wetlands of Kolkheti Lowland


  • Central Kolkheti wetlands
  • North Kolkheti wetlands
  • South Kolkheti wetlands
  • Vazisubani wetlands
  • Narionali wetlands
  • Kolkheti high-humid region is located in the Western part of Kolkheti lowland and is bordered by the Black Sea from Kobuleti to Ochamchire . In the East the cone shaped part of plane reaches Samtredia.

    The sea level of the sight fluctuates in the limit of 0-22 meters. The region is an ideal flat and is faintly inclined to the sea and is characterised by slight dismembered surface.

    From the geological point of view the region is young. Its formation started in the middle of Holocene during last 5-6 thousand years. Geomorphologically it is an accumulating plane with high hydrographical net. The big rivers ( Rioni, Tskenistskhali, Abasha, Tekhuri, Khobi, Natanebi, Supsa) are transit rivers supplied by: snow, rain, ground and glacial waters. The small rivers are marsh type. There are several lakes in the region . The significant one is Paliastami with the water table of 18,2 sq. km., 3,2 meters depth. The lakes are located in the coastal part and are of lagoon origin. In the central part of the plane there are river origin lakes , which are the subjects of a significant anthropogenic impact.

    The most important parts of the region are wetlands, those are divided in three parts: South, North and Central wetlands in Kolkheti include types commonly referred to bogs, marshes, swamps and salt marshes. The major part of the wetlands are located in the central part and is composed by: Anaklia-Churia, Chaladidi (Nabada) and Pichora- Paliastomi. The majority of scientists suppose the territory as a single whole sight , because of common geological , geomorphological, soil, flora and fauna characteristics.

    The botany of the sight is diverse with and composed by the complex of endemic and relict species phytocenose. The major part of the region is assimilated . The anthropogenic impact on wetlands: their draining and industrial peat mining caused the reduction of phytocenose . In spite of that there are still existing several original natural plant communities.

    There are coastal peat bogs between the mouths of the Supsa, Rioni, Khobi and Enguri rivers, just behind the relict coastal bank (Grigoleti, Imnati, Nabada, Churia etc.). The surface of the peat bogs is almost at the sea level, and the peat reaches to the depth of 5-12m (i.e. most is immersed below sea level). The age of the deepest formations is estimated to be 6200-5800 years (radiocarbon method).

    The region and its coastal part is an important range for 21 species of migratory birds, their recreation and wintery.

    Central Kolkheti wetlands (Churia, Nabada, Pichora) and Ispani II have been designated as a Georgian RAMSAR site and the relevant act is now at the final stage of parliamentary approval.

    The Management Guidelines for the establishment of Kolkheti National Park has been prepared with methodological assistance of WWF in co-operation with the World Bank /GEF and within the frameworks of the Protected Are as a System of Georgia. It was preceded with the Decree #11 of the Government of Georgia "On establishment of national parks on the territory of Georgia"-dated May 12,1992 ; Order # 562

    The establishment of Kolkheti National Park and Kobuleti Nature Reserve, on the other side is rendering the status of the wetlands of International Importance to them. As a result of the next planning stage: elaboration and implementation of a full value management plan will create favourable conditions for nature protection and social -economic development of the region.

    The Brochure "Bell of Alarm on Kolkhety wetlands" is published as a part of the project of Georgia Youth EcoMovement (SAEM). "The Establishment of the Black Sea Youth EcoAcademy", that was implemented in the framework of the Integrated Coastal Zone Management (ICZM) Programme.
