The area covered by the network, its percentage and
the total protected area within the arable land use
category, on the three solution types, is the following
(Table 4):
Table 4. Arable land – area covered by the network of forest shelterbelts, on solution types
Solution type Network area - ha Total area - ha %
I 3.915,2717 156.450,0458 2,50
II 9.301,5302 372.673,1402 2,50
III 1.781,2027 70.986,2658 2,51
Within the permanent pastures land use category, the
distribution of the area of shelterbelt network at the
county level reflects a variation ranging from 800 ha
(Tulcea) up to 1190 ha (Constanţa).
Within the arable land land use category the
distribution of the area of forest shelterbelt network at
the county level reflects a variation ranging from
under 4600 ha (Tulcea) up to above 10400 ha
(Constanţa).
From the distribution of the forest shelterbelt network
by counties, localities and land use categories, in the
Danube Plain and Dobrogea, it can be noticed the fact
that in the Danube Plain, in case of arable land use
category, the localities with the largest network areas
are Perişoru (443 ha) and Dragalina (398 ha) in
Călăraşi county. In Dobrogea, within the same land
use category, the localities with the largest network
area are Casimcea (357 ha) in Tulcea county, and
Cobadin (322 ha) in Constanţa county.
In case of pasture land use category, in the Danube
Plain, the localities with the largest network area are
Smârdan (65 ha) in Galaţi county, and Ianca (26 ha) in
Brăila county. In Dobrogea, within the same land use
category the localities having the largest network area
are Lipniţa (84 ha) in Constanţa county, and Cerna (76
ha) in Tulcea county.
3.3. Establishing the necessary seedling stock for
setting up the forest shelterbelts in order to adjust
the production capacity of the afforestation stock
and its phasing
Given data obtained relating to the areas covered with
forest shelterbelts up to detail level, as well as the data
regarding the shelterbelts characteristics (composition,
schemas and densities) were used to assess the
necessary afforestation stock on solution types,
totalized and differentiated by species, both at a local
level and at county ones, presented in a table form.
Danube Plain
In the Danube Plain resulted a total number of
351128600 seedlings required to establish the network
of forest shelterbelts, of which the basic species
(greyish oak) represents almost 40%. The
differentiation of this total required of seedlings by the
two land use categories is as follows: arable land –
336828468 seedlings (of which the basic species
represents approximately 40%); permanent pastures –
14300131 seedlings (of which the main species
represents approximately 40%).
The total number of seedlings necessary for setting up
the network of shelterbelts within the permanent
pasture land use, on the five solution types, is the
following (Table 5):

types

VIII 591.751 236.700
The total number of seedlings required to establish the
network of shelterbelts within the arable land use
category, by the five solution types, is the following
