Video: See the daring relocation of a silverback gorilla

June 2010: The solitary silverback gorilla Mukunda had been ravaging the crops of local villagers living around Virunga's Gorilla Sector in the Democratic Republic of Congo for two months. Rangers began starting to fear for his life, as his systematic crop-raiding destroyed the livelihoods of the local communities who depend upon their agricultural produce to survive.

The rangers had to take action to get Mukunda - who had strayed over 5km from the forest in search of maize and bananas - back to the park.

Watch this video to see the daring intervention by rangers and the gorilla doctors to re-locate Mukunda back to the forest.

It was an eventful day. In a process that took about five hours from start to finish, Mukunda was anaesthetised before being carried to the road, where he was loaded into a 4x4 which drove him back to his home in the forest. The gorilla doctors succeeded in anaesthetising 175-kilo Mukunda in extremely challenging circumstances. The Rangers coordinated the entire effort efficiently and effectively to ensure Mukunda's safety, who made his final bit of the journey on a bamboo stretcher.
