It is first of all the favourable position that determines the great number of beauties of nature in the Tišnov region. From the orographic point of few the area is situated on the border of the Bohemian-Moravian Highlands and the Brno Highlands. The Bohemian.-Moravian Highlands are separated from the Brno Highlands by a wide stretch of lowlands called Boskovická brázda. The river Svratka, flows through the region in the north-southeast direction and rises in the area under the hill Žákova hora at the altitude of 750 metres above sea level.
The Tišnov region is also an important contact area as far as its geology is concerned. The northern and the western parts are occupied by the Bohemian-Moravian Highlands made up of crystalline slate and deep volcanic rock. In the east the Permian sediments of the lowlands Boskovická brázda separate it from the magma of the weathered Brno highlands.
At the same time the Tišnov region is an important contact point of two different types of flora. The forest flora of the northern Hercian-Sudeten region meets here the thermophilic steppe flora of the Pontitian-Panonian area. It is very interesting to see examples of the reciprocal penetration of the thermophilic plants to the northern sphere and vice versa the occurrence of the mountain species in the southern parts. Important migration roads of both plants and animals in the Tišnov region are the deep valleys of the Svratka river and its tributaries as well as the lowland region Boskovická brázda. This is where the thermophilic and steppe species wandered from the south to the north in the last ice age. These thermophilic species got acclimatized on the southern local hillsides. On the sunny hillsides of the hill Květnice there are the northernmost sheltered places in the Svratka valley that house the population of plants such as different sorts of feather grass (Stipa pulcherrima, Stipa capillata), meadow rue (Thalictrum minus), elecampe (Inula oculus-christi), hare-bell (Campanula bononiensis) and southern oak (Quercus pubescens). Another important thermophilic plant is the pasqueflower (Pulsatilla grandis) growing on the lime little hills between Kuřim and Tišnov.
The praying mantis represents the group of thermophilic animals (Mantis religiosa), the presence of which was detected in the Tišnov region for the first time at the beginning of the 1990’s. Some birds also depend on warm locations, such as the stonechat (Saxicola torquata) and the golden oriole (Oriolus oriolus). Some other species came from mountains to river valleys and to shady rocks facing the north. These plant species include for example club moss (Lycopodium annotinum), lunary (Lunaria rediviva), butterbur (Petasites albus), meadow rue (Thalictrum aquilegiifolium), snake root (Polygonum bistorta), oxlip (Primula elatior) and rhododendron (Rosa pendulina). One of the typical animals from the colder and higher altitudes is the mountain bird common nutcracker (Nucifraga caryocatactes).
The numerous habitats of the leaf-nosed bats (Rhinolophus hipposideros) and of some other bat species (Myotis) that have found suitable winter quarters in the underground karstic hollows in the hill Květnice, show the generic variety found in the Tišnov region.
Owing to its favourable location the Tišnov region constitutes a very precious type of countryside housing a varied mosaic of plant and animal populations. There are 10 nature reserves and 24 important protected nature sites proclaimed in the Tišnov region with the aim of an efficient protection of the biological variety and a controlled exploitation of natural resources. Four other protected nature parks reach into the Tišnov region from other neighbouring areas (Bílý potok, Baba, Podkomorské lesy, Svratecká hornatina).
