SPECIAL EDITION NEWS RELEASE
One mouth for Lake St Lucia system
Background Information Document BID 2012/09
iSIMANGALISO WETLAND PARK AUTHORITY
The strategy to allow the uMfolozi and Lake St Lucia estuary mouths to join to form a combined mouth is progressing well. The linking of the two systems via the beach spillway resulted in approximately 16.4 billion litres of fresh water reaching the Lake St Lucia estuary and lifting water levels at the end of the dry winter period. The early spring rains and natural breaching of the uMfolozi mouth, which resulted from the one-in-five-year flood, have created a marine connection for the system. The recent events are both natural and positive and are part of the much broader long term strategy to restore estuarine function to this important nursery for fish and invertebrates. Key to this is to allow these systems to function as naturally as possible. With the Lake St Lucia and uMfolozi systems joined, modelling shows that their combined mouth will be open more often than it is closed.
However, it is unlikely that there will be a rapid recovery of the Lake St Lucia system - one of South Africa’s most important estuarine systems and Africa’s largest estuarine lake (approximately 32 000 ha). Together with reduced water inflow from nine years of below average rainfall, the lake has had little or no water from the uMfolozi river for the past 60 years. The Lake St Lucia system requires large volumes of water before it is able to function within a range considered to be natural and indicative of a healthy system. Over the next two to three years the level of the water in Lake St Lucia will be highly dependent on rainfall, the amount of which will determine how quickly the level rises. This means that a large flood could fill the system quickly or that under average rainfall conditions, it could take a number of years.
Underpinning this management strategy implemented by iSimangaliso in partnership with Ezemvelo KZN Wildlife, is the work undertaken through the iSimangaliso GEF project. In its final stage, the Project is investigating and formulating a long term solution to restore, as far as possible, the natural hydrological and ecological functioning of this important system. The aim is the ecological restoration of Lake St Lucia and the protection of iSimangaliso’s World Heritage Site values such that ongoing human intervention is no longer needed or minimized. Phase 1 of the GEF project included a scientific review workshop attended by 41 scientists including hydrologists, estuarine ecologists, estuarine hydrodynamic specialists, social scientists and geologists, and stakeholder and public meetings. This research collaboration has already paid off with the new science guiding the ‘combined mouth’ strategy for Lake St Lucia that is currently being implemented.
iSimangaliso will continue to interact with and keep stakeholders and interested parties informed of the state of Lake St Lucia and progress made with the GEF Project. (For more information visit www.iSimangaliso.com and download ‘Lake St Lucia: understanding the problem and finding the solution’.)

Beach spillway transfers water
The beach spillway, created to expedite the reconnection of the uMfolozi River with the Lake St Lucia estuary, was opened on 6 July 2012. (For more information on iSimangaliso’s strategy to let the uMfolozi River and Lake St Lucia rejoin refer to the textbox at the end of the document: ‘2011 New lake St Lucia Estuary Management Strategy’).
Between 6 July and 7 September 2012, the water flow through the spillway, as well as the water levels and salinity within the Lake St Lucia estuarine system have been monitored closely by park staff. The monitoring has indicated that the spillway was extremely successful in transferring a large volume of water from the uMfolozi catchment to Lake St Lucia while the mouth was closed.
Plate 1: The beach spillway transferred an estimated 16.4 billion litres of water from the uMfolozi River to Lake St Lucia over 8 weeks.
The amount of water transferred by the spillway during this period was dependent on rainfall in the uMfolozi catchment and by the end of winter the volume of water flowing down the uMfolozi river was significantly reduced. Analysis of the flow data has enabled us to estimate that the total volume of water transported by the beach spillway was approximately 16.4 billion litres while the uMfolozi river mouth was closed.
Table 1: Total volume of water flowing into Lake St Lucia through the spillway during the closure of the uMfolozi mouth
The volume of water transferred through the spillway raised the water level in the Lake St Lucia Narrows by 33 cm. Once levels were raised, the water began to flow northwards from the 20 km long Narrows into Makakatana Bay and the southern portion of the lake.
Spring rain
Early spring rains began with an intense and rapid-forming cut-off low pressure system centred over the eastern part of the country on 5 September 2012 (see weather map below).
Figure 1: Rainfall forecast for 5 September 2012 from SAWS
This weather system resulted in significant amounts of rain falling throughout the park during 4 – 7 September 2012 (see table 2 below).
The uMfolozi River water level rose rapidly and brought increased volumes of water through the spillway for a period of 24 hours before breaching directly into the sea. The spillway was substantially widened and deep water flowed bank-to-bank into Lake St Lucia Estuary (see plate 3 below). By uMfolozi standards this event was a relatively small flood (a so-called one-in-five year flood). The steady rain falling over the catchment lifted the uMfolozi water levels over a 24 – 36 hour period. Rather than bursting out to sea along the most direct route, the rising water levels overtopped the beach sand barrier at a low point and the river opened to the sea in the early hours of 8 September 2012 (see plate 4 below).
Plate 2: The beach spillway was substantially widened by the early spring rains. It connects the uMfolozi, Lake St Lucia and the sea. This photograph was taken during the spring high tide on 17 September 2012
Once the uMfolozi River breached, water flowed southwards from the Estuary through the beach spillway and out through the open mouth. This occurred until the water level in the Estuary dropped to levels below the base of the beach spillway. In the final account, the water level in the Narrows has risen by a total of 25cm, with a corresponding increase in the rest of the Lake, and levels are the highest they have been since November 2011. In this configuration it is likely that the beach spillway will continue to intermittently connect the uMfolozi, Lake St Lucia and the sea. The extent to which this will occur is dependent on sea condition and wave action, the water levels in the Lake and the uMfolozi river and tidal influence.
Plate 3: The now-open uMfolozi River mouth has linked Lake St Lucia to the sea via the beach spillway.
Since these first spring rains broke the winter dry period further rains have been received over the weekend of 14–16 September 2012. These have resulted in good rainfall being received across iSimangaliso (see table 2 below).
