The extended World Heritage property is proposed to carry the joint new name: "Primeval Beech Forests of the Carpathians and Other Regions of Europe". Supported by 13 European countries (Romania included), the nomination proposes to establish a transnational serial UNESCO property, with a surface of more that 95000 ha, that reunites the most representative and well preserved beech forests from the natural areal of this species in order to illustrate the ecological process of extension-that is in progress at present-of beech on the European continent. The process of choosing these canditate sites was thought for completing the existent sites and for providing arguments and reflecting better on the extension of species distribution at the level of Europe. At the end of January 2016, Austria, the coordinator country of the nomination process at the international level transmitted the common dossier for the nomination to the committee of evaluation of UN-ESCO World Heritage List.

The effect of the proportion of sessile oak in the stand composition on specific patterns was also studied. Comparable with other natural forests, the stands of Runcu-Grosi are characterised by a high volume (mean living tree volume of 577 m 3 ha À1 in the sessile oak dominated plots and 675 in the pure beech plots), a highly differentiated diameter distribution and a large quantity of dead wood, especially in the mixed plots (approx. 135 m 3 ha À1 , compared to 75 in the pure beech plots). The higher volume of coarse woody debris in the mixed plots is due to the higher proportion of dead sessile oak in the reserve, which accounted for about 70% of the total dead wood in both the sessile oak and the beech dominated plots. The over proportional representation of dead sessile oak, and a very low number of oak saplings taller than 1.3 m, indicated a declining tendency of sessile oak in the stand in future. The sessile oak dominated stands exhibited a higher level of tree species diversity than those dominated by beech. Where beech was the dominant species, a high percentage of the sessile oak was present in pure groups (36%), whereas in the oak dominated stands, most of the sessile oaks were surrounded either by shade tolerant beech or by other species (ca. 75%), and were classed as either dominant or codominant trees. These species-specific patterns correspond with the silviculture of mixed oak-beech forests: without interventions to favour oak, the dominance of beech will increase.
