The world’s largest plant-eating animals like elephants and rhinoceroses are facing dramatic population losses due to poaching and resource destruction, with 60% of large herbivores threatened by extinction, according to a new study.
Grass-grazing giants like elephants, hippopotamuses and black rhinoceroses only occupy a tiny fraction of their historical ranges, according to the study in Science Advances, and the loss of herbivores over 100kg (220lb) is likely result in “enormous ecological and social costs.”
The loss of large herbivores has been endemic in Africa for years, but the study sheds new light on the widespread loss of large animals due to over hunting for meat—some one billion people rely on wild meat for subsistence.
Hunting and land-use changes have a devastating effect on those species, with habitat loss due to deforestation and meat hunting having a particularly negative effect. The number of forest elephants in central Africa declined by 62% between 2002 and 2011, and some 100,000 elephants were poached between 2010 and 2012.

The Samburu live in the northern highlands of Kenya; they are the country’s largest land occupiers and yet number few in a country of tens of millions. Fierce pastoralists, they saw no value in having wildlife on their lands because they believed it belonged to the government and was, therefore, of no benefit to them; cattle were allowed to graze everywhere, seriously degrading the grasslands. Under the stewardship of the Northern Rangelands Trust, the Samburu are learning to regenerate their lands and live alongside the wildlife.David Chancellor —INSTITUTEAt dawn, Samburu Moran warriors take a camel to slaughter.David Chancellor —INSTITUTEPrior to attending Imuget le nkarna (a celebration of 10 years as a warrior) Samburu Moran apply red ochre to their bodies.

A Samburu is a warrior for 13 years, during which time he lives completely in the bush with his cattle, drinking blood from the cows, milk, and occasionally water, and eating meat.David Chancellor —INSTITUTETraditionally a moran carries little more than a spear, a knife and a plastic five-litre oil container, which is used as a container for water, milk, and as a pillow to keep his headdress off the ground while sleeping. Now with the huge influx of weapons from neighboring Somalia they will often carry an illegal G3 rifle or similar, with which they will protect their cattle from raiders, and raid other tribes for their cattle.David Chancellor —INSTITUTESamburu moran take the meat that has been cut from slaughtered cows and hang it over a central tree. It will be cooked over open fires and placed on the ground under the same tree, from where it will be eaten by the warriors. This is one of the few occasions that the Moran will get to feast on meat during their time as warriors.
From this point on (10 years as warriors), they are permitted to take wives. The Samburu have an ancient connection to elephants: they require elephant dung to marry and consider them sacred. Any Samburu that kills an elephant brings a curse (called "alanna") upon his family. Despite this, and with the incredible amount of money being offered, some Moran are now becoming poachers on lands where elephants would previously have been protected by tradition alone.David Chancellor —INSTITUTEA leopard caught and killed in a poachers' snare is removed by conservancy rangers.David Chancellor —INSTITUTEA veterinarian treats a lioness for an eye infection, Lewa Conservancy, Northern Kenya.
The dual use of wildlife and livestock by communities in these remote areas of northern Kenya spreads the economic and financial risk, reduces vulnerability to droughts, and increases food security, it does however also increase the possibility of human-wildlife conflict which results in the necessity to also manage the wildlife itself. Wildlife can be used to generate the capital needed to help communities improve their welfare and bring peace, giving them a clear financial stake in preserving wildlife rather than killing it.David Chancellor —INSTITUTECall sign 9.2, Isiolo County, northern Kenya.
‘9.2’ is a mobile multi-ethnic anti poaching unit who can respond quickly and effectively to any given situation, not just poaching, across all of the Northern Rangelands Community Conservancies, without fear of tribal conflict. They live in the bush for 26 days of each month, returning to base to rest and re-equip for the remaining four days of each month.

The irony is that as grazing management programs become more successful farmers move into areas previously only inhabited by wildlife, which results in an increase in human wildlife conflict. Here a farmer walking home in the evening was chased by an elephant, gored and trampled to death. The community demanded retribution. The elephant was hunted down by Kenya Wildlife services, shot, and its tusks removed and placed in the same safe store in Nairobi as those from poachers.David Chancellor —INSTITUTEA poacher is interrogated by members of KWS and the community conservancy anti poaching unit ‘9.2’.

Poaching continues to harm large grazers, particularly rhinos. “This slaughter is driven by the high retail price of rhinoceros horn, which exceeds, per unit weight, that of gold, diamonds, or cocaine,” the study said.
Slowing deforestation and over-hunting, and halting poaching, will be crucial to ensure the large grazers don’t go extinct. “Solving the current crisis associated with poaching for meat and body parts is an essential step, although one that is extremely challenging,” the authors write.
