Diécké is a forest in southern Guinea close to the border with Liberia (7°39'N - 7°21'N and 9°06'W - 8°47'W) and was designated as a Classified Forest in 1945 (IUCN category not reported, [https://www.protectedplanet.net/diecke-classified-forest UNEP-WCMC and IUCN 2018]). The forest is located in Guinée forestière, one of four Guinean natural regions, and is part of the region N'Zérékoré. It is about 100km west of Bossou and 950 km from the Guinean capital Conakry (Carvalho 2011). The forest has a size of 640 km², 70% of which are dense forest and the remainder being sparsely forested areas, fallows, and open land ([http://www.wildchimps.org  WCF 2012]). Diécké forest has a rich biodiversity with hippopotamus (''Hippopotamus amphibius''), duikers, and several primate species, including chimpanzees (WCF 2012). It is also listed as an Important Bird Area and harbors several species of plants and amphibians. Together with Ziama forest, this is one of the last remaining large forest blocks in southern Guinea. The terrain is partly hilly and ranges in altitude from 50-800m (Carvalho 2012).

Based on a nation-wide questionnaire survey, the presence of western chimpanzee was confirmed by Sugiyama & Soumah (1988). In a nationwide survey Rebecca Kormos identified Ziama Biosphere Reserve as the second most important priority area for western chimpanzee conservation in Guinea due to high chimpanzee densities encountered during reconnaissance surveys (Ham 1998). A nationwide survey by the Wild Chimpanzee Foundation estimated the chimpanzee population size at around 80 individuals (WCF 2012).

Illegal poaching represents the major threat to the chimpanzee population in the park (WCF 2012, Ham 1998). More than 500,000 immigrants migrated to this area beginning in 1989 from Sierra Leone and Liberia resulting in a strong increase in illegal logging (Carvalho 2011). There was also an increase in plantations of oil palm, rubber, and crops (Carvalho 2011).

West Africa > Republic of Guinea > Diécké Classified Forest

Summary[edit]

Loading map...
  • Western chimpanzees (Pan troglodytes verus) are present in Diécké Classified Forest.
  • It has been estimated that 80 (CI: 25-253) individuals occur in the forest.
  • The chimpanzee population trend is unknown.
  • This site has a total size of 640 km².
  • Key threats to chimpanzees are poaching and habitat destruction.
  • The following conservation activities were conducted by the Centre Forestier de N'Zérékoré: land-use planning, reforestation and monitoring of illegal hunting.
  • Diécké Classified Forest is one of the last biodiversity rich forest blocks remaining in southern Guinea.

Site characteristics[edit]

Diécké is a forest in southern Guinea close to the border with Liberia (7°39'N - 7°21'N and 9°06'W - 8°47'W) and was designated as a Classified Forest in 1945 (IUCN category not reported, UNEP-WCMC and IUCN 2018). The forest is located in Guinée forestière, one of four Guinean natural regions, and is part of the region N'Zérékoré. It is about 100 km west of Bossou and 950 km from the capital Conakry (Carvalho 2011). The forest has a size of 640 km², 70% of which are dense forest and the remainder being sparsely forested areas, fallows, and open land (WCF 2012). Diécké forest has a rich biodiversity with hippopotamus (Hippopotamus amphibius), duikers, and several primate species, including chimpanzees (WCF 2012). It is also listed as an Important Bird Area and harbors several species of plants and amphibians. Together with Ziama forest, this is one of the last remaining large forest blocks in southern Guinea. The terrain is partly hilly and ranges in altitude from 50-800m (Carvalho 2012).

Ape status[edit]

Based on a nation-wide questionnaire survey, the presence of western chimpanzees was confirmed by Sugiyama & Soumah (1988). In a nationwide survey Rebecca Kormos identified Ziama Biosphere Reserve as the second most important priority area for western chimpanzee conservation in Guinea due to high chimpanzee densities encountered during reconnaissance surveys (Ham 1998). A nationwide survey by the Wild Chimpanzee Foundation estimated the chimpanzee population size at around 80 individuals (WCF 2012).

Threats[edit]

Illegal poaching represents the major threat to the chimpanzee population in the park (WCF 2012, Ham 1998). More than 500,000 immigrants migrated to this area beginning in 1989 from Sierra Leone and Liberia resulting in a strong increase in illegal logging (Carvalho 2011). There was also an increase in plantations of oil palm, rubber, and crops (Carvalho 2011).

Conservation activities[edit]

The Centre Forestier de N'Zérékoré is responsible for Diécké Classified Forest. In the 1990’s the forest was divided into three land-use zones, the outer two allowing for different degrees of human activities, while the core of the forest was designated a ‘integrally protected area’ (WCF 2012). After 2000 Progerfor (the Projet de Gestion des Ressources Forestières), a cooperation between Centre Forestier de N'Zérékoré and German partners, conducted conservation activities, including reforestation and monitoring of illegal hunting (Carvalho 2011).
