= Summary = <!-- An overview of the site -->
The Fongoli Savanna Chimpanzee Project (hereafter referred to as the FSCP) was first surveyed in 2000 by Dr. Jill Pruetz, and subsequently a research station was established in 2001. The FSCP habitat is described as sudano-guniean mosaic habitat, including gallery forest, open and closed woodlands, grassland savannas, open plateaus, ecotone, and other habitat types. The climate of the FSCP site is relatively extreme (Wessling et al. 2018b), with an average of 945mm rainfall per year (FSCP longterm database) a nine-month dry season, and an average daily maximum temperature of 37deg C (Wessling et al. 2018a). Possibly due to these environmental extremes, the FSCP site is located in the northwestern limit of the western chimpanzee biogeographical range. Interesting insights from FSCP research has illuminated unique behaviors demonstrated by savanna chimpanzees, including cave use, pool use, and tool assisted hunting (see Behaviors section below).

= Site characteristics = <!-- -->
The FSCP was founded in 2001 by Dr. Jill Pruetz (Texas State University, USA) following initial surveying conducted by Dr. Pruetz and her collaborators (Pruetz et al. 2002). The Fongoli site was selected for the creation of a long-term research site based on it's high density of chimpanzee nests relative to other locations in the Kedougou Region of Senegal. Habituation efforts were underway from 2001-2005, until in 2005 all male individuals of the community were fully habituated and research effort intensified.
The FSCP (12°40'N, 12°13'W) is located within the Tomboronkoto Arrondissement of the Kedougou Region (southeastern Senegal) and is managed by the Departement des Eaux et Forets des Chasses de Senegal. The project area encompasses an area of approximately 100km² (the size of the Fongoli chimpanzee community home range). A number of villages surround the community, including a number of ethnic groups (Bassari, Bedik, Pulaar, and Malinke; Pruetz 2013).

Initial surveying of Fongoli suggested the Fongoli area (identified in Pruetz et al. 2002 as Tomboronkoto) to be of highest chimpanzee for the region, with a chimpanzee encounter rate of 285 chimpanzee signs per 5.8 km walked. To date, no formal surveying has been conducted in Senegal to confirm true abundance estimates relative to other sites. However, as of 2018 32 individuals belong to the research community, although it has varied in size from X to X since 2005. Surrounding communities to the northwest have been estimated to be between 9 and 18 individuals, at a similar estimated density as that observed at Fongoli (Micheletti 2018), although no abundance estimates were provided.
<br>
= Threats = <!-- a text overview of threats, followed by a table of key threats -->
Traditionally, resource extraction (e.g., Saba senegalensis fruits, Khaya senegalensis and Pterocarpus erinaceus wood) has been the predominant threat to chimpanzee habitats in Senegal, and these threats have been previously studied at Fongoli (e.g., Clavette X, Mara X). Chimpanzees in the region are not a hunted species but in 2009 a hunter opportunistically captured an infant chimpanzee from the research community after injuring its mother (Pruetz and Kante 2010). The hunter attempted to sell the infant as a pet before it was confiscated and returned to its natal community. Therefore, it appears that chimpanzees at Fongoli and in the region in general are vulnerable to opportunistic hunting.
Agriculture
More recently, artisinal gold minign has increased anthropogenic pressure on Fongoli chimpanzees, as several mining sites have opened within the FSCP territory. Along with increased exposure to toxins (e.g., mercury) in the environment, artisinal mining has also been shown to have an impact on movement patterns of the chimpanzees.

Neighbor Ape was founded by Dr. Pruetz as a means of supporting local communities surrounding the FSCP (link). The charity has undertaken a varied number of approaches towards supporting these communities, including funding individual and village-wide health projects, school fees and supplies, and other education-related endeavors such as founding a housing project to support students from local villages (OBRAR: link).

Artisinal gold mining is a challenging threat to overcome to chimpanzee conservation at FSCP, as it is viewed by the local population as a significant means of income. Likewise, agricultural production within and surrounding the FSCP is a traditional means of sustaining the local population (commonly subsistence farmers), and therefore is unlikely to be eradicated.

The FSCP site was first surveyed in 199 as part of larger-scale surveying in the region (Pruetz et al., 2002). Since then, the FSCP community has been under continuous research since 2001, with all males of the community habituated to researcher presence since 2005. Research at Fongoli has been predominately behavioral (see below), although ecological (Bogart and Pruetz 2011), endocrinological (Wessling et al. 2018a,b), and isotopic research (Sponheimer et al. 2006) have also been conducted there. Research activities have also recently extended to neighboring chimpanzee communities (e.g. X).
