Ruderal area
A ruderal area (from the Latin rudus , “lump”, “chunks” and in the figurative sense “gravel”, “gravel”, “rubble”) is a mostly fallow raw soil area . It can be of natural origin, for example caused by landslides , rock falls, or it can be found on gravel banks and gravel surfaces of rivers and glaciers; Such raw soil locations are rare in man-made landscapes. But there are also ruderal areas of hemerobic (human) origin on areas no longer used by humans , on stony demolition sites or on urban rubble debris or rubble heaps from the Second World War.
The wilderness of a ruderal area reveals its special features on a small scale, often hidden. It houses a very special community of plants ( ruderal flora ), animals and fungi , so-called pioneer species . This area is an important habitat for these animal and plant species .
