Why gorillas are endangered and why they are important

What are the problems facing gorillas?

The main threats to gorillas are:

• Hunt for bushmeat
• Habitat loss
• Wildlife trade
• Infectuous diseases

Bushmeat
The commercial trade in bushmeat, which occurs throughout west and central Africa, is today the biggest threat to African gorillas. 

Estimating numbers of gorillas poached is difficult because they are often butchered and eaten on the spot, or their meat is smoked for later sale in towns. 

Although gorillas may constitute only a small proportion of all animals killed for the bushmeat trade, they present easy targets for hunters, and in many areas gorillas are favoured by hunters because of the weight of saleable meat.

Gorillas’ low reproductive rates means that even low levels of hunting can cause a population decline, which could take many generations to be reversed.  Gorillas are also frequently maimed or killed by traps and snares intended for other forest animals such as antelopes.

Habitat loss
Forests are rapidly being destroyed by commercial logging interests, for subsistence agriculture and road building activities. This makes it harder for gorillas to sustain their lives.

There is also a strong link between habitat loss and the bushmeat trade. As previously inaccessible forests are opened up by timber companies, commercial hunters gain access to areas where gorilla roam and often use logging vehicles to transport bushmeat to far away markets, as well as sell meat to employees of the logging companies.
 
Hunting for medicine and the live animal trade
Gorillas are also sought after as pets or trophies and for their body parts, which are used in medicine and as magical charms.

Spread of infectious diseases, notably the Ebola virus
Since the early 1990s, outbreaks of Ebola hemorrhagic fever have caused large-scale die-offs of great apes.

The 1994 outbreak in Minkébé (northern Gabon) wiped out the entire population of what used to be the second largest protected population of gorillas and chimpanzees in the world.

Between 2002 and 2003 the virus claimed many human lives in the north of the Republic of Congo and at two study sites in and around Odzala National Park, 95 percent of the 600 identified gorillas died likely as a result of Ebola.

There seems to be a pattern in the way the outbreaks have occurred across the region, making it likely that they were not isolated events but part of a wave that may still be spreading across the region.
