Evrotas River Delta: Natura 2000 habitat mapping
|Area of Lake Vivari, Evrotas Delta, Southern Peloponnese (Photo: D. Koutsogiannopoulos).|
Avrotas is located in the river delta plain, the southernmost river valley in continental Europe and a Natura 2000 site.
Our goal is to monitor and map the housing types based on needs and implementation of housing policies in the country, so it was an interesting learning experience. I also work with fish tracking.
I find the whole concept of habitat types, plant-sociological components, very interesting. It's a tough subject if you're not used to dealing with it - like a pro. So most people don't follow. Of course, any classification will wake you up: you will try to see different shades, different patterns.
We looked at 11 types of housing; I put my "rush ideas" for open storage.
Some key takeaways...
State of the wetlands: Basically, more than 70% of the wetlands in the delta are dry. Due to the high level of water pollution from agriculture, the remains remain very varied. The most beautiful wetlands in the area are the "Clear Lotic Waters" of Evrotas and Vasilopotamos and the vast water fields of the Asteri swamps that reach into Lake Vivari . Usually the area is full of citrus groves, so it could be anywhere in Florida (if you can hide the Peloponnese mountains).
The most interesting habitats in this Natura 2000 site are poorly defined. Aquatic Habitats - Spring habitats are very attractive here, but they are mostly still in an improved (channel) condition. The dunes are beautiful, but behind them the beach is still thin. Near Rawa Asteri, the dry sandy grassland stretches far from the inland beach and is attractive. There are no salt marshes.
A mugil cephalus and other mugilids ( Chelon sp.) were found 7.3 km offshore at the Natura site.
b. Mugilids (including pairs of Gambusia) have been found in the Asterii swamps.
c. Gambusia is particularly abundant in the Rawa Asteri Channel (near the village of Asteri) and Vivari Lake (with mugilids in the lake).
From the lower Avrotus bridge we watched the big sea bass in the water full of Spartan minnow cockroaches. Using binoculars makes it easier to see and taste fish. The water is clear and is very suitable for fish watching.
birds and other wild animals;
We didn't keep any birds but the bird life was disappointing. As expected, few species breed in areas with abundant water and varied topography (often agricultural landscapes). When oranges and olives bloom, maybe not 20 years ago. I feel that a very important unique habitat is being lost and citrus groves are having a tremendous impact on the bird community.
Important breeding species are: blackcap (Evrotus in riparian forests etc.), little bittern (Vivari alang-along), various other waterfowl (Canaiola). There are usually very few large birds. Bee-eaters maintain small colonies. There are few birds of prey (only kestrels and buzzards).
Walking about 3 km from the beach (Alam beach is 13 km long) we only found one sea turtle. We found two dead loggerhead turtles. We found a very small dead turtle which we thought might be a green turtle.
We've seen beach martens around the big city a few times.
Frogs, turtles, etc. can be seen in many areas. A snake can be seen near Vivary; A glass lizard was found dead on the road. Common herbs include the beautiful green Balkan liquorice.

I would like to thank professional naturalist and fellow hiker Dimitris Koutsozianopoulos for all your on-site help and of course for sharing his great photos with me (some of which are posted here). Also the Oasis Hotel in Scala for hosting us so well.
