Wildlife corridors are areas, such as nature preserves, overpasses and underpasses, that connect habitats that humans have separated. These areas act as safe spaces for all sorts of animals to move around, including elephants. And yet, according to a study in Frontiers in Conservation, human activities seriously affect animals’ use of these spaces. Assessing these effects for the first time, this study shows that elephants cross wildlife corridors according to their perceptions of varying human threats.
