The presence of poachers and illegal agriculture has caused the population of savanna elephants at Virunga National Park in the Democratic Republic of Congo to dwindle. But park rangers have secured the area from militia and poachers and established successful initiatives with the local community.
Now 580 savanna elephants have returned to the area, raising the total number to at least 700. The returning elephants have reverted the landscape to grassland — the way it was 50 years ago — by uprooting trees and trampling invasive bushes. And it's resulted in the return of other wildlife, too.
