The Pleiser Hügelland , more commonly known under the name Pleiser Ländchen , is a hilly landscape up to a good 235  m high in southern North Rhine-Westphalia in the Rhein-Sieg district and in the east of the city of Bonn , which extends the up to 461  m high Siebengebirge to the north and northeast as well the nearby around 300  m reach Lower Westerwald to the northwest abdacht. Flowed through by the Pleisbach and Hanfbach , it meets the valley of the Sieg in the north and the valley of the Rhine in the northwest with its partial landscape Ennert .

The Pleiser Ländchen, apart from the wooded Ennert ridge, is mainly used for arable farming.

Natural classification

The north-west adjoining valley of the Rhine and the valley of the Sieg to directly above Hennef , which adjoins it in the west, are already partial landscapes of the Cologne Bay (main unit 551), the Middle Siegtal (330.1) above Hennef is part of the Mittelieg-Bergland (main unit 330 ) and the Asbacher plateau (324.80) adjoining it to the southeast is part of the Niederwesterwald (324).

geology

The sunken deeply through, pointing to the northwest Box valleys of hemp and Pleisbach and their tributary streams embossed Pleiser hills with loess , loess loam and tuffs covered. Besides playing bench gravel and tertiary sands and clays a certain role. This structure is interrupted by occasional basalt breakthroughs. In and around the Ennert part of the landscape, lignite mining with alum extraction was carried out intensively between 1809 and 1875.

places

The Pleiser Ländchen is located in its north-west in the Bonn district of Beuel and takes the districts of Hoholz , Holtorf (with Oberholtorf, Niederholtorf and Ungarten) and Holzlar (with Kohlkaul, Roleber, Gielgen and Heidebergen) with the Ennert .

The majority of the Pleiser Ländchen is in the Rhein-Sieg district and there in its southwest in the northeast of the city of Königswinter and in its northeast in the southwest of the city of Hennef and in the southeast of the city of Sankt Augustin .

In addition to the urban area of ​​Bonn and the transition to the Siegtal, the districts of Königswinter Thomasberg and (on the Ölberg ) Ittenbach in the south, on the edge of the Siebengebirge, and on the other side of the A3 Oberpleis are more densely populated .

In the northeast, the valley of the Adscheider Baches is part of the NSG Ahrenbachtal and Adscheider Tal , which extends to the north of the Asbach plateau. Smaller nature reserves are the NSG Eisbachtal with shallow depths at Oberpleis, the "NSG Pleisbach" (SU-100) and to the north the "NSG Rotter Hardt and Morbach" (SU-103), in the south and west the edge areas of the Pleis hill country also belong to the core area of ​​the 1922 formed "NSG Siebengebirge".
