Re: Rhino Poaching 2013
A copy of my post today on the other side.
RE: White Rhino population growth (or not).
Upon reading and re-reading certain documents I am confused on some points surrounding the population growth rate of white rhino in KNP.
In Ferreira et al 2012
http://www.plosone.org/article/info%3Ad ... ne.0045989
it is stated that 2010 population estimate is 10621 white rhino in KNP.
In this currrent SANParks document:
http://www.sanparks.org/assets/docs/abo ... 7-2018.pdf
it is stated that annual average white rhino 'birth/growth rate' is 2%.
This is problematic. Firstly because in ecology birth rate and population growth rate are two different things. Birth rate is just that. Growth rate accounts for birth rate less morbidity. It is also problematic as it is significantly less than growth rates that have been widely quoted by Dr Mabunda and others over the last 2 years.
Can Sanparks clarify if the 2% growth rate is correct and if it accounts for management removals in addition to natural deaths?
This is important in light of the fact that: In the above published paper by Dr. Ferreira et al. it is stated that management removals determined by models around 'impeded ecological processes' are 4.4% of standing population at any time.
How many, if any, individuals have been removed for management purposes in 2011 and 2012?
What is the ongoing scientific assessment method used for managers to determine how many animals of which sex and age are removed at any time in a particular area?
In the Sanparks document referenced above it states a goal of keeping the incidence of poaching rates below the growth rate of white rhino.
Given that over 800 white rhino have been poached in KNP (that we know of) from 2011 to present then we are already over 400 animals in deficit over that time frame using Sanparks quoted growth rate.

Re: How many rhino do we really have?
mith, well done!
The thing is, no accurate estimates regarding birthrate/population increase can even be considered without a full aerial census of white rhino in Kruger. In fact, if it incorporated photographs, age/calf/herd/bull components could be there for all to see, not perfect, but at least at least giving a clearer picture!
This was meant to be done last year...either they did it and came up with a shocking "being brought down to earth" experience, or they didn't.
Either way, not good enough.

More rhinos being poached than are born every year
More rhinos being poached than are born every year
April 29 2013 at 10:59am
By DAILY NEWS CORRESPONDENT
Former Kruger National Park director Dr Salomon Joubert says the authorities will not win the war against rhino poaching.
Speaking during the launch of his book, Kruger National Park: A History, in Mbombela (Nelspruit), he said the number of rhinos being poached was surpassing the number being born annually.
“The white rhino population has historically enjoyed a 5-8 percent increase annually, but the mortality rate is now surpassing this, placing the population in very real danger,” said Joubert, who lived in the park for 40 years and served as director from 1986 to 1994.
“Despite the huge outcry against it, rhino poaching will never stop. This is a huge problem, and I suspect that the number of issues that need to be addressed are far too much for the practice to be stamped out completely.”
According to the latest figures released by the department of environmental affairs, 249 rhinos have been poached in South Africa this year. Some experts predict this number could reach close to 1 000 by the end of the year.
In 2010, a total of 333 rhinos were killed in South Africa, 405 in 2011, and 633 last year.
Rise
It is believed that the exponential rise in rhino poaching has been fuelled by rocketing demand in Asia and the emergence of highly organised crime syndicates operating in South Africa and Mozambique.
Joubert said corruption within the government was also a major factor.
“People are corruptible. Not only do the financial rewards appeal to the desperate souls who are recruited to do the dirty work, but also to people throughout the ranks. This includes officials within Kruger National Park and those in government, and is symptomatic of a large management problem,” he said.
“Discipline and passion for conservation are waning.”
Joubert said South Africa was not doing enough to help address the problem in Mozambique. “South Africa is not intervening. At the moment we do not have control over the assets that are our rhinos. So until we have organised ourselves and secured our assets, poaching will continue.”
It has also been reported that poachers have wiped out the entire rhino population on the Mozambican side of the Great Limpopo Transfrontier Park.
The transfrontier park includes Kruger, Mozambique’s Limpopo National Park and Gonarezhou National Park in Zimbabwe.
During a recent media tour, Kruger Park’s head of conservation, Dr Freek Venter, said Mozambican authorities had different laws regarding rhino poaching and that the stiff sentences given to poachers in South Africa were not applicable in Mozambique.
“The Mozambican authorities are not coming to the party. They don’t take the issue as seriously as we do and they do not have nearly enough resources to do anything about it,” said Venter. – African Eye News Service

As the measures taken against poachers in the worst-hit area of South Africa – the Kruger National Park – take on the trappings of an antiinsurgency operation, the toll taken on rhinos continues to rise. The figures speak for themselves: in 2010 146 Kruger rhinos were listed as killed. In 2011 it was 252 and last year the toll soared to 425. So far this year 180 rhinos are known to have been killed in the reserve. In fact the toll is even worse, as an extraordinary series in The Star by reporter Shaun Smillie and photographer Chris Collingridge has shown.
Our team gained access to Mozambican “poaching villages”, where comparative wealth from the proceeds of rhino poaching is conspicuous. Poachers are feted, as are pirates in the towns along the coast of Somalia established as a result of ship hijacking. And our team discovered the death toll is even higher than the official statistics, which do not take into account the rhinos which stray across into Mozambican territory, never to be seen alive again. Mozambique is clearly culpable of either not have the will to curb poaching, or of deliberately turning a blind eye.
Much of the rhino horn hacked off in the Kruger or neighbouring Mozambican territories ends up in Vietnam, where it is prized as a treatment for a variety of ailments. Curbing the incursions of Mozambican poachers, and reducing the appetite in Vietnam would do much to address South Africa’s rhino poaching crisis.

Re: How many rhino do we really have?
Another estimate... 
With between 8,000 and 10,000 white rhinos and about a thousand black rhinos, Kruger National Park is home to the majority

Re: How many rhino do we really have?
Mabunda made a statement a while back saying that poaching out numbered the birth rate. Some mathematician should work the numbers with those parameters and see what number we come up with for population. And that's from the horses mouth.
Man was placed in charge and given the duty of caring for all creation, are we doing it?

Sometimes it’s not until you don’t see what you want to see, that you truly open your eyes.
