7 northern white rhino left
worldwide
September 22 2011 at 06:02pm
There are only 7 northern white rhino left in the world and
conservationists are worried about the future reproduction of
the world's rarest large mammal.
The reason for the decline in the population is attributed to
hunting, poaching, and loss of habitat.
The white rhino can still be seen in the Kruger National Park.
Until 2009, the last eight northern white rhinos lived in two
zoos in Europe and the USA. On December 20, 2009, four of the
last eight were moved from Dvur Králové Zoo in the Czech
Republic to Ol Pejeta Conservancy in Laikipia, Kenya.
While in captivity, the survival rate of northern white rhinos
are good, but reproduction rates are extremely low. The four
rhinos were relocated back into the wild in hope of bringing
about successful mating. Many said that the operation would put
the animals at risk because they had spent so long in protected
conditions and they would not be used to the harsh African
environment.
Members of the European Association of Zoos and Aquaria stated
that they didn't think that “any significant conservation
benefits will happen,” from the placement of the rhino back in
the wild and in March 2011, they were almost correct. Just over
15 months of being released into the central Kenyan highlands
and the northern white rhino's began 'mating' activities. This
behavioral change served to confirm that the four rhino had shed
their non-procreational coexistence that they adopted while
living in captivity and had now returned to the way nature
intended it. Although the rhinos have been mating since in
Africa, there have not been any offspring which have resulted
from intercourse.
With reproduction of northern white rhinos coming to a halt,
inter-crossing of the northern and southern species is planned
by conservationists in order to ensure that the genes of the
northern white rhino do not die with the last of their species.
However, with recent technology, it seems that all hope is not
dead in losing the rare strain of the rhino's gene. With the use
of stem cell development it may be possible to produce the
northern white rhino from a test tube.
Director of Genetics at San Diego Zoo's Institute for
Conservation Research, Dr. Oliver Ryder says: “The greatest
contribution this technology might make is to prevent extinction
by using stem cells to assist with rescuing the genetic
variation in increasing the reproduction of a critically
endangered species.”
The following organisations have invested time, money, effort
and have proved highly dedicated to restoring the northern white
rhino:
Dvur Králové Zoo
Kenya Wildlife Service
Fauna & flora International
Ol Pejeta Conservancy
Back to Africa
Lewa Wildlife Conservancy
The Nature Conservancy
It seems that a combination of conservation effort,
anti-poaching legislation and scientific brilliance, the world
will never have to lose one of its precious species' again.
Quagga, we miss you.
