The Wetland of Lakes Volvi and Koronia (Lagada)
The lakes of Volvi and Koronia, located east of the city of Thessaloniki, are among the five largest in Greece (Volvi is 2nd and Koronia is 4th). The lakes communicate with each other via two natural water channels, while the lake of Volvi empties in the gulf of Strymonikos via the Rechios river. These two lakes constitute an integrated system, albeit their physiognomy has changed considerably: lake Koronia is shallow, eutrophic and almost deplete of oxygen during the summer; on the other hand, lake Volvi is much deeper, meso-eutrophic with more oxygen during the summer. Around the lakes are situated the following villages: Redina, Mikri & Megali Volvi, Scholari, Nymphopetra, Agios Vasileios and Lagada.
The area boasts of two significant forests: the Redina (flanking the Rechios river) and the Apollonia forest next to the Volvi lake. Three hundred and thirty six (336) species of flora have been recorded in the area, 13 of which are considered rare. Between the lakes stand two age-old plane trees that have been designated natural monuments hosting a multitude of bird nests. The lakes are inhabited by 24 species of fish, 19 species of amphibians and 34 species of mammals. An avifauna inventory produced 200 species of birds. The area is a hot spot for migrating birds, an ideal wintering station and breeding haven for many birds. The Redina straits are the crossing of snake-eagle and golden-eagle.
The area supports mainly agricultural activities and fishery all year round excepting a short period in Spring. The area around lake Volvi is one of the few spots in Greece where the buffalo is raised.
The lowering of the water level poses a major threat for both lakes. This is mainly due to either protracted droughts or to unauthorized pumping of waters for irrigation.