Table 2: Early spring rainfall figures in iSimangaliso
Salinity values of Lake St Lucia
These two rainfall events have brought much needed water to fill wetlands and pans, and to recharge groundwater levels. Rivers like the uMkhuze, uMphathe and Nyalazi that flow directly into the Lake are also flowing strongly. Combined with the effect of direct rainfall on the Lake, salinities throughout the system have decreased substantially with the highest salinity values in the north of the system at 53 parts per thousand (Listers Point) and 2 parts per thousand in the Narrows.
Figure 3: Salinity values of the Lake St Lucia system from December 2011 to 14 September 2012
Estuarine functioning
The current configuration of the uMfolozi and Lake St Lucia mouths, connected by the beach spillway, marks the beginning of a period of marine connectivity. Sampling carried out on either end of the spillway by researchers from the University of Zululand in August 2012, confirm this. Juvenile fish that entered the uMfolozi River through its open mouth last year were found to have moved through the beach spillway into the Lake St Lucia system. These fish species are estuarine dependent species that need estuaries to complete their life cycle. Prawns and estuarine dependent fish species like grunter, stumpnose and cob spawn at sea and come into the estuary when they are small juveniles (approximately half a centimetre in size). They leave the estuary as sub-adults. Estuarine residents like goby are spawned and remain in the estuary for their whole life cycle.
Park staff will continue to monitor the fishing effort in the mouth area and members of the public are requested to respect conservation measures implemented to assist the fish and invertebrate stocks to recover.
Birds
Biannual monitoring that takes place as part of the national Coordinated Water Bird Counts (CWAC) project shows that healthy numbers of many species of birds currently use the Lake St Lucia system, with 35 000 water birds counted during the last monitoring trip undertaken by Park staff.
Figure 4: Bird numbers across the St Lucia system from the July 2012 CWAC count
For example, flamingos are currently found in the northern parts of the lake in large numbers indicating the presence of shallow brackish water that supports the type of food they eat. White pelicans are also present in large numbers and have bred successfully with more than 700 large chicks found in this sheltered breeding colony.
Plate 4: Pelicans at Charters Creek
There is also a large number of bird species using the intertidal areas at the open mouth for feeding and resting. Migratory waders such as curlew sandpipers, whimbrels and ringed plovers have recently arrived from the Palaearctic for the summer. They are feeding on invertebrates living in the sand and mudflats, such as worms and small crustaceans. Pelicans and herons are feeding in the shallow water on fish and prawns. Large flocks of terns, predominantly swift terns but also including little terns, Caspian terns and the rarer vagrant Sooty terns are also found in large numbers. The sooty tern has drawn a lot of interest from bird-watching enthusiasts and has been reported on the South African Rare Bird report over the past few months.

Where to now?
The strategy to allow the uMfolozi and Lake St Lucia estuary mouths to join to form a combined mouth is progressing well. The linking of the two systems via the beach spillway resulted in approximately 16.4 billion litres of fresh water reaching the Lake St Lucia Estuary and lifting water levels at the end of the dry winter period. The early spring rains and natural breaching of the uMfolozi mouth, which resulted from the one-in-five-year flood, have created a marine connection for the system. The recent events are both natural and positive and are part of the much broader long term strategy to restore estuarine function to this important nursery for fish and invertebrates. Key to this is to allow these systems to function as naturally as possible. With the Lake St Lucia and uMfolozi systems joined, modelling shows that their combined mouth will be open more often than it is closed.
However, it is unlikely that there will be a rapid recovery of the Lake St Lucia system - one of South Africa’s most important estuarine systems and Africa’s largest estuarine lake (approximately 32 000 ha). Together with reduced water inflow from nine years of below average rainfall, the lake has had little or no water from the uMfolozi River for the past 60 years. The Lake St Lucia system requires large volumes of water before it is able to function within a range considered to be natural and indicative of a healthy system. Over the next two to three years the level of the water in Lake St Lucia will be highly dependent on rainfall, the amount of which will determine how quickly the level rises. This means that a large flood could fill the system quickly or that under average rainfall conditions, it could take a number of years.
Underpinning this management strategy implemented by iSimangaliso in partnership with Ezemvelo KZN Wildlife, is the work undertaken through the iSimangaliso GEF project that is investigating and formulating a long term solution for the hydrological and ecological functioning of the Lake St Lucia system. The aim is the ecological restoration of Lake St Lucia and the protection of iSimangaliso’s World Heritage Site values such that ongoing human intervention is no longer needed or minimised.
The first phase of this component is complete and involved the analysis of the possible management options that will promote restoration of the system. These options have been presented for comment and input to scientists and other stakeholders, such as local communities and ratepayers, the floodplain sugar farmers, the tourism operators, government, NGOs and other interested parties. The stakeholder events included a scientific review workshop attended by 41 scientists including hydrologists, estuarine ecologists, estuarine hydrodynamic specialists, social scientists and geologists.
The project is in its final phase, which includes the appointment of the team of specialists to provide detailed analysis of the selected options. This process will take ecological, social, financial, political and economic considerations into account, and will include environmental authorisation. The consultants’ work is expected to take 12 months. A portion of the GEF budget has also been set aside to finance the implementation of the preferred option. iSimangaliso Wetland Park staff and scientists will continue to monitor the status of the system and its response to the current management intervention
iSimangaliso will continue to interact with and keep stakeholders and interested parties informed of the state of Lake St Lucia and progress made. (For more information www.iSimangaliso.com and download ‘Lake St Lucia: understanding the problem and finding the solution’.)

More great news for KZN North
Black rhino introduction – Playing Cupid
iSimangaliso Wetland Park’s Eastern Shores section has received a boost to its existing black rhino (diceros bicornis) population with the recent introduction of a young pair. Both were abandoned by their mothers under different circumstances, leading to them being removed by Ezemvelo KZN Wildlife staff with a view to re-homing them. The male, now about 4 years old, has been in a large boma in the company of a long-suffering goat for two years, enabling him to grow sufficiently large to fight his own battles when he seeks out his own territory. He originated from Mun-ya-Wana (Phinda) where his mother, harassed by a cantankerous male over turf wars, turned tail and left him and a sibling to their own devices. The younger sibling died but he continued to make good progress under the watchful eye of dedicated Ezemvelo staff at Hluhluwe-iMfolozi’s Game Capture Centre.
