Grassland habitats are particularly threatened in Europe, especially in marginal areas where funds and manpower for their conservative management are limited. Knowledge of the vegetation dynamics is crucial for the timeliness and economy of any conservation actions. However, there is a lack of studies on effective and rapid containment of tall rhizomatous geophytes, such as asphodel (Asphodelus macrocarpus Parl. subsp. macrocarpus), which are particularly active in the earliest stages of the natural vegetation succession. We present an interdisciplinary study carried out on an abandoned semi‐natural grassland (European Union habitat code 6210*) colonized by Asphodel within a Natura 2000 site in the central Apennines (Italy). This experimental trial lasted 4 years (2012–2015) and applied three different treatments (mowing with removal of cut material, mowing without removal of cut material and chopping), compared to the control (abandonment). The results highlight that the disturbance produced by biomass removal has positive effects on biodiversity. In particular, mowing (both with or without removal of cut material) provided better results for restoration of the grassland biodiversity, even over the short term. Chopping is not a viable alternative to mowing, especially because of the risk of eutrophication over time, and the consequent settlement and increase in nitrophilous species.

水仙为主的群落定居草地的恢复策略

草原栖息地在欧洲尤其受到威胁,特别是在边缘地区,用于其保守管理的资金和人力有限。植被动态知识对于任何保护行动的及时性和经济性至关重要。然而,缺乏对高大的根茎geophytes,如水仙(有效和迅速的研究Asphodelus macrocarpus PARL。亚种。macrocarpus),在自然植被演替的最早阶段特别活跃。我们提出了一项跨学科研究,该研究是在Apennines(意大利)中部的Natura 2000场地内,由Asphodel殖民的半天然草地(欧盟栖息地代码6210 *)上进行的。这项实验试验历时4年(2012年至2015年),与对照相比(弃置),采用了三种不同的处理方法(割去有切屑的割草,割去不去割屑的割草和切碎)。结果表明,去除生物质产生的干扰对生物多样性具有积极影响。特别是割草(无论是否去除割草物),即​​使在短期内,也为恢复草地生物多样性提供了更好的结果。割草不是割草的可行选择,
