By the geographical division of flora along Slovakia, the vegetative area around Piešťany belongs into the part of north Carpathian flora. There are two major types of trees – deciduous and coniferous. On south slopes of Carpathian Mountains grow dry deciduous oak woods with large variety of small plants – flowers and grasses. Near river Váh grow willows, poplars and alders. Very important is also water basin Sĺňava, which is officially named to be protected study area because there grow few plants in danger of extinction. E.g. Centaurium pulchellum, Linum austriacum, Sagittaria sagittifolia, Schrophularia umbrosa – which are also registered in list of all rare and endangered plants. The fauna around Piešťany is highly representated by animals typical for steppes and forest-steppes. In the basin, on the edges of forests live wild rabbits, hares, pheasants, partridges (because of high consumption of pesticides is their number decreasing). Feeded and hunted animals are mainly – in forests – stags, roebucks, boars, mufflons, sometimes wild cats or foxes. Parks and park-forests in Piešťany have very good conditions for life of birds.
