Located in southeastern Liberia (between 5°–6°N and 8°–9°W), Sapo National Park is Liberia's first protected area and represents one of the most intact forest ecosystems of the country (Tweh et al. 2018). The area of the park was extended from 1,304 km² to 1,804 km² in 2003 (Tweh et al. 2018).

Located in southeastern Liberia, Sapo National Park is Liberia's first protected area and represents one of the most intact forest ecosystems of the country (Tweh et al. 2018). The area of the park was extended from 1,304 km² to 1,804 km² in 2003 (Tweh et al. 2018). The park forms part of the Upper Guinean Forest ecosystem, and contains high levels of biodiversity (N'Goran et al. 2010). The park is a low elevation tropical humid rainforest. Elevation in the southeastern area is approximately 100m with gently rolling hills while in the north, the elevation is approximately 400m in the north with steep ridges (Peal & Kranz 1990). In addition to the western chimpanzee, other endangered and vulnerable species inhabit the site, including forest elephants (''Loxodonta africana''), pygmy hippopotamus (''Hexaprotodon liberiensis''), Jentink’s duiker (''Cephalophus jentinki''), red colobus (''Piliocolobus badius''), and Diana monkeys (''Cercopithecus diana diana'', N'Goran 2010).

A survey in 1982 (one year before the establishment of the park), confirmed the presence of chimpanzees in the Sapo forest (Anderson et al. 1983). Based on the estimates from two surveys, one in 2009 (N'Goran et al. 2010) and a second one in 2017 (Tweh et al. 2018), the chimpanzee population in the park has remained relatively stable, with an estimated abundance of approximately 1,055 individuals.

Sapo National Park has been primarily threatened by illegal hunting and mining (Tweh et al. 2018; Greengrass 2016; N'Goran et al. 2010). An estimated 18,000 illegal miners were inhabiting the park in 2010, the majority of which was evicted by the government on the same year (Vogt 2011).

An estimated 18,000 illegal miners were inhabiting the park in 2010, the majority of which was evicted by the government on the same year (Vogt 2011). A survey of two commercial hunting camps bordering the park revealed high hunting pressure in the area, and the majority of bushmeat harvested was destined to urban areas (Greengrass 2015). The carcasses documented during this survey included chimpanzees as well as other endangered and vulnerable species, such as the red colobus monkey, Diana monkey, and pygmy hippopotamus. Furthermore, the development of the road network around the park is expected to increase hunting pressure and facilitate the bushmeat trade (Greengrass 2015), as well as other illegal activities in the park.

The national park forms part of the Tai-Grebo-Sapo Forest Complex, which is a conservation priority in West Africa. Conservation efforts in Sapo National Park have mainly focused on law enforcement, conservation awareness, and bio-monitoring. The WCF has supported Community Watch Teams (CWT), which comprise members from surrounding communities, and regulary patrol and support FDA rangers (WCF 2019). CWTs have played an important role in the eviction of illegal miners from the national park (WCF 2019). In 2012, Fauna & Flora International established a long-term bio-monitoring programme to follow the population trends for chimpanzees, pygmy hippotamuses, elephants, as well as duikers, birds, reptiles, and amphibians (Tweh et al. 2018). Together with Liberia's Forestry Development Authority, permanent transects are surveyed twice a year as part of this long-term bio-monitoring programme (Tweh et al. 2018).

The Forestry Development Authority of Liberia is responsible for the sustainable management of the forest sector and the protection of all natural resources. It runs the Sapo National Park in collaboration with Fauna & Flora International (FFI) and Wild Chimpanzee Foundation (WCF).  Main activities at the national park level include anti-poaching, conservation education awareness, and bio-monitoring & scientific research. As of 2019, the main activities in the research area have been camera trappings (2019,2020, 2021) by FFI and FDA in the entire national park. eDNA (focusing on Pygmy hippopotamus) was conducted in 2022. The national park forms part of the Tai-Grebo-Sapo Forest Complex, which is a conservation priority in West Africa. Conservation efforts in Sapo National Park have mainly focused on law enforcement, conservation awareness, and bio-monitoring. The WCF has supported Community Watch Teams (CWT), which comprise members from surrounding communities, and regularly patrol and support FDA rangers (WCF 2019).

Weak law enforcement has been cited as a major impediment (Greengrass 2016, N'Goran et al. 2010). As part of enforcing the protection of the park, the need to officially demarcate the buffer zone around the park has been stressed, as this area represents important habitat for chimpanzees (Tweh et al. 2018). Administrative weakness and lack of logistical and technical support have also been mentioned as challenges for Fauna & Flora International's long-term bio-monitoring programme (Waitkuwait 2003).  
+
The influx of local community dwellers inside the national park is hampering the SNP management to implement the protection of chimpanzees. Low manpower for conducting anti-poaching patrols in and outside the park has put chimpanzees under serious threat.
<br><br>
+
Very high illiteracy among the rangers thus making it difficult to collect data, process court procedures, and conduct conservation education awareness to local community people.

