On the basis of the analysis of biotic and abiotic relations were earmarked the following ecologically important segments, which represent habitats sites with irreplaceable function in ecological stability and diversity of the contemporary country. They have pronounced biological protective, landscape and aesthetic value.

Ecologically important segments of the town greenery are characterised by individual park areas especially from the viewpoint of gardening value of taxa, dendrological specialities and aesthetic values.

The park areas encompass in the town 44,81 ha. They are larger or smaller areas of verdure in the residential area, in the central part of the city. The composition of the tree species is varied, indigenous kinds prevail up to 90%. In the centre of the town there are small parks, which are part of city conservation. On the fringe of the town there are larger park areas with natural character.

Public verdure covers in the city more than 479,16 ha. It fulfils mostly protective and hygienic functions.

Area 2 ha. An important amphibian refugium in the suburban zone. An occurrence of Triturus vulgaris, Triturus cristatus, Bufo bufo and other animals was described. The location is suitable for study purposes of species and interspecies relations.

Area 4 ha. The shrubby and tree escape covert in agricultural land creates a mini area of rich species diversity of bird fauna.

Area 0,05 ha. An enclave of wet terrain depression. In herbal undergrowth dominate the following species Scirpus sylvatica, Juncus sp., Veronica beccabunga, and other ones. At the surrounding meadow xerotherm habitat an appearance of rare taxa of family Orchidaceae was noticed.
