Change of Sheep Transhumance in South of East Europe

在过去自己的研究成果的基础上，在2012财政年度研究了东欧南部地区羊群转移的变化。罗马尼亚在1989年实行社会主义政权后，土地退化十分严重。在转向自由市场体系后，绵羊头数减少，土地退化得到缓解，特别是在2005年之后。自2007年加入欧盟以来，绵羊一直通过卡车或货车转移到冬季牧区。夏季迁移到山脊地区夏季牧场的羊头数急剧减少。近年来已经观察到树木对山脊地区草原的入侵，因此，在过去的三年里，草地的可持续管理应该是重要的。

A change in the transhumance of sheep in the southern part of East Europe has been studied by fiscal 2012, based on the own research results in the past. In Romania, land degradation was serious after undergoing the Socialist Regime in1989. After shifting to free market system, numbers of heads of sheep decreased and accordingly, land degradation was mitigated particularly after 2005. After joining EU in 2007, sheep have been moving to the winter ranges by trucks or freight cars. The numbers of heads of sheep to move to the summer pasture on the mountain ridge areas in summer have been decreasing drastically. That invasion of trees to the grasslands on the mountain ridge areas have been observed in recent years and therefore, sustainable management of the grasslands should be important in the future, has become clear over the past three years.
