| Sárvíz valley Landscape Protection Area Territory of the protected area: 3 616 hectares, of which 157 hectares are under increased protection. Location: The seven protected parts are situated between Tác and Sárbogárd along the Sárvíz brook and the Malom (mill) canal. Visitors: The major part of the area is freely accessible for visitors but there are areas that are subject to permit or closed. Management: Directorate of the Danube–Ipoly National Park The valley of the Sárvíz (muddy water), formed in a roughly northwest-southeast fault from the foot of the Bakony to the hills of Szekszárd, sinks towards south. Its catchment area – around Sárvíz brook as its axis – directed and partly directs even today the waters to a huge territory. Until the twentieth century this region was an unbroken wet, marshy land, which was drained as late as the 1920s only with a network of still living canals. The area lying lower than its surroundings operating as a natural water-basin, however, turned into a place with stagnant water abundant in larger and smaller lakes during the time of rainy periods, where no quality cultivation can be pursued except for the higher lying parts. Attempts of rice production were made some time ago and by now it has also become a useful bird protection investment, because the abandoned rice fields became valuable shallow ponds with reed creating a habitat for a large community of littoral birds. In the valley of the Sárvíz former water-levels made it possible to turn smaller lakelets into fishponds, thus in addition to the marshy communities, large open water surfaces were formed, where a great number of common herons and purple herons, little egrets and great white herons, night herons, squacco herons hatch. The still wet area turning into swampy marshes when it rains a lot is divided by patches of grey sallows and willow-ash galleries. Large mixed communities of herons can be found in the often ten meter wide zone of reed surrounding the fish-ponds (for example east of Soponya) while hundreds of black-headed gulls hatch on the island in the lakes raising deafening cacophony.  As in many places in Hungary, after the drying up of the territory secondary salinification took place in parallel with the remaining wet habitats, and saline lawns appeared. The characteristic communities of the territory are similar to those of the sandy steppes between the Danube and the Tisza. These habitats still protect masses of valuable, protected plants. In the valley of the Sárvíz, primarily on its eastern side, several larger or smaller saline lakes can be found with saline or salinificating lawns. The flora and the fauna living here recall the saline areas of the Alföld. In addition to the typical saline plants of the valuable artemisia meadows the crocus sp. (Crocus reticulatus) appears and several species of the iris as well. From among the most valuable birds the avocet, the redshank, the black-tailed godwit and the little ringed plover hatch on the saline (mainly near Sárszentágota, Sárkeresztúr and Fels?szentiván). Among the saline patches of the fields near Sárszentágota and remaining gallery woods milkvetch (Astragalus exapus), and feather grass, as well as several species of wild orchid still can be found. The frequent patches of Camphorosmetum annuae on the meadow of the larger uninterrupted protected area near Sárkeresztúr recall the salines over the Tisza, though the captivatingly beautiful varied landscape patterned with smaller and broader hills anticipates rather the southern parts of the Sárvíz valley. The higher lying sandy parts are often situated within a couple of metres from the world of marsh, in such cases a few steps away from the drought resistant plants of the sandy steppe lawn we can admire the wild orchid of the marshy meadow. Smaller steppe lawn patches recalling the ancient Mez?föld remained in several parts of the area, often with rich and varied flora, since several species of orchid blossom on these small patches, for example near Aba (military orchid, bug-orchid and green-winged orchid). In addition to the more than a hundred species of birds hatching in the Sárvíz valley the white-tailed eagles, black storks frequently come to feed in the area and the fish-ponds see ospreys as well. During migration tens of thousands of bean geese, white-fronted geese, and the various species of ducks occupy the lakes and their vicinity. The larger or smaller patches of wood, poplars, elms, ash-trees, willow groves offer home for harriers, red-footed falcons, kestrels (blood hawks) and long-eared owls and also one of the most beautiful Hungarian birds the roller is quite frequent along the Sárvíz. http://www.foek.hu/zsibongo/termve/tk/angtk/sarviz.htm |
