The story of the Sumatran tiger is a very sad one. It is the beginning of the end of the road for this cat’s presence in the wild. There are between 100-400 left in the wild, worldwide, as at 10th June 2009 (note the wide range indicating uncertainty). And, as usual, the greatest threat to this cat’s existence is probably habitat loss (deforestation) and in this case it is carried out by one of the biggest logging companies in the world, based in Indonesia, Asia Pulp and Paper (APP).
This company, in league with the Indonesian government is probably responsible for the deaths of about 70% of all Sumatran tigers over the past 25 years. And the killing goes on unabated and nobody can stop it except the Indonesian government and there is no sign of that happening (see Deforestation in Indonesia (new window) – as at 10th June 2009).
Although the most important subjects are, in fact, deforestation and the tiger body parts trade, which makes it hard to talk about this tiger in a descriptive sense, I will try. Although, when this wildcat is all but extinct in the wild one asks, “what is the point”?”

Incidentally, an immediate negative consequence for both tiger and human is the increase in Sumatran tiger attacks as a result of dwindling forest: See Sumatran tiger attacks (new window). Both parties are forced together.
The cat’s scientific name is: Panthera tigris sumatrae. The outstanding appearance is its undoing as people like to possess something or a part of something this beautiful (or ingest it).
This wild cat was isolated from other tigers some 12 to 6,000 years ago because of rising sea levels. As a result it can be classified as a separate species. Historically it is regarded as a subspecies of the tiger. It is distinguished as a separate species or subspecies through morphological (biology which deals with the structure of animals) and genetic tests.
It is the smallest of the tigers averaging 136 kgs (males) and 91 kgs (females). By way of a comparison the Bengal tiger weights 222 kgs (males) and 140 kgs (females). They are good swimmers with webbed feet. The stripes are narrower than for the other tigers. All individual tiger patterns are unique. This is being used to track tigers (new window).
Unsurprisingly, the classification is Critically Endangered (CR):
Critically Endangered is explained:
“Organisms with a conservation status of critically endangered have an extremely high risk of becoming extinct in the wild in the immediate future.”
I have intimated the basis for this assessment in the introduction. The following is a summary of what the Red List says:
Between 1998-2002 51 tigers were killed in the following proportions:
|% Tigers killed in human/tiger conflict||15%|
|% tigers killed due to poaching for tiger body parts||76%|
However loss of tigers through logging (indirect killing it could be argued) is estimated at about 450 in the main area where APP operates, Riau province over the period 1982 – 2007 (src: WWF). This represents 70% of the tiger population of that area.
Tiger populations per reserve/area 2007 (src: Red List – new window) – note the wide range in the figures indicating to me that these are unreliable figures. Note these figures to the 2009 figures mentioned in the introduction:
|Bukit Barisan Selatan National Park (NP)|
|Batang Gadis NP|
|Kerinci Seblat NP|
|Gunung Leuser NP|
|Way Kambas NP|
|Bukit Tigapulu TCL|

These are mentioned above. Significantly the Red List does not list any conservation programs. And a search of the CITES website produced no record of a listing for this species. Is that correct? The Red List website does not say that it is listed in CITES either. This is very strange considering the open trade in body parts. Perhaps this species is considered a subspecies of tiger by CITES.
It is one way traffic downhill for the Sumatran tiger due to commercial exploitation of the tiger itself and the habitat it lives in. It is exclusively down to the Indonesian government to change things.
