The Laßnitz is a river in Eastern Styria in Austria .

geography

The Laßnitz is a right tributary of the Rabnitz . It rises east of Graz in the municipality of Laßnitzhöhe and flows to the east through the municipalities of Nestelbach bei Graz (until 1958: area of ​​the municipality of Mitterlaßnitz) and Laßnitzthal . Subsequently, it forms the border between the communities Ludersdorf-Wilfersdorf (northwest) and Ungerdorf (southeast). The confluence with the Rabnitz lies on the southern border of the town of Gleisdorf .

The area is about 10 km east of the Mur in the west of the Eastern Styrian hill country .

The soils on the course of the Laßnitz are cheap arable land.

The most important tributary of the Laßnitz is the Nestelbach . This brook has its source in the village of the same name, Nestelbach, south of Laßnitzhöhe, is approx. 5 km long and flows into the Laßnitz in the municipality of Laßnitzthal at about 4.9 km.

The name of the river “Laßnitz” determined the naming of its catchment area: In addition to the municipalities of Laßnitzhöhe and Laßnitzthal, the towns of Oberlaßnitz, Laßnitzberg, Mitterlaßnitz, Mitterlaßnitzstraße and the cadastral municipality of Unterlaßnitz are located on it.

Its catchment area is opened up by the Styrian Ostbahn (Graz-Gleisdorf route with the Laßnitzhöhe and Laßnitzthal stations) and by the A 2 southern motorway (Laßnitzhöhe exit). The mouth of the Laßnitz is at the Gleisdorf Süd motorway junction. The motorway runs in the lower Laßnitz valley to the confluence of the Nestelbach and then follows this stream to the Laßnitzhöhe junction.

The catchment area of ​​the Laßnitz is loosely populated.

geology

The Laßnitz and its tributaries lie in the Styrian Tertiary Basin in gravel deposits called Schemmerl gravel (after the Schemmerlhöhe south of Nestelbach). These deposits are in the Pannon in Miocene ( Neogene dated), are therefore about 11 million to 7 million years old. As a geological level , this age corresponds to the Torton . The gravel is by its content of pebbles from limestone and vertebrate residues ( Vertebratenfaunen known). This layer is a river deposit in a south-easterly direction from the Alpine region north of Graz. These deposits form northwest-southeast-directed flat terrain back ( Riedel ) which the valleys of the major rivers (here Mur and Raab separate) from each other and on which the sources of the respective flows are as Laßnitz.

From its middle reaches the Laßnitz flows through the "Gleisdorf layers". These layers are fine sandy clays with gravel and coarse sand layers . They are approx. 12 million years old and come from the Sarmatian , whose deposits form the next older layer below the Pannon (see above). These are remnants of the deposits from an advance ( ingression ) of the Paratethys Sea into the East Styrian Basin. This “sea beach on the eastern edge of the Alps” was created in the course of the tectonic uplifts and subsidence during the final construction of the Alps and contains multiple shifts in the coastlines of this Miocene sea ​​at that time .

The subsoil of the Laßnitz catchment area forms gentle shapes.

The Laßnitz valley begins on the ridge between Graz and Gleisdorf . Top left the “plate” in the north of Graz (general map of Central Europe).

The gravel banks in the subsurface of the Laßnitz catchment area are several hundred meters thick. Below them - and thus roughly at the level of the Adriatic Sea - lie much older rocks: the "Wollsdorf Metabasite Formation", the age of which is dated to about 430 million years in the Silurian in the Old Paleozoic. This rock is exposed in the north of Graz on the "Platte". It belongs to the "Graz Paleozoic". This rock area was only slightly changed during the formation of the Alps (slight metamorphic overprinting), so that a largely complete sequence of very old rocks can be reconstructed.

environment

The Laßnitz flows through a sparsely populated area with forest zones and agricultural areas. Some of the settlements in their catchment area lie directly on the water.

Flora and fauna

There are still some hares and deer living in the area in larger wild animals . Due to the settlement, the associated traffic, including that of the railway line and the motorway, and because of the intensive agricultural use of the area, there are no large game populations.

The forests consist of mixed forest with beech , spruce and ash . The watercourses are lined with alders and willows .

Fruit crops in Nestelbach.

Water quality

The water quality is quality class I-II (almost unpolluted, in practice almost drinking water quality ). The neighboring farms and settlement can cause pollution.

The water hardness is due to the lime content of the ballast in the swelling area in the soft to medium hardness range.

Floors

Both on the slopes and in the valley floors, the soils are sedimentary brown soils that are well supplied with water . They form medium to high quality grass or arable land that can also be used for special crops such as fruit growing.

To the north of Nestelbach (GUX29) and on the Laßnitzberg north of Mitterlaßnitz (GUA10) there are soil protection points of the Styrian soil protection program. In Styria, the Soil and Plant Analysis Department of the Agricultural Experimental Center created a network of over 1000 examination sites in 1986-2006 to assess the degree of pollution of agricultural soils due to pollution, erosion and compaction Numerous parameters (general soil parameters, nutrients and pollutants) are continuously examined.

Surname

The name Laßnitz and its spelling variants such as "Lassnitz" etc. occurs several times in the south of Austria. It comes from Slavic and means a stream that comes from a forest or a cleared area (meadow, meadow, etc.), e.g. B. translated as "Waldbach", "Gereutbach", "Rodebach", "Wiesenbach" or Aubach These derivations are based on old forms of name. Possible references to the course of the brook in a cleared area also offer the derivations from “clearing, Gereut, clear spot in the forest” or from “near the damp meadows”.
