    <title language="eng">Opportunities and challenges of Black Locust (Robinia pseudoacacia L.) as a neophyte in temperate climate zones and potential approaches to management in the case of the urban area of Cleve, Germany.</title>
    <abstract language="eng">Black locust (Robinia pseudoacacia L.), a deciduous, nitrogen fixing tree of the family of the Fabaceae, can create opportunities as well as challenges in the areas it is found in. The gathering of information was done in three ways: 1) online research to gather basic information about the species, 2) communication with the Umweltbetriebe Kleve and the Niederrhein forestry office to obtain information about the situation in Cleve, Germany 3) visits to the different black locust stands to get an understanding of the situation. Black locust is a pioneer species with a short life span and is considered as an invasive neophyte in many European countries due to its strong suckering and ability to advance into habitats which then undergo an irreversible change in soil and species composition leading to biodiversity loss in especially threatened habitats such as dry grasslands. This is opposed by black locusts’ strong biomass production, making it well suited for plantation production, resulting in a strong, durable and fast growing multiuse wood as well as nutritious foliage which can be used as animal fodder or for the production of bioenergy. The 9 visited black locust stands situated in and around Cleve, Germany are well established middle-aged stands not used for the production of high value wood. These stands were considered as not threatening to their adjacent environments due to their being surrounded by streets, waterbodies and well maintained fields and parks making a spread unlikely. As the stands are quite old already letting them fade out by natural succession would be the recommended management method. Should the need for removal present itself, girdling would be the suggested technique as, even though it is quite time intensive, it is the least forceful method and thus minimises the possibility of a strong suckering reaction. In conclusion it can be said, that its usage and management system strongly depend on the location and closeness to threatened habitats, considering that, the environmental aspect should always be put before the economic benefits.</abstract>
