A new study has provided a rare glimmer of hope for the Sumatran tiger, the last subspecies of tiger still in existence in Indonesia.
Reports that tiger populations are declining in many parts of its range paint a bleak and all too familiar picture. Of the 13 tiger-range countries recognised today, the Indonesian archipelago has already lost two distinct subspecies from the islands of Bali and Java.
Reliably determining where tigers are present within dense tropical jungle is challenging because their secretive behaviour and excellent camouflage naturally make them difficult to detect. But, for the past three years, eight NGOs have joined forces to carry out the first ever Sumatra-wide survey, in collaboration with the Indonesian Ministry of Forestry.
Hariyo Wibisono of the Wildlife Conservation Society (WCS) and chairman of the Sumatran Tiger Forum, who led the project, said: ‘This survey is a milestone for Sumatran tigers. The results provide the most up-to-date and reliable information ever collected for this critically endangered species.'
The comprehensive study found that while more than 70 per cent of forest patches surveyed were occupied by tigers, its status varied greatly between the different landscapes.
Speaking about the newly created 3.3 million hectare Leuser-Ulu Masen landscape in Aceh Province, co-author Dr Matthew Linkie from Fauna & Flora International explained: ‘This study puts Aceh's previously unsurveyed forest firmly on the map as a global priority for wild tigers in Asia.'

Blind Indus dolphin survey concludes in Sindh
The study was set in motion on April 16 by the Sindh Wildlife Department (SWD) in consultation with the World Wide Fund for Nature Pakistan (WWF P).
The SWD functionaries said that the survey team numbered 918 unsighted dolphins in the river Indus from Guddu to Sukkur.
The survey squad comprised 35 key officials of SWD and WWFP.
The officials recalled that that during survey carried on by WWF-P in 2006, around 810 dolphins were counted in the river Indus from the Guddu Barrage to Sukkur Barrage.
Assistant Conservator of SWD Ghulam Mohammad Guddani said : A distance of 200 kilometres from Guddu to Sukkur was covered for the survey and water samples were got after each 10 kilometers to determine causes of the death of 45 uncommon blind Indus dolphins covered from 2006 to 2011 March..
The final report of the water samples would be released publicly in three weeks, he added.
Guddani said that the survey is conducted every five years and formerly each survey has shown 40 per cent lift in the number of the dolphins. However, this survey has posted dissatisfied results.
No supporting growth in the dolphins population has been observed because of different reasons, he remarked.
Use of banned fishing net and poisonous chemicals by fishermen, unhampered release of hot poisonous water of the Guddu Tharmal power into the river Indus, release of drainage water and industrial wastewater into the river at Sukkur and the construction of hydel powerhouse along the Indus are among others, grave threats to the survival of the rare species, spelled out the SWD and WWF P officials.
The SWDs assistant conservator said, Data collected during the survey would be shared with the high officials of the wildlife department and other concerned departments..
He also said that he would suggest in the survey a request to the government to declare the River Indus area between Guddu and Sukkur a protected area for the sake of rare blind Indus dolphins sustainable survival and ban the use of fishnet and poisons chemical for fishing.
