FORESTRY BELTS SILVICULTURE AND CINEGETICS REVIEW XVII/30/2012 4. Conclusions Consequently, in order to set up the forest shelterbelts network at the level of the two main geographical units (totalizing 87212 ha and protecting a 3486947 ha area of agricultural land) a quantity of 436000000 seedlings is required. Even if the value has an orientation character (safe estimation) so far and is due to be finalised within the feasibility study stages and technical project, this is useful for the dimensioning and scheduling the production capacity of the afforestation stock. Taking into consideration the very large area subject to the afforestation work, the highly scattered character of works, and the very large quantity of afforestation stock which is required to be produced, such work is appreciated to be scheduled on a minimum 10 year period of time. Considering the above mentioned values regarding the area of the shelterbelts network, the total quantity of required seedlings, as well as this minimum time period for producing the afforestation stock, and for carrying out the work, it results the fact that the production of necessary afforestation seedlings can be finalized on a nursery surface of approximately 145 ha, that has to be available at least one year before the start of the setup works and has to be distributed relatively uniform at the level of the 19 involved county, proportionally with the shelterbelt area corresponding to each county. Accordingly, for producing the afforestation stock required by the setup of the forest shelterbelt network for field protection, the nursery area required at the county level has an average of approximately 7.6 ha.

FORESTRY BELTS SILVICULTURE AND CINEGETICS REVIEW XVII/30/2012 Abstract Although its long tradition in Romania, the activity of setting up forest shelterbelts has been neglected in the last four decades, due to circumstantial situations. By the Law no. 289 (May, 2002) concerning the establishments of forest shelterbelts, some premises have been created for a national system of forest shelterbelts to protect the agricultural lands in the areas frequently affected by drought. The present paper addresses the aspect of designing the forest shelterbelts, starting with the location compulsory information and thus from the main factors that depend the location or the distribution of the forest shelterbelts on a certain area, determine the basic elements necessary to establish these protective cultivations: orientation, distance, width and the shelterbelts openings. The paper presents a brief characterization of specific ecological site conditions of two geographical units, because the distribution and the combination way of ecological site conditions factors within the Romanian Plain and Dobrogea determine the afforestation diversity solutions recommended for the establishment of forest shelterbelts. Regarding the installation of forest filed shelterbelts, the present paper sets the ecological site conditions on which the shelterbelts are required (using systematic review of ecological forest sites in the Romanian Plain and Dobrogea) and recommends the tree and shrub species that can be included in the forest shelterbelts composition, the main features of forest shelterbelts (field location, orientation, width, distances, recommended species, planting drawing) and the afforestation solutions in the existent ecological site and soil conditions. The paper main objectives aimed on the theoretical location of the field forest shelterbelts network in the Romanian Plain and Dobrogea, the settlement of the compulsory forest shelterbelts and the location of that network by land use categories (arable or pasture) and the estimation of the seedling stock needed to achieve these shelterbelts. The resulting information are useful for sizing and for timing of the afforestation stock production and they presently have only a background character at the regional level. Key words: forest shelterbelts network, crops protection, ecological site conditions, afforestation compositions. Translated by: Roxana Gabriela Munteanu 60
