Madhya Pradesh (MP), the central Indian state is well-renowned for reptile fauna. In particular, Pachmarhi Biosphere Reserve (PBR) regions (Districts Hoshangabad, Betul and Chindwara) of MP comprises a vast range of reptiles, especially herpetofauna yet unexplored from the conservation point of view. Earlier inventory herpetofaunal study conducted in 2005 at MP and Chhattisgarh (CG) reported 6 snake families included 39 species. After this preliminary report, no literature existing regarding snake diversity of this region. This situation incited us to update the snake diversity of PBR regions. From 2010 to 2012, we conducted a detailed field study and recorded 31 species of 6 snake families (Boidae, Colubridae, Elapidae, Typhlopidea, Uropeltidae, and Viperidae) in Hoshanagbad District (Satpura Tiger Reserve) and PBR regions. Besides, we found the occurrence of Boiga forsteni and Coelognatus helena monticollaris (Colubridae), which was not previously reported in PBR region. Among the recorded, 9 species were Lower Risk – least concerned (LR-lc), 20 were of Lower Risk – near threatened (LR-nt), 1 is Endangered (EN) and 1 is vulnerable (VU) according to International Union for Conservation of Nature (IUCN) status. Hence, there is an urgent need for strategies to conserve these rare and threatened snakes in PBR.
