Salt works, fishing and shell-fishing in the estuary, openrange livestock-raising, forest harvesting (pine kernels,firewood, honey). Integrated management in the surroundingsof a potentially highly contaminating industrialchemical plant.
Tidal marshes scattered with islands bordered by many streams, beaches and dune systems. The erosion and sedimentation processes taking place give rise to rapid morphological changes.
The Mediterranean climate is softened by the influence of the ocean with a mean annual rainfall a little above 500 mm. The wetland vegetation is dominated by halophile species (adapted to the high salt content of the soil).
There are also strips of Italian StonePine and Spanish Juniper. The extraordinary wealth of bird life in the area is to be noted and includes species such as the Grey Heron, the Purple Heron, the Western Marsh Harrier and the Spoonbill (one third of the wholeEuropean nesting population is to be found in the Marismasdel Odiel).
After Doñana, with which for reasons of proximity it maintains a continuous link, Marismas del Odiel is considered to be the second most important wetland area for water fowl in Spain based on the diversity of species recorded.
