Abstract

DOI: 10.26650/forestist.2018.396995Turkey, which is located in an ecological transition zone between subhumid Southern Europe and the arid Middle East, has a long history of land use and civilization. Pressure from expanding human populations, intensified animal production, and transhumant movements in particular, are leading to the complete denudation of many areas of central Turkey (Central Anatolia), with soil erosion emerging as the primary concern. A mountainous topography and semiarid climatic conditions exacerbate the threat of soil erosion and have limited the success of efforts to restore degraded lands. Although afforestation efforts have increased, rangeland areas dominated by shrub and grass species have decreased. Remnant rangeland areas continue to experience overgrazing and severe losses in productivity. Forest remmants and archeological studies indicate that, due to human use, Central Anatolia has lost its original native vegetation, including pine and oak species, and has assumed anthropogenic steppe characteristics. For this reason, the restoration emphasis has been on tree species, without any consideration for shrub or grass species that could help to stabilize soils in denuded and degraded landscapes. In this article, we discuss the socioeconomic and environmental limitations of the natural revegetation of rangeland areas, and the need for restoration efforts with a focus on shrub and grass species in areas vulnerable to high rates of soil erosion.

Özet

DOI: 10.26650/forestist.2018.396995Çok uzun ve eski bir arazi kullanım tarihine ve uygarlaşmaya sahip Türkiye, yarı nemli güney Avrupa ile kurak Ortadoğu arasında geçiş zonunda yer almaktadır. İnsan nüfusu ve hayvansal üretim artışının yaratttığı baskı, özellikle yayla yaklaşımı, erozyona sebep olarak İç Anadolu’da vejetasyonun kaybına ve arazinin çıplak kalmasına yol açmaktadır. Dağlık topoğrafik yapı ve yarıkurak koşullar toprak erozyonu tehdidini hızlandırmakta ve bozuk alanların restorasyonunun başarılı olmasını kısıtlamaktadır. Ülkemizde ağaçlandırma faaliyetleri artarken, otsu ve çalı türlerinin baskın olduğu mera alanları azalmıştır. Mevcut mera alanları sürekli otlatılmaya maruz kalmakta ve verimlerinde kayıplar meydana gelmektedir. Orman kalıntıları ve arkeolojik çalışmalar, İç Anadolu’nun insan kullanımından dolayı içerisinde çam ve meşe türlerinin de yer aldığı doğal vejetasyon örtüsünü kaybettiğini ve antropojen step özelliği kazandığını göstermektedir. Restorasyon çalışmalarında ağırlık, bozuk ve çıplak alanlardaki toprakları stabil hale getirecek çalı ve otsu türler yerine ağaç türlerine verilmektedir. Bu makalede, mera alanlarının doğal çalı ve otsu türlerle bitkilendirilmesini kısıtlayan sosyo-ekonomik ve çevresel faktörler açıklanarak yüksek derecede erozyona uğrayabilecek alanlardaki otsu ve çalı bitki türlerine restorasyon faaliyetlerinde duyulan ihtiyaç konusu tartışılmıştır.
