近日，一种曾被认为在广州地区消失长达60年的珍稀水生植物——飞瀑草（学名：Polypleurum sinense），在广州市从化区的溪流中被重新发现。这一发现不仅为生物多样性保护带来希望，也凸显了当地生态环境持续改善的成效。飞瀑草是一种对水质要求极高的沉水植物，通常生长在清澈、流动、富含氧气的山涧溪流中。由于上世纪中叶以来城市化加速、水体污染和河道改造，其栖息地遭到严重破坏，导致该物种在1960年代后在广州再无确切记录，一度被认为已在本地灭绝。此次由科研人员与环保志愿者联合开展的野外调查中，团队在从化一处水质优良、人迹罕至的溪谷中意外发现了成片的飞瀑草种群。经专家鉴定确认，这是近60年来广州首次正式记录到该物种的自然分布。专家指出，飞瀑草的重现是生态系统健康的重要指标，说明当地水源保护和生态修复工作初见成效。未来，相关部门计划对该区域实施就地保护，并开展种群监测与人工繁育研究，以防止这一珍稀物种再次消失。
Recently, a rare aquatic plant known as ‘Feipu Grass’ (scientific name: Polypleurum sinense), which had been considered locally extinct in Guangzhou for nearly 60 years, has been rediscovered in a stream in Conghua District, Guangzhou. This exciting find not only offers hope for biodiversity conservation but also highlights the positive results of ongoing local environmental restoration efforts.Feipu Grass is a submerged aquatic plant that thrives only in clear, fast-flowing, oxygen-rich mountain streams—conditions extremely sensitive to water quality. Due to rapid urbanization, water pollution, and river modifications since the mid-20th century, its natural habitat was severely degraded, leading to no confirmed sightings in Guangzhou after the 1960s and raising fears of local extinction.During a joint field survey conducted by researchers and environmental volunteers, a healthy population of Feipu Grass was unexpectedly found in a remote, pristine valley in Conghua with excellent water quality. Experts have confirmed this as the first verified record of the species’ natural occurrence in Guangzhou in nearly six decades.Scientists emphasize that the reappearance of Feipu Grass serves as a strong indicator of ecosystem health, reflecting the success of recent watershed protection and ecological rehabilitation initiatives. Authorities now plan to implement in-situ conservation measures, along with population monitoring and propagation studies, to safeguard this rare species from disappearing again.
