- Abstract
Weedy-ruderal species Ambrosia artemisiifolia L. (fam. Asteraceae) is in the phase of fast and intensive spread on the territory of the Republic of Serbia, to which it has been introduced from the neighboring European countries. It belongs to adventive floristic element and it is believed that it was introduced into Europe in 1800 from North and Middle America together with contaminated clover seed (Priszter, 1960). On the territory of Vojvodina, the northern part of the Republic of Serbia it was found on the banks of the river Danube, near Petrovaradin, Sremski Karlovci and Novi Sad, as well as near Bogojevo, Odtaci, Bač and Bačka Palanka. It has been spreading northwards near Kula, Begeč and Futog in the region of Bačka, as well as in central and south Banat. As problem of adventive and invasive weeds is not of local character and that spread of such species is determined quite late, when they already become problematic, terrain monitoring, as well as exchange of information between stations that monitor these processes are important. Studies performed in the period 2008-2010 on over 400 ha of non/agricultural and ruderal areas on the territory of the city of Novi Sad, A. artemisiifolia was determined on over 200 locations. Studies were carried over on uncultivated and green areas, and for mapping and distribution of the species, modified method of Brauen-Blanquet (1951) was used. For data processing the specially designed software program Ambrosia Spot Marker (Konstantinovic et al, 2008) was used. During growing season, monitoring of this species was performed because it?s spatial spread, as well as the occurrence of retro vegetation after mowing or chemical control. During the period of studies, Ragweed is found in over 200 locations in 21 urban areas of Novi Sad. Mapping, determination of abundance and coverage of this invasive species during vegetation period from April to October in the three-year study, showed that the highest number of A. artemisiifolia was 50 plants per m². For each city area maps were made in the program Ambrosia Spot Marker.
