Rhino skilled John Payne labored with Sumatran rhinos in Malaysia from the Seventies till 2019, when the nation’s final rhino died.With no rhinos left to look after, Payne has began working with different species, and lately revealed a e book through which he argues the technique to save lots of Sumatran rhinos from extinction was flawed from the beginning.In an interview with Mongabay, Payne speaks about his new e book, shifting on after the lack of the rhinos he cared for, and his frustration with officers and conservation organizations.
In 2019, the final Sumatran rhino in Malaysia died. Her identify was Iman and ever since her seize in 2014, she had been underneath the care of the Bornean Rhino Alliance (BORA), headed by government director John Payne within the Malaysian state of Sabah.
After her demise, Payne, who’d labored on Sumatran rhinos since 1979 (with an admittedly lengthy break within the center on account of “frustration”), was all of a sudden left with none rhinos to look after, after years of attempting to breed the final female and male in Malaysia.
The disappointment hasn’t slowed him down. He’s now working with different species — Bornean orangutans (Pongo pygmaeus), Bornean elephants (Elephas maximus) and banteng (Bos javanicus) — and he’s written a e book, The Hairy Rhinoceros: History, Ecology and Some Lessons for Management of the Last Megafauna, the place he argues that the technique to save lots of Sumatran rhinos from extinction was flawed from the beginning by poor compromises and stifled time and again by forms.
Among Sumatran rhino consultants, Payne has all the time been recognized for his candor, his acerbic wit, and his typically controversial positions. And he pulls no punches in his newest interview with Mongabay. He criticizes each the rising forms of conservation organizations, and what he sees because the perspective of Indonesian officers for the delays and inaction on Sumatran rhino conservation.
“The drawback was very a lot Indonesia and the worldwide framework not working,” Payne says, including that “it’s surprising at the present time, that Indonesia has its forestry and setting now underneath one ministry.”
He additionally thinks Sumatran rhino are solely breeding within the Leuser Ecosystem, in Indonesia’s Aceh province, on the northern tip of the island of Sumatra. And if he have been in cost, he’d be catching rhinos from there for captive breeding; he’d be gathering egg cells from younger rhinos for in-vitro fertilization; and he’d take into account maximizing beginning intervals by taking rhinos away from their moms as soon as they’re weaned.

For years, Payne was advocating for extra captures of untamed rhinos even when it was a really unpopular thought. Today, his advocacy appears prescient. Not solely has the Sumatran rhino gone extinct from Malaysia in only a couple many years, however it’s practically extinct in Indonesia, the one nation the place it’s discovered at the moment. The most up-to-date estimates places the whole variety of rhinos at lower than 50, unfold throughout three areas. And, if the previous is any information, the true quantity could also be decrease — notice the current information on the doubtless inflated numbers for Indonesia’s different critically endangered rhino, the Javan rhino (Rhinoceros sondaicus).
Given the dire scenario within the wild, and the truth that there are solely 9 Sumatran rhinos in captivity, lots of them are interrelated, Indonesia introduced in 2018 — together with quite a few companions, together with National Geographic — that it might start catching extra rhinos from the wild. A rhino named Pahu was captured a couple of months later, however breeding has by no means been tried along with her.
Not a single rhino has been captured since.
“I’ve this sense: it’s by no means going to occur. Actually, I feel it’s simply speak,” Payne says of Indonesia’s plan to seize and breed extra wild rhinos.
Despite the lack of all rhinos in Malaysia, Payne continues to work in conservation. He’s working with most of the similar colleagues, reminiscent of wildlife vet Zainal Zainuddin, on constructing meals habitats for threatened species in Sabah, together with orangutans, elephants and banteng, a species of untamed cattle.
“With the Sumatran rhino, I’m pissed; I’m not distressed, I’m simply pissed off,” he says.

The following interview has been edited for size and readability.
Mongabay: How did you get began with the Sumatran rhino in 1979?
John Payne: In the times earlier than Margaret Thatcher, the British authorities was very unusual: I acquired a scholarship from the British authorities in 1975 to review macaque monkeys in Malaysia. I spent greater than two years in Peninsular Malaysia within the mid-Seventies. WWF-Malaysia amazingly already existed. It was one of many earliest WWFs outdoors Europe.
