Transcript of BIODIVERSITY REPORT The Evros Delta Sgouridis Fotis.
THE EVROS DELTA
• The Delta Area Covers Approximately 188km2
• It is Formed by the Alluvial Deposits of the River and shaped by the Sea
LOUTROS
• During rainy seasons, the seasonal stream Loutros also brings fresh water to the Delta.

DRANA LAKEDRANA LAKE
• Drainage works for agriculture after 1950 until 1970 caused major changes in the Delta.
• The most of Drana lake is now drained!

Ecological Value Of The Wetland
1)Recharges groundwater
2) A giant natural filter
3) Photosynthesis
4) Water for drinking and for irrigation
5) Prevents flooding
6) Affects the local climate
7) Grazing and fishing
8) Salt- mines
9) Variety of plant and animal species
10) Research, Education, Entertainment
FLORA- VEGETATIONFLORA- VEGETATION
• Remnants of a formerly extensive Riparian Forest
• This forest needs special care because such habitats are now rare in Greece.

Tamarisks
• Grow in the border areas between salt and fresh water
• It is a hardy plant which withstands flooding and high salinity

Mammals
• Otter is an aquatic mammal that needs clean fresh water and rich vegetation.
• It is a species characterized as vulnerable!
The Little Suslic (Cittelus cittelus)The Little Suslic (Cittelus cittelus)
• Another vulnerable species!!
Birds- Ornithological significance of the Delta
«The Birds Kingdom»
75% of the total Greek species of birds!
• Habitat for nesting and feeding for many groups of birds (herons, cormorants, gulls, and birds of prey
• Wintering area for a large number of waders from northern, central and eastern Europe
• Resting area for large numbers of migratory birds during their migration to and from Middle East and Africa
Mediterranean Gulls (Larus melanocephalus)
• Probably their large colony does not exist any more, due to human interventions in Drana lagoon!
The Mute Swan (Cygnus olor)
• At least 145 different species of birds spent their winter at the Delta
Migratory Birds
• The Dalmatian Pelican (Pelecanus crispus) is a protected species
• The Dalmatian Pelican (Pelecanus crispus) is a protected species
The Flamingo (Phoenicopterus ruber)
• The flamingos have become almost full time residents since 1983
• The flamingos have become almost full time residents since 1983
The Slender- billed Curlew (Numenius tenuirostris)
• Its total population consists of 1000 individuals in the whole world
• The Evros Delta is the most important biotope for that bird’s migration stations
Human Activities- Livestock
• Today the Delta is seriously overgrazed!
• The controlled grazing could help the better managament of the ecosystem and the balance of the biotope
Human Activities- Hunting
• Over exploitation of the stocks of waterfowl, by overshooting, will only destroy the resources completely
Legal- Status
The Evros Delta is included in the following conventions
1) Ramsar Convention
2) Barcelona Convention
3) Bern Convention
4) E.U. Directive 79/409 and Ministerial Decision (3110/3/5/1980)
5) NATURA 2000 (E.U. Directive 92/43)
«The Evros should be allowed to compose and paint the landscape as Nature intended.Let’s not eliminate these lively colors from
its pallet… Let’s protect its beauty!»
