Conservation culture

from Wikipedia, the free encyclopedia
Two conservation cultures in the Botanical Garden of the City of Frankfurt am Main: Wild form of real celery (in the foreground). In the background: the lancet-leaved bellflower ( Campanula baumgartenii )

As a maintenance culture is of botanists a group of individuals of a plant type or a plant subspecies designated, the outside of their site of origin (ex situ) cultured is. This cultivation usually takes place in a botanical garden with the aim of preventing the local, regional or global extinction of a wild species that is endangered in its natural location (in situ). The population taken in conservation culture can therefore usually be assigned to a known place of origin.

Conservation cultures can help reintroduce a species that has become extinct in its natural habitat. Conservation cultures can lead to genetic erosion (i.e. a decrease in genetic diversity; genetic bottleneck ) of the cultured occurrence. Therefore, the populations must be carefully collected for inclusion in the culture and unconscious selection must be avoided in the culture and a sufficiently large number of individuals must be kept available.
