Po Basin mixed forests
Po Basin mixed forests is a term used to describe an ecoregion and biome composed of trees and other vegetation found in the temperate broadleaf and mixed forests surrounding the Po River in Northern Italy, and its watershed from the Cisalpine, or Italian side, of the Alps.
Description
Terrestrial plants
The Po Basin mixed forests consists of remnants of:
1. Mixed deciduous oak/hornbeam forest -
2. Riparian forest, as well as flood-plain vegetation of the Po Basin -
Aquatic plants
The freshwater ecosystems (zona umida) have a high level of biodiversity.
Threatened (in Italy) plant species include
- Leucojum aestivum
- Halocnemum strobilaceum
- Nymphaea alba
- Bassia hirsuta
- Limonium bellidifolium
- Utricularia australis
- Thelypteris palustris
- Salvinia natans

Fauna
Lesser-disturbed wetlands which are important breeding areas for many bird species are most significant biodiversity of the ecoregion. Examples are Grey Heron, Purple Heron, Great Egret, Little Egret, Squacco Heron, Cattle Egret, Great Bittern, Little Bittern, Pygmy Cormorant and Ferruginous Duck.
Conservation
The region is industrialised and has a long history of human pressure (pollution, shrinkage of wetlands, invasive species, and unsustainable hunting of waterfowl).
