Site characteristics

Mount Nimba Strict Nature Reserve is located in the Nimba Mountains at the tri-national border of Guinea, Liberia and Côte d’Ivoire. It was designated a Strict Nature Reserve in 1944 (IUCN Category Ia) and is transboundary with Mount Nimba Integral Reserve (Côte d’Ivoire) and East Nimba Nature Reserve (Liberia, UNEP-WCMC and IUCN 2018). Unlike other protected areas in Guinea, Nimba was managed the Museum National d’Histoire Naturelle (Paris) and the Institut Français d’Afrique Noire (Dakar) after its creation (Brugière & Kormos 2009, Garnier & Martinez 2011). Consequently, the site as a long history of scientific studies (Garnier & Martinez 2011).
The reserve is now managed by the Centre for the Management of the Environment of Mount Nimba-Simandou (‘Centre National de Gestion de l’Environnement des Monts Nimba et Simandou‘, CEGENS) under the Ministry of Environment, Water and Forests and Sustainable Development, and fulfills administrative as well as scientific responsibilities (UNESCO 2018a).
The Nimba Mountains are a chain of mountains stretching across 40 km with the highest peak being Mount Nimba with 1,752m (Kormos & Boesch 2003). The area is characterized by a high plant and animal diversity and a high rate of endemism. The terrain is steep and the source if several rivers (Granier 2008). The habitat is moist forest up to 1,000 m altitude, but also includes grassland and wooded savanna (UNESCO 2018a). Due to strong seasonality and the abrupt change in altitude a variety of microclimates exist contributing to the high biodiversity (UNESCO 2018a). The most well-known endemic species are the Micropotamogale of Mount Nimba (Micropotamogale lamottei, a shrew), the viviparous toad of Mount Nimba (Nimbaphrynoides occidentalis) (UNESCO 2018a). In total, more than 317 vertebrate species, including 107 mammal species, more than 2,500 invertebrate species, and 2,000 plant species have been described (UNESCO 2018).
Mount Nimba Strict Nature Reserve has been a UNESCO World Heritage Site since 1981 and the only one in Guinea (UNESCO 2018). It covers both Guinea (125.4 km2) and Côte d’Ivoire (50 km2). However, due to the threat of iron mining and the arrival of a large number of refugees from Liberia it has been listed as World Heritage in Danger since 1992 (UNESCO 2018a). Since 1980 the Guinean part of the Nimba Mountains is also part of the Mont Nimba Biosphere Reserve that also includes Déré forest and Bossou hills (UNESCO 2011).
Even though the avifauna is not well studied in the Guinean part of the Nimba Mountains, its diversity is assumed to be similar to the Liberian part of the mountain range, and the area is consequently recognized as an Important Bird Area (BirdLife International 2018a).

Ape status

Surveys in different parts of the Nimba Mountains confirmed the presence of western chimpanzees (Sugiyama 1995, Shimada 2001). From the beginning these surveys were also aimed to study chimpanzee behavior, such as nesting behavior and tool-use behavior (details below). In the Regional Conservation Action Plan for western chimpanzees in 2003 the Nimba Mountains were identified as an ‘Exceptionally Important Priority Area’ (Kormos & Boesch 2003). Detailed surveys on chimpanzee density distribution were conducted by Nicolas Granier during multiple surveys after 2006 that focused on the eastern part of the protected area and the southern slope of Mount Nimba (Granier 2011, Granier et al. 2014). A transect survey conducted by the Wild Chimpanzee Foundation estimated the chimpanzee population in the reserve at around 166 individuals (WCF 2012). 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). Long-term chimpanzee research has been ongoing at the Seringbara study site since 2003 on the Guinean side of the Nimba Mountains (Koops 2011). The Seringbara study site is on the western side of the Nimba Mountains, in the foothills adjacent to the small village of Seringbara in south-eastern Guinea (7° 37’50.0”N, 8° 27’44.7”W). Since 2003, Kathelijne Koops 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 only partly habituated to human observers due to the extremely rugged nature of the terrain. For more information on the study site, see Koops (2011), Koops et al (2007; 2010; 2012a, b; 2013; 2015, 2019) and Fitzgerald et al. (2018).

Threats

Since 1992 Mount Nimba Strict Nature Reserve is listed as a ‘World Heritage in Danger’ because of plans to mine iron ore inside the reserve and an increase in anthropogenic pressure due to the arrival of refugees from Liberia (UNESCO 2018). Insufficient institutional structure was also reported as a threat (UNESCO 2018). As a result the boundary of the reserve were changed by the World Heritage Committee in 1993 and 15.5 km2 were degazetted so that mining operations could take place (Brugière & Kormos 2009).

Population density is high in the area around the reserve, also as consequence of mining activities in the Nimba Mountains. Consequently, poaching, wood extraction, land conversion to agriculture and cattle grazing using fires, and harvesting of medicinal plants is very prevalent across the area (Shimada 2000, WCF 2012, BirdLife International 2018b, UNESCO 2018a). In a nation-wide survey across 12 sites in Guinea, the Wild Chimpanzee Foundation concluded that Nimba was the most threatened site with 3.94 signs of human activity per km (WCF 2012). The most prevalent threat was poaching (2.74 signs/km), followed by agriculture, and wood extraction (WCF 2012). Agricultural activities have been on-going for decades especially in the northern part close to Seringbara and around Thuo towards the Liberian border (WCF 2012).

