The battle to save Africa's endangered mountain gorillas
Civil war, deforestation, disease and poaching have driven the mighty mountain gorilla to the brink of extinction. Conservation efforts have helped boost population numbers, but humans are still their greatest threat.
"Are you ready?" the guide asks. He is wearing a green army uniform and heavy black boots. "We could spot one within the hour, but there's always a chance that we'll have to trudge through rainforest all day," he warns.
The tourists in safari hats gather around him and listen attentively, clutching heavy cameras around their necks. They've paid $1,500 (1,277 euros) for this unique experience. After listening to the guide's instructions, they set off into the rainforest with two armed rangers and a several porters in tow.

Threatened with extinction
It is 8 a.m. and we are at the headquarters of the Volcanoes National Parkin north-western Rwanda, the starting point for gorilla trekking tours. On the horizon, steep, rocky volcanoes tower over green plantations and quiet villages.
The park is situated between the Virunga National Park in the Democratic Republic Congo and the Mgahinga Gorilla National Park in Uganda. Together with Uganda's Bwindi Impenetrable Forest, these parks constitute the last remaining mountain gorilla habitats in the world.
Mountain gorillas have been struggling for decades. Their homes have been destroyed by civil war, deforestation and agriculture, and as a result their population has dwindled. Gorilla trophies have long been popular among poachers and their rare meat fetches a high price on the black market. Researchers say that, in the late 1970s, there were only around 250 mountain gorillas left in the wild. The species was thought to be headed for extinction.
Gorilla population rebounds
Many attribute the gorillas' comeback to American biologist Dian Fossey, whose story was recounted in the Hollywood film Gorillas in the Mist. From the late 60s until she was murdered in 1985, the scientist devoted her life to saving mountain gorillas in East Africa.
Dian Fossey conducted ground-breaking research on great apes
"Without her, it is very likely that the mountain gorillas would have disappeared completely," says Veronica Vecellio, program manager at the Dian Fossey Gorilla Fund, which is charged with continuing Fossey's legacy.
The research institute is in Musanze, about a 20 minute drive from the Volcanoes National Park. The entire town has caught gorilla fever. There are hotels with names like Gorilla View Lodge and Villa Gorillaand there seems to be a gorilla statue at every turn.
Thanks to the increase in public awareness, local communities and international organizations have joined forces to support the gorilla population.
"Some groups are being visited by our researchers every day. We observe their behavior, health, location and sexual reproduction and document the lifecycle of every individual," explains Vecellio.
According the most recent gorilla census in 2010-2011, there are now about 880 mountain gorillas living in the wild — a major victory for the conservationists.

The human threat
Although humans have been credited with bringing the mountain gorilla back from the brink, they also pose the greatest threat to their survival.
The World Wildlife Fund says frequent interaction between gorilla groups and humans means gorillas are at risk of contracting human diseases. Climate change and habitat destruction are also persistent threats.
Prosper Uwingeli, manager of the Volcanoes National Park, is responsible for minimizing human impact in and around the park.
"It's important to get the local population engaged in our work," he says. "People need to understand the importance of conservation and how, by saving the gorillas, they are also saving themselves."
Partnering with organizations like the Dian Fossey Gorilla Fund, Uwingeli and his team educate locals on potentially gorilla-harming practices, such as making fires to fumigate beehives or placing snares for other animals which could inadvertently trap a gorilla. They also teach villagers to build houses without bamboo — an important food source for gorillas.

Since many villagers are poor and depend on the park's natural resources to earn a living, the park also offers them alternative sources of income. "The men can start working as rangers or porters, and the women sell baskets or souvenirs to tourists," Uwingeli says.
In the surrounding areas, tracts of land have been converted into tea plantations where people can work at a safe distance to the gorillas. "These plantations also serve as buffer zones between the villages and the gorillas' habitat," Uwingeli explains. "Gorillas don't like tea, so we hope the plantations will keep them far away from the villages."
A growing interest in the magestic creatures has helped boost conservation efforts. Still, Uwingeli says, it's important to keep the number of visitors under control.

"We adhere to the principles of 'ecotourism,' a model that respects both nature and the local population," he says. "Tourism generates money, which is good for the gorillas, but there has got to be a balance."
The park only grants eight gorilla permits per day. Tourists can spend a maximum of one hour with a designated group of gorillas — usually a group that is already accustomed to human contact. And all visitors must maintain a distance of 7 meters (22 feet) at all times.
"This way, we give the gorillas enough space and limit the chance of humans transmitting diseases," Uwingeli says.
Double the cost
Earlier this year, the Rwandan government doubled the price of gorilla-trekking permits from $750 to $1,500 per person. According to Uwingeli, this choice illustrates Rwanda's attitude towards tourism: "Higher prices mean fewer tourists, but we still earn more money. This reduces pressure on the gorillas, giving us more to spend on conservation, research and the local population."

The higher price tag also means that tourism profits shared with the local community will increase by 5 to 10 per cent.
But the government's decision came as an unpleasant shock to many tour operators in Rwanda. "We were not prepared for this increase at all," one tour operator, who wished not be identified, said. "Now half of my clients will go to Uganda instead, where a gorilla permit costs only $500."
Betting on more gorillas
The results of the latest mountain gorilla census will be announced at the end of this year, an exciting moment for Uwingeli, Vecellio and their colleagues, who've been working tirelessly to save these animals.
Are the gorillas faring as well as they hope? Or will they be disappointed?
Vecellio and her fellow conservationists are betting on their success. "I'm not going to mention any numbers," she says, "But I'm very optimistic. I think we're winning this fight."
All seven species of great apes share the following characteristics: no tail, a large skull with a large brain, a curved spine and an opposable or prehensile thumb. Like the chimpanzee, which is at home in central Africa and known for its often aggressive behavior.
The Bonobo, or pygmy chimpanzee, is a really peaceable ape. "Make love, not war" is its motto. Bonobos use frequent sex to ease tension in the group; they are also into French kissing and oral sex. Bonobos only live in the Democatic Republic of Congo.
There are two species of orangutans: one lives on the island of Borneo, the other on Sumatra. Both live on trees, have very long arms and hand-like feet that they use for climbing. Bornean orangutans are squat, they are heavier than their cousins on Sumatra, and their fur is darker and longer.
The Sumatra orangutan's fur is more reddish than that of the Borneo orangutan, the males' cheek pads are less pronounced and often covered in white hair. Sumatra orangutans also spend less time on the ground than their Bornean cousins. Experts suspect the reason to stay aloft may be the Sumatra tiger, which also preys on orangutans.
Gorillas are subdivided into two subspecies, the Eastern and the Western gorilla. The Eastern gorilla is bigger, its fur is darker, and the species is subdivided even further into the Eastern lowland and the Mountain gorilla (photo).
The Western gorilla is also subdivided, into the Western lowland (photo) and the profoundly endangered Cross River gorilla. Almost all gorillas in zoos are Western lowland gorillas. In the wild, there are far more Western gorillas than the Eastern species. The former also live in smaller groups.
Is there a great ape missing? Right: We, too are great apes. We humans are more closely related to chimpanzees and bonobos than the chimps are to gorillas. But we're the only great ape species that isn't threatened by extinction.
