Orangutan still very sick but now eating.

I went out to the Care Centre today to check on Zidane. While still in a pretty awful state he is improving. We have brought one of the Camp Buluh staff back to town to sit with him throughout the day. He offers Zidane food whenever he feels like it. Zidane is eating but he is reluctant to drink. However, the affection he shows for people is touching. He actually slid off his makeshift cot for a hug. Thank you Brigitta for your generous donation of $100 it is very much appreciated by all of us.

(Apologies if the photo is dark – I deliberately switched the flash off)

Elly, from the UK office, is visiting the field projects at the moment so she came to the Care Centre too.

Elly receiving an enthusiastic welcome.

There is a pair of binturongs (Arctictis binturong) also known as bearcats at the Centre at the moment.

They are very cool animals. It is a dream of mine to see one in the wild… as well as to Zidane back in the trees.

A Very Sick Orangutan

Two weeks ago we were all very shocked when Zidane (pronounced Gee – dan) was brought back from Camp Buluh in the Lamandau Wildlife Reserve to the Orangutan Care Centre & Quarantine. Not only did he have rampant diarrhoea, was emaciated, running a fever but, more worryingly, he had 16 air rifle pellets under his skin. We have never seen this before and therefore we knew we had to act immediately and sort out what had happened in Lamandau.

A very sick Zidane at the OCCQ

A Forestry Police patrol went out for three days to interview all the rubber-tappers working along the river. Yesterday, the Lamandau Camps Manager, Tigor organised a community meeting to which he brought along district Government representatives, the police and a doctor from the Health Department. We want everyone who lives or works inside the Reserve to take worming medicines to prevent more infections. However, as this is the holy month of Ramadan, when people are fasting, yesterday’s meeting was a socialisation exercise. Once Ramadan is over we will have another meeting when the doctor will distribute the medicine.

14 days on and Zidane’s condition is stable. For the first few days we did not think he would pull through. He was given two blood transfusions, from another orangutan at the Care Centre, was on a constant drip to keep his fluids up, and as far as his body would take it, was given worming and anti-dysentery medication. But every day that he manages to hold on gives us slightly more hope.

Having the individual feeding tyres for the orangutans will help us distribute their medicines more easily and will stop orangutans congregating on a feeding platform, therefore reducing the chance of infection – thank you very much to everyone who has donated so far. Please do consider donating so that we can implement this new feeding system throughout Lamandau.

New Tyre Feeding System.

Camp Buluh

We will also build another Guard Post on the western side of the Reserve, which will prevent access to the headwaters of the Buluh River.

Although I can’t promise Zidane will pull through, I will give our word that we will do everything possible to find out what happened and to prevent another orangutan suffering in the same way.

Thank you,

Stephen

Bringing the office to our orangutan release camps.

A huge thank you Anna M, Kit C and Wanda H for responding to our recent ask for donations towards the solar power sets and the new feeding system, that we are establishing in Lamandau at our orangutan relesase camps. Both projects are very important and still require your support so please do consider donating. In response to my post about my awful journey to choose a guard post site, Sheryl (thank's Sheryl for your offer of a donation as well) commented “Your day at work is always infinitely more interesting than my day at work”. Do you really think so? I can assure you we deal with just as many mundane, administrative issues as everyone else. The only difference is the physical environment.

A trip Uli, who is our office manager, and I made proves the point.

The Indonesian government has a health insurance scheme onto which we want to enrol all our staff. In order to do that the necessary paperwork has to be completed. Before the paperwork can be completed the staff have to, firstly, receive the papers – we are talking about eight different project sites - and then know what they have to do.

A lot of our field assistants are, putting it in completely western terms, “country folk”. That, of course, is why they are great for us: they know the trees; seasons; animal behaviour and everything else you could possibly want to know about the forest. However, the flip side is paperwork is completely alien to them.

Boths the above photos show Camp Buluh one of our release camps in Lamandau.

