West Africa > Republic of Guinea > Seringbara
Summary
- Western chimpanzees (Pan troglodytes verus) are present in Seringbara.
- It has been estimated that more than 100 individuals reside in two communities (Koops et al. in prep.).
- The chimpanzee population trend is unknown.
- This site has a total size of 30 km².
- Threats to chimpanzees are habitat encroachment, disease, hunting (snares), and iron ore mining
- Conservation activities include environmental education, snare removal, and local community projects.
- Seringbara permanent chimpanzee research site was established in 2003.
Site characteristics
The Seringbara research area is located within the Mont Nimba Strict Nature Reserve on the western side of the Nimba Massif in southeastern Guinea. The area is adjacent to the village of Seringbara, approximately 6 km from Bossou, Guinea and 10 km from Yealé, Cote d’Ivoire (Koops 2011). It is separated from the Bossou hills by a 4 km stretch of savanna, an area that has been the focus of reforestation efforts by the Green Corridor Project. The Seringbara research area is largely composed of primary tropical forests, but as the terrain becomes steeper, it transitions to a mosaic of terrestrial herbaceous vegetations, montane forest, and high-altitude grasslands (Koops 2011; Fitzgerald et al 2018). The elevation ranges from 595 to 1520 m and the climate is characterized by a rainy season (February to October) and a 3-month dry season (November to February, Koops et al. 2012a, b; Koops et al. 2013).

Ape status
Since 1976, several surveys have been conducted in the Seringbara region by Sugiyama, who visited the area at least four times to interview the local population on chimpanzees, suggesting chimpanzees were present in the area. During his visits he also did two field surveys of the area (Shimada 2000). Shimada confirmed the presence of chimpanzees by recorded vocalizations and the presence of nests in 1999 (Shimada 2000). While it was at first thought that chimpanzees use this area only seasonally, more systematic surveys in 2000 and 2001 established the presence of at least one chimpanzee community (Humle & Matsuzawa 2001). Since 2003, Kathelijne Koops (in collaboration with Kyoto University Primate Research Institute, KUPRI) has directed research at the Seringbara study site and researchers and field assistants have maintained a near-constant presence at the site. The study population remains partly habituated to human observers. For more information on the study site, see Koops (2011) and Koops et al (2007; 2012a, b; 2013; 2015, 2019). With the establishment of the permanent research site in 2003 the presence of at least two chimpanzee communities was confirmed and chimpanzee density estimated at 1.72 individuals/km2 (Koops 2011). Genetic analyses are currently ongoing and include 707 chimpanzee faecal samples collected at the Seringbara study site between 2003-2014 (Koops et al. in prep.).

Research activities
Initial research at Seringbara focused on tool use behaviour by the Nimba chimpanzees especially in comparison to the chimpanzees at Bossou (e.g., Humle & Matsuzawa 2001, Koops 2011, Shimada 2000, Sugiyama 1995). Subsequently, Seringbara research broadened to include chimpanzee tool use patterns (Koops et al. 2013, 2015), feeding ecology (Koops 2011, Koops et al. 2013, 2019), grouping and ranging patterns (van Leeuwen et al. in press), nesting behaviour (Koops et al. 2007, 2012a,b), habitat suitability modeling (Fitzgerald et al. 2018), molecular genetics (Koops et al 2012b, Koops et al. in prep), nutritional analyses (Koops et al. 2019), land cover change analyses (Fitzgerald et al, in prep) and conservation strategies (Fitzgerald et al. in prep).
