West African chimpanzee study sites  

Taï Chimpanzee Project

The Taï chimpanzee project is located in Cote d'Ivorie following 4 chimpanzee communities for over 40 years. The current relevant research focuses are long term demographic changes, intercommunity interactions and social bonds & cooperation. The communities live in an evergreen rainforest habitat, with 2 wet seasons (March-June; September-October) and 2 dry seasons (July-August; November-February) \cite{Doran_1997}.
Cote d'Ivorie is being severely afflicted by climate change - the mean average temperature over the past 5 years is more than 0.2°C hotter than it was the preceding 5 years, and the standard deviation in average rainfall has increased 5% in the same time. 

Fongoli Savanna Chimpanzee Project

The Fongoli Savanna Chimpanzee project is located in Senegal, and is the northern-most study site of wild chimpanzees in the world. Since 2001, the project has been studying a community There is one long dry season (November–April) and a short wet season (June–September), with May and October being transitional months when some rain may fall. Maximum temperatures at Fongoli exceed 40°C during the late dry season (Pruetz 2007), and chimpanzees are reduced to between two and four permanent water sources available during the peak of the dry season. Rainfall before 2010 averaged less than 1,000 mm annually, but between 2010 and 2015 rainfall has become more erratic, with some wet years of >1,000 mm and some very dry years. This pattern matches the drying (Galat-Luong and Galat 2005) and warming trend noted in the region (Hillyer, Armstrong, and Korstjens 2015) and has implications for further environmental pressures on primates here.

Central African chimpanzee study sites  

Loango Chimpanzee Project

This study site was established in 2005 in Loango National Park, Gabon. The Loango community is bordered by 5 other chimpanzee communities. The area consists of a mosaic of rivers, swamps, coastal forests, mangroves, savannahs, and secondary and mature forests. Temperatures range between 18 and 32 °C, with the mean minimum and maximum temperatures being 22.7 °C and 27.8 °C, respectively. There is a long rainy season between October and April, interrupted by a short dry season between December and January. The long dry season usually lasts from May to September (Head et al. 2011).
