69. Indigenous species used for new outdoor planting

On Campsites alien species are very popular because of their attractiveness and strong growth. More and more of these alien species establish, distribute uncontrollably through pollen, imbrute, hybridize and finally are not distinguishable from indigenous species. An ecological reasonable planting though includes indigenous vegetation. These are species, that display a certain adaptation to a particular area and also emerged in that same place. This can also include bred forms of species and ones that were imported over centuries (Middle Ages) ago and adapted successfully to the local environment.
