Unlike the already mentioned Magredi, where water disappears, in the case of resurgences, instead, water resurfaces in “pools” similar to small ponds. This phenomenon is caused by the impermeability of the soil of clay, which makes water slow down and forces it to rise. These pools, then, originate many rills and small brooks which gather together and form the river Noncello, which passes through the municipal district of Cordenons in the South, reaching the district of Pordenone, where it flows into the river Meduna.
The whole territory is a fine habitat for many flora and fauna species.
Besides the natural phenomena, in comparison to the Magredi, in the Risorgive of Vinchiaruzzo there is also a change, first, in the flora and, then, in the fauna.
Most of the area nearby the pools is covered with poplars tree plantations, but with regard to the trees, there are also alders, acacias and medium-tall forest trees. Always nearby the pools, in the brushwood, there are varieties of “herbs” typical of the marshy zones, but the farer you go from them, the more similar the environment becomes to the “evolved Magredo”, that is, rich of large meadows of grasses and fodder plants.

The fauna variety is great, in particular within the birds.
Besides the common blackbirds (turdus merula) and the sparrows (passer domesticus), typical species of this area are the buzzard (buteo buteo) and other Passeriformes such as the nightingale (luscinia megarhynchos).
Among the poplars, then, the typical tapping of the woodpecker, especially the green woodpecker (picus viridis) is not seldom to be heard nor to be seen. Then, hares are remarkably present next to some foxes and other small mammalians. Besides their many differences, Magredi and Risorgive of Venchiaruzzo have many points in common. First of all, because of the drought in the Magredi, the Risorgive are considered like a club by the birds that nest in the former, where they can fly and drink, and then go back home. The symbol of the close relationship between Magredi and Risorgive is also represented by the presence in both areas of the rare Montagu’s harrier (circus pygargus), for which the WWF launched a campaign of national protection because of the reduction of habitat suitable for this bird.
This bird nests at the boarder between the two zones and preys in the Magredi. Nowadays, though, due to projects especially concerning the roads development, the reletionship between these two environments, which are so different but at the same time so interdependent on one another, runs the risk to be broken.
