The Asian Elephant (Elephas maximus) is listed as endangered in the IUCN Red list as the wild population has declined by at least 50% since the 1930s. Massive deforestation, developmental activities, increased human population has destroyed the age-old corridors of elephants in Asia in general and in Assam in specific. This ‘corridor’ plays a vital role in maintaining population viability across a larger landscape. We reassessed three designated elephant corridors and identified a new corridor to map the present status in Tinsukia district of Assam using ground-based survey and geospatial tools. Detail of the land use pattern and land cover status, risk zones, disturbance factors along the corridors, its buffer area, length, and connectivity of the corridors have been mapped. The land use and land cover change along the corridor show that there is a substantial increase of human settlement, tea gardens, and agricultural land in the corridors and creating disturbances in the free movement of elephants from one habitat to another. The study will help monitor changes in corridors over time in the study area.
