The ecological improvement of the Órbigo River is one of the most ambitious projects of the National River Restoration Strategy (ENRR), which involves recovering and improving both the lateral fluvial areas and the dynamics of the river and the longitudinal connectivity of its 108 km in length, from its source in the province of León by confluence of the Luna and Omaña rivers.  to its mouth in the Esla River, in the province of Zamora.

The project involves the intervention through three different phases of action, having concluded the naturalization works of the upper section (Section I), about 23.5 km long, with the elimination of embankments and breakwaters, reforestation of riverbanks and recovery of canals and adjacent river areas, with a high natural capacity to mitigate floods.

Its development included an important process of public participation where the local population was involved, managing conflicts that arose with the inhabitants of the affected riverside towns.
