Chorbusch
Around 427 hectares of near-natural woodland on Cologne's north-western edge – a refuge for rare birds such as golden oriole and nightingale.
The Chorbusch is an extensive nature reserve on the far north-western edge of Cologne, adjoining the Knechtstedener Busch to the south. It is defined by a large, near-natural woodland of pedunculate oak and hornbeam growing on the sands and gravels of the left-bank Rhine lower terrace.

Setting & Landscape
The reserve is framed by several transport routes: the A 57 motorway and the Rhine run to the east, the B 477 to the west, the L 93 state road to the south and the B 59 to the south-west. Only the eastern section (Hausbusch), right next to Hackenbroich, is excluded. The ground is flat to gently undulating; on the terrace sands and gravels, mostly luvisols and cambisols have formed. Woodland, floodplain vegetation and a rural character shape the scenery.
The Woodland
At its heart lie large, well-developed pedunculate oak–hornbeam forests with pedunculate oak, sessile oak – here at its left-bank Rhine distribution limit – and hornbeam. The herb layer includes yellow archangel, greater stitchwort, wood millet, wood sorrel and lady fern. The most pristine part is the roughly 18-hectare natural forest cell "Am Sandweg" in the south-east, an old stand left entirely to nature. On smaller areas there are also melic and woodruff beech forests. Alongside these grow more managed stands of spruce, larch and red oak, as well as old poplar plantations that are already reverting to oak–hornbeam and alder–ash woodland. By area, hornbeam–oak mixed forest (around 130 ha), spruce and hornbeam woodland dominate.
Wildlife & Plants
The Chorbusch is an important habitat for birds: the critically endangered golden oriole and the nightingale are named explicitly in the conservation goals under the EU Birds Directive. They are joined by turtle dove, cuckoo, woodcock, red kite and long-eared owl, along with several woodpeckers – including black, middle spotted and lesser spotted woodpecker. Mammals include badger, fallow deer, brown hare and stoat, while wetter areas are home to alpine newt, common toad and common frog. The ground flora features characteristic species such as wood anemone, cuckoo pint, lily of the valley, herb Paris and small-leaved lime.
Protection & Significance
The area was designated to safeguard the functioning of the natural balance and to preserve a near-natural woodland as a habitat for threatened species. As part of the Natura 2000 site "Knechtstedener Wald mit Chorbusch", it also protects near-natural beech and oak–hornbeam forests as habitat for black woodpecker, middle spotted woodpecker and several bat species. Besides these ecological aims, the protection order expressly highlights the reserve's role as a large recreational area on the edge of Cologne.