So, it was a pure development, which I used to be very pleased with, that once I acquired my Ph.D. in 1979 that WWF was searching for individuals to do fieldwork in Malaysia. I’ve to say at the moment no right-thinking Malaysian would need to do wildlife fieldwork, it was a special period. It was vast open for younger chaps like me in a manner that it actually isn’t anymore. I used to be in the suitable place on the proper time to get a job in WWF-Malaysia.
A survey with the Forestry Department of Sabah confirmed two issues. Number one, that Sumatran rhinos nonetheless existed. That was a debate. And it was on the verge of extinction in 1979 and 1980: there have been simply nonetheless a couple of left.
That consequence got here out after two and a half years of going round numerous forests in Sabah, attempting to map the distribution of the bigger mammals and bigger birds.
Mongabay: You have been on the 1984 assembly that actually kick-started people interacting with the Sumatran rhino in a way more deliberate and typically unplanned methods. What do you see because the legacy of that assembly at the moment, each for rhinos and basically?
John Payne: All the suitable individuals have been there, however right away there was a division. There was [Basel Zoo rhino expert] Rudolph Schenkel saying, “Rhinos [are] part of the setting, we shouldn’t take them out.”
And [conservation coordinator for the Association of Zoos and Aquariums] Tom Foose who I admired significantly — he was an actual pioneering thinker — mentioned, “No, they’re going to get extinct if you happen to depart them there.” That was the essence of that assembly. As you’ll know, the compromise was to catch solely the ‘doomed ones,’ the rhinos that have been least fertile, as we realized subsequently.
So, the legacy? Nowadays, individuals … prefer to construct a consensus, however it means you find yourself with a compromise that satisfies everybody, however is the unsuitable consequence, as a result of it doesn’t obtain the intention.
There have been a number of modifications round 1980 on this planet conservation technique. There was an enormous shift in shifting away from a small variety of devoted, passionate individuals — doesn’t matter the place they’re from — working collectively. Unmolested by the IUCN and unmolested by governments or different NGOs.
From 1984, you possibly can nearly by no means get what you actually need to do due to this [interference]. There’s an odd phenomenon of people being divided into two, proper? This all the time comes out: There’s two [opposing] teams. At the identical time wanting to succeed in a compromise, which doesn’t actually fulfill both. I’ve seen that … again and again.

Mongabay: That assembly made some massive selections, fairly daring stuff on the time. As you say it was a compromise: At the time neither aspect may actually know what was the suitable technique. So as a substitute of going all in on one aspect, they compromised. What do you see because the failures from 1984 to at the moment?
John Payne: I feel one of many rapid ones is there’s all the time these worldwide tensions, proper? U.Ok. and France, Canada and U.S.A. But Indonesia and Malaysia — it’s even worse.
Indonesia regards Malaysia — after all not everybody — however the basic temper in Indonesian governments, politicians, is that Indonesia regards Malaysia as an upstart. And Indonesia is aware of finest.
Just an upstart neighbor. Very small. So tiny as compared of land space, inhabitants measurement, extent of oil palm, every little thing.
Now, when you get two international locations, then you definitely’ve acquired CITES [Convention on International Trade in Endangered Species of Wild Fauna and Flora] in the way in which. Which is usually used as an excuse for inaction. Then you’ve acquired this Nagoya Protocol on who owns organic assets, all this stuff that come into play. And whereas you want a choice inside a couple of weeks, like, “Should Tam [a male rhino from Malaysia] go to Indonesia?” It will get slowed down in forms, CITES and the Nagoya Protocol.
I feel that the Indonesian and Malaysian scenario is perhaps a bit worse than common. But I can foresee that coming in repeatedly.
The IUCN simply doesn’t work on this scenario. There’s simply so many individuals — and people who find themselves well-meaning however actually don’t know the background — and so they come into play. Then the IUCN Asian Rhino Specialist Group, and what was referred to as the Captive Breeding Specialist Group, which is now the Conservation Planning Specialist Group. They don’t actually agree with one another, and neither of them actually are match for function. It’s not towards the people who work there.
They’re simply this accumulation of people who find themselves in the suitable place on the proper time and who don’t have any explicit information of, on this case, the Sumatran rhino.
