Eastern Anatolia and its environs are included in the Irano-Turanian phytogeographical region of Turkiye. The region abounds in highest mountain ranges (average 1900 m) of the country some of which are of quarternary age and volcanic character. Many rivers of historical and international importance like Euphrates, Dicle, Murat, Karasu and Aras. Tigris, Aras and Coruh flow through the region. It experiencens a typical continental climate. Soils are generally of alluvial, colluvial, chestnut-brown, regosal and basaltic types. The area embodies over 8 million ha of meadows and grasslands which is 41% of Turkiye’s total pasturelands as such cattle raising is very high in this area. Forest vegetation is represented mainly by Pinus sylvestris, Quercus libani, Q. longipes, Q. brantii, Q. macranthera, Juniperus excelsa and Betula pendula. Most of these are highly degraded. Plant cover is rich in Irano - Turanian elements but we find Mediterranean and Euro-Siberian elements too to some exten...
This research was carried out in 2006 and 2007 in order to determine the flora of Kırmızı Tuzla (Karaçoban/Erzurum) and Bahçe Tuzlası (Malazgirt/Muş) and their environs. In the area, 1056 taxa belonging to 75 families, and 374 genera were determined. Of all the collected specimens, 70 taxa are new records for B9 square; four taxa belong to Cryptogamae and 1052 taxa belong to Phanerogamae. A total of 101 (% 9.56) endemic species were collected from the area. The distributions of the endemic and rare taxa according to the red data is a follows: 2 taxa in critically " CR " , 8 taxa in endangered " EN " , 30 taxa in vulnerable " VU " , 16 taxa in near threatened " NT " , 63 taxa in least concern " LC " and 2 taxa (Inula discoidea Boiss. and Cicuta virosa L.) in data deficient " DD ". It has been categorised Inula discoidea Boiss. as VU instead of DD. The largest families are Asteraceae (170), Brassicaceae (97), Fabaceae (84). T...
Subalpine vegetation in Giresun Mountains (Turkey)
Acta Botanica Croatica, 2018
In this study, the subalpine vegetation in the Giresun Mountains of northern Turkey was investigated. The study area included north- and south-facing slopes at altitudes ranging between c. 2000 and 2500 meters. For vegetation classification and for describing the relationships between vegetation and environment, traditional Braun-Blanquet methods and multivariate analysis techniques were used. The vegetation mainly consisted of subalpine grasslands and coniferous cushion scrubs. Caricetea curvulae and Astragalo microcephali-Brometea tomentelli were found to be dominant syntaxa in the vegetation of the study area. Land topography, soil physical and chemical factors and species richness have important impacts on the development of subalpine vegetation according to the results of multivariate analysis. Three associations and two subassociations were newly determined and classified. Hemicryptophytes, chamaephytes and geophytes participated in the floristic composition of these syntaxa. ...

A total of 819 species of the vascular plants belonging to 84 families and 370 genera were recorded in the Tahtalı Mountains (provinces Adana and Kayseri), Turkey. Now, Kavşak and Köprü dams are being built in this area. The phytogeographic elements were represented in the study as follows; Mediterranean 178 (21.7%), Irano-Turanian 128 (15.6%), and Euro-Siberian 46 (5.6%). The phytogeographic region of taxa 467 (57.0%) was unknown or multiregional. The number of endemic species was 152 (18.5%). The spectrum of the basic life forms were as follows; Hemicryptophytes 40.2%, Therophytes 25.1%, Chamaephytes 13.3%, Phanerophytes 10.5%, Geophytes 9.3%, Hydrophytes 1.0%, and vascular parasites 0.6%. According to the IUCN Red List Categories, 157 threatened plant species were found in the study area.
Pilot Study for an Assessment of Vegetation Structure for Steppe Rangelands of Central Anatolia
2008
In the last 50 years, rangelands in the Central Anatolian Region of Turkey have been converted to cropping lands, which has negatively accelerated vegetation change, resulting in overgrazing and poor condition and productivity. In these steppe rangelands, to develop a rational basis for making restoration and management decisions, the vegetation structure must be well understood. Thus, the objectives of this study were to: (1) define vegetation patterns through assessing spatial distribution of the plant species and groups, (2) evaluate the relationships between vegetation and environmental aspects and range condition, and (3) outline possible restoration implementations. Therefore, a study was carried out in Paşalı village rangelands of Nevşehir province in 2004. Thirty-seven sites in 733 ha range area were surveyed, and 78 plant species were identified. Most of the identified species were forbs (60), followed by grasses (11) and shrubs (7). The major range species were Thymus sipyleus (7.2%), Festuca valesiaca (6.9%), and Bromus tomentellus (6.4%). Range condition scores fell between 1.20 to 3.40, representing very poor to poor condition. The positive relation of Bromus tomentellus cover, as an enviable perennial grass, with the range condition score (P < 0.001) can pave the way for the condition improvement. Our classification result displayed several groups of species, although there were not many environmental differences, indicating that the groupings are most likely to have occurred due to the spatially-varying grazing intensity. In order to increase the proportion of desirable species in this overgrazed rangeland, the implementation of deferment grazing especially until after seed setting should be essential.
Diversity and gradients of vegetation of Sivrihisar Mountains (Eskişehir-Turkey)
Acta Botanica Croatica
This study was carried out to determine the plant communities and understand the main topographical driving factors of floristic differentiation in the Sivrihisar Mountains (Eskişehir Province). Vegetation samplings were carried out according to the Braun-Blanquet approach. The relevés were stored in the TURBOVEG database management program. Hierarchical classification was carried out in PC-ORD program with Ward’s method and Euclidean distance as a resemblance measure. The diagnostic species were identified by a fidelity measure in the JUICE program. The results of the classification were visualized by ordination techniques in the CANOCO package by using principal component analysis. In conclusion, except for the degraded forest community, all the 7 steppe and 1 scrub plant communities studied were identified and described as new associations. Also, a syntaxonomical scheme for the vegetation of Sivrihisar Mountains was suggested.
