She pretended to chew on wild celery and even thumped her chest—a symbol of power and strength in the gorilla world. From experimentation to conservation: Fossey arrived with the intent to simply study gorilla behavior and their habitat, but she soon became a fierce advocate and protector of the animal as well. Tipping point: Today, conservation efforts initiated by Fossey have doubled the mountain gorilla population at Volcanoes National Park, and the species is the only great ape experiencing a population growth.
Like rambunctious kids, young gorillas play tag and even do somersaults. And gorillas consider staring a sign of hostility. What are the main threats? Habitat loss More than , people live in the remote areas where mountain gorillas are found. Their need for land to cultivate has reduced the forest in which the gorillas live to virtual islands in the middle of expanding human settlements. Between and , large numbers of Rwandan refugees fled to camps at the edge of the Virunga National Park, leading to uncontrolled firewood harvesting as well as increased poaching see below.
Convoys of people from Rwanda and DRC destroyed large tracts of the park, home to mountain gorillas and other endangered species, to create agricultural and pastoral land. Hunting In addition to being hunted for meat, mountain gorillas are also illegally hunted for trophies and live infants. As many as 15 of Virunga's mountain gorillas may have been killed since the outbreak of civil war in Between and , when large numbers of Rwandan refugees fled to camps at the edge of the Virunga National Park, 4 habituated silverback gorillas were killed, along with some of their group members.
In , a further 7 gorillas were killed. While gorilla habitat does not currently fall within an oil concession, development in the park could negatively affect the animals' security. Disease As more people move into their habitat, and more tourists come to see them, mountain gorillas are becoming increasingly exposed to a variety of human ailments.
More on threats to gorillas More on illegal wildlife trade More on habitat loss. Livestock and human encroachment is a serious threat to Virunga National Park, an important protected area for mountain gorillas. What is WWF doing? Our 40 years of work to save the mountain gorilla and its forest habitat represents one of our longest-running flagship species programmes. Early gorilla surveys and aid to protected areas in the Albertine Rift ecoregion started in the s.
IGCP's mission is to empower the people of Rwanda, DRC and Uganda to jointly manage a network of transboundary protected areas that the mountain gorillas depend on.
Priority species Gorillas and other great apes are a WWF priority species. Learn more about the risk posed to gorillas and other biodiversity by this proposed exploration. How you can help Visit the gorillas! Money earned through gorilla tourism contributes significantly to the conservation of the species — providing funds for conservation projects and creating jobs and bringing other benefits to local communities living near gorillas.
Many large fruit trees depend upon these animals to survive. Research published in early showed that gorillas hum when contentedly when eating their favourite food. The oldest gorilla ever recorded was a female western gorilla at the Columbus Zoo that reached the ripe old age of 60 before dying in Gorillas build nests in which to sleep, both on the ground and in trees, made of leaves and branches.
Counting abandoned nests is an effective way for scientists to estimate population size. More helpfully, gorillas also have unique noseprints, which can be used to identify individuals from photographs by looking at the nostrils and the bridge of the nose. Gorillas plus chimps and bonobos are specialised knuckle-walkers. As knuckle-walkers, gorillas have various adaptations for stability and weight-bearing. Females usually produce just one baby every four to six years.
In total, a female will only give birth three or four times. Such a low reproduction rate makes it difficult for populations to bounce back following a decline. Scientists observed that mothers used more tactile and more repetitive gestures with their young than with other adults. A Carthaginian explorer named Hanno the Navigator was on an expedition to the African west coast in around BC when he came across a group of predominantly female primates that he described as savage, hairy women.
Gorillas are the largest primates, with a huge appetite for leaves, shoots, stems, roots and fruit. An adult consumes 18—20kg of food daily, mainly foliage, and will swallow many large seeds intact. As gorilla families move through the forest to forage, they defecate, thereby depositing seeds far away from the parent trees.
Crucially, gorillas like to build sleeping nests in areas with an open canopy, and next morning tend to poop in the vicinity before heading off.
