EL HONDO NATURE RESERVE, which lies between Elche and Crevillent, was designated an Area of Outstanding Natural Beauty in 1988 and subsequently declared a Nature Reserve by the Regional Government, the Generalitat Valenciana, in 1994. Appearing in the lists of the RAMSAR, it is classified as a ZEPA (Protected Area for Birds) due to the importance and abundance of its bird life. There are 172 species, of which about 50 nest here. Among them are the marbled teal, one of Europe’s most threatened birds and the white-headed duck, also at risk of extinction, as well as herons, several types of wading duck and flamingos. Also found living in this water environment are eels, grey mullets, carp and the common tooth carp, a small fish endemic in the Spanish Mediterranean.
