Bu çalışmada mevcut literatürlerin taranması ve 2 yıllık (2018-2019) arazi çalışmaları sonucunda Siirt il sınırları içerisinde yayılış gösteren bitki taksonları araştırılmıştır. Literatür araştırmalarında Siirt ili sınırları içerisinde 786 taksonun varlığı belirlenmiştir. Arazi çalışmaları sonucunda bu taksonlardan 447 tanesi toplanmış ve kayıt altına alınmıştır. Ayrıca bu çalışma ile Siirt ilinde 89 taksonun yeni yayılışı tespit edilmiştir. Elde edilen sonuçlara göre Siirt il sınırları içerisinde toplam 875 taksonun yayılışı belirlenmiştir ve bu 875 taksondan 71 tanesi (%8.11) endemiktir. Endemik veya endemik olmayıp tehlike altında olduğu değerlendirilen toplam 95 taksonun 6’sı “CR” Kritik; 10’u “EN” Tehlikede; 33’ü “VU” Hassas; 18’si “NT” Tehdide açık, 23’si “LC” Düşük riskli ve 5'i “DD” yetersiz veri kategorilerinde değerlendirilmektedir. Tespit edilen taksonlardan 329’u İran-Turan elementi, 90’ı Akdeniz elementi, 35’i Avrupa-Sibirya elementi, 4’ü Karadeniz elementi iken 417’si ise fitocoğrafik bölgesi bilinmeyen veya çok bölgeli türler kategorisinde yer almaktadır. Çalışma sonucunda en fazla takson içeren ilk beş familya sırasıyla Poaceae (115 takson), Fabaceae (109 takson), Asteraceae (95 takson), Apiaceae (56 takson) ve Lamiaceae (53 takson)’dir.
In this study, the scan of existing literature and the result of 2 years (2018-2019) landwork, plant taxons that spread within the Siirt province borders were investigated. In literary research, there are 786 taxons within Siirt's limits. As a result of the land studies, 447 of these taxons were collected and recorded. In addition, this study has also identified the new spread of 89 taxons in Siirt province. According to the results obtained, the spread of a total of 875 taxons within the Siirt province limits has been determined, and 71 of these 875 taxons (8.11%) are endemic. 6 of the total 95 taxons not endemic or endemic and under danger are "CR" Critical; 10 are "EN" Danger; 33 are "VU" Sensitive; 18 are "NT" Danger Open, 23 are "LC" Low-risk and 5 are "DD" Insufficient data categories. Of the identified taxons, 329 are Iran-Turan elements, 90 are the Mediterranean elements, 35 are the European-Siberian elements, 4 are the Black Sea elements, and 417 are in the category of unknown or multi-regional species. The first five families with the most taxons are Poaceae (115 taxons), Fabaceae (109 taxons), Asteraceae (95 taxons), Apiaceae (56 taxons) and Lamiaceae (53 taxons) respectively.
In this study, the plant taxa that spread within the provincial borders of Siirt were determined by scanning the existing literature and as a results of the 2-year (2018-2019) field study. In the literature review, the existence of 786 taxa within the borders of Siirt province was determined. As a result of the field studies, 447 of these taxa were collected and recorded. In addition, with this study, it was determined that 89 new taxa are distributed in Siirt province. According to the results, it was determined that a total of 875 taxa are distributed within the provincial borders of Siirt and 71 of these 875 taxa are endemic (endemism rate 8.11%). Out of 95 taxa that are not endemic or endemic and are considered endangered are evaluated in categories as follows: 6 taxa "CR" Critical, 10 taxa are "EN" Endangered, 33 taxa are "VU" Vulnerable, 18 taxa are in "NT" Near Threatened, 23 taxa are in "LC" Least Concern, and 5 taxa are in "DD" Data Deficient. Of the detected taxa, 329 are Iran-Turan elements, 90 are Mediterranean elements, 35 are European-Siberian elements, and 4 are Euxine elements while 417 belong to a phytogeographical region or multi-regions. As a result of the study, the first five families with the most taxa are, respectively, Poaceae (115 taxa), Fabaceae (109 taxa), Asteraceae (95 taxa), Apiaceae (56 taxa), and Lamiaceae (53 taxa).