Goats make great companions for young rhinos..until the latter grow up and play becomes a bit rough!
Prior to his release into the wilds of iSimangaliso the male was moved to a boma in iSimangaliso to allow him to ‘acclimatise’ to different surroundings.
After a few weeks the male was darted and gently lifted out of the boma to be released into his new environment.
Fortuitously for him, during his waiting period in the iSimangaliso boma, a young female at Ithala Game Reserve was reported as similarly abandoned by a notoriously “bad mother”, known for her non-maternal tendencies. Although less than three years old, she was mature enough to survive independently and declared an ideal mate for the male, and a plan was made to set them on the course for a potential relationship.
Ezemvelo KZN Wildlife Chief Veterinarian, Dr Dave Cooper and Wildlife Act’s Chris Kelly fitting a foot collar to the female black rhino. This will enable her movements to be tracked with data regularly uploaded to the computer monitoring system.
The female black rhino being let out of the crate.
According to Ezemvelo KZN Wildlife Chief Veterinarian, Dr Dave Cooper, “Black rhino are unfortunately their own worst enemies. They are highly intelligent, fiercely territorial, inquisitive and tend to attack first and ask questions later. Single males are a nightmare for us because they cannot be introduced into an existing population – that would be their death warrant. And of course, a lone male is not a happy chap either. iSimangaliso already has black rhino but has plenty of space and ideal habitat for more, and an area was chosen some distance from the known population in the hope that he would not encounter opposition in the near future.
With the attraction of a nubile young rhino-wench, we are holding thumbs that they will find each other to be good company and form their own new territory and perhaps start a family.”
The relocation went off without a hitch, and it seemed that Cupid was spot-on as their spoor confirmed that the two had met up. Lucky guests on two different concessionaire night drives unexpectedly encountered the animals the following night; however the female decided to do a bit of extra sightseeing, surprising park staff with her unexpected midnight grid crossing from the main Park into the Game Park section of iSimangaliso later that night, as well as iSimangaliso CEO Andrew Zaloumis on his early morning cycle (which he quipped afterwards “turned out to be a faster ride than usual!”). She was hastily re-caught by the Game Capture team and once again placed in the bosom of the Eastern Shores, with extra measures in place to deter a repeat escape.
Ezemvelo KZN Wildlife Game Capture Officer-in-Charge, Dumisani Zwane, eases the female onto a truck to be taken back into the Eastern Shores after her nocturnal wanderings.
Due to the current wave of rhino poaching throughout South Africa, security in iSimangaliso is paramount with staff on full alert. Both rhinos have been fitted with foot collars, donated by Wildlife Act who undertake tracking and monitoring activities in iSimangaliso, and they are being closely observed to ensure their safety.
Andrew Zaloumis said, “We have an abundance of big game including buffalo, elephant, hippo, crocodile and rhino – some of the many attractions in this fantastic section of iSimangaliso. We welcome visitors to enjoy the experience and to remain vigilant and aware of their surroundings. If one is fortunate enough to encounter black rhino on a game drive, drivers should retreat and maintain a safe distance (at least 30m) as black rhino are rather fond of using cars as punching bags,” he said. He also gave thanks to Ezemvelo KZN Wildlife’s Game Capture team for their efficient and flawless relocation as well as their quick reaction to the brief “escape”.
Visitors are reminded to heed park rules and signage, and be aware that even in areas where it is permitted to exit vehicles, such as the viewing decks, picnic sites and hides, this is always at the visitor’s own risk.

John Hume.
John Hume was born in the Karoo in South Africa but grew up in Zimbabwe (then Rhodesia). He started his career as a farmer but left Zimbabwe in 1982 and returned to South Africa. His business was in holiday resorts and in 1992, he bought Mauricedale Game Ranch in the Lowveld region of South Africa to retire.
Here, he started game ranching in an extensive wildlife system and his emphasis was on rare and endangered species. He bought a few rhinos early on but over the years developed a great passion for these gentle animals.
Today, at the age of 70, he devotes 95% of his time to breeding rhinos in both intensive and extensive systems and he is South Africa's largest private rhino owner and breeder. He has had massive success with their breeding, is extremely knowledgeable about these animals and is deeply concerned over the plight that they are facing.

--------------
John, how, why and when did you start farming rhinos?
It was always a dream of mine to retire on my own game ranch. I bought a game farm in South Africa in 1992 and started ranching with mixed game, including rhinos, Sable, Roan, Buffalo, small antelope and a range of other Bushveld species.
How many rhino do you have now, and how many did you start off with? How has the poaching affected your rhino?
I have over 800 rhino now and started off with 5 rhinos. I have lost 9 rhinos to poaching over the past few years.
How important is South Africa's conservation model of private ownership and sustainable utilisation?
Extremely important. South African conservation areas cover about 28 000 000ha, of which the private sector owns about 20 500 000ha – about 75% of conservation land. The economic yield to GDP from wildlife ranching was almost R8 billion in 2008/2009. These ranches rely primarily on hunting revenue and to a much smaller degree, eco-tourism. Sustainable utilization is the backbone of the existence of this sector.
When was trade in rhino horn banned, and what were the poaching figures before said ban was implemented? How did the ban initially impact upon private owners?
International trade in rhino horn has been banned since about 1975. Many countries were (and still are) allowed to trade in it internally.
In February of 2009, the national moratorium on rhino horn trade became law in South Africa. For many years before this, poaching figures were minimal, less than 30 rhinos per year. In 2009, 122 rhinos were poached; in 2010 – 333; in 2011 – 448 and this year, we have already had over 460 rhinos poached.
This national moratorium prevented private rhino owners from selling their rhino horn stocks legally and effectively dried up the legal supply of horn.
What contribution do you personally feel you have made to rhino conservation in South Africa?
I have bred 460 rhinos since I started and I plan on breeding 200 rhinos a year from now on.
