Wildlife corridors are areas of habitat that connect separate areas of similar habitat and allow animal movement and gene flow between populations. They are important for maintaining biodiversity as they help counteract the effects of habitat loss and fragmentation. Effective corridors should be wide and maintain natural vegetation and habitat. They enable species migration and support genetic diversity. Management aims to enhance habitat quality and protect ecological processes within corridors. The Siju-Rewak Corridor in India links two protected areas and preserves an important elephant crossing point along the Simsang River.
