Two classified forests, located right next to each other separated by the river Gambie, were established in 1952, Woundou North and Woundou South ([http://www.wildchimps.org  WCF 2012]). Gadha Woundou does not have a designated IUCN category nor is it listed in the World Database on Protected Areas ([https://www.protectedplanet.net/country/GN  UNEP-WCMC and IUCN 2018]). The habitat is characterized by a mosaic of wooded savanna, savanna grassland, gallery forests and bamboo forests (WCF 2012). The presence of jackals (''Canis sp.''), leopards (''Panthera pardus''), green monkeys (''Chlorocebus sabaeus''), Guinea baboons (''Papio papio''), and patas monkeys (''Erythrocebus patas'') has also been confirmed (WCF 2012).

In 1997, Rebecca Kormos conducted reconnaissance surveys in Gadha Woundou and confirmed the presence of western chimpanzees (Ham 1998). I.S. Camara surveyed Woundou North Classified Forest and estimated the chimpanzee population at more than 500 individuals (Camara 2007, report not in the public domain, details cited here were taken from WCF 2012). In 2011, the [http://www.wildchimps.org  Wild Chimpanzee Foundation] also surveyed Woundou North in collaboration with the Office for Biodiversity and Protected Areas Guinea (OGuiBDPA) (WCF 2012). They estimated that around 50 chimpanzees occur in the area, but noted that this was an underestimate because they encountered a group of 50 individuals while other survey teams noticed two additional chimpanzee groups (WCF 2012). In savanna mosaics chimpanzee nests are mainly found in gallery forests and a systematic survey design can lead to underestimations in such fragmented habitat (WCF 2012).

Around 5.600 people are living in proximity to Gadha Woundou (Camara 2007). Human density in Woundou North Classified Forest is low with seven villages around the site (WCF 2012). Roads to these villages are, however, not passable year round. A survey of anthropogenic signs found paths to be most prevalent, followed by slash and burn agriculture, traditional hunting and wood extraction (WCF 2012). Chimpanzees are not hunted and there were no signs of commercial hunting (WCF 2012).

West Africa > Republic of Guinea > Gadha Woundou Classified Forest

Summary[edit]

Loading map...
  • Western chimpanzees (Pan troglodytes verus) are present in Gadha Woundou Classified Forest.
  • Estimates for the chimpanzee population range between 50 and 500 individuals.
  • The chimpanzee population trend is unknown.
  • The total size of the area has not been reported.
  • Agriculture and roads are the most prevalent signs of human activity in Gadha Woundou.
  • Local residents have established forest monitoring committees.

Site characteristics[edit]

Gadha Woundou is a sub-prefecture located in Northern Guinea in the prefecture Koubia in the Fouta Djallon. Two classified forests, located right next to each other separated by the river Gambie, were established in 1952, Woundou North and Woundou South (WCF 2012). Gadha Woundou does not have a designated IUCN category nor is it listed in the World Database on Protected Areas (UNEP-WCMC and IUCN 2018). The habitat is characterized by a mosaic of wooded savanna, savanna grassland, gallery forests and bamboo forests (WCF 2012). The presence of jackals (Canis sp.), leopards (Panthera pardus), green monkeys (Chlorocebus sabaeus), Guinea baboons (Papio papio), and patas monkeys (Erythrocebus patas) has also been confirmed (WCF 2012).

Ape status[edit]

In 1997, Rebecca Kormos conducted reconnaissance surveys in Gadha Woundou and confirmed the presence of western chimpanzees (Ham 1998). I.S. Camara surveyed Woundou North Classified Forest and estimated the chimpanzee population at more than 500 individuals (Camara 2007, report not in the public domain, details cited here were taken from WCF 2012). In 2011, the Wild Chimpanzee Foundation also surveyed Woundou North in collaboration with the Office for Biodiversity and Protected Areas Guinea (OGuiBDPA) (WCF 2012). They estimated that around 50 chimpanzees occur in the area, but noted that this was an underestimate because they encountered a group of 50 individuals while other survey teams noticed two additional chimpanzee groups (WCF 2012). In savanna mosaics chimpanzee nests are mainly found in gallery forests and a systematic survey design can lead to underestimations in such fragmented habitat (WCF 2012).

Threats[edit]

Around 5.600 people are living in proximity to Gadha Woundou (Camara 2007). Human density in Woundou North Classified Forest is low with seven villages around the site (WCF 2012). Roads to these villages are, however, not passable year round. A survey of anthropogenic signs found paths to be most prevalent, followed by slash and burn agriculture, traditional hunting and wood extraction (WCF 2012). Chimpanzees are not hunted and there were no signs of commercial hunting (WCF 2012).