West Africa > Liberia > Sapo National Park

Summary[edit]

Loading map...
  • Western chimpanzees (Pan troglodytes verus) are present in Sapo National Park.
  • It has been estimated that 1,055 (CI: 595-1,870) individuals occur in the site.
  • The chimpanzee population trend is stable.
  • The park has a total size of 1,804 km².
  • Key threats to chimpanzees are poaching and illegal mining.
  • Conservation activities have focused on long-term bio-monitoring and law enforcement.
  • Sapo National Park is Liberia's first protected area, established in 1983.

Site characteristics[edit]

Located in southeastern Liberia, Sapo National Park is Liberia's first protected area and represents one of the most intact forest ecosystems of the country (Tweh et al. 2018). The area of the park was extended from 1,304 km² to 1,804 km² in 2003 (Tweh et al. 2018). The park forms part of the Upper Guinean Forest ecosystem, and contains high levels of biodiversity (N'Goran et al. 2010). The park is a low elevation tropical humid rainforest. Elevation in the southeastern area is approximately 100m with gently rolling hills while in the north, the elevation is approximately 400m in the north with steep ridges (Peal & Kranz 1990). In addition to the western chimpanzee, other endangered and vulnerable species inhabit the site, including forest elephants (Loxodonta africana), pygmy hippopotamus (Hexaprotodon liberiensis), Jentink’s duiker (Cephalophus jentinki), red colobus (Piliocolobus badius), and Diana monkeys (Cercopithecus diana diana, N'Goran 2010).

Ape status[edit]

A survey in 1982 (one year before the establishment of the park), confirmed the presence of chimpanzees in the Sapo forest (Anderson et al. 1983). Based on the estimates from two surveys, one in 2009 (N'Goran et al. 2010) and a second one in 2017 (Tweh et al. 2018), the chimpanzee population in the park has remained relatively stable, with an estimated abundance of approximately 1,055 individuals.

Threats[edit]

Sapo National Park has been primarily threatened by illegal hunting and mining (Tweh et al. 2018; Greengrass 2015; N'Goran et al. 2010). An estimated 18,000 illegal miners were inhabiting the park in 2010, the majority of which was evicted by the government on the same year (Vogt 2011). A survey of two commercial hunting camps bordering the park revealed high hunting pressure in the area, and the majority of bushmeat harvested was destined to urban areas (Greengrass 2015). The carcasses documented during this survey included chimpanzees as well as other endangered and vulnerable species, such as the red colobus monkey, Diana monkey, and pygmy hippopotamus. Furthermore, the development of the road network around the park is expected to increase hunting pressure and facilitate the bushmeat trade (Greengrass 2015), as well as other illegal activities in the park.

Conservation activities[edit]

The Forestry Development Authority of Liberia is responsible for the sustainable management of the forest sector and the protection of all natural resources. It runs the Sapo National Park in collaboration with Fauna & Flora International (FFI) and Wild Chimpanzee Foundation (WCF). Main activities at the national park level include anti-poaching, conservation education awareness, and bio-monitoring & scientific research. As of 2019, the main activities in the research area have been camera trappings (2019,2020, 2021) by FFI and FDA in the entire national park. eDNA (focusing on Pygmy hippopotamus) was conducted in 2022. The national park forms part of the Tai-Grebo-Sapo Forest Complex, which is a conservation priority in West Africa. Conservation efforts in Sapo National Park have mainly focused on law enforcement, conservation awareness, and bio-monitoring. The WCF has supported Community Watch Teams (CWT), which comprise members from surrounding communities, and regularly patrol and support FDA rangers (WCF 2019). CWTs have played an important role in the eviction of illegal miners from the national park (WCF 2019). In 2012, Fauna & Flora International established a long-term bio-monitoring program to follow the population trends for chimpanzees, pygmy hippopotamuses, elephants, as well as duikers, birds, reptiles, and amphibians (Tweh et al. 2018). Together with Liberia's Forestry Development Authority, permanent transects are surveyed twice a year as part of this long-term bio-monitoring program (Tweh et al. 2018).

Challenges[edit]

The influx of local community dwellers inside the national park is hampering the SNP management to implement the protection of chimpanzees. Low manpower for conducting anti-poaching patrols in and outside the park has put chimpanzees under serious threat. Very high illiteracy among the rangers thus making it difficult to collect data, process court procedures, and conduct conservation education awareness to local community people.

Research activities[edit]

Several surveys have been done in the park to monitor the chimpanzee population (e.g., N'Goran et al. 2010, Tweh et al. 2018), assess the impacts of conservation interventions (Tweh et al. 2018), investigate the behavior and ecology of chimpanzees in the park (Anderson et al. 1983), and investigate the impact of hunting pressure in the area (Greengrass 2015).
