characteristics
Benefits
Notes
Acer campestre
Soil variables as pH
and texture; adapted
to clay soils.
Heliophilous species,
able to withstand the
drought season.
Long-lived species of
easy rooting.
Low potential for
ozone formation.
Low
degree
of
allergenicity of pollen.
Acer
monspessulanus
Soil variables as pH
and texture; adapted
to clay soils.
More
thermophilic
than
Acer campestre
.
Long-lived species of
easy rooting.
Low potential for
ozone formation.
Low
degree
of
allergenicity of pollen.
Alnus glutinosa
Soils with high
water table.
Typical species of
alluvial areas.
Resistant to pollution.
It promotes the quality
of the soil and air by
means of nitrogen-
fixing
bacteria
(
Frankia alni).
High degree of
allergenicity.
Cercis
siliquastrum
It’s adapted to poor
soils and arid.
Heliophilous
and
xerophile.
Resistant to pollution.
Celtis australis
Prefers stony, basic
and well drained
soils. Optimal pH
7,0-8,0.
Pioneer
species
resistant to drought.
It can be used in
ruderal areas.
Important for wildlife.
Resistant to pollution.
Ficus carica
It prefers loose or
stony soils and does
not tolerate those
too compact or with
stagnant water
Rustic
species
without
special
needs, however, is
sensitive
to
temperatures < 8°
that can kill the entire
plant.
Resistant to pollution.
Suitable
for
the
establishment of noise
barriers.
Fraxinus ornus
Undemanding, It’s
adapted to basic
stone or clay barren
lands.
Thermophilic
and
xerophile
species
able to colonize
rocky places.
Good
ability
to
engraftment of post -
agricultural
soils.
Pollen is pleasing to
Apoidea.
Low potential for
ozone formation.
Suitable
for
the
creation of noise
barriers.
Degree
of
allergenicity
moderate to high.
Malus sylvestris
Fertile and never
very arid soils with
pH close to neutral.
Temperate species, in
the
Mediterranean
areas like mesophilic
stands with good
water availability in
summer.
It promotes animal
biodiversity.
Populus alba
Indifferent to the pH
It needs of a large
supply of water.
Hygrophilous
fast
growing species.
It colonizes quickly
damp
surfaces
producing new shoots
from the roots. Effect
of phytoextraction and
phytostabilization of
pollutants such Zn,
It is potentially
subject
to
collapses. It is
employed
in
environmental
recovery and bio-
energetic purpose.
