A forest is a home of various mammals. Visitors may observe red squirrel (Sciurus vulgaris) as skillfully jumps from one branch to another. Squirrels might be rusty or dark brown color in Sulov. There are many of roe deers, red deers and wild boars in this area. On the contrary, the possibility that visitors observe our biggest wild cat – the Eurasian lynx (Lynx lynx), is very low. It moves extremely carefully around its territory, which can reach an area up to 30 square kilometers. It hunts mostly at night and at dusk. Also, the European hedgehog (Erinaceus europeus) comes out in the dark. It draws attention by rustling noises. Another nocturnal is a bat. It is a rare animal, however not so well known. In Sulov Rocks, these remarkable mammals hibernate in natural wintering grounds - in caves. The Lesser horseshoe bat (Rhinolophus hipposideros), which feeds on insects, is one of the critically endangered species.
