Seagrass are an important marine ecosystem of the Fiji Islands. We confirm six seagrass species from the archipelago and defined five broad categories of seagrass habitat. We report, with high confidence, seagrass meadows covering 59.19 km² of Fiji's shallow water habitats from literature and this study. Long-term monitoring of seagrass abundance, species composition, and seed banks at eight sentinel sites, found no long-term trends. Examination of key attributes that affect seagrass resilience identified meadows as predominately enduring and dominated by opportunistic species which had moderate physiological resistance, and high recovery capacity. We examined threats to Fiji's seagrass meadows from extreme climatic events and anthropogenic activities using a suite of indicators, identifying water quality as a major pressure. Based on these findings, we assessed existing protections in Fiji afforded to seagrass and their services. This understanding will help to better manage for seagrass resilience and focus future seagrass research in Fiji.

海草是斐济群岛的重要海洋生态系统。我们确认了来自群岛的6种海草物种，并定义了5种主要的海草栖息地类别。我们充满信心地报告，海草草甸覆盖59.19 km ²文献和这项研究对斐济浅水生境的描述。长期监测八个哨兵点的海草丰度，物种组成和种子库，没有长期趋势。对影响海草抗逆力的关键属性进行检查后，发现草地主要是耐久的，并由具有中等生理抗性和高恢复能力的机会性物种主导。我们使用一系列指标检查了极端气候事件和人为活动对斐济海草草甸的威胁，确定水质是主要压力。基于这些发现，我们评估了斐济对海草及其服务的现有保护。这种了解将有助于更好地管理海草的适应力，并将重点放在斐济未来的海草研究上。
