Iberian lynx conservation and white rhino
There have been several reports in the scientific literature and on websites (I first saw one by Rebecca Morelle on the BBC site) about the dire situation facing one of the world’s most endangered cats. This is the Iberian lynx, that lives in Spain and has been under intense pressure from farmers and the general impact of humans for a long time. This beautiful cat is about the size of a cocker spaniel and has the ear tufts of the caracal or African lynx.
I found this picture (one of many) on this site through Google.
My only picture of a similar sized cat is of Africa’s serval, which has longer legs, but the same sort of body size. This one was taken in Kenya’s Meru National Park in the early 1970s.
There are thought to be only about 250 Iberian lynx left in the wild and there are those who have suggested that this puts them at risk because of low genetic diversity and inbreeding. The story is typical of the roller coaster for many species of wildlife. In the 1960s there were an estimated 3000 of the cats, but by 2005 the numbers were down to about 150. One major factor in the decline has been the reduction of the main food source, the rabbit. A successful and active captive breeding program has brought them back up to today’s numbers, but they are now only found in two isolated pockets in the south of Spain.
However, a recent report on the BBC website cites the authors of a scientific article by Dr. Love Dalen and others in the journal Molecular Ecology which suggests that the cat’s survival may not be doomed by its tiny population size.
The research suggests that the lynx has had little genetic variability over the last 50,000 years, and this has not hampered its long-term survival. The authors go further and imply that the information should offer hope to conservationists who are trying to reverse what seems to be a path to extinction.
Dr. Dalen, from the Swedish Museum of Natural History, is quoted as saying that "This indicates that some species can do fairly well at low population sizes, even for a very long period of time."
While most geneticists argue that there is a vital place for the use of genetic profiling in the conservation management of wild species there are examples of very successful recovery of almost terminal situations when genetic diversity has been severely limited.
As I wrote in my book The Trouble With Lions:
This pair of white rhino came to Meru in the late 1960s fror what was euphemitically called "Lesotho" (this was the days of apartheid and no credit could be given to South Africa in Kenya).
Let’s hope that with a population of 250 and a long history of limited genetic diversity, that the Iberian lynx can make a comeback like the southern white rhino has done.

As I wrote in my book The Trouble With Lions:
“The white rhino qualifies as one the really impressive examples of conservation in action. The southern race, which once occupied an area in parts of what are now South Africa, Zimbabwe, Zambia, Angola and Botswana, had all but died out by the year 1900.
A 1904 estimate had only 10 animals left in the country, all of them in the Umfulozi area of Zululand. Mainly through the efforts of one man, B. Vaughan-Kirby, who was the first game conservator in that part of the country, the species was brought back from the brink. In 1916 he reported 20 animals alive.
From that nadir the numbers climbed slowly to something short of five hundred when in 1952 Ian Player, oldest brother of champion golfer Gary, got involved in the very earliest translocation efforts and movement of the animals to many parts of Africa, and indeed to zoos overseas.
Between 1961 and 1972 white rhino had been moved to an impressive 38 new locations in South Africa and eight other African countries, including Kenya, where they went to Meru National Park and became my patients when I lived in the area for ten years. Over and above these destinations rhino also moved to 17 different countries, including Canada, the UK, and the USA.”
This pair of white rhino came to Meru in the late 1960s fror what was euphemitically called "Lesotho" (this was the days of apartheid and no credit could be given to South Africa in Kenya).
Let’s hope that with a population of 250 and a long history of limited genetic diversity, that the Iberian lynx can make a comeback like the southern white rhino has done.

Northern White Rhino – a last ditch try.
Good news, or a desperate move? That is the question that we can surely ask about the move of four of the world’s rarest mammals to Kenya from the Czech Republic. The answer is both.
The January-March issue of Swara, the Nairobi-published magazine arm of the East African Wildlife Society that bills itself as “The Voice of Conservation in East Africa” has two stories about the Northern White Rhino. One of these is by Kes Hillman, who, with her husband spent 22 years in Garamba National Park in what is now the Democratic Republic of Congo working on a variety of conservation issues, with a huge focus on the few remaining white rhino there, the last place on earth where they were known to exist.
I have no pictures of this race of rhino, but they look very much like the Southern race, with which I have had a fair amount of experience. Here is a picture taken in Kenya’s Nakuru National Park.While the article implies that the poaching of rhino in the region was worst from the 1960s, rhino poaching in Africa has a much longer history than that. In the very early 20th century armed gangs were sent out by colonial Europeans to shoot as many rhino as possible, simply to harvest horns for the dagger handle market in Yemen or the oriental medicine trade. By the1960s there were thought to be about 1300 animals in Garamba. Then came civil wars in Congo and the Amin regime in neighbouring Uganda which wiped out all the rhino, both black and white, in that country. When Douglas Adams, he of the five volumes in the trilogy The Hitchhiker’s Guide To The Galaxy visited Garamba the 1980s there were 22 northerns left. In 2008 when The Trouble With Lions was published, the number was down to three. In her article, titled “Could Ol Pejeta Be A New Start For the World’s Rarest? Kes Hillman tells of the inevitable end of that remnant.
The other article by Berry White is titled World’s Rarest Mammals Fly To Sanctuary In Kenya. In it she recounts how four white rhino were moved from a wintery, snow covered Dvur Kralove zoo to the Ol Pejeta Conservancy near my old home town under the shadow of Mount Kenya. In a well coordinated move that involved training of the rhino, specially designed crates, trucking, aircraft and a great deal of TLC, four animals, a female named Najin and her nine-year old calf Fatu, together with males Sudan and Suni made the journey. Naturally the Ol Pejeta’s Conservancy’s web site carries the story and gives more details.
This is really the last chance for this species of rhino. From the thousands that ranged across northern Africa in the days when the only records were in cave paintings, to the demise of all wild ones anywhere, we are left with eight captive ones, four of which are either too old or uninterested in breeding and live in two zoos. Will Najin or Fatu be the mothers of a new generation? Let’s hope we see a photo like this one (a Southern) in a forthcoming issue of Swara or on the Ol Pejeta Conservancy web site.

