“…Yet others have reported the unpredictable nature of the time of day baboons' crop-raid (e.g. Biquand et al, 1992). Farmers in GGNP generally reported that baboons raided when people were absent (unpublished data), and it was thought that Gamgam group would opportunistically forage in fields when farmers were absent.…”

Crop-raiding Baboons (Papio anubis) and Defensive Farmers: A West African perspective

Baboons are often reported as the worst crop-raiders in Africa, but there has been little observation of the actual behavioural-ecology of their crop-raiding, especially in West Africa. The paper examines the crop-raiding behaviour of a group of habituated baboons (Gamgam group) near the village of Gashaka on the south-western border of Gashaka Gumti National Park, Nigeria. Data were collected during the wet and dry crop seasons via scan sampling and ad libitum techniques. For scan sampling the activity of each observed individual was noted every 2.5 min. For ad libitum data any activity relevant to crop-raiding was noted when it occurred, including the reactions of farmers who were guarding their fields. Descriptive statistics were generated and trends in baboon and human behaviour examined. Sixty-nine percent of Gamgam group's raids were successful. Farmers only prevented or reduced the time baboons spent in fields on 28.9% of all raids. Crops eaten varied from ripe maize to scavenging for scraps of sweet potato in harvested fields. Maize (ripe and dried) was the most frequently eaten crop. All members of Gamgam group, including weaned infants, ate all crops, but only adult males ate bananas. Observations suggested that baboons used cheek pouches to store food before moving to a safer locality to eat, to avoid farmers' attacks and intragroup competition. Deterrent methods included guarding, fences of fish net, poisoned baits, olfactory, visual and auditory scaring devices. Guarding presence in fields was not regular. In the wet season guards reacted to baboon crop-raiding on 54% of raids and in the dry season on 44%. On average it took farmers 23 min to react to baboons in their fields. The two most common reactions of guards were shouting and chasing baboons. Observations do not suggest that any one particular defence method can prevent baboon crop-raiding.

“…However, we included the best available data and a search of the published literature aided the selection of environmental variables employed. There was a large interspecies variation in habitat mean annual rainfall across the genus, [32][33][34][35] thus suggesting some differentiation among Papio species. Rainfall indirectly affects plant productivity and species richness and thus food availability, [35][36][37][38][39] consequently foraging and ranging patterns, and indirectly distribution, are affected.…”

We assessed the human impact on regions identified as the environmental central niche for the chacma baboon(Papio ursinus) across southern Africa. This central niche is the area within an animal’s natural range that is most insulated from changes to the environmental variables that influence that animal’s distribution. We used an environmental envelope model constructed with geographic information system software to predict the geographic extent of the central niche. The predicted chacma baboon central niche was 389 000 km2, with substantial overlap with human settlements in several countries. Of note is that although Botswana contains nearly 60 000 km2 of predicted central niche, the International Union for the Conservation of Nature chacma baboon distribution map implies that much of this area is uninhabited by baboons. A regional assessment of the province of KwaZulu-Natal (South Africa) suggests more than 95% of its central niche is uninhabited. Additionally, the very limited and likely disturbed central niche area in Lesotho coupled with the unknown status of chacma baboons within Lesotho warrants further attention. Overall, it appears likely that significant proportions of the predicted central niche in southern Africa are currently uninhabited by the chacma baboon. These uninhabited areas correspond with areas of high human population density and anthropogenic land alteration. The remaining central niche areas that are still inhabited are potentially key areas for conservation and are important for ensuring the sustainability of future populations. However, these areas may be undergoing degradation whilst also becoming more inaccessible to baboons, thus increasing the difficulty of conservation efforts. This preliminary assessment highlights the urgent need for detailed assessments at a finer scale.

“…For example hamadryas in Awash National Park, Ethiopia were known to occasionally raid crops both outside and within the park (Nagel 1973). Raiders and commensal baboons account for 35% of the entire estimated Arabian hamadryas population (Biquand et al 1992). Crop raiders in agricultural areas were much more common than were commensal groups (Biquand et al 1992).…”

“…In fact, the Hamadryas Baboon is the only nonhuman primate species to inhabit the Arabian Peninsula. In Saudi Arabia, hamadryas are found along the Sarawat mountains which run parallel to the west coast of the Arabian Peninsula and the Red Sea (Biquand et al 1992).…”