So Uli and I set off on a whistle stop tour around four of the five Lamandau release camps, (the idea being for her to explain the form and for me to get a day out of the office!). I am sure it would be a modern “Human Resources Department” worst nightmare. Four people could not remember their own birthdays, with two not even being able to hazard a guess at the year.  A lot of the Dayak’s only have one name. Therefore “Riti” was a typical example of what was written for the section “Mother’s maiden name”. Uli, whose full name is Iria Yuliasih Siregar and who came to us from an office job in Jakarta coped admirably with a situation that was way beyond anything she’d experience previously. And it wasn’t just cultural….

Outside the windows curious orangutans were looking in.

An interested audience!

At Camp Buluh, Omang actually swung onto the boardwalk to get a closer look at why so many people were talking so animatedly at once.

Curious Omang

And if I said there was an orangutan at Camp JL called Hercules my guess is you are not picturing a cuddly infant. You’d be right. Hercules is a strapping sub-adult male in the full flush of the testosterone rush which precedes the development of cheek pads.

If I am ever in a camp at feeding time, I always try to accompany the guys out to see the orangutans. Uli came along too. It was good to see Bobi and Dodon with their youngsters. It was less good to see Hercules barrelling towards us once feeding was over.

At a push Uli might agree with Sheryl in describing the day as “interesting”. The rest of us described it as “Phew!!! That was fun”. Which is amazing as all we were trying to do was fill in some forms.

Help Needed with Orangutan’s New Feeding Sites

Last week I asked for your help to buy a solar power set for Pondok Ambung, our research station, well I'd like to ask for it again.

In May I wrote about how we had changed the feeding system at Camp Siswoyo in the Lamandau Wildlife Reserve (Feeding Orangutans - A New Approach). Instead of using a feeding platform as is done at all the other release camps, at Siswoyo we have hung cut-up and inside-out car tyres from trees. The orangutans’ food is then dropped into these heavy-duty “buckets”; the one tyre per orangutan system reduces competition, allows us to give an extra large portion to hungry or pregnant orangutans, or those with infants and the tyres eliminate the risk of disease transfer from the orangutans walking across a dirty feeding platform.

In May, I said the system was not 100% perfect. We have tried tweaking it: some of the tyres have been lowered so the field assistants can get the food out quicker; and the tyres are now in more of a circular arrangement, rather than in a line, so the orangutans do not all congregate at the start. This week Tigor, the Lamandau Camps Manager and I reviewed the system. Our conclusion was that we should do it in the other five camps!

And that is why I am asking for your help.

We need an extra 80 tyres; for efficiency we will buy an angle grinder so we can cut up the tyres ourselves and a bore to make the drainage holes; we need steel cable to attach the tyres to the trees and step ladders. The total cost will be just over $500 (5 million Indonesian rupiah)

Thank you Mary H. for your donation of $15 on September 1st and Brigitta for your donation $20 on the 5th September- we really appreciate your support.

On a final note, I would encourage all of you to do as Sheryl suggested and sign the petition http://getactive.peta.org/campaign/anjelica_huston_video to end the use of great apes by the entertainment industry. In addition to the obvious welfare issues surrounding performing animals, I read recently “A survey conducted of visitors to Great Ape Trust and cited in Science magazine (March 14, 2008) showed that the appearance of apes in advertising and entertainment negatively influenced the general public’s perception of the conservation status of apes in the wild.”I hope you can help.

As always, I will update you as we progress and thank you in advance.

Stephen.

Add Power To Our Research

Pondok Ambung, our research station in Tanjung Puting National Park, has been mentioned quite a bit in my blog. In the late 80's, Pondok Ambung was established as a proboscis monkey research site but by the end of 90's it had been badly damaged by illegal loggers. The Orangutan Foundation's team of volunteers repaired the site in 2001 but it remained abandoned until 2005 when the Rufford Maurice Laing Foundation awarded us a grant for its complete renovation.

And this is what we did.

The station requires a new solar power set. Solar is the only source of power providing electricity for the station. A new solar set costs $600 and any donations towards this amount would be hugely appreciated. So far the running and maintenance of the station has been entirely funded by the Foundation or from fees received from researchers staying at Pondok Ambung.

