ABSTRACT

Herbaceous species contribute to the largest proportion of the fodder. Despite the profound benefits obtained, anthropogenic disturbances are hindering its development. On the other hand, to ensure the sustainability of herbaceous species, communities and governments have been putting efforts in managing herbaceous species through the establishment of area exclosure (AE). Thus, the main importance of this research paper is to provide information about the role of AE on the restoration of herbaceous species. The objective of this study was to assess the effect of restoration on the herbaceous species following AE established on communal grazing land (CGL). A total of 124 and 73 quadrats of 1×1m² size were laid down at 50 m intervals along parallel transects at AE and CGL, respectively, and data were analyzed by t-test unequal variances using R-software. AE displayed higher plant species richness and diversity than the CGL and showed a significant difference (p<0.001). Similarly, the AE had significantly (p< 0.001) higher forage biomass than the CGL. In general, herbaceous species diversity index and species richness were significantly (p< 0.001) higher in the AE compared to the CGL. The study concluded that effective AE has the potential to enhance the restoration of herbaceous species and hence forage productivity.

摘要

草本物种占饲料的最大比例。尽管获得了巨大的收益，但人为干扰仍在阻碍其发展。另一方面，为了确保草本物种的可持续性，社区和政府已经通过建立区域排泄区（AE）来努力管理草本物种。因此，本研究论文的主要重要性在于提供有关AE在恢复草种中的作用的信息。这项研究的目的是评估在公共放牧地（CGL）上建立AE后恢复对草本物种的影响。总共124个和73个四边形1×1m ²分别在AE和CGL上沿平行样线以50 m的间隔放置大小，并使用R-软件通过t检验不等方差分析数据。AE显示出比CGL更高的植物物种丰富度和多样性，并显示出显着差异（p <0.001）。同样，AE具有比CGL显着（p <0.001）更高的饲料生物量。通常，AE中的草本物种多样性指数和物种丰富度比CGL显着高（p <0.001）。该研究得出结论，有效的AE具有增强草种恢复能力并因此提高牧草生产力的潜力。
