Analysis of the floristic elements
The analysis of the floristic elements mark out the
dominant euro Asiatic elements, which among those
central European sum up approximately 82 species
(70%) from the reserve flora, forming more than half the
floral elements which means that they constitute the
floristic background of this reserve.
Mediterranean and Ponto Mediterranean floristic
elements, which are thermophile species found especially
on the sunny slopes, form together 8%. However, the
cosmopolitic species are also remarkable, representing
5% from the total species found in the reserve.
The fact that the reserve in situated in sloppy area is
confirmed by the presence of the circumpolar and even
alpine European at the reserve level, together
representing 7% of the total species (Fig.4).

Humidity
If we group the plants by their humidity regimen in
which they are adjust to live here, we will discover that
the most dominant are xeromesophilic (U2-U2,5) which
65
are 42% from the total of the identified species in the
reserve, these being found in the droughtiest places,
specially on the meadows.
Notable are also the mesophilic (U3-U3,5) which have
a percentage of 37%, and can be found in areas where the
light is scarce or there is an excess in humidity, where the
swamps dry up during the summer but nevertheless have an
excess in moisture.
The xerophilic (U1-U1,5) can be found in 5% and this
shows the hot and arid summer climate, being especially
noticed on the slopes that have a south exposure, covered
with a small seam of clay soil.
In a percentage of 6%, the mesophilical (U4-U4,5)
species that prefer soils from humid to moist-wet, are found
near lakes or where there is an excess in moisture all year
long.
Remarkable is the presence of the hydrophilic (U5-
U5,5) and ultrahydrophilic (U6) species which together
form 5% from the total of species, and can be found in the
ponds or on their border where water is present all year
round.
The amphytoletant (U0) species can also be found in
the reserve in a percentage of 6%, being the most adaptable
for these special conditions (Fig.5).

Temperature
Mesothermal (T3-T3,5) appear in a percentage of
63%. Mild thermophilic (T4-T4,5) species appear in a
percentage of 12%, which suggests that the climate in the
reserve in a temperate-continental one.The
amphylotolerant (T0) appear in 16% of the total.
The cryophilic (T1) species are missing, and the
microthermal (T5) species appear in a small percentage,
only 1% (Fig.6).
