Habitat
Situated inside a loop of the River Po, Isola
Boscone is rather like a huge green lung within a landscape of
cultivated farmland and poplar trees, typical of the Lombardy Plain.
Centuries of erosion have changed the course of the river and in recent
years embankments have been built, creating a peninsula. Thanks to
intervention by LIPU, Isola Boscone has escaped the destruction which
has affected such a large part of the floodplain, so that it has
retained its natural heritage of trees and animals. Consequently, it is
on the list of Nature Reserves of the Lombardy Region and recognised as
a "wetland of international importance" under the terms of the
Ramsar Convention. Its main elements are the great wood of white willows
and areas of mud, resulting from the river flowing only very slowly and,
in places, leaving stagnant pools. For several years there has been an
active programme of reforestation to supplement the dominant tree
species with other species which are also characteristic of the Lombardy
Plain, such as oak, maple, black alder and white poplar, as well as
various bushes and shrubs, including hawthorn and elder.

Birds
A great river, bordered by areas of shallow and
stagnant water, and dense, green, peaceful woodland: Isola Boscone is
very attractive to large numbers of many different species of birds. A
relaxing walk along shady woodland paths allows one to see many small
birds, from acrobatic Great Tits to the more shy Spotted Flycatchers,
from Bluetits to Long-tailed Tits, from Chaffinches to Robins, just to
mention a few. Holes in trees reveal the presence of Green Woodpeckers
and of Greater Spotted Woodpeckers, whose drumming often re-echoes
through the wood. From time to time a silent shape glides across some
clearing, and we discover a Long-eared Owl or the rarer Short-eared Owl,
and perhaps, over the gravely river bed, a Black Kite or an elegant and
powerful Osprey, here only present during the migration period. Amongst
the high meadow grass, in spring, one comes across families of
pheasants, now permanent residents of the Reserve and breeding freely
here in safety from human hunters. Elsewhere there are important areas
for waders to rest and feed and here Common Sandpipers, Greenshanks,
Redshanks, Black-tailed Godwits, Snipe and Black-winged Stilts are the
species which are most likely to be encountered during the course of the
year. In winter, on the other hand, there are ducks and other water
birds, such as Teal, Mallard and Pochard, as well as Cormorants and
Great Crested Grebe. The river, and its sandbanks and embankments, are
also a haven for other birds whose lives are linked closely to water:
Kingfishers, Common Terns, a few breeding pairs of Little Terns, and
occasional Black Storks and Spoonbills. But the Boscone Reserve is,
above all, a place for herons. On the edge of the reserve there is a
heronry of over 600 pairs of Night Herons and Little Egrets, of
international importance for both species. At the end of summer there is
always the spectacular sight of tens, and sometimes hundreds of egrets
and herons fishing, or the huge silhouettes of Grey Herons flying into
the sunset.
