The BUCF Herbarium stores 253 specimens of allochthonous oaks species belonging to 33 accepted taxa. Amongst the representatives, Quercus rubra has the most recordings. Moreover, three species classed as near threatened on the IUCN Red List were identified. The most significant contribution was made by the botanist S. Pașcovschi who amassed approximately one-third of the collection. The specimens were collected between 1872 and 1987, with a maximum activity between 1940 and 1949. The majority of the specimens were sampled from dendrological parks and botanical gardens in Romania, the Bazos Dendrological Park remarking itself with one of the most diverse collections of cultivated oaks. A considerable number of specimens were received from donations and exchanges with several herbaria. Most of the herbarium material is very well-preserved having high potential for future investigations.

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-Hîrlău 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.
