In April, 2012, the Maharashtra state government issued a notification adding 60 km2 (23 sq mi) to the old 61.1 km2 (23.6 sq mi) area of Bor Sanctuary. The new Core Zone of 115.92 km2 (44.76 sq mi) is the most protected and inviolate part of the sanctuary where the public is not allowed. It comprises 95.7% of the total area. Most of the core area is contiguous with good forest of Wardha Forest Division and Nagpur Forest Division. The Eco-tourism Zone of 5.21 km2 (2.01 sq mi) designated for public access for nature and wildlife tourism comprises 4.3% of the total sanctuary area. The purpose of the tourism zone is to educate the public about the significance of nature and wildlife conservation and to stimulate their environmental awareness. The Buffer Zone is less protected forest area near the sanctuary that serves as a protective barrier for the core area. The Bor Tiger Reserve is physically divided by the Bor Reservoir into 2 sections, previously; 2/3 (40 km2 (15 sq mi)), as the west part and 1/3 (21 km2 (8.1 sq mi)), as the eastern part. 95% of the western part is in Wardha district and 90% of the eastern part is in Nagpur district. The Bor Reservoir area is about 7.25 km2 (2.80 sq mi) and is not included in the total sanctuary area.
