Descripción del sitio
| Buda Sas-mountain Nature Conservation Area Territory of the protected area: 30 hectares. Location: The entrance of the protected area is in Tájék St. XI-th district, in the centre of Budapest. Visitors: Visiting is subject to permit, only guided tours are available between 15th March and 15th June at weekends. Management: Directorate of the Duna–Ipoly National Park The white rocks of the Sas mountain is unique not only because of the sight of them. The protected area in the centre of a swarming and polluted a city provides habitat for many indigenous species of flora and fauna. The dolomite of the mountain, formed in the Triassic, rose in the Pleistocene and in the course of that it broke into pieces. The series of folded and eroded white blocks makes up the characteristic mountains of the Buda mountains (Gellért-mountain Törökugrató etc.). In the area of the Sas-mountain – valuable in terms of geology – visitors can see eras of geology from the Triassic white dolomite layers rich in fossils, through flint dolomite containing calcified frames of animals with siliceous test, to the youngest yellowish dolomite-marlite areas. The characteristic details can be studied by the aid of expert guides and well maintained educational paths. The especially rich flora and fauna is characteristic of dolomite areas, as the easily crumbling stone with extremely rich formations result variegated habitats. (The prettiest parts of the Sas-mountain are the cliffs of characteristic shape – e.g. Bear-cliff, or the Beethoven-cliff – the easily crumbling dolomite and later, parts cemented again by the silicic acid of the spouting thermal waters.) The most valuable part of the area are the steep rocky slopes of the upper parts, where valuable open dolomite rock-lawns developed on the thin soil of inferior quality. The majority of areas of the south, southeastern exposure are of sub-Mediterranean character, but some of the northern parts and lower lying areas preserve the cool microclimate. The valuable flora is characterized by such precious rare endemic plants and rare relicts from the Ice Age as the seseli (Seseli leucospermum), heath-rose, a local species of pink (Dianthus plumarius subsp. regis-stephani), or the gymnospermous sea grape (Ephedra distachya), the 'sadler imola' (Centaurea sadleriana), the 'early' thyme and the pasque flower. The valuable and special plant of the stand of the lawns of the area is the rare moor-grass (Sesleria sadleriana), the shoots of which has small bluish green flowers, is a relict from the Ice Age. The areas at the foot of the Sas-mountain are less valuable. The areas contiguous with the rocky areas were originally covered with calciphilous karst scrubforest blended with mahaleb cherries and smoke trees. The loess areas were covered with Tatarian maple-oaks. Unfortunately the great majority of the original associations were cleared in the distant past, very pretty but aggressive lilac shrubs - escaped from nurseries – characterize the area instead.  Bear rock The also valuable fauna is less spectacular, as the majority of the rare and protected fauna consists of insects (beetles, spiders, butterflies). The rare and rarely visible species of the reptile fauna of the Sas-mountain is the precious small-size species also described by Kitaibel Pál called snake-eyed skink (Ablepharus Kitaibelli). http://www.foek.hu/zsibongo/termve/tt/angtt/sashegy.htm |
