The history of Spilimbergo cannot be separated from the river that borders it: the Tagliamento. Of the original vegetation formations that covered the Spilimbergo area in ancient times, currently, only scant traces remain.

The vast peninsula between the Cosa stream and the Tagliamento river, where human settlements now exist, was still historically covered by a dense plain oak forest that also descended along the rain-alluvial gullies (muculis), which discharge water into the river, connecting to the riverbed flora.

Some weak traces of the original layout, although anthropized, can still be identified in the site called Bosco di Valeriano a few kilometers north of the city, and in some riparian fragments of the Tagliamento south of the Duomo of Spilimbergo. For the rest, the residential settlements have caused the disappearance of the natural forest and, for some years, trivial intensive cultivations are also altering part of the Aga Granda riverbed.
