Lake
Mikri Prespa is a Ramsar site (8,000 ha), Special Protection Area
and Specially Protected Mediterranean Area. Both lakes form a
National Park (19,470 ha).
It
is about two lakes of a mountain drain basin that are split by
a narrow land strip and are surrounded by mountains. Greece
is sharing Lake Mikri Prespa with Albania and Lake Megali Prespa
with Albania and F.Y.R.O.M. Lake Mikri Prespa has several extended
shallow zones with reedbeds and aquatic vegetation, wet meadows,
pastures and agricultural land. The main human activities are
agriculture, fishery and hunting. In 1985 the Greek Government
launched a development pilot program that was financed by the
European Union and was aimed to develop agriculture, aquaculture
and to extend the road network. The result was a serious ecological
damage that was caused by the cutting of the remaining riverine
forest, the clearing with dredging machines of the canals that
were rich in aquatic vegetation and the creation of a fish pond
in a vital feeding site for herons. This fishpond was never put
into service.
It
is the only place in Europe (except for the Danube Delta and the
former U.S.S.R.) that both White Pelicans Pelecanus onocrotalus
and Dalmatian Pelicans Pelecanus crispus breed. In 1984 their
populations were, respectively, 116 and 165 pairs and these numbers
are rather stable for the last 10 years. The
numbers of herons (Ardeidae) were fluctuating (some species showed
a decline) and include the Little Bittern Ixobrychus minutus (50
pairs), the Squacco Heron Ardeola ralloides (50-100 pairs), the
Little Egret Egretta garzetta (fewer than 100 pairs), the Great
White Egret Egretta alba (fewer than 10 pairs) and the Purple
Heron Ardea purpurea (3 pairs). Glossy Ibis Plegadis falcinellus
does not breed any more.
Other
breeding species are the Cormorant Phalacrocorax carbo sinensis
(600 pairs), the Pygmy Cormorant Phalacrocorax pygmeus (100-150
pairs), the Spoonbill Platalea leucorodia (2 pairs, at former
times the maximum number was 200 pairs), the Grey Goose Anser
anser (maximum 170 pairs, the main breeding site in Greece), the
Ferruginous Duck Aythya nyroca (10 pairs), the Goosander Mergus
merganser and the Red-breasted Merganser Mergus serrator (small
population, the southernmost area in Europe and the only one in
Greece), the Egyptian Vulture Neophron percnopterus, the Short-toed
Eagle Circaetus gallicus (2 pairs), the Marsh Harrier Circus aeruginosus,
the Golden Eagle Aquila chrysaetos (2 pairs), the Hazel Grouse
Bonasa bonasia (one of the few areas in Greece), the Rock Partridge
Alectoris graeca, the Whiskered Tern Chlidonias hybridus, the
Kingfisher Alcedo atthis, the Medium Spotted Woodpecker Dendrocopos
medius, and the Lesser Grey Shrike Lanius minor. At winter, thousands
of ducks are recorded, despite the freezing of the lakes.