White Rhino Rescue
Linkhttp://www.wildlifeextra.com/go/news/pejeta-rhino.html#cr
In the book Last Chance To See written by the late Douglas Adams (he of the five books in the trilogy The Hitchhikers Guide To The Galaxy) and co-authored by Mark Cawardine, Adams described his visit in 1980 to the last refuge of the Northern White Rhino in what is now the Democratic Republic of Congo. At that time there may have been two dozen of the creatures left after a century of relentless slaughter, aka poaching. So relentless in fact that early in the 20th century the French organized and armed gangs of poachers for the express purpose of collecting rhino horn for sale. Then came the terrible times of Idi Amin in Uganda, and the end of all rhinos in that country.
This picture was taken in Kenya in the 1971 and shows Southern White Rhinos with their guard, but if I had not told you that this was the Southern, as opposed to the Northern, there is no way that you would have known - any more than I would if I had not been told. They look the same.
Four years ago, when I was in Kenya on a visit to my old stamping grounds around the town of Nanyuki, nestled on the western slopes of Mount Kenya, there was serious discussion of the possibility of bringing the last remnants (now only three or four animals) of the DRC group of rhinos to the Ol Pejeta Conservancy, where this picture was taken. That effort foundered on the rocks of local politics in the DRC’s Garamba National Park where the rhino hung on under some measure of protection. There was one glimmer, a faint one, in that seven individuals of this now critically endangered rhino had been taken to the Czech Republic and kept at the Dvür Krålové zoo. In ten years only one calf, a female, was born. There were three more in San Diego, but they were not breeding at all. In 2009 there are now only eight northern white rhino in existence.
Now comes the latest, and probably last attempt to save the remnants. As reported on the BBC web siteof 20th Nov under the banner headline
Czech zoo sends rare Northern White rhinos to Kenya
The translocation is not without is detractors, but Rob Brett, who is a member of the IUCN rhino specialist group is quoted as saying
"Moving them now is a last-bid effort to save them and their gene pool from total extinction."
More details emerge in another posting and it is here where one learns about the team of folks who have been involved in this exercise, and perhaps why some folks are concerned. These concerns stem mainly from the fact that the Northerns are likely to breed with the Southerns that are already at the conservancy (if they breed at all). Of course their gene pool would immediately be diluted, but the prevailing view seems to be that the genes would be lost completely if no efforts were made.
Of course the hope is that the return of the two males and two females to a more natural habitat, and relative freedom of thousands of hectares of bush, will turn on their reproductive juices. It seems a faint hope until one remembers that the thousands of Southern White Rhinos scattered in parks and zoos around the world are all descendants of about ten animals left alive in South Africa in 1904.
This animal was one of my patients in one of those refuges, Meru National Park in Kenya.You can find more about this remarkable recovery, and about the long and ugly history of rhino slaughter and why people do it, inThe Trouble With Lions.

Rhino Conservation and the probable disappearance of one race
It looks as if the planet’s last four wild Northern White Rhinos, which lived in the Garamba National park in the DRC have gone. As reported by Reuters in an article of June 16th Martin Brooks, head of the African Rhino Specialist Group, has stated that recent fieldwork has failed to find the animals. A new, and intensive, survey is planned under the direction of the African Parks Foundation, but it would seem to me that they have little chance of finding anything.
Northern White Rhinos do not look any different than their cousins of the Southern race, and it is now these that have been translocated to Uganda, to the Ziwa Rhino Sanctuary, where I have taken students,
and in 1966 were taken to Meru National Park, in Kenya, where I later had to do some medical interventions.
which I have documented in Wrestling With Rhinos and in The Trouble With Lions.
If the colours and picture quality of the animal with the big sore on its side look a bit dodgy, you may be interested to know that the photo comes from an old Super8 movie taken in the early 1970s. Super8 is incredibly small (8mm) and only technical wizardry has allowed us to use this picture.
As those who follow rhino issues closely know only too well, the pressure on them is unrelenting. If their horns are not being sold into Yemen to make dagger handles, they go to the Far East for use in traditional medicine.
It hardly matters who did the killing. In a country where war has been the norm for years and years it could be remnant armed militias like the ones who killed hundreds of hippo and have now started to take out elephants, (the war is supposed to be over) or even heavily-armed guerrillas from northern Uganda's Lord's Resistance Army, led by Joseph Kony , he of the bestial child abduction and slavery group who operate in the region. Either type of group would be hungry for the money that they could raise through the sales of rhino horn.
When I was in Kenya in 2006 there was a strong feeling that those four rhinos might find a home at the Ol Pejeta Conservancy, where they would have been relatively safe, as the place is heavily guarded. As there are no white rhino of the southern race inside the fence there would have been no risk of cross-breeding. The scheme seemed to be well ahead, and some of the logistics were being worked out. Then it all came to a halt. I am not sure why, but one reason given us was that locals in the DRC had objected. A sad end.