Recently, Pondok Ambung was used as the base for the “Orang-utan ‘08” expedition from the University of Aberdeen, Scotland. A team of four undergraduates led by Graham Banes spent eight weeks in Tanjung Puting studying the effects of disturbance, particularly forest fires, on the distribution and density of orangutans. Encouraging scientific research in Tanjung Puting National Park creates the knock on effect of increasing support for its protection.

Here are some of the incredible species that have drawn researchers to Pondok Ambung so far.

And of course...Orangutans!

Thanks for your comments on my last post - I've just about recovered!

Identifying Individual Orangutans

Paula's question of how do we identify individual orangutans is a good one. In many ways, recognition is done as we do with people: it is the whole appearance which guides identity. As with chimpanzees, but unlike gorillas, orangutans have lots of individual differences. One of the features I find most useful is the "forehead bump" all orangutans have but whose shape and size varies. Other unique features are hair colour, hair patterns, body-size, moles and scars. Adult males (cheek-padders) are easy; they all have different facial patterns and pad shapes. You learn to tell adult females apart by their individual appearance. The group I find the hardest (and at times impossible) to identify are old juveniles – young adolescents; orangutans aged from around 5 - 10 all look very similar. You can not tell the sexes apart; they all still retain a youthful lightness to their skin and, quite frankly, appear identical! Only the Assistants who see them very frequently can tell them apart.

I hope the attached photos show what I am talking about:

Tata: She is a big female; eyes quite close together; dark hair crown.

Princess: She has a line running from her nose to under her right eye, otherwise she has a smooth face with a narrow, pointy forehead-bump. Her coat colour is dark.

Siswi: Obvious!

Tut: Tut is thin to the point of being gangly; she has a distinctive fringe and her face is very lined.

Uning: Obviously still a young adult; Uning retains the lightness around the eyes and mouth which is typical of young orangutans. Her eyes are also quite close together.

Badut: Compared with other adult males, Badut has a narrow face.

Kusasi: His cheek pads are incredibly ragged.

Masran: The join of his cheek-pads is very triangular and he has a notch on his left pad.

Tom: Like Siswi, when Tom is around you know it! However, the join between his cheek pads is distinctive. I describe it as “messy”. Compare it with the photo of Win and you’ll see what I mean.

Win: Has a very obvious crease running across his left cheek-pad.

Juvenile: Beat me! I can’t even tell if the orangutan in the photo is a boy or a girl :-)

Siswi - Another Camp Leakey Character

Last week Brigitta asked me to give her regards to Siswi.  Unfortunately, I have not managed to get out of the office (hence this week’s blog, which has been more about individual orangutan histories than actual news from the field!).  However, I thought I would tell all of you about her because, like Kusasi, she is one of Camp Leakey’s characters.  Most visitors to Camp meet her and she’s pretty noticeable.  

Siswi has a distinctive gait, a unique habit of lying on her back holding her feet and, if there is a male around, she’s almost guaranteed to put in a show. 

 

People may consider her “rotund” but that does not appear to diminish her sex-appeal; she frequently consorts (the name given to the temporary male – female pairings, when a female is in season) with Tom, whereas a few year’s ago, she was definitely Kusasi’s girl.  Indeed, without trying to keep going on about the film “Kusasi: From Orphan to King” there is a delightful scene where Siswi is rolling along in front of Kusasi as he walks through the forest.   

What made Siswi famous from the outset was that she was the first ever offspring of a rehabilitated orangutan at Camp Leakey.  Siswoyo was released by Biruté Galdikas in 1975.  On the 9^th of September 1978 she gave birth to Siswi, evidence that once-captive orangutans can return to the wild.  Because of this, the first release camp in the Lamandau Wildlife Reserve is called Camp Siswoyo.   

Attached is Siswoyo’s family tree.  My apologies that the text appears to have jumped inside the boxes; I am no-one’s idea of a graphic designer! You may need to click on the family tree to read it.

