The Association Stipeto-Convolvuletum Compacti ASS. Nova in Kosovo
Serpentine vegetation of Kosovo represents a diversity which has not been sufficiently explored, yet. Kosovo's serpentine is spread in different parts of Kosovo at the altitudes of 400-2100 m. Large complexes with serpentine are found in the north of Kosovo, but the southern part of Kosovo is also rich in serpentine rocks and in endemic species.
Using the principles and methods of the Zürich-Montpellier School we have explored the serpentine flora and vegetation of Gurana, an area in the south-east of Kosovo near the border with the Republic of Macedonia. This area has not been sufficiently researched because of the militarized border areas. During the research of these fields, we found species that were not present on the other serpentines of Kosovo.
The species Convolvulus compactus Boiss. (syn. Convolvulus cochlearis) and Stipa mayeri dominate this terrain and create stands that we have classified as the association Stipeto-Convolvuletum compacti ass. nova. This association was researched during 2007-2010. Based on the results obtained and comparing them with the results of other authors, we have arrived at the conclusion that we are dealing with a new association which we called Stipeto-Convolvuletum compacti ass. nova.
Sixteen endemic plant taxa were selected from Kosovo, according to the IUCN standards and for each taxon the risk assessment and threat category has been assigned. The taxa were compared with their previous status from fifteen years ago. From sixteen plant taxa, which were included in this work, four are Balkan endemics, whereas, eight of them are local endemics and four of the taxa are stenoendemics. Six of the taxa are grown exclusively on serpentine soils, five of them on limestone substrate, four of them in carbonate substrate, yet only one in silicate substrate. The work has been done based on the standard working methodologies of the IUCN (Guidelines for Using the IUCN Red List Categories and Criteria – Version 8.1). The most threatened plant taxa is Solenanthus krasniqii – which after its observance has only 20 mature individuals. As a result of the wild collection of the medicinal and aromatic plants, from the local population, Sideritis scardica is about to be completely go extinct. The aim of this study was to assess the state of endemics in the threats possessed to them during the previous times, present and predicting the trends for the upcoming years.
