Working with Nature in the Port of Seville (VIDEO)

The Port of Seville improves navigation, and at the same time promotes biodiversity in the Guadalquivir estuary.

Each year, part of the sand extracted from the maintenance dredging of the canal is reused for the creation and conservation of wetlands for aquatic birds.

These habitats, designed together with the Spanish National Research Council, are safe environments rich in nutrients. These ecosystems are very beneficial for the rest, reproduction and breeding of the bird species in the Doñana area.

There is a high level of biodiversity and variety in the wetlands, with over 70 species of birds recorded. Some are endangered, such as the ferruginous pochard, the marbled duck, the squacco heron and the red-knobbed coot; and others are vulnerable, such as the osprey.