Monitoring released orangutans

I see a number of people have asked how we monitor the orangutans once they have been released into Lamandau. There is nothing technical involved: our field assistants follow the orangutans from sunrise to sunset (or as we say, "nest to nest") everyday for a week. If after that time it is clear the orangutan has adapted to life in the forest, they will then be followed occasionally like the other previously released orangutans. If after the first week, the assistants are concerned that the orangutan may not be adapting they will continue to follow he or she for a month. Common causes of concern are the orangutans not making their own nests but choosing to sleep on the feeding platform or making a bee-line for Camp and not exploring their new surroundings. Within the first week, we expect to see the orangutans making their own nest, trying wild food and travelling. Nearly all achieve this.

Most newly-released orangutans tend not to go too far in the first couple of days but then they start to travel further and further. Last December I told you about the release of Sawit and her adopted son Andi. They took off within their first week, probably because Sawit was being hassled by a sub-adult male. The Assistants could not follow her through the swamps to the west of Camp Rasak. However, on 22 April, back they came, still together.

Which brings me onto the last element of the post-release monitoring; the daily supplemental feedings. In Tanjung Puting, where orangutans were released from the early 1970s to the mid-90s, the rehabilitants are offered food once a day. In Lamandau food is provided twice a day. This serves three purposes: it keeps up the nutrition levels of the released orangutans; it decreases competition for scare food resources with wild orangutans, gibbons, hornbills, and other wildlife and finally it enables us to monitor the orangutans’ development. All individuals coming to the feeding stations are recorded; over the course of a year, at least half of all released orangutans are seen. The Assistants also note whether they are consorting with the opposite sex, pregnant or with an infant and their general health.

 

For example, Boni who was released at the same time as Sawit and Andi came into feeding 26 times during April, and then every day in May and June. Lady Di, whose picture I showed you in April, was around for 28 days in April, May and June but Hongky was there for just 9 days in April, 14 days in May and 25 days in June.

In answer to “Rick, El Paso, TEXAS” question about the availability of this data, I am afraid to say it is not available online. We produce quarterly reports, in Indonesian, covering this information but the reports are for the Forestry Department and our own internal use. However, Tigor who manages the Lamandau Camps is providing information about our release program to an Indonesian PhD student at Cambridge University in the UK. So hopefully it will be peer-reviewed and published.

Please keep asking questions and I’ll try to keep answering them! Many thanks.

More orangutans returned to the wild.

Wow Kusasi certainly proved popular! Thank you for all the positive comments and nice to hear from you again Brigitta. If people want to see the film "Kusasi from Orphan to King" I understand it can be bought on-line from PBS.

The other week I wrote that July was Pondok Ambung, our Tropical Forest Research Station’s, "month". Certainly, the research activities there dominated my time, but that does not mean everything else stopped. In fact, four more orangutans were released from the Orangutan Care Centre & Quarantine into the Lamandau Wildlife Reserve.

I now have a bit of time to tell you about them. Biruté Galdikas supervised the releases with Tigor, the Manager of the five release camps. On 28 July, the adult female Sasha was released along with her adopted daughter Monica. Though Monica was no longer an infant, it is always good to see these adoptions work; no matter how competent the staff at the Care Centre are, obviously a female orangutan is the best possible mother for youngster.

The second release on 4 August was a bit more traumatic. The orangutans, Ucok and Lori, were OK, but the people had some problems! The orangutans were moved out of the Care Centre in the morning, to avoid them travelling in the heat of the day and were carried in a kelotok (a traditional boat a bit like a motorized canoe). Biruté, Tigor and other staff travelled up later in speedboats. Or at least that was the plan; low water levels meant the speedboats could not get up. They lost two propellers and cracked the hull of one of the boats after colliding with submerged logs. Eventually, the kelotok had to come back for them.

The pictures below show the release from the Care Centre to Camp Rasak and then freedom, once again, in the wild.

These photos show the orangutans being moved from the Care Centre, into the kelotok, then having a few minutes peace on the feeding platform before some other interested orangutans came for a nose.

