In addition to the fragmentation of natural areas
and decrease of biodiversity, another relevant problem is the
effacement of the wetlands, riverine stands, regulation of water
streams. Drying up of the town verdure areas is caused by
canalisation of the precipitation, and this way comes about almost
100% outflow from the built-up areas in the town.
Another problem is strong, up to extremely strong
potential erosion on the deforested areas, especially in the north
and north-west part of the town.