Somehow it’s a must to have the mannequin, which we will’t do anymore, [where] small teams of passionate individuals [do conservation]. But now they’re already constrained by nationwide laws, CITES, bureaucracies. The IUCN doesn’t assist get by way of that, these obstacles, it truly hinders them, it makes them even worse.
So, it sounds very damaging on the IUCN, and I’m actually.
I’m fairly bitter. Someone at Singapore Zoo mentioned to me the opposite day, “Yes, John Payne, you’re nonetheless very bitter.” Yes, I’m. The IUCN didn’t assist. I don’t know what the answer is.

Mongabay: You talked about this within the e book: how the variety of stakeholders and the bureaucracies make it extra sophisticated and make decision-making tougher. When you headed BORA and have been working with the rhinos, it appeared such as you had a number of independence and a number of latitude, or is that simply the way in which that you simply talk?
John Payne: Well, it’s an fascinating level. No, I did. I’ve to say it’s all the time straightforward to criticize governments. But I did have latitude. I feel I used to be fortunate as a result of I’ve been in Malaysia so lengthy. And I’m older than most individuals in authorities, so routinely they have an inclination to not be fairly so harsh to me as they could have performed with youthful upstarts. I feel it was to some extent luck, however Malaysia, each at nationwide stage and the Sabah stage, have been truly fairly good.
The drawback was very a lot Indonesia and the worldwide framework not working.
For instance, in my time, let’s say 2009 to 2018, there have been three cupboard selections [in Sabah]. The chief minister and the ministers acquired collectively and mentioned, “OK, we approve to seize rhinos from Danum Valley.” That was performed pretty simply, however that’s partly as a result of Sabah is one unit. It’s not like an enormous factor like Indonesia. It’s all the time fortunate in that sense.
Sabah is a pleasant small unit, however even at federal stage we had a little bit of luck. The federal stage shortly latched on, seeing how the wind was blowing in 2014-15, they agreed that assisted reproductive expertise must be launched.
Somehow the Malaysian system with endangered species appear to work higher than it does in Indonesia.
It’s surprising at the present time that Indonesia has its forestry and setting now underneath one ministry.
There are numerous hierarchies in Indonesia’s ministry. There are 10 or 11 directors-general, starting from schooling, plantations, fireplace management [etc.]. There is one for conservation out of all of these directors-general. Then underneath that, there’s the biodiversity part. Under that comes the parks and species. Under species — all of the Indonesia species, some of the biodiverse areas of the world — and there’s nothing particular for the rhino. It’s proper on the backside of the hierarchy at nationwide stage.
I feel that’s one cause, not the one cause, however it’s a stark distinction between Malaysia and Indonesia. Despite Indonesia’s prominence as a biodiversity space, there’s no particular division about endangered species. It’s a tiny little, not even a division, it’s a part of a biodiversity division in a particular ministry.

Mongabay: One of the details you make in your e book is that there was a lot consideration and cash paid to issues about habitat loss and poaching for the Sumatran rhino. But the true drawback, in your thoughts, is there have been simply too few rhinos. Can you unpack that a little bit bit for us?
John Payne: Sumatran rhino habitat on the finish of the Pleistocene round 18,000 years or so in the past was effectively double what it’s now [before sea level rise].
The South China Sea was largely dryland and swamp, so it might’ve had all these tapirs, tigers, rhinos, elephants operating round there. So, the pure rise in sea stage from 18,000 years in the past to five,000 years in the past worn out half — and possibly the higher half — of the habitat for these giant mammals.
Then extra habitat loss in all of the lowlands as a result of unfold of people rising rice.
The incontrovertible fact that the primary specimen of the Sumatran rhino was shot in Sumatra isn’t a surprise, as a result of that’s in all probability the place the most important inhabitants was left 200 years in the past. But my level was: We solely have a couple of % of the unique habitat left 100 years in the past, and by 1980 it was lower than 1% of the habitat. And crucially it’s the worst habitat, as a result of as you’ll know, giant mammals all the time have hassle in tropical rainforests. There’s not a lot meals productiveness, and so they get highly regarded as a result of it’s humid.
The lack of habitat was trivial by 1980.
Mongabay: Why do you assume the give attention to poaching was additionally misguided?
John Payne: I discover that extra difficult. To reply that query, when the species is in very low numbers, the priority actually must be in precept extra geared towards methods to improve births quite than lower deaths, as a result of every little thing dies.
