To assess the population of chimpanzees living outside Gombe National Park, Tanzania, we conducted surveys of village lands 10 — 20 km north of the park (5-9 October 2015 and 4-10 May 2016), integrating these findings with data from DigitalGlobe satellite images and community forest monitoring data. Surveys recorded the number and GPS location of chimpanzee nests, fecal samples, and sightings, preserving fecal samples in RNAlater. In 2015, we found 183 chimpanzee nests, 3 fresh fecal samples, and saw 3 parties of chimpanzees, including one with ≥ 5 individuals. From 2012-2016, village forest monitors reported 138 nests, heard chimpanzees 10 times, and saw chimpanzees 3 times. The 2015 fecal samples tested negative for SIVcpz, and were from at least two previously uncharacterized individuals. In 2016, surveys found 7 chimpanzee nests and 2 sites with fecal samples, but did not see chimpanzees. These two surveys and community data both found that chimpanzees persist near the park. Nonetheless, it was evident from both satellite images and surveys that people are rapidly converting forest and woodland to farms. While these areas have been established by communities as Village Forest Reserves, new actions and resources are needed to enforce village land use plans and ensure the protection of these chimpanzees and their habitats.
