Sažetak
The unmanned aerial vehicles (drones) are helpful equipment in the habitat and species mapping. Drones equipped with multispectral cameras can provide acquisition of scenes with resolution of less than a centimeter. The use of common (visible spectrum) camera that most of the drones are equipped with, could be useful in mapping of places that are difficult to reach by a researcher. It has been noted on several occasions that mapping habitat types in a specific (flowering, senescence etc.) phenophase of either dominant or differential species could significantly enhance the accuracy of habitat mapping. This method was implemented in the mapping of the habitat type 5330 Thermo- Mediterranean and pre-desert scrub (on islands Sušac, Palagruža, Jabuka, Dugi otok, Kornati, Lastovo and Iž) and 1420 Mediterranean and thermo- Atlantic halophilous scrubs (Sarcocornetea fruticosi) on the Mirna River mouth and on island Zeče, and was shown useful for mapping this type of habitat. In the summer of 2021, the usefulness of drone was tested in the survey of different type of habitat, calcareous rocky slopes with chasmophytic vegetation in Istria. The identification and mapping of species in such vertically distributed habitats could be problematic because high resolution image is required to detect all necessary details for plant identification. Additionally, following technical problems are detected: need for very precise piloting skills, change of wind speed on different parts of the cliffs, problems with finding take off place and place for piloting, as well as problem with parallax if the take off (starting) point is remote from the observed object.
