- Wiki pages contain information in paragraphs, tables, lists, and images.
- Text and images are not restricted, and their formats can be chosen as desired.
- 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.

= Summary = <!-- An overview of the site, with one sentence for each section. May include a site map -->
* Western chimpanzees (''Pan troglodytes verus'') are present in Banco National Park.
* It has been estimated that around 26 individuals occur in the site.
* The chimpanzee population trend is stable.
* The site has a total size of 34 km².
* Key threats to chimpanzees are pollution, hunting, and pressure from urban surroundings.
* Conservation activities have focused on conservation and environmental awareness campaigns and education.
* The site is surrounded by the capital city of Abidjan.
= Site characteristics = <!-- A paragraph summary of physical and geographic aspects of the site, and a table of key information -->
The Banco National Park was created in October 1953. It is located in the heart of the Ivorian economic capital, Abidjan, and is bounded by the municipalities of Adjamé, Attécoubé, Abobo, and Yopougon. The surface of the park has shrunk over the years and now covers an area of 3,438 hectares. Being the unique remaining relic of the dense primary forest that once covered the area of Abidjan, Banco National Park is often described as the hydraulic reservoir and green lung of the economic capital of Côte d'Ivoire. This protected area is a center for environmental education (OIPR 2020). The park holds about 600 ha of primary forests; an arboretum of over 800 species of higher plants native to the tropics of Africa, Asia and Latin America; many fish ponds located in the heart of the park, a semi-natural swimming pool, an ecomuseum, and the presence of a family of chimpanzees (OIPR 2020).
Based on a wildlife survey (Bitty et al. 2013), the site is home to a number mammal species, including primates (chimpanzees, Campbell's mona monkey, and lesser white-nosed monkey), ungulates (harnessed bushbuck, Maxwell's duiker, Royal antelope), and predators, such as the cape genet, common kusimanse, and African civet (OIPR 2020).

= Ape status = <!--An overview of ape population status (population sizes, trends, etc.), followed by a table of specific surveys and results -->
A marked nest count study conducted in the Banco National Park in 2006 confirmed the presence of a small chimpanzee population. Twentysix fresh nests (including single nests and a group of up to 5 nests) were found along transects, and 5 off transects. The population was estimated to be around 20 individuals. In 2006, assistants succeeded several times to directly observe chimpanzees in groups of over ten individuals (WCF n.d.). Visitors of the park sighted ca. 20 chimpanzees in 2013 (Normand, E., personal communication). The manager of the park supports a group of up to 40 chimpanzees, and 3-4 isolated individuals are occasionally seen in the park (Bakayoko, H, pers. com). Based on these corroborating statements, the population of chimpanzees within the site is likely stable or increasing.

= Threats = <!-- a text overview of threats, followed by a table of key threats -->
Banco National Park is highly threatened by the neighboring populations, which exert a high pressure on the fauna and flora of the park. Snares are regularly found and poachers caught, illustrating that poaching is very much present within the park. Pollution is a real challenge for the park. The different types of pollution caused by domestic, artisanal, or industrial discharges destroy trees and pollute the land over an average distance of 200 m around the sources of pollution (Kouadio & Singh 2020).
The park's isolation in the urban area of Abidjan and various types of human activities near the park are the main cause of the pollution observed. In Abobo, to the north and north-east of the park, the various economic activities linked to the sale and repair of automobiles, in particular, the “Abidjan Automobile Casse”, lead to the rejection of a large quantity of abandoned spare parts in the park forest. In addition, engine oils are discharged into polluted water drainage channels which then flow into the park (Kouadio & Singh 2020).
The second source of pollution in the Banco forest include the septic waste from the neighboring communities and the Abidjan main detention center (MACA), the largest prison in Côte d'Ivoire, located at the southwestern edge of the park. Waste from septic tanks is also discharged into the park. The park is also bordered by several Small and Medium Industrial Enterprises, and also by small artisanal production units of traditional soaps made by chemical fermentation. These units are located to the north-east in the commune of Adjamé and to the south-west in Yopougon. The liquid waste produced by these units is directly discharged into the park (Kouadio & Singh 2020).
