Parco Regionale dei Colli Euganei

San Daniele is a LIFE Natura site, belonging to the "Natural eutrophic lakes with Magnopotamion or Hydrocharition-type vegetation" habitat type; it owes its name to a nearby hill and is a typical example of highly valuable wetland. It is situated in an area, also known as Lago Verde di Torreglia (Torreglia Green Lake), which is partly used for recreational fishing, and consists of some man-made ponds which used to be part of a system of basins, where clay was once dug for brick production. The ponds have different depths and some of them are flooded throughout the year, whereas others partially dry out in the summer. They belong to a system to collect water, connected with two canals: Rio Calcina and Scolo Rialto.
