Of the two existing species of gorilla, the western lowland gorilla (Gorilla gorilla) is by far the more numerous and widespread. It can be found in Angola, Cameroon, Central African Republic, Congo, the Democratic Republic of the Congo, Equatorial Guinea, and Gabon.

These large great apes are mostly herbivores, eating seeds, leaves, fruit, and other plant matter. Western lowland gorillas live in family groups consisting of a dominant male, several females, and their young. They maintain relatively large home ranges in swamps and lowland forests, which provide food sources and nesting sites. Like other great apes, western lowland gorillas are long-lived, reaching 40 years in the wild and over 50 in captivity.

There are approximately 150,000 to 200,000 western lowland gorillas remaining in the wild today, but their population is declining quickly due to human activities. Despite universal legal protection from hunting, capture, and trade, these critically endangered apes are often poached for bush meat. As global demand for palm oil rises, large tracts of the western lowland gorilla’s forest habitat are threatened by conversion to plantations. Gorillas are also susceptible to disease epidemics, especially fast-spreading diseases like the Ebola virus, which can quickly wipe out large populations.

Current conservation plans call for careful planning of economic activities and increased awareness education for all local groups near gorilla habitats. Because the gorilla’s range crosses national borders, successful conservation efforts will require the coordination of multiple countries.

  1. What challenges do western lowland gorillas face from human and natural causes?

    • Answer

      Gorillas are threatened by poaching and habitat loss for agricultural uses, and are also susceptible to diseases like the Ebola virus.

  2. Where can western lowland gorillas be found, and what sort of habitat do they use?

    • Answer

      Western lowland gorillas can be found in the western African countries of Angola, Cameroon, Central African Republic, Congo, the Democratic Republic of the Congo, Equatorial Guinea, and Gabon. There they live in lowland forests and swampland.

  3. What actions have conservation plans suggested for the preservation of western lowland gorilla populations, and what complicates these actions?

    • Answer

      Conservation plans have suggested careful economic planning and increased education and awareness efforts. However, these plans are complicated by the fact that the western lowland gorilla can be found across several countries.
