需要采取紧急行动，阻止世界海草草甸的流失，优先保护它们，并认识到它们提供的一系列生态系统服务。持续下降的原因很复杂，受到一系列跨部门力量的推动，解决办法因此难以概念化。在它们的大部分范围内，海草草甸主要是由海洋被子植物组成的潮间带至潮下底栖动物栖息地的软沉积物。海草占据了全球六个不同的生物区域，形成了世界上最广泛的栖息地之一，分布在除南极洲以外的所有大陆的浅海水域。目前记录的分布包括12.5万平方公里的海草草甸；然而，一些估计表明，它们可以覆盖多达60万平方公里的沿海海洋（Duarte et al. 2010）。海草草甸为人类提供了多种生态系统服务，但它们仍在减少，在保护议程上基本上被边缘化（north等人，2006；Duarte等人，2010；Cullen-Unsworth等人，2014）。在这里，我们简要概述了用于提高海草草地恢复力的成功策略，并提出了“一口大小”的行动，以帮助各种利益相关者采取实际步骤，帮助扭转我们的海草草地的衰落。
Urgent action is required to stem the loss of the world's seagrass meadows, prioritize their protection and recognize the array of ecosystem services (ES) that they provide. The reasons for continued decline are complex, driven by an array of cross-sectoral forces with solutions consequentially difficult to conceptualize. Across most of their range, seagrass meadows are mostly soft sediment intertidal to subtidal benthic habitats comprised of marine angiosperms. Seagrasses occupy six distinct bioregions across the globe and form one of the world's most widespread habitats in shallow coastal waters found on all of the world's continents except Antarctica. Current documented distributions include 125 000 km2 of seagrass meadows; however, some estimates suggest they could cover up to 600 000 km2 of the coastal ocean (Duarte et al. 2010).Seagrass meadows provide multiple ecosystem services to humanity, yet they remain in decline and largely marginalized on conservation agendas (Orth et al. 2006; Duarte et al. 2010; Cullen-Unsworth et al. 2014). Here, we provide a succinct overview of evidenced successful strategies used to improve the resilience of seagrass mead-ows and propose'bite-sized'actions to assist a variety of stakeholders in taking practical steps to help reverse the decline of our seagrass meadows.
