Özet
Bu çalışmada, Çankırıda yapılan 41 adet mera vejetasyon etüdüne dayalı olarak il meralarının floristik özellikleri incelenmiştir. Vejetasyon etüdü tekerlek-nokta yöntemiyle yapılmıştır. Çalışma sonucunda 46 familya ve 187 cins içinde 327 adet tür tespit edilmiştir. Bu türlerin 38 tanesi buğdaygil, 56 tanesi baklagil, 47 tanesi papatyagil ve 141 tanesi de diğer familyalara aittir. Bitkiyle kaplı alan içerisinde buğdaygil, baklagil ve diğer familyaya ait türler sırayla %36.3, %12.8 ve %50.9 oranlarında bulunmaktadırlar. Yine meralarda en sık rastlanan familyalar sırasıyla Poaceae (3880), Lamiaceae (1676), Fabaceae (1367) ve Asteraceae (802)dir. En yüksek örtüşe sahip 20 türün 10u Poaceae, 1i Fabaceae ve 9u diğer familyalardandır. Meralardaki örnekleme başına ortalama tür sayısı 31.4 (standart sapma8)tür. Meralarda en çok rastlanan cinsler Astragalus (19), Trifolium (7), Centaurea (7), Alyssum (7), Trigonella (5), Ranunculus (5) ve Medicago (5)dur. Çankırı ilinin zengin flora yapısı mera alanlarının ıslahında kullanılabilecek yem bitkilerini içeren önemli bir bitki gen kaynağı olarak belirlenmiştir. Anahtar Kelimeler: Çankırı, mera, flora
In this study, floristic features of çankırı rangelands were observed on the basis of 41 vegetation surveys in the rangelands of çankırı province. Vegetation surveys were performed with wheel-point method. As a result of this study, identification of the specimens revealed that the presence of 327 taxa belonging to 187 genera of 46 families. In covered area by vegetation, ratio of grass species was 36.3%, ratio of legume species was 12.8% and ratio of species belonging to other families were 50.9%, respectively. One of the most common families in pastures was Poaceae (3880 times), Lamiaceae (1676 times), Fabaceae (1367 times) and Asteraceae (802 times) families. The 10, 1 and 9 species of the 20 species having the highest covering area were Poaceae, Fabaceae, and other families, respectively. The average number of species in pastures was 31.4 (standart deviation 8). The most common genera in pastures were Astragalus (19), Trifolium (7), Centaurea (7), Alyssum (7), Trigonella (5), Ranunculus (5) and Medicago (5). Rich flora structures were detected in rangelands of çankırı province and forage crops existed as plant genetic resources for rangelands rehabilitation.
