This work consisted of analysing the impact of protection on the Widou Thiengoly's grasslands structure. Data were collected from three selected sites by the quadrat point methodology, consisting of reading the herbaceous on a 10 m line. These sites were the 2013 defended plot (site A), the 2009 semi‐protected plot (site B) and the unprotected grazing areas or off plot (site C). The results revealed a floristic composition of 45 species, belonging to 34 genera and 17 botanical families. The number of species identified was 28 in site A, 31 in site B and 29 in site C. Despite a certain similarity noted in the number of species, the herbaceous vegetation was more balanced in 2013 plot than in 2009 plot and in off plot where it tended to be homogeneous. The herbaceous cover in October 2015 was 99.8% in the 2013 plot; 98.8% in the 2009 plot; and 96.8% in the unprotected sites. The vertical stratification of herbaceous cover showed a better development at the intermediate strata (between 20 cm and 50 cm) in all the sites except in off plot where small grasses dominated. In this study, protection improved the specific balance, while semi‐protection had a positive effect on the specific richness and growth of the grasses.

保护对费洛维杜·蒂安哥利（Widou Thiengoly）放牧区草地结构的影响

这项工作包括分析保护措施对Widou Thiengoly草原结构的影响。通过四边形点方法从三个选定的地点收集数据，包括在10 m的直线上读取草本植物。这些地点是2013年的防御地块（地点A），2009年的半保护地块（地点B）和未保护的放牧区或非保护区（地点C）。结果表明，该植物区系有45种，属于34个属和17个植物科。确定的物种数量在地点A中为28个，在地点B中为31个，在地点C中为29个。尽管物种数量存在一定的相似性，但2013年地块中的草皮植被比2009年地块和非地块中的植被更加平衡。它趋于均匀。在2013年的地块中，2015年10月的草皮覆盖率为99.8％；在2009年的剧情中为98.8％；在未受保护的站点中占96.8％。草本覆盖物的垂直分层显示，除小草占优势的非耕地外，所有地点的中间地层（20 cm至50 cm）都有较好的发育。在这项研究中，保护措施改善了植物的特定平衡，而半保护措施则对草的特定丰富度和生长产生了积极的影响。
