A proposal to expand the Tadoba Andhari Tiger Reserve (TATR) by an additional 1,100 sq km from the current 625.40 sq km has been sent to the Maharashtra. "We have proposed to include another 1,100 sq km to TATR which has about 45 big cats and at least 12 to 14 cubs. Once the new area is added, TATR will become an ideal habitat for tigers," S P Thakre, Conservator of Forest and field director, TATR told PTI.
