Western Black Rhinos and other subspecies were conserved in National Conservative parks and live species are still there. This experiment failed due to corruption. It demanded large amount of money, and the risk of failure was very high. In 1999 WWF published a report called “African Rhino: Status Survey and Conservation Action Plan.” This report recommended that all surviving specimens of the Western Black Rhino should be captured and placed in a specific region of modern Cameroon, in order to facilitate monitoring and reduce the attack rates of poachers. Some attempts were successful, but most experiments failed due to different reasons, including stress and reduced time in the wild. Rhino sperm was conserved in order to artificially fertilize females to produce offspring. There were many attempts to revive Western Black and Northern White. The teams had concluded that the rhino was extinct approximately five years before it was officially declared so by the IUCN. For this experiment, 2500 km of patrol effort resulted in no sign of rhino presence over the course of six months. In 2006, for six months, the NGO Symbiose and veterinarians Isabelle and Jean-François Lagrot with their local teams examined the common roaming ground of Diceros bicornis longipes in the northern province of Cameroon to assess the status of the last population of the western black rhino subspecies. The sub-species was declared officially extinct in 2011, with its last sighting reported in 2006 in Cameroon’s Northern Province. Widespread poaching is concluded to be partly responsible for bringing the species close to extinction, along with farmers killing rhinos to defend their crops in areas close to rhino territories, and trophy hunting.īy 1995 the number of western black rhinos had dropped to 2,500 individuals. There was a 96% population decline in black rhinos, including the western black rhino, between 19. For much of the 1900s, its population was the highest out of all the rhino species at almost 850,000 individuals. The western black rhino emerged about 7 to 8 million years ago. While it was believed that around thirty still existed in 2004, this was later found to be based upon falsified data. In 2001, this number dwindled to only five. No animals are known to be held in captivity, however it was believed in 1988 that approximately 20–30 were being kept for breeding purposes. Poaching continued and by 2000 only an estimated 10 survived. By 1980 the population was in the hundreds. As protection efforts declined over the years, so did the number of western black rhinos. The western black rhinoceros was heavily hunted in the beginning of the 20th century, but the population rose in the 1930s after preservation actions were taken. However, this belief has no grounding in scientific fact. Like most black rhinos, they are believed to have been nearsighted and would often rely on local birds, such as the red-billed oxpecker, to help them detect incoming threats. Many people believe their horns held medicinal value, which led to heavy poaching. During the hottest parts of the day, they slept or wallowed. They inhabited much of sub-Saharan Africa. During the morning or evening, they would browse for food. Like all Black Rhinos, they were browsers, and their common diet included leafy plants and shoots around their habitat. The western black rhinoceros is one of three subspecies of the black rhinoceros to become extinct in historical times, the other two being the southern black rhinoceros and the north-eastern black rhinoceros. The population was first discovered in Southwest Chad, Central African Republic (CAR), North Cameroon, and Northeast Nigeria. Other distinct features of the western black rhino included the square based horn, first mandibular premolar retained in the adults, simple formed crochet of the maxillary premolar, and premolars commonly possessed crista. This refers to the species’ long distal limb segment, one of many special characteristics of the species. The word “ longipes” is of Latin origin, combining longus (“far, long”) and pēs (“foot”). This subspecies was named Diceros bicornis longipes by Ludwig Zukowsky in 1949. The western black rhinoceros resided primarily in Cameroon, but surveys since 2006 have failed to locate any individuals. The western black rhinoceros ( Diceros bicornis longipes) or West African black rhinoceros was a subspecies of the black rhinoceros, declared extinct by the IUCN in 2011. The western black rhinoceros was believed to have been genetically different from other rhino subspecies. It was once widespread in the savanna of sub-Saharan Africa, but its numbers declined due to poaching.
