Grassland botany
Grassland botany is a branch of grassland management that deals with the botanical aspects primarily of permanent grassland ( meadows and pastures that are at least five years old ).
More than half of the plant species in Europe are found in the "land use form grassland " (in broader terms). Due to the high biodiversity (up to 70 plant species per 25 m² reference area and a multiple of fauna taxa , e.g. arthropods ), grassland botany plays a major role in nature conservation issues , but also in landscape aesthetics. This high biodiversity is achieved through periodic or episodic lighting of the lower vegetation layers.
Problems such as intensification of use , fertilization , use of liquid manure , silage , mowing time of first growth or other topics of this ecosystem are answered here taking into account geobotanical and landscape-ecological issues and not from economic approaches.
Grassland botanical institutes exist in Germany in Freising and Göttingen , Kiel and Bonn, among others .
