nutrient-rich,
alkaline
pH.
Require land not too
clayey and with
high water table.

fast
growing species.
It is able to fix the
heavy metals present
in the soil.
Phytodegradation
action for different

Prunus avium
Fertile well drained
but never very dry
soils, with pH close
to neutrality.
Mesophilic areas, it
grows well in the
undergrowth of oak
thermophilic woods
if the soils are
adequate.
Conducive to animal
biodiversity.
Fast growing species.

Indifferent to soil
type.
Heliophilous,
xerophilous
and
thermophilic species.
It is widespread in
the range of holm and
thermophilic oaks.
Species with good
naturalistic
functionality
recommended
for
environmental
restoration.
It favours the presence
of birds useful in the
biological control of
potentially
harmful
insects.
Quercus
frainetto
It adapts to all land,
however, preferring
those fresh, fertile
and deep, with
acidic pH or sub
acid. It shuns those
very calcareous.

Italy in the range of
Quercus
cerris
woods.
Biodiversity
protection.
It is a species
