Protected areas pose a major interest in the current context in which natural habitats are very fragmented as a result of economic development. The ROSCI0076 Dealul Mare-Hârlău site represents the largest protected area from Moldova’s Plateau where forest habitats occupy a majority surface. A total number of 10 Natura 2000 forest habitats were identified on the site’s surface. Among them, the majority are 91Y0 - Dacian oak hornbeam forests and 9130 - Asperulo-Fagetum beech forests. These are comprised of 79% natural forests, while planted forests represent 19%. The main age ranges between 40 and 80 years, with compact areas with young forests, as well as with forests older than 100 years. Forest habitats are stable from an ecological point of view, ensuring optimum conditions for the development and colonization of species presented on the site’s map.
