<!-- INSTRUCTIONS FOR COMPLETING Site INFORMATION
 +
- Wiki site pages contain information in paragraphs of text, tables, keyword lists, and images
 +
- Text paragraphs and images are not restricted, so text format and images can be chosen as desired.
 +
- Tables and keyword lists are extracted as data, and so have the following restrictions:
 +
  1) Table structure cannot be changed
 +
  2) Keyword format should not change, i.e. they are comma separated lists, not bullet points or numbered lists.
 +
  3) Keywords must be taken from the list of permitted words, or added to the list of permitted keywords. A link to the keyword list page is found adjacent
 +
    to the relevant table or keyword list. This ensures that the same keyword always refers to the same concept, e.g. Everybody uses "Industrial mining",
 +
    rather than several keywords such as "Industrial mining", "Large-scale mining", and "Mining".

* Western chimpanzees ([https://www.iucnredlist.org/species/15935/17989872 ''Pan troglodytes verus'']) are present in the Fongoli Savanna Chimpanzee Project (FSCP) area.
 +
* As of 2019, 32 individuals occur in the site.
 +
* The chimpanzee population trend is stable.
 +
* This site has a total size of 90 km².
 +
* Key threats to chimpanzees are artisanal mining, resource competition, and habitat loss.
 +
* This community of chimpanzees has been studied since 2001 and habituated since 2005. They are the only known chimpanzee community to hunt their prey with sharpened sticks. These chimpanzees also evade the heat of their environment by soaking in free-standing water, using caves, and staying active after night fall.

The Fongoli Savanna Research Project (FSCP) was established by Dr. Jill Pruetz following the identification of a strong local chimpanzee population near to the Gambia River and north of Kedougou, in the Kedougou Region of Southeastern Senegal.  The research site is located outside of any formal protected area but the area designated as ‘Zone d'Intérêt Cynégétique Faleme’ (ZIC Faleme), zone within which hunting is strictly regulated. The site overlaps with several villages, and lies in relatively close proximity to the regional capital of Kedougou. The habitat can be described as a savanna-woodland mosaic, located within the vegetation Sudano-Guniean belt (Ba et al. 1997). Fongoli, like the broader region, experiences marked seasonality in climate, with rainfall concentrated to a short wet season and a lengthy dry season. Temperatures during the dry season frequently exceed 40deg C, often exceeding 45C in the months of April and May (Wessling et al. 2018). Other primates living at Fongoli are Guinea baboons (''Papio papio''), green monkeys (''Chlorocebus aethiops''), patas monkeys (''Erythrocebus patas''), and bushbabies (''Galago senegalensis''). All four sympatric primates are consumed by the chimpanzee research community. In addition to these primates, warthog (''Phacochoerus africanus''), banded mongoose (''Mungos mungo''), bushbuck (''Tragelaphus scriptus''), porcupine (''Hystrix cristata''), hyena (''Crocuta crocuta''), leopards (''Panthera pardus''), and honey badgers (''Mellivora capensis'') can be found at the site (Lindshield et al. 2019).

The Fongoli chimpanzees have been under research since initial surveying in 2001 (Pruetz et al. 2001), and males have been fully-habituated to researcher presence since 2005. The chimpanzee community ranges in size between 28 and 36 individuals. Density estimates for the site have also been formally conducted in 2013 (0.29 indiv./km²), although they underestimated true chimpanzee densities at the time (0.35 indiv / km²; Wessling et al. in review).

''Saba senegalensis'' is an important food resource for the Fongoli chimpanzees while likewise consistently extracted for sale in local and national markets (Waller and Pruetz 2014). In the last decade Fongoli has become a target of timber extraction, likely due to its proximity to the regional capital and ease of access. Transient pastoral communities pass through Fongoli and cut branches from an assortment of tree species to be used as fodder for their livestock. The Kedougou Region, in which Fongoli is located, has experienced a mining boom since the early 2010s, and temporary to semi-permanent mining camps have been established within the research area, with demonstrated effects on the home range use of the research community (Boyer-Ontl 2017). Poaching is not a consistent threat at the site, however in 2009 a poacher obtained an infant of the research community, which was later returned to the group by researchers (Pruetz and Kante 2010).

Since the inception of the research project, a permanent research presence has existed at the Fongoli site since 2001. Local personnel are employed with the project, and sensibilization programmes began at Fongoli and in the region to educate local populations about chimpanzees. Researchers take care to prevent communicable diseases to the apes, including strict minimum distance guidelines, wearing face masks, and requirement of vaccinations and good health to access the site.  [https://www.globalgiving.org/donate/10235/neighbor-ape/  Neighbor Ape], a non-profit for the conservation of chimpanzees in Senegal, was established by Fongoli Director Dr. Jill Pruetz, and conducts frequent assistance programs to local communities of the immediate and broader Fongoli region. Details on smaller projects are listed [https://www.globalgiving.org/donate/10235/neighbor-ape/ here].

The Fongoli chimpanzees have been under study since 2001 and were fully habituated by 2005. A permanent research presence has existed at the site since the start of the project. A wide range of topics have been studied at the Fongoli site, including aspects related to behavior, culture, feeding ecology, physiology, isotopes, parasite loading, enthoprimatology, and sociality, among many others.