With giant mammals, the previous couple of years of their life are typically infertile anyway: both they’ve kidney illness, or they’ve run out of sperm manufacturing. You’ve acquired that window of time, which for Sumatran rhinos can be perhaps six years to 25 years on the most. The emphasis ought to have been on methods to improve the births.
Anti-poaching means you decelerate the demise charge, however you’re not addressing the beginning charge in any respect. I feel the emphasis ought to have been on methods to improve births. Not straightforward, proper?
There are a couple of digicam entice photos of child rhinos over the past 40 years, however the demography was largely outdated animals. I hope that illustrates the purpose a bit.
Mongabay: Can you speak a little bit bit concerning the Allee impact and extinction debt?
John Payne: Allee impact is to do with a optimistic correlation between inhabitants density and reproductive health.
In basic, the extra dense the inhabitants, the extra reproductive health there may be. That applies on the inhabitants stage, and particular person … If there are many animals, each animal has a mate selection … You can maximize reproductive charge as a result of you will discover a mate any time. Crucially, it’s to do with the density quite than numbers [of the animal surviving in total].
Another factor that irritates me is that this obsession with numbers. How many are left? It doesn’t actually matter. It’s whether or not they’re multi function space or not. The inhabitants density is the important thing factor. And as soon as it goes beneath what you name a usually regular vary, then you definitely begin to get fewer and fewer births as a result of men and women aren’t assembly one another. Then you get the reproductive pathologies coming in.

Mongabay: Right now, the one place the place persons are saying that there is perhaps a viable inhabitants is in Indonesia’s Aceh province.
John Payne: Indeed, sure.
The remaining rhinos the place there’s nonetheless proof of breeding within the final 10 years is within the Leuser Ecosystem. If you ask the Leuser Conservation Forum, which I love significantly as in all probability probably the most hardworking and competent NGO in Sumatra, they’re satisfied there’s nonetheless plenty of rhinos and so they’re breeding and there’s much more rhinos out within the hills.
But I actually consider they’re unsuitable that the inhabitants is known as a cluster. I’m sure it’s a lot fewer than [in the 1970s]. It’s simply because each different cluster has the identical factor: Every cluster of Sumatran rhinos goes down and down and down. It doesn’t go up.
That [Leuser] cluster, in my opinion, will need to have gone down simply to reflect the demise of different clusters. I feel it’ll go extinct. Why would numbers improve, actually? There’s no cause to assume why the numbers have elevated. At finest they’ll keep steady.
So, if you happen to have a look at extinction debt and species-area curve, you anticipate if you happen to lower habitat by 50%, you anticipate 10% of species to go extinct. If you narrow down habitat by 90%, you anticipate 50% of species to go extinct. Crucially, it doesn’t occur instantly. It’ll play out over 100 years or so.
Did you ever go to Sepilok [orangutan rehabilitation center in Sabah]?
Mongabay: Yes, I did.
John Payne: I believed you may. That’s 4,300 hectares [10,600 acres], proper?
The final elephants have been there in 1981 after which they simply disappeared. There aren’t any indicators of clouded leopards [Neofelis diardi] from quite a few digicam trapping within the final 10 years. You’d anticipate the elephants, clouded leopards and bears [Helarctos malayanus] to go extinct. But it’ll take 100 years earlier than all these species you anticipate to go extinct. It’ll take many years and even 100 years to seek out if the final one dies. It gained’t all occur all all of a sudden. That’s my level. Hence that extinction debt, that concept that it’s worthwhile to wait a very long time for that debt to play out and all these species that you simply anticipate to vanish to go extinct in that space, whether or not it’s Sepilok or Sumatra.
Zainuddin with Puntung, a day after her seize, nonetheless contained in the forest of Tabin Wildlife Reserve. Image courtesy of John Payne.
Mongabay: This poses an fascinating query. I’m curious if you happen to’ve considered when the extinction debt hit for the Sumatran rhino? Did it hit within the nineteenth century? Did it hit within the twentieth century? By the time if you began working with them in 1979, do you assume that with none human intervention there was doubtlessly no likelihood? Do you assume that there have been perhaps some populations that would have survived had they not been hit by poaching or had there not been deforestation?
