primer brin (
Juniperus communis
) [20], rešeljika
(
Prunus mahaleb
) [21] ter navadni ruj (
Cotinus
coggygria
) [18-19], ki je na tem območju izredno
pogost in učinkovito preprečuje presihanje
tal zaradi vetra in sonca ter tako pripomore k
ustvarjanju mikroklime, ki je primerna za rast
malega jesena (
Fraxinus ornus
) [22] in črnega
gabra (
Ostrya carpinifolia
) [23]. Trave so gostejše
v senci grmovja; ob puhastih hrastih (
Quercus
pubescens
) [24] se vegetacija razrašča v goščavo.
Vzdolž kraških suhozidov se razrašča grmišče
rdečega drena (
Cornus sanguinea subsp
.
hungarica
) [17], navadne kaline (
Ligustrum
vulgare
) ter poljskega bresta (
Ulmus minor
) ob
tipičnih elementih kraško–ilirske goščave.
Tu pa tam se ob značilni goščavi razprostirajo
površine, kjer raste črni bor (
Pinus
nigra) [16].
Umetna pogozditev predstavlja danes pomemben
element kraške pokrajine. Nenehna sečnja
gozdov, intenzivno pašništvo in pogosti požari so
od neolitika dalje postopoma spreminjali Kras v
golo in skalnato planoto; zato se je leta 1842 začel
izvajati program pogozdovanja s črnim borom:
slednji lahko namreč učinkovito pripravi tla
in ustvari rodovitno plast, primerno za sejanje
ali sajenje drugih rastlinskih vrst, značilnih za
to območje. Glede na to da je bor svojo nalogo
opravil, ga na Krasu zdaj selektivno redčijo, da bi
omogočili razrast avtohtonih listavcev.
F
or millennia the Karst was an excellent area
for grazing animals whose steady cropping
of the vegetation ensured the survival of the landa
carsica, the richest ecosystemof the Karst in
biodiversity terms. The economic changes that
took place in the years after the SecondWorldWar
led to the abandonment of nomadic grazing and
therefore to the spontaneous growth of scrubby
vegetation. The landa carsica has givenway to the
characteristic scrublandwhich is also found along
much of the Gemina trai
The abandoned pastures have been colonized by
shrubs such as juniper (
Juniperus communis
)
[20], St. Lucy’s cherry (
Prunus mahaleb
) [21] and
the Eurasian smokebush (
Cotinus coggygria
)
[18-19], the latter being the bush that ismost
frequently encountered in the area, a plant capable
of counteracting the drying of the soil caused by the
Bora and the sun and thus creating amicroclimate
suitable for germination of manna ash (
Fraxinus
ornus
) [22] and hop hornbeam (
Ostrya carpinifolia
)
[23]. Grasses spring up around the bushes,
exploiting the shade, and the vegetation evolves
towards scrublandwith the presence of downy oak
(
Quercus pubescens
) [24].
Strips of scrubwith species such as dogwood
(
Cornus sanguinea subsp
.
hungarica
) [17], common
privet (
Ligustrumvulgare
) and field elm (
Ulmus
minor
), mixedwith other species typical of karstic
and Illyrian scrub, develop along the drystone walls.
