Its geological origin dates back thousands of years ago to a shoreline gulf that was separated from the Mediterranean sea through the sedimentation brought down by the Túria and Xùquer rivers. At the present time the Albufera Nature Reserve has a large number protected habitats included in the Habitats Directive. This great variety of mor- phological aspects can be defined in three overall environments: · The coastal sandbar. This is the sediment that separated the whole system from the sea. Here one can still find a well-conserved dune line, in which there is a good sample of the vegetation proper to Mediterranean Máquia and malladas, small areas of brackish waters, lying between the dunes and the “Devesa” forest system. · The rice fields, forming the environment with the greatest surface area, (14000 hectares), as this cov- ers two thirds of the total surface area of the nature reserve. Originally, when it was closed off, the sur- face occupied by seawater gradually turned into a large marsh of brackish waters to end up forming, from the 15th century onwards with rice-growing, one of Spain’s main rice-production areas. Criss- crossed by a large network of irrigation ditches and channels, its cycles of flooding and waterlogging make it one of the main feeding areas for the rich Albufera birdlife. There are small springs which are locally known as ullals scattered mainly over the western sector. · The Albufera lake is a coastal system with a sur- face area of 3000 hectares of shallow waters, with around 300 hectares of banks and islets on which dense swampland vegetation grows. It is important through its significance in regulating the water flow in the rice fields, as well as through its ecological and landscape value. Spectacular sunset over the Albufera lake.

Vegetation Most of the reserve’s surface area is taken up by rice crops and by the lake or lagoon itself, which means that the autochthonous vegetation is limited on one hand to the channels, the “ullal” springs, areas bordering the paddy-fields and on the other side the sandy coastal strip, particularly the Devesa and line of dunes. On the sandy beaches of the Nature Reserve, as well as on the immediate dunes, there is a set of plants adapting to the harsh conditions of these environ- ments, where wind and high salinity are prevalent. Here one can find the borró grass, as well as the sealily and sea bindweed, amongst others. On the stabilised sandy area behind the dune zone there are patches of plurispecific bushland, amongst which the presence of lentisk and Italian buckthorn stand out. The vegetation of the inter-dune salt marshes has settled in soils that are particularly enriched with salts and regularly waterlogged. The dominant botanical species are the saltworts, which form a sub-environment of great importance due to their scanty presence in the Valencian Community. In the areas where there is freshwater and less brackish substrates, one can find diverse botanical communities associated with wetlands, formed mainly by submerged and floating swamp plants, of great diversity and special importance. The sub- merged plants or macrophytes have the best popu- lations in the ullal springs and in the channels with best water quality. As for the swamp vegetation of waterlogged zones, the prominent species are giant reeds, reed mace, saw-sedges and the Kosteletzkya pentacarpos or “trencadalla”, mainly spread over the islets in the lake.