John Payne: Curiously, I haven’t actually considered that earlier than. Oddly, it’s nearly a elementary query, isn’t it? To reply it very ballpark: truly, it in all probability occurred a couple of hundred years in the past with the Sumatran rhino. Thinking again to my earlier feedback proper about Sundaland dropping all its lowlands after the Pleistocene and leaving the rhinos within the very infertile slopes.
Leuser is a bit totally different as a result of it’s volcanic … so it’s a way more fertile soil, so they may in all probability dangle on for much longer. I consider that point scale, I’d say in all probability that was taking part in out a couple of hundred years in the past.
Thinking much more clearly, rhinos have been within the Riau province on the east coast of Sumatra, which may be very massive deal, due to APRIL [a major pulp and paper company] and all these massive companies reducing down the entire space within the Nineteen Nineties. There was clearly fairly a dense inhabitants in Riau within the Nineteen Fifties when the 2 teams from Denmark and Switzerland tried to catch them for European zoos.
It seems to be like about seven to 9 rhinos have been caught pretty simply in floor traps … implying that the inhabitants density was excessive. It’s swampy, very flat land in Riau, which is now underneath acacia plantations. That inhabitants density of rhinos was in all probability excessive simply by luck. Didn’t have anybody dwelling there besides on the principle rivers.
Where does that depart us logically? You may both think about that in the event that they’d been left there with no poaching, they could nonetheless be there, however you can additionally think about perhaps that what I’ve mentioned earlier — the productiveness, their vegetation have been poor — it is perhaps they have been in a protracted course of over a couple of lots of of years to extinction there.

Mongabay: Let’s look a little bit bit on the future. There’s a plan now in Indonesia to exit and seize some extra rhinos. They’ve been speaking about this for a couple of years. I do know COVID-19 halted a number of the motion on that, however they’re constructing a brand new facility. Do you assume that’s the proper name at this level? Is there the rest that you’d be doing?
John Payne: I’m not being over-cynical … as a result of the intent to seize rhinos in Sumatra has been a number of years now. COVID is a handy excuse, since I’ve this sense: it’s by no means going to occur. Actually, I feel it’s simply speak.
I actually consider, based mostly on my expertise, that the one place to get wild rhinos now that may breed is in Leuser.
There’s the fiasco of the rhinos in Kalimantan [Indonesian Borneo]. There was a multimillion-dollar challenge to construct this monumental sanctuary with a mosque and quarters in the midst of nowhere. You do not forget that one rhino died within the entice, after which there was one other one, [Pahu]. I’m informed that she’s going to be moved to Taman Safari [a zoo] in Bogor [south of Jakarta] as a result of they’ll’t discover any extra rhinos in that space anymore, which was kind of predictable.
Even there it was apparent to an skilled observer … They have been each outdated females. You may see the numbers are very low. There’s no signal of breeding within the final 10 years. That in all probability was by no means going to be very helpful.
If it was as much as me, I’d say go all out to catch rhinos from Leuser. Technically tough. Yes, it’s a distant, steep space, however our two final feminine rhinos [in Sabah] got here out by Sikorsky helicopter, nearer and due to this fact simpler than the Leuser hills and valleys, however not that totally different. In my view, it’s a greater danger to go away these rhinos in Leuser the place the expertise is small clusters of rhinos decline to extinction in every single place else that’s occurred. Whether it’s poaching or not, doesn’t actually matter. That’s empirically the story. Catch them now whether or not there’s nonetheless a couple of left.
There is perhaps a small variety of fertile females nonetheless breeding in that valley.
Frankly, it doesn’t actually matter if new-caught rhinos are in Aceh or Way Kambas [the captive-breeding facility in southern Sumatra] so long as it’s a part of one program. You transfer one or two round once in a while.
Another factor as you could know, usually, child toddler mammals have a number of egg cells already there lurking away of their ovaries. You may do two issues. One is, you can get them out when the animal continues to be younger and wholesome and do in-vitro, which is now doable with rhinos. It’s doable to make embryos within the lab.
The different factor is de facto — that is once more coming in for criticism — is [to] actually maximize the beginning charge, so put the male and the feminine [together to breed] after they’re fairly younger: 4 years outdated, quite than wait until they’re 10 or 12.
