Descripción del sitio
| Adony Nature Conservation Area Territory of the protected area: 1 hectare. Location: The protected area is situated to the southwest of Adony along the road to Perkáta. Visitors: Visiting of the fenced area is subject to permit and only guided tours are available. Management: Directorate of the Duna–Ipoly National Park According to the latest views of nature conservation it is not possible to save a species by protecting its single representatives – let it be a species of either flora or fauna. Long term effective protection can be attained if a larger part of the habitat of a given species can be placed under protection – even considering migration routes or areas for expansion. Still quite often, there are cases when just a few square meter habitat of – usually an especially endangered – species has to be protected by fencing or/and by a guard so as to provide a last chance for survival of a little population. That is the situation in the case of the milkvetch (Astragalus dasyanthus), too. The highly protected milkvetch is a Pannon species and the centre of its range is the Carpathian Basin and it stretches to the northern border of the Balkan in the south and to the Ukrainian sanded steppes in the east, but it is not present to the west or north of Hungary – on top of it all, it has already become extinct in Bulgaria and to the south in areas of Croatia and Serbia. Originally the milkvetch was a member of a dry sanded steppe association of plains and hill countries and it hardly tolerates disturbances, therefore by breaking up meadows and sloping steppes it became even more endangered than its relative, the stemless milkvetch (Astragalus exscapus). That is why some of its habitats are highly protected – just like the one hectare chalky loess-sanded ground beside Adony, where it is trying to survive in a little area.  To reduce transpiration the whole plant is covered with fluffy hair, which makes the plant look silver green from the distance. It produces yellow papilionaceous flowers from May. If picked or dug out, the milkvetch dies in a short time – it is not worth trying doing that – which also renders the saving of it difficult. Visitors can see the plants with a characteristic colour, shape and prominent flower from the border of the fenced area, too – without further reducing its chances for survival by stamping on them. Being in Adony it is worth seeing the system of fish-ponds in Lívia a few kilometers from the village, the valuable fauna of which is charcterized by such rare species as the black-necked grebe, the gray leg goose, the squacco heron, the spoonbill or the bluethroat, the Savi's warbler and the yellow wagtail. The green sandpiper and the osprey are not rare sights either during migration. http://www.foek.hu/zsibongo/termve/tt/angtt/adonyi.htm |
