population of tigers on the island, estimated to be at 165–190 individuals.

"The park also was shown to have the highest tiger occupancy rate of the protected areas, with 83 percent of the park showing signs of tigers. In fact, there are more tigers in the Kerinci Seblat National Park than in all of Nepal, and more than in China, Laos, Cambodia and Vietnam combined."
