- Wiki pages contain information in paragraphs, tables, lists, and images.

- Tables and lists are extracted as data, so the following restrictions apply to them:

  1) Table structure cannot be changed.

  2) List format should not change, i.e. they are comma separated lists, not bullet points or numbered lists.
 +
  3) To make information comparable across wiki pages, keywords must be taken from the list of permitted words, or added to the list of permitted keywords. This is why we use official lists, e.g., IUCN classification lists, in our tables.

Ivindo National Park is located in the central area of Gabon. The site was declared a national park in 2002. Archaeological findings near the park show human habitation as early as 120,000 BP ([https://programs.wcs.org/langouebai WCS]). Within the park, the famous Langoué baï is found. Langoué baï is an ancient forest clearing, frequently visited by forest elephants, gorillas, forest buffalos, red river hogs, and a resident population of sitatunga ([https://programs.wcs.org/langouebai WCS]). Langoué baï serves as the base for the Wildlife Conservation Society Gabon’s Forest Program, which protects and monitors populations of gorillas and elephants. Leopards, aardvarks, pangolins, and central chimpanzees are also found at the site. At least 397 species of birds have been identified at Ivindo, including the rare picarthes (Rayden & Essame Essono 2010).

The park is surrounded by forestry concessions, which can have negative impacts if the forestry companies do not adhere to legal requirements for the control of illegal hunting (Rayden & Essame Essono 2010). A 2010 study found that a large number of the forestry companies are not legally compliant and improvements need to be made to control illegal hunting in the surrounding concessions (Rayden & Essame Essono 2010).

Central Africa > Gabon > Ivindo National Park

Summary

  • Central chimpanzees (Pan troglodytes troglodytes) & western lowland gorillas (Gorilla gorilla gorilla) are present in Ivindo National Park.
  • The great ape population size is unknown.
  • The population trend is unknown.
  • The site has a total size of 3,000 km².
  • Poaching is a key threat to great apes at the site.
  • Conservation activities have focused on monitoring and research activities.

Site characteristics

Ivindo National Park is located in the central area of Gabon. The site was declared a national park in 2002. Archaeological findings near the park show human habitation as early as 120,000 BP (WCS). Within the park, the famous Langoué baï is found. Langoué baï is an ancient forest clearing, frequently visited by forest elephants, gorillas, forest buffalos, red river hogs, and a resident population of sitatunga (WCS). Langoué baï serves as the base for the Wildlife Conservation Society Gabon’s Forest Program, which protects and monitors populations of gorillas and elephants. Leopards, aardvarks, pangolins, and central chimpanzees are also found at the site. At least 397 species of birds have been identified at Ivindo, including the rare picarthes (Rayden & Essame Essono 2010).

The park is surrounded by forestry concessions, which can have negative impacts if the forestry companies do not adhere to legal requirements for the control of illegal hunting (Rayden & Essame Essono 2010). A 2010 study found that a large number of the forestry companies are not legally compliant and improvements need to be made to control illegal hunting in the surrounding concessions (Rayden & Essame Essono 2010).