How would a legalised trade work?
This is a discussion in and of itself but we support the view proposed by Mr. Michael Eustace, which we will touch on very simplistically here: An ethical legal trade in rhino horn should be controlled by a Central Selling Organisation. This organization would broker sales to partners in consumer countries. All horn would have to be registered through a database such as South Africa’s RhoDIS (Rhino DNA Index System) and marked and quotas proportionate to the ownership of rhinos would be determined. Only registered suppliers would receive payment for horn. It is imperative that these sales are sustainable. The intention is not to flood the market and encourage speculation responses from consumers. A few regular sales (perhaps 4 or 5 a year) should take place at a secure venue.
How much will the trade drive the value of rhino horn down? Let’s say that street value at present is USD 65,000 per kilo, (source - www.iol.co.za/business/
This is an exceptionally difficult question to answer. The important aspect here is that legal horn prices force the illegal market prices down to unsustainable risk levels. It would be very important to have strict legislation in place for offenders, to support this concept.
Ideally the CSO would have the capacity to control market prices – lowering them enough to discourage speculators and by varying prices when necessary to disrupt the illegal market. Also, history has proven that a free market situation works, as it finds its own levels. We would have to consider both of these options in the mechanics of the rhino horn market.
Even if there was a drop by say, 10,000 USD per kilo, privateering would continue to be a profitable business, especially as dealers will use the mystique of a wild poached rhino to sell at a higher price. (Ie wet horn vs dry horn having increased powers, desirability etc) How much of a drop in value will it take to stop poaching, and if this happens, will it still be a profitable business venture for private owners?
At this point, private rhino owners are not receiving any return at all on their horn so anything they may receive from it would be more than they are receiving at present. Any reasonable and intelligent rhino owner would then not dream of killing his animals when he could be producing about 60kgs of horn during a single animal’s lifetime. Rhinos would be worth more alive than dead, which would reverse the current trend. More people would be encouraged to breed, conserve and protect rhinos, leading to an overall win for our rhino populations.
With regards to demand of specific horn (eg. wet vs. dry), we would need greater research of the demand. South Africa has a stockpile of about 20 tons of rhino horn – this stockpile would be the ideal ‘tester’ to obtain this and other important data on the economic aspects of a potential legal trade in horn.
Who would set and control the sale value, or would it be conducted on a regular auction basis? How would one settle upon a figure? By basing it upon current illegal street value, or by forcing it right down? That would be in best interest of the fight against poaching, but how would it be in the best interest of the private farmer who would, (I assume), want to see the greatest return upon their investment?
Mostly answered in previous questions. If horn trade is legalized for the private sector and for government, the poachers will suffer. Game ranchers will receive a return on their investment and the poacher’s bottom line will be eroded.
What guarantees are there that such sales, (whether as a one off stockpile auction, or sustainable farming), will be properly audited and proceeds be directed to wildlife conservation? Would the same current problems of corruption etc not still be a factor?
Yes, as they always are and always will be in Africa. The legal trade of rhino horn does not guarantee an end to poaching or an end to corruption. It would be impossible to make any guarantees of this kind. However, it is not impossible to see that the benefits of legal trade in horn far outweigh the current prospects for rhinos, if the status quo is maintained.
It would be extremely important that the CSO be audited and monitored to ensure that any and all trade is ethical, responsible and fair. We also feel that there would be a necessity for a body (also subject to auditing and monitoring), consisting of primary stakeholders in rhino conservation and management, to ensure the effective and ethical management of rhino conservation practices and its compliance with RhoDIS.
We believe that this sales model would certainly reduce poaching levels drastically.
Supportive law enforcement would have to be rigorous and consistent.
If the trade is legalised, how much of a percentage do you expect the government to take, and to what ends would this income go?
Sales of horn should be proportionate to registered suppliers. As the government owns 75% of our rhino population, it would be fair to say that we expect them to take 75% of any income. Keep in mind that any private horn sales will be subject to a number of taxes, eg. VAT, Export.
There is a great deal of pressure on our national and provincial parks to become self-sustaining – this increased revenue would go a long way towards attaining these goals. Rhino security has also become an extremely expensive prospect and a thriving industry over the past 4 years and any income generated would keep our rhinos safer, not to mention the other species that occur in rhino habitat.
Why, if this decision on trade is so important, (from the viewpoint of those both for and against it), has the Govt application to CITES been delayed until 2016? How early after this decision, if approved, could trade commence?
Our government feels that insufficient data is available on market trends and sale aspects. Needless to say, many people are incensed over the delayed responses of government. We feel that this delay is going to cost us probably another 3 000 rhino lives over the next 3-4 years – an unnecessary cost and a tragic indictment against us as South Africans.
How will it affect pro trade private owners if the decision goes against them?
Many more of them will probably continue to disinvest in rhinos as it is simply becoming too risky and expensive to own them. Poaching levels will continue to soar and eventually, as the last refuge for rhinos dwindles along with our rhino populations, horn value will be so grossly inflated that people will be forced to get rid of it, whether through destruction or illegal means. The decisions against trade have not worked for rhino anywhere else in the world - in fact, they have led to near local extinction in many rhino range states. It is time for a different tactical approach.
The Pro-Trade lobby are calling for trade, at the very least, to be open in SA. In other words, SA horn may be traded within SA borders. How would this benefit SA farmers? Who is going to buy horn if they cannot then sell it outside of South Africa’s borders? Would horn not simply end up in the wrong hands and find its way out of SA as it does now, making the legal trade a market for illegal horn and the real profits be made smuggling it illegally?
This is an important point. Prior to the national moratorium, rhino poaching figures were minimal. Undoubtedly, any horn being sold internally was reaching the international consumer market and the only way it could have done this is illegally. The relevant point here is that our rhino populations were not threatened and being poached at unsustainable levels before the national moratorium was passed. Rhinos were not dying to provide horn, as they did not have to. Our rhino populations were healthy and growing. Black Market prices were relatively low as there was minimal risk in obtaining the horn and the supply wasn’t limited. By cutting off the legal supply, we have boosted the illegal supply and fueled the illegal trade.