All the photo's were taken by Uduk, Tigor's deputy, on a camera recently donated to the Orangutan Foundation at our Members and Supporter's Evening in London, in July.

Kusasi a great great ape

I was pleased to read that some of you have seen the PBS documentary “Kusasi from Orphan to King” which was shown on PBS television in the States, on the BBC in the UK and ABC in Australia (I think it may also have been on Animal Planet). I think it is a great film giving you a real insight into Kusasi’s world.   

Kusasi -the old king of Camp Leakey 

However, the second reason I like it is much more personnel; Kusasi has been a large figure throughout my time here.  When I first visited Camp Leakey as a tourist, in 1996, Kusasi was the contender in waiting.  By the time I came back in 2001 he was the undisputed king.  He dominated Camp throughout 2003 but even by then Win was challenging him.  In 2004 twice we had to operate on him up at Camp. 

 

 

Kusasi during an operation at Camp Leakey, Tanjung Puting National Park 

I remember eight of us struggling to lift him; his head alone felt as heavy as a sack of cement.  2005 was little better for him; he broke his arm and had to be moved to the Care Centre where he spent the next year.   By the time he was moved back to Camp in 2006, he was very much “in retirement”. 

 

Kusasi, after his time in the OCCQ, in 2006 

Tom had taken over as king and is still the dominant male, he rarely comes into Camp though.  Kusasi, for his part, is either in Camp or deep into the forest.  He does not go anywhere where Tom might be.  And that is probably very wise. 

 

Kusasi -relaxing (photo by Hugh Sturrock)

I have seen Kusasi relaxing, even looking bored.  I have seen him grab a person, which was frightening and I have seen him fighting other males, which was even more frightening.  He gave Ashley and I the shock of our lives when he entered a small building where we sat.  But I have also seen him grow old.

 

Kusasi - still a magnificent orangutan 

These days he appears thin rather than massive as he did a few years ago and he has lost two of his canine teeth.  It is probably in his best interests if his fighting days are over. That said, even if he is past his prime, in his prime he was unbeatable.  And even now he remains magnificent. 

Tropical Forest Research Station

July has been a busy month, hence my lack of posts (apologies) and it looks set to continue into August. This has definitely been Pondok Ambung’s month. Pondok Ambung is the Tropical Forest Research Station we operate inside Tanjung Puting National Park.

Pondok Ambung is set in a beautiful location on the Sekonyer River, TPNP.

I have already told you of Rene’s study on crocodiles but I think it completely slipped by to tell you that the University of Reading's ‘Summer School’ were here earlier this month. This is the second year, Reading University have run a ten-day field course at Pondok Ambung. It is always great to see students getting out of the classroom and into the forest. I hope it inspires them. They were certainly captivated by the orangutans and gibbons.

Pondok Ambung visitors; orangutans, gibbons, and humans -whose watching who?

And just to prove there are always new experiences to be had, the day Brigitta (who contacted us through Wildlife Direct) was with us at Pondok Ambung, we found a tree that had been absolutely torn apart. You will have seen photos of the damage sun bears can do to trees in one of my earlier posts. Orangutans will also tear off bark to either get at sap or insects. But, on this tree, half the bark had been shorn off and huge chunks of heartwood pulled out. If it was an orangutan or a bear, I would not want to meet them!

It was Rene who gave us the answer: the tree had been struck by lightening (he said there had been an almighty thunder clap and lightening flash the day before). That was why the wood appeared to have exploded outwards. Still it was incredible there was no sign of burning. Despite the downpour, I would have thought a million plus volts would have at least singed the leaves…

Stuck in between two great apes

During last week, when I was in Tanjung Puting National Park, I had a close encounter that reminded me just how impressive these great apes are. Walking down the jetty from Camp Leakey we found our way blocked by Kusasi, who, I can assure you, is quite some bloke!

Kusasi and Tut blocking the way.

Kusasi was the dominant male of Camp Leakey for many years. Tut, a female, sat patiently in front of him; if he was not going to shift neither was she. So we called Abdi who is magical with the orangutans. Abdi simply walked up to Kusasi and shooed him away, much as you or I would a kitten.

