sumatran/javan rhinos

sumatran/javan rhinos
22-06-2006

I thought I would start a new thread with regards to these two EXTREMELy endangered species. It's not really a zoo topic but relates quite well to a couple of other threads.

Pats comments on the sumatran rhinos are very relevant and interesting, especially with regards to my comments on the relevance of breeding emi, the sumatran rhino at cincinatti.

From what I have read there is very little hope for the sumatran in the wild. Most wild populations consist of, at most, 20 or so animals. The majority are smaller. They are isolated from each other and to make matters worse, the population on Borneo seem to be distinctly different from the rest that they could be regarded as a sub species.

Hunting and clearing of rainforest continues to endanger this species.

The Javans, though thepopulation is only at 80 or so animals could be said to be ina better positions. They are all together and fiercly protected.
However they may have been endangered by the tsunami in 2004. I haven't read anything about what effect that that had.

There was talk that the javan rhino national park (sorry can't remember its name) was full, not enough room for an expanding population. Someone suggested that an outlying ilsland provided plenty of suitable habitat and that a group of a dozen or so animals should be moved there. Any one heard about this? Is this a goer?

hmm. not sure jay. have heard conflicing info on this myself some say the javan national park is full - others say it has room to almost double the population. the good thing is that after many years of stagnation, the population has started breeding again in recent years.

i know of the two western/eastern subspecies of sumatran rhino. but didn't bother bringing it up earlier since it was just confusing things more. my beliefs are that they should keep the two poulations seperate....for now.
it may become evident in the future that lack of diversity especially in the bornean race which i believe is smaller will require a bit of cross-breeding. its a shame, but whatever saves the species. for now at least - all attempts should be to keep the two seperate and if the problem arises in the long term, well cross that bridge when we come to it.
a similar situation has arisen with the javan rhino's that where recently discovered in vietnam. with maybe only as few as 5 animals or less, one scientist ruled out introducing javans to vietnam (can you imagine how unlikely, difficult and controversial that would be anyway!) as the two subspecies where so distinct they couldn't interbreed.
personally, by that definition, that makes them different species and i can't see how just by looking at them one can declare them that!

nonetheless - i defibnately wouldn't advise sending javans to the wilds of land-mine infested veitnam. instead, since the population is so tiny and virtually unsalvageable id'e do intense tracking and population analysis to see if there are any reproductively viable animals, dart them draw blood, radio collars, DNA tests the works. if the have a couple of breeders then i say catch them and build a breeding center in the park. non-breeders - save their DNA......might come in handy down the track.

There was some take about moving some of the Javans out to another park in Java because they are running out of room for them in their current park.

sumatran rhino breeding centers....
22-06-2006

since the death of the seven rhinos at Sungai Dusun Sumatran Rhino Conservation Centre there are, i believe just two breeding centers left in the world. they are..

The Sumatran Rhino Sanctuary in Way kambas National Park, Sumatra houses four eastern sumatran rhino and hopefully soon a fifth with plans to move andalas there from the LA zoo. the other rhino are..

Torgamba, male arrived from Port Lympne Zoo, UK in 98.
Bina, female arrived from Taman Safari Indonesia, in 98.

and two recently arrived young females who were rescued after wandering into villages in 2005. they are..

Rosa, from the Bukit Barisan Selatan (BBS) National Park.
Ratu, from Way Kambas National Park.

andalas will be a great asset to the program.

also in malaysia at...

The Sepilok Orangutan Rehabilitation Centre, near Sandakan, Borneo
are two western sumatran rhino...

Tanjung, male, 15 years old
Gelugob, female, 25 years old

no luck breeding them as yet either.....

A real captive breeding attempt should have been made years ago with these two animal species instead of letting them full down to such small numbers as they are now, also there should of been a captive breeding attempt done with the Javan Tiger which as we know is now extinct, I dont recall any zoo any where even trying breeding these tigers, maybe some of you do know if someone had?. as i understand it they were still lingering around in low numbers in the 1970s.

