Evaluation of the Invasive Potential of Black Locust (Robinia Pseudoacacia) in Brandenburg


No other deciduous tree is assessed as controversially as the North American Robinia in terms of its future forestry significance and ecological risks. Key factors are the influence of nitrogen fixation on the site, a high reproduction and propagation potential and the ability to displace other species. On the other hand, from a forestry perspective, the tree species is valued for its growth performance, also in short rotation, and its special wood characteristics. A blanket evaluation does not do justice to the conflict potential for the approximately 22,500 ha of Robinia stands in Brandenburg. The central aim of the research project is to assess the risk of invasive potential of the Robinia for valuable areas from a nature conservation point of view. Due to neighbourhood relations between Robinia populations and protected areas, risk areas are to be localized and quantified first of all on a state wide basis. The vegetative and generative spread of the tree species will be mapped and reconstructed on a subset of nature conservation sensitive areas. Investigations of the ground vegetation and soil chemistry will record and evaluate possible changes. The results of the investigations will be used to develop management strategies for the nature conservation compliant management of Robinia stands.
