Analyzing soil seed bank of invasive species in soil in nature protected area

The aim of this research was to determinate the number from invasive weed seeds in two protected areas. Soil sampling was carried out in north of Serbia Landscape of Outstanding Features Nature Park ‘’Palić’’and Nature Reserve ‘’Ludaško jezero’’. The depth at which samples were taken in each location was 0-10 cm. Weed seed bank from these two areas contained seeds of: Lolium multiflorum, Amaranthus retroflexus, Celtis occidentalis, Galinsoga parviflora, Vicia articulata, Setaria italica, Datura stramonium, Asclepias syriaca, Matricaria discoidea, Portulacae olaraceae, Veronica persica, Iva xanthifolia and Echinochloa crus-galli. Amaranthus retroflexus, Celtis occidentalis, Portulaca oleracea and Setaria italic were determinated in very large numbers at each protected location. The sampling of soil was done at two locations, with a probe of the same volume. Identifying the seeds and determining their quantity was carried out with microscopes and determiners
