"Red-tailed monkeys' movements to and from the cocoa plantation, were facilitated by close proximity to the forest and by trees planted as wind-breaks and for shade," the researchers write.

"Solitary males caused damage to crops that was intensive and thorough, perhaps because they had more time to spend in the plantation due to the lack of co-operative activities they had to engage in, compared to individuals living in social groups," the authors note.
The authors recommend planting tea around a cocoa crop to keep out social groups, as red-tailed monkeys disdain tea. But they write that such methods may do little to keep out males.
"If solitary raiders, which are secretive, cause proportionally more damage, greater time and vigilance will be required for farmers to guard against this threat," they write adding that controlling crop raiders is an important step to facilitate a better relationship between local farmers and conservation areas in the region.
