Ruderalfläche
Ruderalflora
A ruderal surface (from Latin rudus, lumps, 'chunks' and, in the transposed sense, gravel, 'gravel', 'rubble') is a roughly lying raw soil surface. It can be of natural origin, caused, for example, by landslides, rubble falls, or is found on pebbles and gravel surfaces of rivers and glaciers; in the man-cultivated landscape such raw soil sites are rare. But also hemerobes (human) origin, there are rowing surfaces on areas no longer used by humans, on stone-bearing abatement grounds or on urban rubble rubble or ruins from the Second World War.
The wilderness of a rowing area reveals its peculiarity in the small, often hidden. It houses a very special lifebloom of plants (rudal alfora) and animals, so-called pioneer species. For these animal and plant species, this terrain is an important habitat. Weblinks Edit sourcetext
