Orta Anadolu Bölgesine Ait İki Merada Mera Durumu, Sağlığı ve Biyoçeşitlilikle İlgili Değerlendirmeler

Meraların yönetimi ve iyileştirilmesi, günümüz ve gelecek nesiller için sürdürülmesi ve korunması oldukça önemlidir. Mera çalışmaları genellikle mevcut mera durumunun belirlenmesiyle başlar. Bu nedenle 2008 yılında Kırıkkale – Akçaağaç ve Sivas - Çelebiler köylerinde mera vejetasyon etüdleri yapılmıştır. Modifiye edilmiş tekerlekli nokta metodu vejetasyon etüdlerinde kullanılmıştır. Araştırma sonuçları Akçakavak’ta (20 etüd noktası) bitki ile kaplı alan oranının %47.10 çıplak alan oranının %52.9 ve Çelebiler’de (21 etüd noktası) bitki ile kaplı alan oranının 69.43, çıplak alan oranının %30.57 olduğunu göstermiştir. Mera sağlık durumu Akçakavak’ta sorunlu Çelebiler’de riskli olarak bulunmuştur. Akçakavak mera vejetasyonunda 73 tür, Çelebiler’de 179 tür sayılmıştır. Mera ıslahı için istenen bitki türleri yeterli düzeyde bulunmuştur. Mera vejetasyonlarının biyolojik çeşitliliğini değerlendirmek üzere Simpson ideksi hesap edilmiştir. Çelebiler meralarının vejetasyon biyoçeşitlilik değeri Akçakavak’tan daha yüksek olmuştur. Sonuç olarak iki köy merasında uygun yönetim ve ıslah teknikleri uygulanması önerilmektedir.

Rangeland Condition, Health and Biodiversity Assessments for Two Rangeland Vegetations in The Central Anatolia Region

Improvement and management of rangelands are highly important to sustain and maintain for nowadays and next generations. The first step in vegetation studies is to determine its current vegetation status. For this reason vegetation surveys were performed on the rangelands of Kırıkkale-Akçaağaç village and Sivas-Çelebiler village in 2008. A modified wheel point method was used for vegetation survey. The results of research indicated that vegetation cover and bare ground were found as 47.10 and 52.90%; 69.43 and 30.57% in Akçakavak (20 survey sites) and Çelebiler (21 survey sites), respectively. The rangeland health class was found unhealthy and risky for rangeland in Akçakavak and Çelebiler, respectively. The 73 species in Akçakavak and 179 species in Çelebiler were counted on rangeland vegetation community. Desired plant species were also found in a satisfactory level for rehabilitation of rangelands. Simpsons’ index of diversity was calculated to evaluate biological diversity of rangelands vegetation. Vegetation biodiversity was higher in rangelands of Çelebiler than that of Akçakavak. As a results it is suggested that proper management and improvement techniques should be conducted for both village rangelands.