Humbled, we thanked Abdi and walked on, only to find Uranus, another cheek-padded male, at the far end of the jetty. The rule with all orangutans is “never within arm’s reach” which means there was no walking past Uranus who has a 2m/7’ arm-span.

Tom, another cheek-padded male - thank goodness he wasn't on the jetty!

Kusasi had by this time returned to the jetty, which meant we could not walk on or go back. I tried my Abdi impersonation but failed dismally. With Uranus, we had to wait him out. It was almost sunset before he sauntered off to make his nest….

Orangutans and Crocodiles

Hello again, sorry for the silence but I have just had another fantastic week in Tanjung Puting National Park. Actually, on Monday I was in Lamandau, on a peat-lands survey, but I was still out of the office and in the forest, which made for a good day!

In case you're wondering where these places I keep mentioning are, here's a map (Pangkalanbun is where our office is).

At Pondok Ambung I caught up with René, the German crocodile researcher, and then spent a wonderful couple of days at Camp Leakey. There were orangutans everywhere! What was great was seeing some unusual things. Foremost on that list was food sharing between two adult females.

Above and below, Rani and Riga - sharing food

Young orangutans will often sample what their mothers are eating. This is part of the learning process; finding out what is good to eat. However, on Wednesday, I watched two adult orangutans Rani and her daughter Riga sharing food. What made this doubly interesting is that it was Riga who was giving food to her mother. There may be some biological reason for this – Rani’s three year old son is obviously Riga’s half-brother but that seems a stretch. Normally, the genetic drivers of caring-behaviour are down the generations, not up them. This could have been a case of dominance; the older female forcing the younger one to submit. However, it is also quite likely that it was a simple act of altruism: Riga had enough to eat so was happy to share with her mother.

The final excitement of the week was finding a dead and half-eaten crocodile. We reported this to René who examined the carcass. He estimated it to have been around three metres in length and was killed in a fight with another crocodile. Almost certainly the other crocodile was bigger.

Sekonyer River, TPNP

Having just bathed in that river it was kind of sobering to know there was a bigger crocodile out there…..

As always thanks for your comments, questions and support of our work. Maciej G, thank you very much for your $50 donation at the end of June. Will try and post again soon - the daily powercuts aren't making it easy!

What do we do with banana trees?

Where did last week go? I spent most of it in Tanjung Puting National Park, having lots of fun and adventures, and only got back to the office on Friday. We are still experiencing lots of power cuts. On Saturday, we had a five hour one, 8 am to 1 pm, which put paid to much serious work. So here I am, Sunday night, attempting to tell you how I spent my week, obviously, without much internet!I went first to Buluh Besar Guard Post in the middle of the Park, and from there, to Pondok Ambung and Camp Leakey, where I met up with Brigitta. However, this all deserves its own post (to come soon), so I will just cut to today. My back garden has been as over-productive as usual and the latest banana tree, to try to outgrow the electrical wire to my water-pump, needed felling. What do we do with banana trees? Give them to Montana.

Montana with his banana tree.

I went to the Orangutan Care Centre & Quarantine with a group of visiting researchers and found the big guy looking unusually bored. He was laid flat out with his massive head resting on his two fists. He didn’t even turn his head as we approached. Once the banana tree was near enough to be on offer, however, he sprang into action in a way that reminded me – yet again – never get too close: He’s quick! The stalk was inside in seconds, and then the leaves. And Montana was one happy orangutan.

Less pleased were the adolescents occupying the next-door enclosure, who wouldn’t normally dare so much as whimper at the adjacent cheek-padded Montana. Today, though, they were happy to demand attention from the visitors. We gave them extra leaves and they were delighted. I even managed to get a smile from one of them (unlike young chimpanzees that will literally giggle if tickled, orangutans seldom express pleasure), getting a full toothy grin was reward in itself.

Me with the adolescents.