Rhinos in national park
27-06-2006

There is a rhino breeding project within the Endau Ropin Conservation area in Malaysia , but off hand I cannot recall which species of rhino . But I do know that it is a fairly endangered species that they are concentrating on .
I have been to Malaysia , but not to Endau Ropin , mainly due to transport logistics issues .
As Malaysia is the closest neighbour to ( most of ) Indonesia , I wonder if there cannot be a combined multi national effort in the conservation issue ? There are certainly no land mines in Malaysia , and the geography of both countries are similar . There is certainly heaps of land inward from East Coast of Mainland Malaysia , not to mention in the Borneo states ......

Yeah Nigel, I know about the breeding centres for the Sumatran rhinos in Asia but what I meant was that this should of happened a good few years before they did get off the ground, maybe this would of given us a good headstart.
The Javan tiger was my case in point, a breeding program may of saved them.

27-06-2006

melbourne zoo once house javan tigers - as adelaide once housed a javan rhino....shame hey?

nigel, any info you can get on this "Endau Ropin Conservation area" would be great - i would edit my above text to give us a more precise list of where the sumatrans are (they will be sumatran here, there are no javans in captivity or in this area).

27-06-2006

Wow Javan Tigers, what year would that of been Pat, Do the records show they were imported from Java?.

27-06-2006

i haven't heard anything of the "endau ropin conservation area" but i can assure you that if it had a rhino captive breeding project - or even any rhino living wild in the area - then tehy where most definately sumatran rhino, since the javans are believed extinct throught their entire former range on the mainland and sumatra (except for those few in vietnam).

however, though it isn't proven, i find it unusual that sumatrans have managed to hold out in so many places (albeit scattered, fragmented and in tiny super endangered populations) and that javans have died out though all of eastern india, laos, burma, cambodia, thailand, malaysia and the indonesian island of sumatra. surely, if they can survive undetected in a tiny pocket of forest in land-mine and agent orange infested vietnam, then there must be a few still strolling around up in the jungled hills of laos or myannmar?

someones just gotta find em.... i nominate Zoo_Boy!

There have been a few reports over the years about Javan Rhinos roaming around in the jungles in parts of asia, parts of Thailand were one of them,I agree with you I would not be to surprised to find a few more lingering around somewhere in the back blocks of SE asia. In regards to the Sumatrans hanging on in parts of asia after the Javans having become extinct, from what I have been told the Sumatrans tend to in habit more hilly and mountain country (which had less people) where the Javans tend to inhabit more of the lowland country where they encounter many more humans (unluckly for them), In fact in the National park where they live on the western tip of Java thy have even been seen swimming in the sea.

28-06-2006

YAY!!!!!!!!!!!!!!!!!!! so whos gonna pay for my trip? but yea i totally agree, there has to be small pockets somewhere. also if the sumatrans are surrviving in small pop's does tht mean they would be inbreed somewhere along the line?

28-06-2006

yep, good one mark, that would make for a very logical explaination as to why sumatrans have fair better (though hardly by much!) than javans.

i am particuarly facinated by sumatran rhino - unlike javan's (who are essentially a small forest variety of indian rhino) sumatrans have all these unusual features - two horns, hairy coat, those skin folds so charictaristic of the asian species.

wild orangutans and (i'll settle for captive) sumatran rhinos are the next on my list of animals i have to see. i'm heading to borneo in december and i'll be sure to take lots of photos (to post here) of the rhino at sepilok

28-06-2006

Yes Pat I know where your coming from, my high-light of zoo going was meeting the two Sumatran rhinos at Port Lympne, to get to meet them alone (off exhibit) in their barn only with the head mammal keeper was unreal, patting them,sratching them behind their ears, having them muzzle me like huge dogs is just mind blowing stuff for me. I even got to give them some food. It got to a point with me that I was going to go to Sumatra to find them, at that time there were none captive anywhere, So in the end when i heard about these two at PL, I just had to go there.

Make time for the proboscis monkeys too, another Borneo rarity. Borneo is truly one of the last great wild paces left on the planet.
