The middle course of the Piave river, north of the town of Treviso, including the surrounding wooded hills (Colli Maser). Dominant riparian habitats are wet grasslands and woodlands (Alnus, Salix, Populus), alluvial flats of gravel, sand and mud, and also steppic areas.
There is an important flyway of migrating raptors along Colli Maser, mainly Pernis apivorus (3,000-5,000 per season). Breeding species of global conservation concern that do not meet IBA criteria: Crex crex (6 pairs). A small heronry is present.
Pressure/threats to key biodiversity
The most important threat is the excavation of new gravel-pits. The area is a proposed Regional Park.
