Ape status

Chimpanzees are extinct or nearly extinct in Ala Forest Reserve. During a 2006 survey, no chimpanzees, nor signs of chimpanzees, were encountered (Greengrass 2006).


Threats

The northern half of the reserve is dominated by teak, oil palm, and cocoa plantations (Greengrass 2006). In the southern half of the reserve, even though the forest seems to be in a better condition, logging pressure is very high and large mammals are very scarce (Greengrass 2006).

Category Specific threats Threat level Description Year of threat
1 Residential & commercial development Unknown
2 Agriculture & aquaculture 2.1 Annual & perennial non-timber crops High Oil palm and cocoa plantations in the northern half of the reserve (Greengrass 2006) Ongoing (2006)
2.2 Wood & pulp plantations High Land cleared for teak plantations (Greengrass 2006) Ongoing (2006)

Conservation activities

Table 4. Conservation activities in Ala Forest Reserve

Category Specific activity Description Implementing organization(s) Year of activity
1 Development impact mitigation 1.3 Prohibit (livestock) farmers from entering protected areas Farmers and all unauthorised people are not allowed to enter into the reserve by intensive patrols within the area (Ofori-Amanfo pers. obs. 2023). Ongoing (2023)
1 Development impact mitigation 1.4 Farm more intensively and effectively in selected areas and spare more natural land Old cocoa and rubber farms are being cleared (since 2016) to plant new hybrid to yield more products to increase farmers income rather than clearing more land for cultivation (Ofori-Amanfo pers. obs. 2023). Ongoing (2023)
2 Counter-wildlife crime 2.3 Conduct regular anti-poaching patrols Field staff undertake day patrols, over night patrols and long/sleeping patrols in the Park to control poaching and for field data collection (Ofori-Amanfo pers. obs. 2023). Ongoing (2023)
2 Counter-wildlife crime 2.8 Provide training to anti-poaching ranger patrols Staff are trained in, how take field data on animals and how to manage the animal species causing human animals conflict and others (Ofori-Amanfo pers. obs. 2023). Ongoing (2023)
4 Education & awareness 4.1 Educate local communities about apes and sustainable use Local communities are educated on the need to conserve the resources in the Park since the 1990s (Ofori-Amanfo pers. obs. 2023). Ongoing (2023)
5 Protection & restoration 5.2 Legally protect ape habitat Ongoing
