Site description (2000 baseline):
Site location and context
Lake Velence is the third-largest lake in the country, measuring 10.5 km in length and 3.3 km in breadth, with an average depth of 1-2 m. There are extensive reed-beds with
Phragmites and
Typha, and adjacent wet meadows. Human activities include fishing, angling, sailing, boating and reed-harvesting (`Other' land-use, below).
An important site for breeding herons (Ardeidae) and ducks, and as a roosting site for geese in winter. Breeding species of global conservation concern that do not meet IBA criteria:
Aythya nyroca (4-5 pairs).
Pressure/threats to key biodiversity
Main threats are disturbance to birds, and over-abstraction. Water-levels are artificially maintained in order to protect the ecological integrity of the site, and to prolong opportunities for recreational use. Wildfowl shooting is banned, and a management plan for Fertõ was prepared in 1996. Expansion of the protected area at Dinnyés by 600 ha is underway.
