Lesotho has only one wetland designated as a Ramsar site, found at Letšeng-la-Letsie, which is located within the Maloti-Drakensberg region. Despite its designation as a wetland of international importance, little is known about its ecology and biodiversity. Information on wetland biodiversity is crucial for monitoring and conservation planning. This study investigated the vegetation-environment relationships in the Letšeng-la-Letsie Wetland, Lesotho. Vegetation and environmental data were collected using the Braun-Blanquet approach and standard methods, respectively. The data were analysed using cluster analysis and ordination techniques. The study recorded a total of 68 plant species from 50 genera and 23 families in the wetland, with Cotula paludosa, Eragrostis caesia, Haplocarpha nervosa and Trifolium burchellianum as some of the most dominant species. Three distinct plant communities were described: Potamogeton pusillus–Ficinia cinnamomea, Helichrysum glaciale–Eragrostis caesia and Cotula paludosa–Trifolium burchellianum. The communities and species richness recorded revealed high diversity in this wetland when compared to similar wetlands within the Maloti-Drakensberg region. Ordination revealed that species diversity and the plant communities are mainly influenced by altitude, inundation depth, mottling depth, longitude and various edaphic attributes (potassium, total organic carbon, sodium and cation exchange capacity). This study provides the baseline information, which is essential for planning, monitoring and managing this wetland of international importance. In addition, the presence of introduced invasive species suggests the need to practically protect this wetland by implementing the developed management strategies. This will ensure the conservation of biodiversity, sustainable ecosystem service delivery and compliance with the Ramsar Convention requirements.

莱索托只有一处湿地被指定为拉姆萨尔湿地，位于马洛蒂-德拉肯斯堡地区的 Letšeng-la-Letsie。尽管它被指定为具有国际重要性的湿地，但对其生态和生物多样性知之甚少。关于湿地生物多样性的信息对于监测和保护规划至关重要。本研究调查了莱索托 Letšeng-la-Letsie 湿地的植被-环境关系。植被和环境数据分别使用 Braun-Blanquet 方法和标准方法收集。使用聚类分析和排序技术分析数据。本次研究共记录到湿地植物23科50属68种，其中草木、Eragrostis caesia、Haplocarpha nervosa和Trifolium burchellianum作为一些最主要的物种。描述了三个不同的植物群落：Potamogeton pusillus-Ficinia cinnamomea、Helichrysum glaciale-Eragrostis caesia和Cotula paludosa-Trifolium burchellianum. 与 Maloti-Drakensberg 地区的类似湿地相比，记录的群落和物种丰富度显示该湿地具有高度的多样性。排序显示物种多样性和植物群落主要受海拔高度、淹没深度、斑驳深度、经度和各种土壤属性（钾、总有机碳、钠和阳离子交换能力）的影响。这项研究提供了基线信息，这对于规划、监测和管理这片具有国际重要性的湿地至关重要。此外，外来入侵物种的存在表明需要通过实施已制定的管理策略来切实保护这片湿地。这将确保保护生物多样性，
