No other deciduous tree is discussed so much controversely than black locust regarding their silvicultural importance and their ecological risks. German nature conservation authorities classify the species as invasive while foresters label it conditional invasive. The impact of black locust on the site conditions is fundamental: nitrogen fixation, a high potential for reproduction and expansion combined with the ability to drive out other species. On the other site, foresters appreciate the tree species due to their growth (also in short rotations) and their outstanding wood quality. A general evaluation is not sufficient due to the potential for conflicts regarding about 22.500 ha of black locust in Brandenburg. The main goal of the research project is the evaluation of the invader potential of black locust for high nature value areas. The results should be used for management strategies of black locust stands in accordance with nature protection. This includes the appraisal whether action should be taken to force back black locust in some cases and which minimum distance between black locust stands and sensible biotopes are required. As a fist step areas at risk are localised and quantifies based on distances between black locust stands and nature conservation areas. At some selected sensible biotopes, vegetative and generative expansion of black locust is mapped and reconstructed. Vegetation and soil chemistry are investigated to monitor and evaluation the impact of black locust at the sites. Further, the inhibitory effect of adjacend forest stands will be investigated.
