Abstract

Among the arboreal and shrubby weeds colonizing non-crop environments in the ApuliaRegion (Italy), Ailanthus altissima (Mill.) Swingle (Tree of Haven), an exotic invasive fastgrowing species, is one of the worse. Its management is very difficult because of its fast growthand root-sucker's production, and mechanical and chemical treatments provide only shorttermcontrol. Within a research program on the management of woody weeds, impact ofA. altissima was assessed in the wide urban area of Bari and in the Alta Murgia National Park.During numerous inspections distribution was determined by mapping all plants with GPS;their size, number and density were estimated. All damages were noted down. In Bari, datawere recorded along a 76 Km path, with 146 areas of plants surveyed (most with medium-highdensity) and 584 single plants measured; in the Park around 126 Km of roads were mapped,with a total of 92 areas surveyed and 130 single plants measured. Compared with otherarboreal and shrubby weeds, in Bari A. altissima proved to be the most widespread species; inthe Park it is highly threatening the ecological equilibrium of the environment. Its distributionin the studied areas confirms its ability to colonize strongly disturbed, marginal, or naturalundisturbed environments. Moreover, within the project, different methods for micro injectionof systemic herbicides into trunks were developed and tested, to combine the effectiveness ofthe herbicides at reduced rates with the safety for non target organisms and environment. Theresults of mapping and tests will be presented.