How would sales actually work? What are you putting forward as a working model?
A series of auctions (perhaps one a year for the next five years) of rhino horn, using the current stockpiles of horn makes perfect sense to us for the following reasons:
1. We are currently losing almost 2 rhinos a day while SA and other range states have tons of horn in stockpiles. Every syndicate member that is arrested with rhino horn and every confiscated horn that gets added to these stockpiles spells death to yet another rhino. For every horn we are able to sell, we may just be saving the life of a rhino and this point must be emphasized to the authorities and the public.
2. One of the massive hurdles in the trade/no trade debate is the lack of accurate market figures. Many people who are opposed to trade claim that we will never be able to satisfy the demand for horn but this is something that we can never estimate until we have accurate and realistic market figures. These auctions, assuming they are carefully planned and managed with clear objectives and monitoring techniques in place, will give us the economic facts we need in terms of market structure.
3. These auctions will generate a desperately needed income injection for rhino management and protection, especially for our national parks, which are currently hardest hit by poachers.
4. If, after 5 years, poaching figures have not come down and the legal sales of horn have not eased the immense pressure that is currently on our rhino populations, we can simply stop the auctions and start focusing on a new strategy to save our rhinos. We, as South Africa, would have lost nothing at all, as the horns in stockpiles are currently worthless when in fact, they should be the currency for invaluable information-gathering and accurate data and research.
You say we should open trade for up to 5 years and if it does not stop poaching or at least make a big difference then trade can be stopped again. On what study or credible information do you base the fact that a legal trade will stop or reduce poaching? Secondly, knowing how long a decision like to legalise trade or not takes, how would one stop trade again if it has been shown not to work after 5 years?
We have a wealth of studies and information from conservation economists, wildlife ranching practices, government, educational institutions and individuals that we have based our opinions on. We encourage readers to join our mailing list for these sources and this information.
If legalization of trade in horn did not work for our rhinos, then we don’t know what will. Perhaps we would have to consider moving all of our rhinos into centralized and intensively protected areas, away from borders and we would have to protect them in these ‘fortresses’. This would be a sad day for our rhinos and yet another failure for humans.
Who and by what means can it be guaranteed that buyers in Vietnam / China would not stockpile horn at their end and sell it by trickling small amounts out gradually, thus keeping prices artificially inflated?
By ensuring that the trade is ethical, sustainable and regular and making sure that consumers know this. Free markets work, closed markets do not.
How do you think those who are currently dealing in and benefiting from poaching will react to trade being legalised?
I’m sure they will be terribly upset to know that their profit margins are taking drastic cuts. The small percentage of people who own rhinos and are benefiting through poaching will stop killing their rhinos and start breeding them. The legal market will undercut and out-supply the Black Market in a short and effective space of time.
What is your response to the argument that legal trade will open up a new market, therefore, increase demand, (as was the negative consequence of the last ivory stockpile auction), increase its value, and therefore run the risk or inciting a greater level of poaching than we are seeing now?
It is completely illogical that anything that can be physically bred, protected and conserved would run out. Rhino horn is a natural and sustainable resource and we have over 20 000 rhinos in the country, 25% of which are in the private sector.
Even if the current demand for rhino horn (based on poaching levels and horn seizures) increased four-fold, we would still be able to supply the market. Comparing sustainable rhino horn trade to isolated bulk ivory auctions is a non-sequitur. The ivory sales were disastrous for a number of reasons, not least of which was the 10-year moratorium imposed as a condition of these auctions – this forced a speculation reaction in consumer countries. African countries got less than 30% of the market value of ivory at the auctions due to inadequate planning and market research – a clear disaster that also encouraged buyer speculation. At all costs, these mistakes must be learned from and avoided in any rhino horn trade.
Unlike ivory, rhino horn is a product which is consumed – therefore demand is likely to grow to from an expanding middle class, especially as its use moves away from TCM uses. How can sustainable farming/legalised trade meet demand for rhino horn in the long term, if demand continues to rise to the point where supply simply cannot compete?
I think this growth in demand would take some time. With legalized trade will come increased incentives for rhino breeding operations. We have a vast amount of land available throughout rhino range states. The day we reach a point where demand outstrips supply will be the day that the rhino will be doomed anyway. With the status quo and current poaching levels, that day is approaching very fast for rhinos. By legalizing trade in horn, the worst we can do is buy our rhinos a substantial break from the current poaching levels and the best we can do is rescue the species.
Taking the trade argument one step further, why not breed rhino to sell to China and Vietnam so they can continue building their own sustainable farming facilities?
Under the current status, this may appear to make sense but if a free market existed, this would be unnecessary. Neither of these countries have a particularly positive history for their own natural resources – would we really want to sell them ours? Rhinos are one of Africa’s natural resources and the trade in their horn would have positive spinoffs for many species that live in rhino habitat, for our impoverished communities, for the area under natural habitat, for greater conservation measures, for the government, for the rhino owners and for the rhinos themselves. It would make no sense at all to sell this.
Looking at the lifespan of one rhino, how often would you harvest its horn, therefore, how often would you tranquilise it and what stress and negative effects would this cause the animal?
Rhino horn regrows at the rate of about 1kg per male and about 600g per female per year. Rhinos live for about 35-40 years so you would probably be able to harvest 8 – 10 horns in its lifetime or about 60kgs per rhino.
The tranquilising drugs and dehorning procedures are extremely safe when administered and performed by qualified veterinarians. Long term effects of these drugs used in darting a rhino approximately once every 2-3 years appear to be minimal, according to veterinary studies; however, more long-term research is needed to be sure. Rhinos undergo a small amount of stress at the actual darting but once they are tranquilised, the stress factor is non-existent. It does not hurt a rhino to dehorn it as horn is composed primarily of keratin, so the 20-minute procedure is similar to trimming a horse’s hoof.
Behaviourally, the effects are minimal, particularly on White rhinos and they will continue to survive normally. Dehorning rhinos also leads to far fewer fatal wounds in territorial disputes – another advantage of the procedure.
