Özet
Meralar gerçekte hayvanlar içi n yem kaynakları olarak bilinirler. Ayn ı zamand a meralar, s u kaynağ ı , zengi n flora ve fauna olma özelliği ve dinlenme alanı gibi çok yönlü kullanımlar için potansiyel kaynaklara sahipti r. Meralar uzun süreli optimum fayda sağlamak için dikkatli kullanılmalı ve muhafaza edilmelidirler. Bu alanlar hala kötü yönetim nedeniyle bozulmakta ve bu bozulma süreci devam etmektedi r. Mevcut mera durumu iyi yönetim uygulamalarıyla tersine çevrilebili r. Bu sebeple Sivas ili meralarında 2008, 2009 ve 2010 yıllarında arazi çalışmaları yürütülmüştü r. Vejetasyon etüt çalışmaları lup ile modifiye edilmiş tekerlek nokta yöntemi il e Sivas meraların ı temsi l eden 103 durakta yapılmıştı r. Bu çalışmanı n sonucund a bitkiyl e kapl ı alan % 60,68 olarak bulunmuştu r. Azalıc ı v e çoğalıc ı bitki türlerini n kaplam a oranları sırayl a % 15,53 v e % 22,23 tü r. İncelenen mera duraklarında iyi, orta ve zayıf durumda olan duraklar sırayla 6, 62 ve 35 olarak bulunmuştu r. Toplam durakların 97 adeti mera durumu orta ve zayıf sınıflamada yer almıştı r. Diğer taraftan, mera sağlığı açısından yapılan sınıflamada 26 durak sağlıklı, 35 durak riskli, 42 durak sorunlu olarak bulunmuştu r. Toplam 77 adet durak mera sağlığ ı açısından riskl i v e sorunludu r. Çalışm a sonuçları , meraları n yavaş olarak bozulm a eğiliminde olduğunu ve bu alanların uygun ıslah ve yönetim uygulamaları ile başarılı olarak orijinal hallerine dönme potansiyeli taşıdığını, göstermişti r.
Rangeland s are actuall y known as feed resources for animals . t th e sam e tim e they hav e potentia resources for multiple-uses such as water source, rich of flora and fauna, and recreation areas. They should be carefull y used an d conserved for thei r optimu m benefits of lon g term . Deterioration an d degradation process have still continued due to mismanagement of rangelands. Present range status should be reversed with good management practices. For this reason, field works were conducted on the rangelands of Sivas Province in years of 2008, 2009 and 2010. A modified wheel point method with loop was used for vegetation survey i n th e 103 representativ e stud y sites of rangeland s i n Sivas province. Th e results of thi s stud y indicated that vegetation cover was quantified as 60.68%. The cover rates of decreasers and increasers were 15.53% and 22.23%, respectivel y. The studied sites numbers were 6, 62, and 35 for good, fai r, and poor conditions, respectivel y. The 97 sites of total sites were identified as fair and poor in condition based on the rangeland condition classes . O n th e other hand , 26 sites were foun d at health y, 35 sites at risky an d 42 sites at unhealth y in rangeland health categories. Total site number of the last two classes was 77. Study results indicate that rangelands are also in slow degradation trend and high potential for having been successively reversed to the climax situation with proper restoration and management practices for rangelands.