Put them collectively early, and if there’s a beginning, take the infant away inside lower than a 12 months. Now at Way Kambas, they hold the infant with the mom till it’s 3 or 4 or 5 years outdated. In the wild that may occur, however it suppresses the [mother’s] estrus cycle so long as the infant’s nonetheless there attempting to get milk.
As you could recall from Nico van Strien [late Sumatran rhino expert] and Terry Roth [who cracked the code on how to breed Sumatran rhinos in captivity at Cincinnati Zoo], they reckoned the shortest beginning interval could possibly be about three years. Zainal Zainuddin [a vet and expert on Sumatran rhinos who works closely with John Payne] believes it could possibly be even much less if you happen to take away the infant when it’s weaned. You may doubtlessly have a one-year beginning interval. There’s no cause why not. Again, you get why snowflaky individuals say it’s not pure, however it’s doable. Mammals evolve to breed. You are enhancing, in my opinion, what nature may do anyway.
Catch, maximize replica charge, and why not as a precaution, hold frozen embryos simply because it’s doable — which after all it gained’t be sooner or later, when there’s hardly any rhinos left to hold or current embryos.

Mongabay: Is there something that provides you hope for the long-term way forward for this species?
John Payne: I don’t know if you happen to comply with the story of the northern white rhino, and the very fact there’s now embryos. It’s a lesson that one could make in-vitro embryos, which can sooner or later be helpful.
My basic level is that reproductive and cell biology are advancing. One of the pioneers is an Indonesian, Arief Boediono. [He’s] an Indonesian who’s a vet.
There’s experience in Indonesia. I wished to make that time. There’s experience in Indonesia, not essentially on this assisted reproductive expertise, however in a extremely, on-the-ball, advanced-thinking, prepared to check out new issues.
Mongabay: You labored with the Sumatran rhino now in Sabah for 40 years. What do you do after the species that you simply’ve labored with goes domestically extinct? What did you flip to? How did you deal with that?
John Payne: Busier than ever. With the Sumatran rhino, I’m pissed; I’m not distressed, I’m simply pissed off.
Zainal and I work very effectively collectively, and we’ve got a superb tutorial, Abdul Hamid Ahmad, who’s our chairman in BORA. We determined to remain on at BORA, and we’re very bullish. Among the issues we’re doing now’s beginning a program to plant the favourite meals of orangutans in oil palm plantations in Sabah within the perception that the residual inhabitants doesn’t have to be moved out. In truth, it shouldn’t be, it ought to keep there. Orangutans are actually sensible: if they’ve meals, they’ll survive … There are little patches you can stuff with orangutan meals vegetation. We’re doing that within the expectation that orangutans in the long run can dwell in a blended oil palm and forest for its panorama.
The different is the elephant. The numbers are going up, though everybody denies it, however the numbers are going up. The drawback is now the battle with people is getting worse quite than higher. One of the explanations is that there are extra elephant meals outdoors forest reserves than in protected areas. And that’s not solely oil palm, it’s grass. They go for monocultures. We began planting particular areas with grassland for elephants in Tabin Wildlife Reserve. It’ll be a sluggish course of, however the basic considering is it’s worthwhile to put much more elephant meals assured so they arrive again. They know there’s plenty of lush grass, there’s synthetic mineral blocks. There’s a pond close by, with water even within the dry season.
So that habitat in the long run turns into at the least as enticing as going out into villages and getting harassed.
Similar, however totally different, the wild cattle of Malaysia, the Bornean banteng: we’re rising pastures for these as effectively. Similar factor, there’s no contact with people, however their limiting issue within the distant areas is identical factor: there may be not sufficient grass. Even extra so as a result of they’re bovids, so that they want grass and there’s simply not sufficient grass within the totally different sorts of forest within the north.
So, we’re beginning within the final two years to plant grasses in Tabin and in Perak state in west Malaysia, the place there’s wild cattle species. We are already proving it with digicam entice photos. They want grass. Their limiting issue, once more, just isn’t poaching, they simply don’t have sufficient meals. And we see it with the physique situation of the cow and their beginning charge. With grass, they begin breeding extra ceaselessly and their physique situation is best.
In a way, it’s a humorous lesson from the Sumatran rhino, isn’t it?
How do you increase the numbers? In this case, make certain they’ve plenty of meals in suboptimal habitat in protected areas.