We administer a very small survival risk to our rhinos to remove a very large risk. As an analogy, I ask you: why would you have a colonoscopy? For your own good.
There is a relatively comprehensive study on dehorning, done for the EWT – again we encourage readers to contact us if they are interested in this material.
How will legalisation protect rhino in countries where ownership is not private?
State rhinos will benefit in the same way as those on private land. Sale of horns = greater revenue = better security options = conservation funds = land expansion = rhinos being worth more alive than dead = greater incentives to breed rhinos = more rhinos.
How will the State parks’ and publicly owned rhino benefit if the trade becomes legal?
As above.
Following on from this question, if you were able to sit at a Government round table, what would your proposals be to protect wild rhino from poaching?
We have sat at these tables and our proposals were the same: legalise trade in rhino horn to save our entire rhino population.
Dehorned rhino are being poached now, as the price of wet horn soars. How will trade legalisation help prevent such occurrences?
Only a very few dehorned rhino have been poached. At this stage, it is far more lucrative for poachers to find horned rhinos to poach as the rewards far outweigh the risks and because rhinos in our national parks are relatively easy targets. This is verified by a comparison of national park’s poaching figures (very high) vs. private sector poaching figures. Dehorning is not a solution to poaching, it is simply a deterrent. If it is not performed in conjunction with a strict and affective security program, it is pointless. As our horned rhinos are eradicated, more dehorned rhinos will be poached. Trade legalization will offer the consumer the option of buying legal, ethical, registered, sustainable horn with no risk as opposed to illegal, cruel, unsustainable horn with massive risks.
What impact do you think the legalising of trade in rhino horn may have on other species which are being heavily poached due to demand for body parts?
We hope that it will bring about an understanding that concepts of preservation are noble but unsustainable – Kenya’s wildlife disaster is a case in point. If we cannot find innovative ways to integrate humans and wildlife, we will fail the wildlife. Each of these conservation issues need to be scrutinized and analyzed individually to determine the best course of action. Rhinos are one of the luckier of these species in that they do not have to die to provide the product.
Does the fact that communities are disenfranchised from the country's wildlife contribute to rhino poaching? What about a model based upon CBNRM, (community-based natural resource management), in which such communities around South Africa become stake holders with the rhino as a flagship species?
We should move some rhino from our National Parks and put them in the custody of the communities and black emergent farmers. Game farmers and breeders should be encouraged to engage surrounding rural communities and teach them to conserve and breed with rhinos. If the communities are generating a substantial income from these rhinos they would literally guard them with their lives. It will change the general attitude towards poachers in the rest of the country and particularly around their own communal rhinos.
This will play a significant role in addressing two major conservation issues: poverty and habitat loss.
If we donated 4 800 rhino to the communities in this manner and they increased them by the same percentage that we have increased them for the last 50 years, we will have 29 000 rhinos owned by the communities in 25 years’ time.
In order for this model to be successful, the communities will have to benefit from it and fortunately the rhino has the appropriate reward.
As a simple model, if you distributed these rhinos to 120 communities on average they would get 40 rhinos each. Initially, they would probably get 160kgs of horn off their rhinos and thereafter 40kgs per year. At the prices currently being quoted by the media this would be an enormous income and poverty alleviator for these people. These communities would need about 600ha of land for 40 rhino.
How can the South African government do more to protect this iconic species in country, and what about the African Union? Why aren’t they doing more to protect the rhino across all remaining range states? What could they do which would make a visible difference? How is the government helping the private owner, no matter which side of the line they sit on?
The South African government can help by taking a wise stance on the trade issue and doing so boldly and with confidence, without being affected by the rest of the world’s views and perspectives. SA is the only country in the world that has managed to conserve over 20 000 rhinos and it is up to us to continue to do so. Following the examples of other range states would be about the worst thing our government can do. The African Union’s support would be appreciated in these endeavours. They are not doing more to protect rhinos in other range states because there is no incentive to do so. When we change this perspective, the trend will change too.
The government does not do anything to help the private sector. In fact, the private sector helps the government by paying taxes, levies and permitting fees and generating tourism.
What is your opinion of CITES: what power do they really wield? And in your opinion, is the CITES trade ban contributing to/fueling the poaching?
The role of CITES is a bureaucratic one, not a practical one. CITES is made up of 175 member parties and as a combined voice, they wield power. They do not make or take decisions on internal conservation trade issues, only on international ones.
We definitely believe that the ban on trade has fuelled poaching endeavours and here is our proof:
The ban on trade was implemented in 1977.
- When Black rhinos were listed as Appendix I animals in 1977, there were still more than 50 000 left. Today, there are about 3 800 left and they are critically endangered.
- The Northern white rhino, that number between 2 000 – 4 000 animals in the 70’s is extinct in the wild today, much like the Javan rhinoceros.
- In Swaziland, the "Rhino War" lasted from 1988 - 1992, during which time this country lost 80% of its rhino population to poachers.
- In Mozambique, the rhino is all but extinct.
- In 1992, Botswana had less than 20 White rhinos left and the Black rhino was locally extinct.
- In Tanzania, numbers of both species of rhino have declined drastically over the past 50 years. There were approximately 10 000 Black rhinos here in the 1960's and by 1984, there were only 3000. 6 years later, in 1990, there were less than 100 Black rhinos left in Tanzania.
- There were about 20 000 Black rhinos in Kenya in the 1960s. Today, there are about 700.
Rhino poaching figures in South Africa rarely reached double figures prior to 2008, but this is not because the trade ban was effective. This was because other African states were having their rhino populations decimated to feed the demand.
Why should SA continue donating or selling rhino to other range states, if their security is not guaranteed?
They shouldn’t. But banning trade in live rhinos will be yet another step in the wrong direction. At this point, live rhino sales are one of the very few ways that rhino owners and breeders can still generate an income. If we remove this option, we are only adding more fuel to the rhino’s pyre.
How are stockpiled horns managed? What happens to them once they have been removed from the rhino, or been retrieved from poachers/traffickers? When a horn is recovered from the latter, does it become property of the state, whether or not its origin can be traced?
