Restoration of natural habitats plays an important role in nature conservation. After 30 years of efforts to restore species-rich floodplain meadows, most of which had been lost to alternative land uses during the preceding half century, the extent and level of restoration success in the UK remained unknown. A three-year survey of floodplain meadow-restoration projects across England and Wales was completed from 2016 to 2018. It allowed evaluation of restoration progress on 163 sites nationwide. Restoration success was measured by floristic composition, species richness and balance of functional types in plant communities. To identify factors affecting restoration success, their state prior to restoration, restoration technique, site ownership and quality of ongoing management were analysed. The survey revealed that 25 % of restoration sites demonstrated expected success, achieved mainly by private landowners. Restoration failed or showed very poor progress on another 15 % of sites, managed predominantly by public or charitable organisations. The remaining sixty percent of the sites showed some signs of improvement. The degree of restoration success showed no significant correlation to the state of the site prior to restoration, or to the restoration method applied. Ownership of the site and site management both influenced restoration success. The degree of success appeared to depend on the consistency and sufficiency of the restoration management.

恢复丢失的干草草甸：英格兰和威尔士洪泛区草甸恢复项目概述

自然栖息地的恢复在自然保护中发挥着重要作用。经过 30 年努力恢复物种丰富的洪泛平原草甸，其中大部分在前半个世纪因替代土地用途而消失，英国恢复成功的程度和水平仍然未知。2016 年至 2018 年完成了一项为期三年的英格兰和威尔士洪泛区草甸恢复项目调查。它允许对全国 163 个地点的恢复进度进行评估。恢复成功的衡量标准是植物群落的植物区系组成、物种丰富度和功能类型的平衡。为了确定影响修复成功的因素，对修复前的状态、修复技术、场地所有权和持续管理质量进行了分析。调查显示，25% 的恢复地点显示了预期的成功，主要是由私人土地所有者实现的。另外 15% 的站点的修复失败或进展非常缓慢，这些站点主要由公共或慈善组织管理。其余 60% 的站点显示出一些改善迹象。修复成功的程度与修复前的场地状态或应用的修复方法没有显着相关性。场地的所有权和场地管理都影响了恢复的成功。成功的程度似乎取决于恢复管理的一致性和充分性。主要由公共或慈善组织管理。其余 60% 的站点显示出一些改善迹象。修复成功的程度与修复前的场地状态或应用的修复方法没有显着相关性。场地的所有权和场地管理都影响了恢复的成功。成功的程度似乎取决于恢复管理的一致性和充分性。主要由公共或慈善组织管理。其余 60% 的站点显示出一些改善迹象。修复成功的程度与修复前的场地状态或应用的修复方法没有显着相关性。场地的所有权和场地管理都影响了恢复的成功。成功的程度似乎取决于恢复管理的一致性和充分性。
