The stands’ regeneration through afforestation does not represent the main modality for insuring the stands’ regeneration, but it is used where the natural regeneration cannot be assured, and when the forests are extend or reintroduced. It may be appreciated that nowadays, the stand’s status is mainly influenced by the climatic, pedo­hydrological and anthropical factors .In this context, we may witness the process of devitalization and trees’ abnormal drying, especially in the arid areas of the country, respectively in the steppe and forest steppe regions, also in Danube meadow regions, in plane and other hilly territories, mainly during dry and extremely dry years. Statistics regarding the beating-up works and rehabilitation of affected plantations within the plantations realized between 2001-2010 by RNP-Romsilva reveal that there were established on a total surface ranged between 5621 and 9239 ha, and 18-25% were damaged and had to be remade. Concerning the supplying of forest reproductive materials, it may be mentioned that during 2001-2011 the seed stand and the seed orchard surfaces decreased, but the seed stands surface for the main scattered and other noble hard wood species increased. The ecological rehabilitation of the degraded forest is necessary and should be realized by promoting species more resistant to more and more dryer site conditions from forest steppe the plane forest and by extension of surfaces covered by Norway spruce in sub alpine region, Stone pine and Mountain pine in the alpine region. Related to the afforestation realized within the state owned forests, it may be noted that they were made in accordance with technical guidelines using the best genetically improved forest reproductive materials, with adapted provenances/ species in different site conditions. We consider that it is mandatory to update the technical guidelines in order to include a more intensive afforestation and forest management processes, conditions that are necessary for obtaining more stable and higher quality stands.