Once removed, rhino horn goes directly to a secure location, generally a bank vault. Yes, seized horn becomes state evidence and property.
How are rhino horns treated against decay? I’ve heard it said that diesel is used to prevent infestation by beetles and other bugs – if true, such a stockpile sale would take place with all parties knowing the possible health risks of their consumption would it not?
We do not have much knowledge of diesel treatment although we have heard of this method being used many years ago too. Regarding toxicity, we would imagine that one would be able to detect diesel fumes in a horn and even if a diesel-treated horn were consumed, it would be in a miniscule and diluted quantity and probably harmless. However, we cannot verify or deny any of this. My horns are kept in insect-proof boxes in secure locations.
With regard to the public funding of Rhino NGOs, in your opinion, what is the best way for such orgs to use the money – raising awareness or directly assisting the fight on the ground? (Please explain with reasoning.) Indeed, do you feel that the plethora of NGOs are doing enough for the private owner, whether they be pro or anti trade?
We are not associated with or assisted by any rhino NGO’s so we cannot offer opinions on whether they do enough for private owners. As for whether they do enough for our rhinos in general, the answer is no. Escalating poaching figures verify this. The legitimate ones may provide some relief of the symptoms of the crisis but they do not help the cause. Until we can solve this crisis at root level (supply and demand), we will continue to inadequately treat the symptoms. Also of concern is that we currently have about 250 rhino NGO’s and periodically they are in the news for misuse of funds, fraud, etc. Many people, on all levels are riding on the back of the rhino crisis without providing any valuable contribution to the solution of the problem and in the worst cases, exploiting it.
As a businessman, how do you respond to those who argue that your main interest, first and foremost is profit, over wildlife conservation and that such conflict of interest negates the relevancy of your pro trade for conservation position?
If anyone’s passion can also offer a financial return, would it not be all the more successful and rewarding? Any legitimate conservationist knows that conservation needs to pay for itself and that notions of passive preservation and wild, open, untouched spaces are idealistic in today’s developing world, if the poaching scourge is not stemmed. If all conservationists were millionaires, the world would be a different place and a much happier one for our wildlife. I sincerely hope to make a healthy profit from my horn sales as this will enable me to further protect my rhinos; it will encourage many more people to breed and protect our rhinos and my vision of Africa having 100 000 wild, horned and safe rhinos again will be realized.
At this rate, with no specific policy in place, (and based on an average of 50 poachings per month), what is the future of both privately owned and wild rhino in South Africa?
Bleak.

Zululand Rhino Reserve
Zululand Rhino Reserve
The Zululand Rhino Reserve is a 23 000ha Big 5 reserve on the Western side of the N2 between the towns of Hluhluwe and Mkuze.
There are 3 water ways that wind their way through the reserve; the Msunduze River, Sekane River and Manyoni River. Traditionally the Msunduze Valley has always been suitable for wildlife and traditional Zulu (Nguni) cattle. It was a seasonal grazing area and traditional hunting area of the Zulu clans that lived away from the valley. Lack of water and disease (Malaria and Nagana (sleeping sickness)) precluded habituation. After the First World War the area was subdivided into small (uneconomical) ranching and cropping units. Gradually these were developed, boreholes drilled and later were amalgamated into larger cattle ranching units, and then into game ranches. The reserve comprises of 17 different landowners who dropped their fences to create the ZRR. Each landowner is a shareholder in the company which is managed by a central body.
The land owners are each responsible for their own property but the ZRR management team is responsible for the wildlife, habitat management, security, boundary fence maintenance and business component of the company. In 2005 the ZRR became the second Game Reserve to become part of the WWF / EKZNW Black Rhino Expansion Project with the release of a founder population of Black Rhino, and by 2006 the first calf had been born. In April of 2009 everyone’s efforts were finally rewarded when the reserve was officially proclaimed a Protected Area, it is classed as a Nature Reserve - the highest status within the KZN Biodiversity Stewardship Programme. The Black Rhino (Diceros bicornis minor) is just one of the many reasons why the ZRR was able to acquire this conservation status. Other species of significant importance in the reserve include Wild Dog (Lycaon pictus), Leopard (Panthera pardus) Brown Hyena (Hyaena brunnea), Suni (Neotragus moschatus), Lappetfaced Vulture (Torgos tracheliotos), White-backed Vulture (Gyps africanus), Whiteheaded Vulture (Trigonoceps occipitalis), Bateleur (Terathopius ecaudatus), Rock Python (Python sebae natalensis), Kudu Lilly (Pachypodium saundersii), Climbing Onion (Bowiea volubilis), Huernia histrix, to name a few. In the near future the ZRR will be starting projects to supplement some of the current animal species populations of Cheetah, Hippo, Bushbuck, Brown and Spotted Hyena.
There are a number of lodges within the ZRR that offer Game Drives and Walking Safaris. Guests can expect to see a large diversity of Fauna and Flora with over 450 birds, 70 mammals and almost 200 species of trees and shrubs occurring in the area. With prices that range from R670 to R1695 there is something to suit everyone’s budget.
Zululand Walking Safaris is the only company that offers guiding walking safaris to guests that are not staying in the Zululand Rhino Reserve and we pride ourselves in being able to offer guests a very unique African experience. Walking Safaris or Trails are between 2 hours and a few days long, with guests using all 5 of their senses to really experience the African Bush.

Spider & Scorpion Course 19th of August
A full day's course in arachnids will be presented by arachnologist Jonathan Leeming on Sunday 19th August at Bonamanzi.
Jonathan is one of South Africa’s foremost experts on scorpions and spiders and author of the book ‘Scorpions of South Africa.'
Also conducting 'Scorpions Adventures', Hoedspruit based Jonathan recently spend time in the area presenting courses and leading field trips, and got to know some of our local eight legged creepy crawlies.
Northern Natal offers a variety of habitats and a high arthropod diversity and is home to high population densities of spiders and scorpions. In some areas of KZN the scorpion population density can be as high as 3 scorpions per square meter!!
