Photointerpretation of archival orthophoto of the Poličnik area

In the last few decades, overgrowing of farm land has been observed on the area of Poličnik (Zadar, Croatia). Favourable climatic conditions and the geographic position are of paramount importance for the agriculture and economy. Mapping vegetation possibility using traditional methods is unlikely due to the size of the surface itself, the available human resources, but also the dangers of field research. Thus, the research carried out on the basis of remote sensing is more favourable than traditional methods. The habitats mapping was carried out using remote sensing method of archival and recent orthophoto. This research sought to determine the intensity of the succession stage in the period from 1952 to 2013. In all three locations of research (marks: 4048, 4050 and 4052) forest areas increased, especially at the mark 4050 for as much as 0.91 km² or 25.7% of total of 3.6 km² surface area. Surfaces covered with maquis shrubland were in deficit precisely because of the degradation stage of the maquis shrubland transitioning into forest. The biggest change was at the location 4048 where the surface covered with maquis shrubland decreased by as much as 0.53 km², that is, by 15.93% of the total area. The most significant change in terms of the increase of the areas covered in grasslands was at the location 4048 where it amounted to 0.42 km² (10% of the total area). The results correspond to the hypothesis about increasing succession precisely because of anthropogenic factors.
