Site characteristics

Nialama (or Nyalama) is located in the Fouta Djallon highland region in northern Guinea and was designated a Classified Forest (IUCN category not reported) in 1943 (UNEP-WCMC & IUCN 2019). It is 120 km northwest of Labé in the sub-prefecture of Linsan-Saran. It has a size of 100 km2 (UNEP-WCMC & IUCN 2019). Nialama is on and below a steep plateau, an area characterized by a mosaic of open savanna woodland with gallery forests, grassland, patches of bamboo and seasonal swamps (Sunderland-Groves et al. 2011, BirdLife International 2019). The annual rainfall is 1,145 mm (BirdLife International 2019). Due to its bird diversity Nialama is designated an Important Bird Area with a total size of 120 km2 consisting of Nialama CF and adjacent areas (BirdLife International 2019). Several primate species occur in the forest: western chimpanzees (Pan troglodytes verus), king colobus (Colobus polykomos), Guinea baboon (Papio papio), Campbell’s monkey (Cercopithecus campbelli), patas monkey (Erythrocebus patas), and Northern lesser galago (Galago senegalensis, Sunderland-Groves et al. 2011). In addition, 17 species of amphibians have been recorded in Nialama CF (Hillers et al. 2008).

Ape status

In a nationwide survey Rebecca Kormos confirmed the presence of western chimpanzees in Nialama CF (Ham 1998). Kormos identified Nialama CF as the third most important priority area for western chimpanzee conservation in Guinea due to high abundance of chimpanzees and remaining suitable habitat (Ham 1998). A follow-up survey in 1998 concluded that at least three chimpanzee communities occur in Nialama CF and additional four groups use the site periodically (Carter 2000 as cited in Kormos et al. 2003 and Sunderland-Groves et al. 2011). Janis Carter trained community members to monitor chimpanzees and set up a community-based monitoring system in which community members collected data monthly within and outside of Nialama CF (Sunderland-Groves et al. 2011). Funding for this project ceased in 2009 and the current status of the monitoring project was not reported (Sunderland-Groves et al. 2011).

Threats

The main threat to chimpanzees is habitat destruction and fragmentation as a results of the expansion of agricultural areas (BirdLife International 2019, Kormos et al. 2003, Sunderland-Groves et al. 2011). Two villages are located within Nialama Cf with a total population of several hundred inhabitants, and additional villages are located at the border of Nialama CF (Sunderland-Groves et al. 2011). The expansion of agricultural areas also resulted in an increase in frequency of negative chimpanzee-human interactions, for example crop raiding killing of young livestock by chimpanzees, conflict over water sources and wild fruits. Especially the first one can lead to the reduction in villager’s income. This is turn can lead to retaliatory hunting of chimpanzees by villagers (Carter 2004, 2008 as cited in Sunderland-Groves et al. 2011). Fires occur regularly to clear land for agriculture or foster the regrowth of new grass for cattle raising (PEGG 2012). Swamps are partly used for rice cultivation (BirdLife International 2019). At the end of 1980s large-scale logging took place (BirdLife International 2019).

Conservation activities

In 1998 as part of the project “Projet de Conservation de Chimpanzés” local hunters were trained to collect monitoring data on the number and movement of chimpanzees in Nialama forest (Kormos et al. 2003). The aim was to develop a low-cost long-term monitoring system of chimpanzees (Sunderland-Groves et al. 2011). Since 2000 a monthly, community-based monitoring system was implemented in the areas. In addition, in 1999 Nialama CF became the first forest in Guinea to be co-managed by local communities and the National Directorate of Water and Forests (DNEF) based on a legally binding agreement between the involved parties (Sunderland-Groves et al. 2011). Co-management implied that local communities and government authorities jointly make land and resource-use decisions as a part of a management plan. Specifically, this included ensuring that community members and forestry agents implement management activities, such as clearing and maintaining fire buffers, wildlife monitoring, enforcing rules for the sustainable use of wildlife and plants, tree replanting and demarcating the classified forest. At the same part communities can use timber and non-timber forest products from the forest, receive financial and technical support for farming and agroforestry in selected areas, all in accordance with rules set forth in the management plan (Sunderland-Groves et al. 2011). The project was funded by USAID until 2009. A study showed that habitat degradation was less prevalent in habitat that had been demarcated as critical for chimpanzees by the community-based project compared to other areas around Nialama CF (Sunderland-Groves et al. 2011). Noteworthy is also people’s traditional believes forbid the hunting and eating of chimpanzees, resulting in some level of protection to chimpanzees, but is not followed by all community members (Kormos et al. 2003, Sunderland-Groves et al. 2011).

Impediments

Lack of transportation for members of the village committee and the National Directorate of Water and Forests was mentioned as an impediment to implementing the management plan (PEGG 2012). Members that were newly elected to the village committee after the conservation project stopped did not receive training and lack capacity to fulfil their tasks (PEGG 2012).

Research activities

As detailed above surveys and long-term monitoring of chimpanzees has been implemented (Ham 1998, Sunderland-Groves et al. 2011). A study on amphibian diversity has also been done (Hillers at al. 2008).
