Download he ecological succession in wetlands

Nature reserve of Fondotoce
• The Fondotoce Special Nature Reserve on
a surface of 365 hectares, stretches out on
the final section of the Toce River.
• The protected area is the last bastion of
the wetlands. It has an high level of
biodiversity.
• The most popular enviroment in the nature
is the reed bed. The Common reed is the
ideal ecosystem for its numerous lake fish
to reproduce and for some 100 bird
species
•
The importance of the reed
bed is also due to its
fundamental function as a
“green filter”. The reed
absorb numerous pollutants
thus contributing to purifying
the water. As for the flora,
there are different types of
willows, two rare ferns only
found in wetlands and rich
aquatic vegetation. The
Reserve is a shelter for over
200 species of birds.
Endemic species of water
chestnut Trapanatans
verbanensis.
The ecological succession in wetlands
Ecological succession is the gradual and orderly process of change in an ecosystem caused
by the progressive replacement of one community by another until a stable climax is
established

The rushes

The rushes marks the passage beetwen
water and land, the rushes host a great
variety of animal species: among around
25 species of fishes, 200 species of birds
and caracteristic species of plants: the
reeds

It can grow in damp ground, in standing
water up to 1 metre or so deep, or even
as a floating mat.
the reed plants grow in areas with hot
summers and fertile growing conditions.
They have been used to make arrows.
The elastic structure of the plant can
act as a great wood structure. In many
European countries Reeds have been
used extensively for many centuries in
the construction of thatched roofs.
THE
SHRUBS
•
•
The shrubs are small trees growing to 10
meter tall usually multistemmed, with an
irregular, often leaning crown.
Untily the 60s the willows of this areas
has been cutted to obtain flexible ties for
vines and vegetables gardens
SALIX TRIANDRA or ALMOND WILLOW
SALIX ALBA or WHITE WILLOW
THE
RIPARIAN WOODS
•
•
The riparian woods forms along the banks of
watercourses. In these periodically flooded
areas, white willow is prevalent, togheter
with poplars and alders.
Today this wood is left to its natural
evolution: dead plants are not removed
since they constitute an important stage in
the life cycle of the wood.
