Résumé

Understanding wildlife behavioural responses to the anthropogenic variables is paramount to address human-wildlife interactions issues and promoting conservation in human-dominated landscapes. This study, conducted in 2019, focused on a troop of chacma baboons (Papio ursinus) named Madiba’s troop which inhabits George Nelson Mandela University campus situated in the Garden route in South Africa. This region faced a fire in October 2018 that burnt 86000ha impacting the campus by burning mostly pine plantation. Our objective was to understand the fire's impact on Madiba's troop behaviour. We recorded baboon movements to estimate home range size, troop dispersion and any urban foraging events (UFE) where troop members tried to entered houses or open any 2018 (before fire). The shock experienced by Madiba’s troop led to the departure of half of the troop whereas new individuals incorporated it leading to a troop being half the size as before fire. The fire burnt 32% of the home range and led to the arrival of another troop reducing Madiba’s home range by 53%. Consequently, troop members stayed mainly on campus to rely on anthropogenic food and performed as much UFE as before fire. Surprisingly, burnt pine plantation represented 28% of their new home range and troop members visited more pine plantation than natural forest. This result can be explained by the cut of the standing pines leading to an easy access to pine nuts. Even if the troop reduced its home range, it was more scattered than before fire, decreasing the number of participants in an UFE and thus the risk to be detected but still caused important damages. Such environmental change in fragmented landscapes increased pressure on urban areas by the troop worsening perception of baboons by people.
