Your writer chose the 'scare' name instead of the more descriptive "habitat dividing" fence. Habitats are divided by many events, human activity and natural activity. Results are not always destructive. For instance, evolution often takes different paths--produces greater variety--when habitats are divided. Pathogens might also kept on one side or the other. Same for invasive species. Same for poachers. Plenty of habitat exists on both sides of the fence for the species you name to maintain viable populations. If they do or not, depends not on the fence but on the people and their governments on each side. Any article on environmental change that mentions only bad results, is usually a propaganda piece and its writer erodes his or her own credibility and the credibility whatever relevant facts might also be recorded.
