The southern course of the river Adda develops among alluvial deposits. The most ancient terraces, dating back to the Holocene period, are the farthest ones from the riverbed, while the most recent ones slowly degrade towards the river course. The protected territory includes, besides the coastal territory, also marshlands consisting of "oxbows" and "dead branches" which the river formed in time while changing its course; some very interesting examples for their geomorphological, botanical, and zoological meaning, are Adda Morta, (an old branch of the river, in the Municipalities of Castiglione d'Adda and Formigara), Zerbaglia (wetland of national interest in the Municipalities of Turano, Cavenago d'Adda and Credera Rubbiano) and Morta di Soltarico (forming after the 1976 flood).
The Park territory consists of a first stretch of about 5,000 hectares
including the agricultural-forest flood plains, in particular those
lands situated at the lower inner areas of the river which can be
subject to floods, both with overflow waters and with resurgence.
The Park is focusing its efforts for a recovery of the hydrogeological consolidation and a quantitative and qualitative reconstruction of natural environment and landscape.
The second and the third stretches include a large Park area covering about 18,000 hectares of fertile countryside both on the shores of Lodi and Crema - Cremona.
It is characterized by woodlands, wetlands, and river beaches.
"Woodlands along the rivers are usually ecosystems which have been
subject to a few changes, and therefore represent an ideal biotope for
many vegetable species" (D.Yon 1982).
The natural features of lentic wetlands have been well preserved, and among them also the minor watercourses of naturalistic interest have been classified.
The cultivated landscape represents another important aspect of the Park, even if these lands have suffered from a progressive deterioration deriving from wrong management methods. Along canals and routes there are tree rows and shrub edges formed by Populus x Euroamericana (Euroamerican Poplars), Robinia pseudocacia (Black Locust tree), Morus alba (White Mulberry), residual of the 19th century sericulture, Platanus hybrida (Plane tree), Allanthus altissima (Tree of Heaven), together with autochthonous species like Alnus glutinosa (Black Alder), Quercus robur (English Oak), Salix alba (Common Willow), Ulmus minor (English Elm), Acer campestre (Field Maple).
The following formations have been described:
We just quote some herbaceous species present in the woods of Adda: Orchis militaris (Military Orchid), rare, Leucojum aestivum (Summer Snowflakes), rare almost anywhere, Scilla bifolia (Squill), rare in the Po Plain, Anemone nemorosa (Wood Anemone), Vinca minor (Dwarf Perwinkle), Primula vulgaris (Primerose), Ophris fuciflora (Late Spider Orchid), very rare in the Po Plain, Helleborus niger (Christmas Rose), very rare in plains.
The most interesting faunistic aspects concern above all the avifauna
with the presence of three "garzaie" (places where herons nest) and of
some couples of Marsh Harriers which frequently nest in the Park. Many
other interesting species often come to our area during migrations or
in winter, sometimes in very large groups.
As far as mammals are concerned, the presence of the Polecat in the best-preserved wetlands and of the Dormouse in the largest woods is very interesting.
Particular attention is paid to a small population of Fallow Deer living in the northern woods of the Park.
As far as fish are concerned, we must quote the River Lamprey (Lampetra fluviatilis).
In the Park there are some monasteries which in the Middle Ages worked
as nuclei of monks life and as a support for the neighboring
populations; in addition, there are many farmsteads typical of Lodi -
Crema - Cremona areas.
These very articulated agricultural structures were often provided with oratories, that is small buildings dedicated to prayer; many of these are still present in pretty good conditions.
Moreover, medieval documents, by talking about still existing town centers, quote the Castles which can still be seen in the Park Municipalities.
