Threats
Table 3. Threats to apes reported for Afi River Forest Reserve
Category | Specific threats | Threat level | Description | Year of threat |
---|---|---|---|---|
2 Agriculture & aquaculture | 2.1.2 Small-holder farming | High (more than 70% of population affected) | From a survey done in 2008, 244 farms were observed. Farm sizes varied ranging from as small as 15 m² to as large as ten hectares (Imong & Wood 2008). | 2008-Ongoing (2024) |
4 Transportation & service corridors | 4.1 Roads & railroads | High (more than 70% of population affected) | Transportation and service corridors in some of the areas of the reserve have been seen. It is slow but with significant deterioration (BirdLife International. 2024). The Ikom-Obudu highway passes through the Afi River Forest Reserve that acts as a corridor connecting Mbe Mountain and Afi Mountain Wildlife Sanctuary (Obeten et al. 2024). | Ongoing (2024) |
5 Biological resource use | 5.1 Hunting & collecting terrestrial animals | Medium (30-70% of population affected) | Hunting signs were recorded at 0.66 per km in a survey done in 2008. Few hunting trails and hunters were encountered during the survey. The reasons given that could explain the few encounters could be that levels of wildlife abundance is so low, and that hunting was done mostly at night when the survey team did not collect data (Imong & Wood 2008). Despite the numerous conservation efforts in the Afi, Mbe, and Okwango areas poaching activities are still being done because the income made from poaching is much better than the alternative provided for hunters (Abere et al. 2016). | 2008-Ongoing (2016) |
5 Biological resource use | 5.3 Logging & wood harvesting | High (more than 70% of population affected) | Evidence of past and ongoing logging was encountered throughout one of the surveys conducted. A total of 3,671 pieces of timber were counted during the survey (Imong & Wood 2008)
Reporters visited in August 2021 and observed several trucks loading logged timber day and night in and near ARFR. Due to the high demand for timber products especially in urban areas, deforestation has ravaged many areas of the reserve (Orji, S. 2021). |
2008-Ongoing (2021) |
7 Natural system modifications | 7.1 Fire & fire suppression | High (more than 70% of population affected) | Large areas have been subject to dry-season bush fires, including a severe one in 1989 (BirdLife International. 2024). In 2021 ARFR experienced fires according to data that was provided by NASA. This was the highest fire activity in years (Orji, S. 2021). | 1989, 2002, 2021 |
8 Invasive & other problematic species, genes & diseases | 8.4 Pathogens | Low (up to 30% of population affected) | With humans, domesticated animals and gorillas living close together due to encroachment, there is a high risk of pathogens and parasites spreading to the gorillas. The small size of the Cross River gorilla populations makes them extremely vulnerable to the effects of introduced pathogens, and virulent infections could effectively eliminate them (Oates et.al 2007). | Ongoing (2007) |
Conservation activities
Table 4. Conservation activities reported for Afi River Forest Reserve
Category | Specific activity | Description | Implementing organization(s) | Year of activity |
---|---|---|---|---|
2 Counter-wildlife crime | 2.3 Conduct regular anti-poaching patrols | They do patrols but they haven't been as effective due to lack of sufficient funding for rangers that ought to be on patrols and lack of mobility (vehicles to conduct these patrols effectively). There is no great support from the government either (Orji, S. 2021). | Cross River State Forestry Commission | Ongoing (2021) |
4 Education & awareness | 4.1 Educate local communities about apes and sustainable use | WCS implements conservation education activities to control the forest behavior of people in the communities in the cross-river state. Evaluation (Obeten et al. 2024) has shown that the more environmental awareness is for the community, the more they tend to promote forest conservation. | WCS Nigeria | Ongoing (2024) |
5 Protection & restoration | 5.10 Use prescribed burning within the context of home range size and use | The government and NGOs have implemented measures to reduce logging and restrict bush burning in rural communities (Obeten et al. 2024). | Cross River Government and WCS Nigeria | Ongoing (2024) |
