Orang Utans (Pongo pygmaeus)
are amongst the largest primates, and they belong to the three
species of apes left in the world (the others being chimpanzee and
gorilla). They are the only primates that build a nest every day for
the night. They are almost exclusively living in trees, are solitary
animals that mature and breed slowly and they prefer undisturbed
tropical rainforest. And all this is a big problem, for the
rainforests in Sumatra and Borneo, the two locations where orang
utans are still found, dwindle at an alarming rate. Tropical timber
is still very much sought after, as is the land on which it grows -
for plantations, mostly palm oil, to feed an every greedier consumer
society. In the last few scattered pockets of forests left the orang
utan can hardly survive because there is not enough food available.
And they can't meet each other for mating, orang utans simply don't
travel through plantations for courtship. It seems that for this age
the death knoll has been sounded a long time ago, and on an
international level zoologists are not entirely convinced that the
orang utan will survive the next 50 years.
There is hope though, and in Sabah
concentrated efforts are being made to ensure the survival of this
specie of primate. After all, they are also a big tourism
attraction... orang utans have given Borneo, and Sabah in
particular, a unique global identity, more so than any other
wildlife.
The Sepilok Orang Utan Rehabilitation Centre
in
Sandakan draws over 70,000 visitors
a year, and in 2004 foreign tourists outnumbered for the first time
local visitors, and this by a whooping 10,000! This comes almost
exactly 20 years after the centre was officially opened to visitors
in 1983. But Sepilok is only a rehabilitation centre where orphaned
and pet orang utans are trained to live an independent life in their
natural habitat. It is too small to support sufficiently large
numbers of the apes for continuous survival, and it is not a zoo
either (something you should always remember when visiting
Sepilok!). There still must be vast tracks of forests available for
them to be released, and where they cannot be disturbed, and Sabah
has introduced several measures to slow logging (introduction of low
impact logging, sustainable forests management, phasing out of
logging and a total cap on logging where orang utans still can be
found in large numbers by end of 2007) and ultimately complete
conservation of logged over areas so that the forest and its
inhabitants can rehabilitate. The areas include Danum Valley, Maliau
Basin, the Yayasan Sabah Concession, Dermakot and the whole of Ulu
Segama Reserve, the Malua Forest Reserve and the Ulu Kalumpang
Forest Reserve. By the end of 2007 Sabah will have close to one
million hectares (or some 13% of its land mass) of totally protected
and untouchable forests, much of it over unbroken territories for
orang utans and all the other animals and plants, many unique and
endemic (presently Sabah has also 1.1 million hectares of palm oil
plantation, much of it on formerly natural orang utan habitat...).
This move towards orang utan conservation is a dramatic step forward
and in stark contrast to previous reports which only cast gloom on
the future of Borneo's flora & fauna. So maybe there is hope? Dr
Senthivel K S Nathan, the officer in charge of Sepilok from
1999-2004 and now in charge of the soon to open zoo in Sabah in Kg
Ma'ang, Penampang believes now that "even if one day in 50-100 years
orang utans should become extinct, Sabah will be the last place for
this to happen." Their survival is by no means secured, as Dr Sen
elaborates: "Globally, of course, it is still a big question mark,
especially when you see what is happening in our neighbouring
country", referring to reports of a highway project cutting through
Sumatra's forest reserves and orang utans being sold in many
Indonesian markets. "With all the measures being put in place I
would think that the worst is over, for those in Sabah at least. I
am very confident that 10 years from now, if not an increase, at
least we will have a stable population. The estimated 12,000-15,000
that we have is a good number biologically speaking. To maintain
this is very doable so long as what we do now continues for the next
20 years," says Dr Sen.
The five main hotspots for orang
utans in Sabah are (see also map below):
- Ulu Segama Malua and
adjacent areas to the east of the Kuamut River which surrounds
the Danum Valley Conservation Area. This area supports an
estimated 5,000 orang utan. Of special significance are the
Ulu Segama and Malua Commercial Forest Reserves.
|
- Kinabatangan North area
comprising Segaliud-Lokan, Derrmakot and Tangkulap Commercial
Forest Reserves which support an estimated 1,700 orang utants.
Dermakot Commercial Forest Reserve is the only natural forest
in Malaysia that was granted international recognition under
the Forest Steward Council principles and criteria for
extraction of tropical timber under "sustainable management".
|
- Tabin Wildlife Reserve
with an estimated orang utan population of 1,400. This is
Malaysia's largest wildlife reserve
|
- Lower Kinabatangan with
a thousand orang utan, albeit in small and far apart pockets
of forests such as the Kinabatangan Wildlife Sanctuary, and
small forest reserves such as Supu and Gomantong.
|
- Kulamba Wildlife Reserve
with around 500 orang utans.
