Sažetak
An essential basis of the natural resources of the Telašćica Nature Park on Dugi otok is the existing vegetation, which with its diversity determines the diversity of the existing biocenoses, i.e. the overall biological diversity. This biodiversity can be damaged, considering that in the last fifty years, a rapid spread of the invasive alien species of Ailanthus altissima (Mill.) Swingle has been observed in the area of the ecological network in the Telašćica Nature Park. Therefore, field research was carried out in 2023 to determine the number of female trees based on the presence of flowers/fruits. The number of trees with a girth less than and more than 20 cm, the height and diameter of the tree and the extrapolated number of female trees for the entire area were also made. The collected GPS coordinates of the species distribution were transferred to the QGIS geographic information system, where the analyzes were carried out. The average density of occurrence of individuals is 0.66/m2, while the density of occurrence of female individuals is 0.023/m2. Given that these are the first studies, these results can serve as a baseline for future monitoring of the spread of the invasive alien species A. altissima in the area of Dugi otok.
