Effects of traditional range enclosures and seasonality on herbaceous plants biodiversity in southern Ethiopia

A.Angassa  G.Oba  R.B.Weladji  
【摘要】:正Introduction Traditional range enclosures have played important roles in the restoration of herbaceous plant biodiversity in degraded rangelands.In southern Ethiopia,the use of range enclosures has been ongoing for the last three decades due to changes in land use from nomadic to sedentary grazing(Angassa,2007).We sampled six enclosures varied in age from 12-14 years,17-24 years and 26-30 years old representing younger,medium and older age categories,respectively.The adjacent rangelands were continuously grazed.
