Wetlands of San Fernando, Cádiz



A giant’s scribbles, a plasticine labyrinth, water serpents, a
puzzle of hope… Stories are real.

Wetlands of San Fernando, Cádiz
36º 30’ 08.67’’ N 6º 11’ 07.64’’ W / January 23, 2006
Wetlands of tidal influence formed by deposits of mud and dirt
from the Guadalete River. The photograph shows the meandering
design of the wetland’s hydrological network. The dark colors are
produced by the activity of sulfurous bacteria that make use of
the absence of oxygen caused by the compaction of these
sediments. The intense greens are due to the enteromorpha
algae that cover the inter-tidal zones.
Protection status: Bay of Cádiz Nature Park.