This course is ideal for anyone interested in spiders, scorpions, amblypygids and solifugids,
or for those who would like to learn from a leading authority. Everyone is welcome even if you can't tell the difference between a scorpion and a crab.
The course consists of lectures in the morning and hands on practical field work in the afternoon and provides the solid foundations for understanding and identifying Southern African spiders and scorpions.
Handling of spiders and scorpions is not compulsory but provides a very exiting hands on experience.
The course is endorsed by both F.G.A.S.A and the I.Z.S
Cost of the course is R945 per person and includes workbooks. For more information download the pdf brochure on https://dl.dropbox.com/u/25478279/BonamanziCourse_2012_small.pdf or visit Jonathan's website www.scorpions.co.za, or contact him directly Jonathan@scorpions.co.za

Elephants drunk from marula fruit?
Almost anyone who has read a travel brochure about Africa has heard of elephants getting drunk from the fruit of the marula tree.
The lore holds that elephants can get drunk by eating the fermented fruit rotting on the ground. Books have been written asserting the truth of the phenomenon, and eyewitness accounts of allegedly intoxicated pachyderms have even been made.
But a new study to be published in the March/April 2006 issue of the journal Physiological and Biochemical Zoology tells a very different story.
Steve Morris, a biologist at the University of Bristol in England and a co-author of the study, says anecdotes of elephants found drunk in the wild go back more than a century.
"There are travelers' tales from about 1839 reporting Zulu accounts that 'elephants gently warm their brains with fermented fruits,'" Morris said.
But there is nothing in the biology of either the African elephant or the marula fruit to support the stories, he asserts.
"People just want to believe in drunken elephants," Morris said.
Eating Rotten Fruit?
The marula tree, a member of the same family as the mango, grows widely in Africa. Its sweet, yellow fruit is used for making jam, wine, beer, and a liqueur called Amarula.
But the first flaw in the drunken-elephant theory is that it's unlikely that an elephant would eat the fruit if it were rotten, Morris says.
Elephants eat the fruit right off the tree, not when they're rotten on the ground, he explained.
"This a largely self-evident fact," he said, "since elephants will even push over trees to get the fruit off the tree, even when rotten fruit is on the ground."
Other experts add that if an elephant were to eat the fruit off the ground, it wouldn't wait for the fruit to ferment.
Michelle Gadd, an African wildlife specialist with the U.S. Fish and Wildlife Service, says that elephants and many other animals—including birds and monkeys—are too fond of marula fruit to let it rot.
"Animals flock, fly, or run to ripe marulas to take part in the gorging, leaving few fruits lying around long enough to ferment," she said.
"Elephants regularly visit and revisit the same marula trees, checking the fruits and the bark for palatability and devour the fruits when they are ripe."
Internal Fermenting?
If fermented fruit on the ground is out of the question, so too is the notion that the fruit could ferment in the stomach of elephants, the study authors say.
Believers of the drunken-elephant lore have often supported this theory of internal fermentation.
But food takes between 12 and 46 hours to pass through an elephant's digestive system, the authors point out, which is not enough time for the fruit to ferment.
Moreover, the authors write, "sugars within the diet are metabolized … to volatile fatty acids, making them unavailable to fermentation."
In other words, the sugars are turned into fat before they can ferment into alcohol.
It is conceivable, the authors concede, that some small amount of ethanol—also known as grain alcohol—could be produced in an elephant's digestive system, if its diet were rich enough in both yeast, which is necessary for fermentation, and fruit.
Even in the unlikely event that these things happened, it's still highly improbable that the food would produce enough alcohol to make an elephant drunk.
How Much to Get an Elephant Drunk?
This raises another question: Even if, under very peculiar circumstances, an elephant were exposed to alcohol, how much would it take to get it drunk?
Through calculations of body weight, elephant digestion rates, and other factors, the study authors conclude that it would take about a half gallon (1.9 liters) of ethanol to make an elephant tipsy.
Assuming that fermenting marula fruit would have an alcohol content of 7 percent, it would require 7.1 gallons (27 liters) of marula juice to come up with that half-gallon of alcohol, the scientists say.
Producing a liter of marula wine requires 200 fruits. So an elephant would have to ingest more than 1,400 well-fermented fruits to start to get drunk.
Even then the elephant would have to ingest the alcohol all at once, the authors note. Otherwise its effects would wear off as quickly as the alcohol was metabolized.
Robert Dudley, a biologist at the University of California, Berkeley who was not involved in the study, believes the authors have put to rest the lore of elephants getting drunk from marula fruit.
The study, he said, "establishes that elephants are unlikely to be inebriated but also that chronic low-level consumption [of alcohol] without overt behavioral effects is likely."
It may make for a good story and a durable myth, but the science suggests you're not likely to see a drunken elephant sitting under a marula tree.

FGASA KZN North exam workshop
Dear FGASA members,
The KZN North Working Group wishes everyone writing the national exam the 7th of July good luck! For the people writing in Hluhluwe, we do offer an 'exam workshop' for learners writing the FGASA Level 1 exam, where you can come and ask questions about the topics you still might struggle with. The KZN North facilitators will then try to help you by answering your questions and explaining things where necessary, hopefully helping you passing your exam. This service is for free. These workshops will be held Bhejane Nature Training on the 5th of July from 6 PM till 9 PM.
Should you wish to make use of this service, please ensure that you make a reservation with the facilitators, to avoid finding them too busy with other students, and to avoid them sitting there for nothing. For the exam workshops, please text Christa Panos on 083-7263826 or email her on dpanos@tiscali.co.za. Make sure you mention your name, and the time you wish to meet. Also ensure that you actually go to the workshop on the specified time, and should you not be able to, make sure you cancel your appointment with your facilitator in time.
Once again: Make a reservation with your facilitator! No reservation might mean the facilitator has no time for you that evening. And: If you have a reservation, make sure you come: No show (without cancellation) is no more future exam workshops for you... And please come prepared with your questions. If you have no questions, your facilitator unfortunately cannot help you.
We hope this free service will ensure a higher pass rate amongst learners in this region.
Sincerely yours,
The FGASA KZN North Working Group
