Solar salt works are unique constructed ecosystems
Solar salt works are integrated constructed coastal ecosystems with a unique architecture. They consist of a system of shallow ponds connected mainly in series through which seawater flows, evaporates by the power of sun and wind, and deposits sodium chloride in crystallising ponds.
The exploitation of sea salt contributes to the development of biodiversity with fauna and flora specific to wetlands. The spatial organisation of the ponds and their different depths and salinity levels favour the development of a variety of micro-environments and microorganisms (algae, bacteria, molluscs, worms etc) which are attractive to a wide range of bird and fish species. This kind of habitats for communities of salt-tolerant vegetation and aquatic invertebrates are rarely found in other types of environments.
