Environment

  

Lędziny administrative area is located within two micro regions - Silesian Upland and Raciborsko-Oświęcimska Basin. On the Silesian Upland , which is characterized with logging landscape, we can distinguish part of southern slope of Murcek Plateau descending in the direction of Mleczna Basin and divided with depression near Ławki, together with Przyrwy Valley. From the south-east it is limited with Lędziński Prominence, stretching between Hołdunow and Jaroszowice, which is 5 kilometers long and about 1,5 kilometers wide. Its highest parts, reaching over 300 meters above sea level, are rolling or hilly, in some places shallow valleys can be found. More gentle south-eastern slopes of the Prominence descend in the direction of Vistula Valley and Przemsza Valley, including also Gostynia Valley being a part of Oświęcimska Basin.

 

In terms of physiography, Lędziny is located in the area of Jaworznickie Hills, on the terrain varied with hills: Klimont (302 meters above sea level), Szachta (296 meters above sea level), Strzyżówka (290 meters above sea level), Małkowiec, Kępa, Wapieńka, Glinonogóra.

 

The area located within Silesian Upland is geologically built mainly with Trias, Cambrian and Quaternary deposits. The bottom of Mleczna Basin is lined with Miocene and Pleistocene deposits. The units which are included in Oświęcimska Basin are built with Miocene loams, sandstones and slatestones covered with Quaternary sands and loams and also with boulder clays and sands, which result from the activity of glaciers.

 

The climate of Lędziny town area is shaped with subtropical air masses - coming from the South through Moravian Gateway, arctic and polar air masses - coming from the North, maritime air masses - coming from Atlantic and continental air masses - from Eastern Europe.

 

Soil cover of the municipality is not varied. There are mainly podsolic soils, that were created from glacial deposits, brown soils, chernozem, (appearing mainly on highlands of Lędziński Prominence) and boggy soils. All soils that can be found on Lędziny area were classified as "A", that means that they are the least contaminated, where plants may be grown without any limits. The main crops are: different types of spring and winter grains, corn, potatoes and sugar beets.

 

In the Lędziny area there are two water flows: Goławiecki Creak and Przyrwa river belonging to Vistula catchment area. Przyrwa river, constituting the tributary of Mleczna river, is about 15 kilometers long, with its sources in Wesoła, almost the whole part of the river within the town boarders is regulated. In the past it created many meanders within broad, flat and marsh valley. At the bottom of Lędziński Prominence, there is the source of Goławiecki Creak , which flows in the broad, marsh valley located in lower parts of the town, with its outlet in Vistula. This creak is used for fish farming in many ponds situated near it. Both rivers are fed with many smaller flows, which usually do not have names.

 

Natural landscape dominates on large parts of the municipality, comprising 76% of the town area, where field-arable suptype predominates, constituting 38,5% of the area. In Lędziny area usable landscape also may be found, which consists of urbanized and mining-industrial landscape, which was created as a result of anthropogenic activity. Central, south-eastern and north-eastern parts are particularly urbanized.

 

Northern and north-eastern part of the municipality is surrounded by forests, being a part of forest protective zone of Górnośląski Industrial District. Coniferous forests dominates and in the second place there are mixed forests, mainly pine-oak forests. They fulfill very important protective function - they stop most of the pollutions coming to Lędziny area from more industrialized parts of Silesian area.