According to the World Heritage Centre, the Guinean government arranged for all mining operations to halt in the reserve and that mining permits had been withdrawn (UNESCO 2018b). However, mining will commence in the mining enclave, a part of the World Heritage Site that has been declassified. The World Heritage Center concluded that provided information was ambiguous, and that Environmental and Social Impact Assessments had not yet been implemented by mining companies or did not confirm to international standards (UNESCO 2018b). In addition, there are plans to tarmac a road from Lola (Guinea) to Danané (Côte d’Ivoire) that would pass by Mount Nimba and likely negatively impact biodiversity due to pollution, increased poaching and illegal logging (UNESCO 2018b).

Conservation activities

The governmental unit responsible for the administration of the reserve is the Centre for the Management of the Environment of Mount Nimba-Simandou (CEGENS) under the Ministry of Environment, Water and Forests and Sustainable Development, and fulfills administrative as well as scientific responsibilities (UNESCO 2018a). The project ‘Ministry of Environment, Water and Forests and Sustainable Development’ by Fauna & Flora International and funded by the Darwin Initiative established a transboundary biodiversity governance platform with the aim to compile data, build capacity and improve stakeholder collaboration (2009 -20012, Darwin Nimba Project). The project also received follow-up funding from USAID, but whether it is still operational as of 2018 is not clear. Activities included stakeholder consultation, capacity building through workshops and data compilation (Darwin Nimba Project). The nine-month project ‘Strengthening capacity of local communities to sustainably manage Mount Nimba’s natural resources’ headed by BirdLife International and financed by the Critical Ecosystem Partnership Fund’s (CEPF) was implemented by the ‘Initiative de Base pour la Gestion des Ressources Naturelles’ (IBGRN) until February 2018 (BirdLife International 2018b). The project established community groups, youth-led or women-led, and also two networks of traditional healers and hunters, and the groups also received legal status. Implemented activities included workshops and trainings in “micro-projects, internal governance, financial management, marketing, advocacy and communication” (BirdLife International 2018b). In addition, group members were trained in gardening and farming practices, and use of fuel efficient stoves with the aim to reduce reliance on natural resources from the protected area (BirdLife International 2018b). Conservation interventions at the Seringbara study site implemented by the Institut de Recherche Environnementale de Bossou (IREB) and Kyoto University Primate Research Institute (KUPRI) include environmental education, community projects, and snare removal www.greencorridor.info.

Research activities

The Nimba Mountains have been the focus of research for several decades. In the 1940’s a research station was established in Ziéla, to the North of the Nimba Mountains, and researchers including Maxime Lamotte, Roger Roy, and other scientists from the Institut Français d’Afrique Noire in Dakar, conducted studies on the fauna and flora, but also on climate and geology (Granier & Martinez 2011). In the context of the recognition of Nimba as a World Heritage Site several missions have been conducted by UNESCO (UNESCO 2018b). Many other organizations conducted research here, for example on the Nimba toad (Hillers et al. 2008, Sandberger-Loua et al. 2016). Studies targeted at chimpanzees in the Mount Nimba Strict Nature reserve, also investigated chimpanzee behavior, such as tool use (Sugiyama 1995, Shimada 2000), but also habitat use and nesting behavior (Granier et al. 2014). Established in 2003, 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. Long-term chimpanzee research is ongoing at the Seringbara study site in Guinea. 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) and conservation strategies (Fitzgerald et al. in prep).

Behaviours

Exposure to climate change impacts

As part of a study on the exposure of African great ape sites to climate change impacts, Kiribou et al. subm. extracted climate data and data on projected extreme climate impact events for the site. Climatological characteristics were derived from observation-based climate data provided by the Inter-Sectoral Impact Model Intercomparison Project (ISIMIP, www.isimip.org). Parameters were calculated as the average across each 30-year period. For 1981-2010, the EWEMBI dataset from ISIMIP2a was used. For the two future periods (2021-2050 and 2071-2099) ISIMIP2b climate data based on four CMIP5 global climate models were used. For future projections, two Representative Concentration Pathways (RCP) were used. RCP 2.6 is a scenario with strong mitigation measures in which global temperatures would likely rise below 2C. RCP 6.0 is a scenario with medium emissions in which global temperatures would likely rise up to 3C by 2100. For the number of days with heavy precipitation events, the 98th percentile of all precipitation days (>1mm/d) was calculated for the 1979-2013 reference period as a threshold for a heavy precipitation event. Then, for each year, the number of days above that threshold was derived. The figures on temperature and precipitation anomaly show the deviation from the mean temperature and mean precipitation for the 1979-2013 reference period.

The estimated exposure to future extreme climate impact events (crop failure, drought, river flood, wildfire, tropical cyclone, and heatwave) is based on a published dataset by Lange et al. 2020 derived from ISIMIP2b data. The same global climate models and RCPs as described above were used. Within each 30-year period, the number of years with an extreme event and the average proportion of the site affected were calculated (see Kiribou et al. subm. for details).
