Plant health of these species is inappropriate:
- All species present valley inclines, even resinous
anchored by pickets, due to padding ground
movement;
- Rare 3-4 m hight pine, planted before this study, has
dyied in proportion of approx. 90%, due to adaptation
problems typical for plantations with large seedlings
(grown in special nurseries under controlled
conditions of humidity) transplanted in very difficult
conditions (in hot summer, in open field without
shelter, without daily watering etc.); moreover this
species of acidic soil does not correspond to the
carbonated soils;
- Rare 3-4 m hight Norway spruce planted in 2009 has
dried only in proportion of approx. 10%, but its
keeping is not certain, the needles are slightly wilted
in March 2010, partially covered by black deposits (of
uncertain origin, probably before planting because it is
not present in other species); it still requires special
attention (especially by maintaining soil moisture at
an optimum level), because spruce do not preffer
hydromorphic or compact carbonated soils.
- The small to medium deciduous species are more
resistant to planting, so it is expected that they will
better survive; in March 2010, being out of the
growing season, seedlings provide little indication of
of their health status.
7. Description of the stationary
The ground waves are graded as "Regions of hills of
the sessile oak and common oak subareas
"stationary group GS 139 - embankment slopes
consisting of mixtures of soil and rock, with sandyloamy
to clay texture and variable content of skeleton
(MAPPM, 2000 - technical standards for
composition,schemes, and technology of forest
regeneration and afforestation of degraded land).
On the waves of ground from Stupini erosion
manifests itself as drops of water from rainfall and
water runoff on slopes.
The classification by classes of degradation
(Miulescu, Tăbăcaru, 1963), they fall in the
moderatesecond degree erosion (E2), with rare
runoffs, cracks and with superficial landslides.
The relatively small surface of the ground waves, the
mosaic character of the soils used as fillers, the
manifestation on reduced surfaces of runoffs and
