Urban land use types contribute to grassland conservation: The example of Berlin

摘要: Abstract Urbanisation is an important driver of biodiversity loss, also contributing to habitat loss and fragmentation grasslands at the urban-rural interface. While urban green spaces are known include many grassland habitats, it uncertain what extent land use types harbour special conservation interest whether patch characteristics connectivity these differ from on agricultural land. By relating city-wide biotope mapping Berlin, Germany, we assessed (1) which specific major belong, (2) differences in connectivity, (3) value patches a typological level by means their legal protection status. Grasslands cover 5% Berlin's surface, 43% that area assigned legally protected types. The majority (71%) lies opposed 29% Airports historic parks, only 2% contain one-third all dry grasslands. Wet more confined In airports areas, larger but complex shape than those parks. airports, show greater as they situated grassland-dominated surroundings. Grassland parks appears be vulnerable due smaller sizes higher fragmentation. example Berlin demonstrates infrastructure can clearly contribute may thus partially compensate for decline traditional cultural landscapes. It will involve residents landowners management because most (57%) was found outside areas.
