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.).