Thanks for your comments, Sheryl and Annie, about the paper (which we contributed to) mentioned in my last post, “Distribution and conservation status of the orangutan (Pongo spp.) on Borneo and Sumatra: How many remain?”. I agree, it is important to think positively and I don’t believe orangutans will become extinct. I think the programmes that we, and our partners, are working on in Central Kalimantan, will ensure this never occurs.

Orangutan population declining faster than previously thought…

A very quick post. I'm off to Tanjung Puting National Park and will be back on Thursday. At some point I'll hopefully be tracked down by Brigitta who has her goody bag for the Orangutan Care Centre and Quarantine. At the end of last week the scientific paper, “Distribution and conservation status of the orangutan (Pongo spp.) on Borneo and Sumatra: How many remain?” was published in Oryx – The International Journal of Conservation. Dr. Serge Wich, Togu Simorangkir from Yayorin (our Indonesian partner organisation) and other orangutan conservation experts, published new findings that reveal endangered wild orangutan (Pongo spp.) populations are declining more sharply in Sumatra and Borneo than previously estimated.

It isn't all doom and gloom so have a read of the full press release from the Great Ape Trust website.

Many thanks.

- There is a problem with our blogroll but it should be back up soon.

Thank you!

Stephen is currently in Jakarta so a quick post on his behalf. We have just received our donation's report for the second half of May and we are extremely grateful to following people who have donated towards the Orangutan Care Centre's enclosure repairs; Paula B $200, Maciej G $100, Sheryl B $25 and Hilary B $300. In total we have raised $2,375 which means we are only $625 off our $3,000 target. Thank you to everyone who has supported us with this appeal.

For those of you in the UK you might be interested to know the Foundation are holding a Supporters' and Members' Evening on Wednesday 2nd July, at Asia House in London. Stephen, who will be back in the UK, and Ashley Leiman, Director and Founder of the Orangutan Foundation, will be giving a presentation about the Foundation's projects, achievements and challenges. Please visit our website for more details.

Many thanks,

Cathy, Orangutan Foundation.

Enclosure repaired but more work needed

Once again, thank you very much to everyone who donated to our request for funds to repair the orangutan enclosures at the Orangutan Care Centre & Quarantine. I was there today and can happily report the first round of repairs has been completed and the escapees are now back in their secure enclosure.

The repaired cage is the one in the middle.

And these are the occupants.

This photo was taken one second before he made a grab for the camera!

Unfortunately, there is still more to be done. Montana’s cage is getting thin and the youngsters on the other tower keep trying to pop out. May I ask again for your support? We guarantee all money raised will be spent on fixing the enclosures.

The youngster's enclosure - rusting bars.

It is strange to have an orangutan hanging upside down looking directly at you!

Montana’s cage (above and below)

How long will these bars hold?

And a final photo included for no other reason than I thought this orangutan simply had the sweetest face. Your thoughts?

Sowing the seeds…

My every sense says the forests on the northern border of the Lamandau Wildlife Reserve are in trouble. Already split into thin fingers of forest, separated by degraded areas, it seems these forests are retreating not expanding. However, with the support of local communities, we have chosen this area as a reforestation site. A few days ago I went there with Rene Dommain, the visiting German peat researcher, and we stayed at the very northern point of the Reserve, where we have a guard post, Post Prapat (see map).

Behind the post is one of the fingers of forest. Here there are tall trees, including those species found in deep forest, but they are only 20 metres away from sand. Clearly this is remnant primary forest and the thinner it gets, the more vulnerable it becomes.

Aerial view of Post Prapat with the remnant forest behind.

Rene helped to explain the process and no surprises here – the villain was fire. Whilst he described it as an “anthropogenic impact”, you and I can hear “man made”. The southern part of Borneo is a relatively “young” landscape. The base material is sand, deposited either from erosion of the high interior mountains or during the periods when the area was an ancestral seabed. Over thousands of years, grasses, shrubs, and then trees gradually covered the sand and forests grew.

