Forestry research involves difficulties because it is largely on the field and less in the laboratory. Because of this, forest monitoring has been carried out quite hard, with a fairly low accuracy and their duration was rather high. Along with the development of aeronautical, batteries and cameras technologies, unmanned aerial vehicles (UAVs) have emerged, which are used in agriculture and construction, and in recent years they have also been adopted in the forestry domain. Today, the use of drones in forestry is reduced to forest surveillance, fire detection, identification of flora and fauna, but their potential is much higher. Researches on the state of forest health have been carried out in an improvement area planted in the 1980s to stop soil erosion, using both modern techniques (drone overflight, GIS techniques) and traditional monitoring (soil level observations, sample shedding and laboratory determinations). From the results obtained from the processing of data collected with the drone flight and validated using soil level observations and laboratory analyzes, it results that the forest in the improvement area is attacked by fungus Lophodermium pinastri.
