The small Oasis, once managed by the WWF section of Bologna, preserves a stretch of hydrophilous woodland along the left bank of the river Idice, near the ruins of an old mill. A monumental oak, willows, poplars, alders, and narrow-leafed ashes, as well as the very widespread black locust tree and several shrubs are an example fo the vegetation also growing along the other local watercourses. A series of labels highlights the main botanical species.