Fires have had a major impact on this ecosystem. The first fires burning through the shallow humus layer, killing the trees’ roots. With the trees fallen the next fires to occur were even more destructive with subsequent fires encouraging scrub growth. Ultimately this left an exposed layer of sand with the original nutrient rich humus having been destroyed. Presently, these remaining forests are just waiting for the next dry year, the next fire.

The aim of the reforestation programme is not ambitious – even in our wildest dreams we cannot envisage the day when this will be thick forest. What we are trying to do is broaden the forested fingers, reduce the gaps and push the balance in favour of the trees not the scrub.

It is a tall order to regenerate this area, but you know us, we like a challenge!

We have established a tree nursery at Post Prapat. The people from the surrounding communities have been enthusiastic in finding wildings (seedlings harvested from wild seed-fall) to stock it. We will keep the trees in the nursery until their rooting systems are well established.

Nursery

The whole process is hugely resource-intensive and the return may be as little as 50ha (1/2 km2 or 123 acres). But that is hardly the point. The real points are:

• People learn about how fragile these ecosystems are.
• We are demonstrating that protecting the existing forest is much more effective than trying to re-grow it
• By protecting the fragile fringes, you prevent damage spreading to the core

In the case of Lamandau, the forest core is still rich in biodiversity. I led Rene on the 7 km walk southwards from Post Prapat to Camp Rasak. On the way, we saw a few birds and a snake. At Camp Rasak, I was hoping to catch of glimpse of Boni who we are told is seen most days and neither did we see Andi and Sawit, who seem to have gone off together (see post 'More orangutans back in the wild'). However we were fortunate to see Lady Di and her baby.

Lady Di was released into Lamandau in Febuary 2006 and this is her first baby.

It is hard to believe our reforestation programme site is only 7 km away, but without this added protection, this forest and these orangutans would seem a lot more vulnerable.

- PS, Sheryl, you’ll be pleased to know once the eagle, snake and monkeys were out of the traps, I also set the fish free :-)

Feeding orangutans - a new approach

“Why do you do it like that?” “That’s the way it has always been done.”

One of the standards in orangutan rehabilitation is released orangutans are fed on a platform.

Photos showing the feeding platforms that have always been used.

Everyone does it; as do we. But then we got to thinking there has to be a better way. Wild orangutans, especially in Borneo, rarely if ever, feed in groups. So why should ex-captives?

Without the platform though, how do you feed them? By hand is not an option. So we thought “put a bucket on a tree”. No, the orangutans will destroy a bucket in seconds. OK, use a cooking pot. Imagine the noise they would make banging that around, plus they will rip it off the tree! Alright then, use an inside out car tyre as a bucket. Fine, but how are you going to attach it; we don’t want to bore into the tree? Here’s an idea, when you cut off the side walls to invert the tyre, use the off-cuts as straps to hold the tyre against the tree.

Old tyres- they have many uses, if not for fire beaters then as a feeding bucket

So we’re settled: the food goes in the car tyre strapped to the tree. But how do you give them their milk (which many love more than fruit)? Cups – they’ll break, be lost and will become litter. Water bottles – even worse. Let’s try coconuts. Cut the top off, pour the milk in, put the coconut in the tyre; if the orangutans drop it, it will be easy to find and even if we don’t it is hardly litter.

All good then - let’s try it.

Its a good job our assistants are tree climbers too!

The feeding system has been running in Camp Siswoyo for a month now. It is not perfect. More than one orangutan may descend on each tyre. Some still walk on the ground between the feeding trees. We are buying an awful lot of coconuts – the orangutans drink the milk then eat the nut! It is more work on the staff and they have to be quick to get the food out.

But is it better than the platforms? Oh yes. You can ensure a fairer distribution of food. It lessens competition, facilitates giving medication when necessary and it keeps the orangutans feeding in the trees.

The system needs to be tweaked, but as a first attempt at a new idea we are all delighted with the result. And here’s where I have to add a thank you not only to Tigor and his staff for their enthusiasm to give it a go, but also to Jodie and Peter: the endless night’s talking about how we could make individual feedings work were worth it!
