《海草床公众监测野外实用指南》由海南省海洋与渔业科学院和德国莱布尼茨热带海洋研究中心等单位或组织的海草研究学者编写。海草是一种非常独特的生活在近海区域的被子植物，常在沿海潮下带形成广大的海草床，对海洋生态环境发挥着极其重要的作用，更维系着人类的生存。但近年来，由于人类对近海海域频繁的干扰活动，海草栖息地环境不断地恶化，种类和分布面积也在不断地减少，保护海草资源迫在眉睫。随着海草保护意识的提升，一些政府、科研部门和民间组织开始对海草投入更多的研究和保护行动，并利用公众科学的方式让公众参与到海草床的生态监测中来，因此，需要建立和完善适合公众参与的海草床监测方法。编写组根据多年的海草调查与研究经验，结合近年来在海南岛开展公众监测的实践，并借鉴国际上比较成熟的方法，编写了面向公众的海草床监测指南。

本指南中对海草进行了科普介绍，给出了海草鉴别方法，介绍了海草床生态监测的流程、所需材料和设备、监测与记录方法以及注意事项。本书可以为社会公众提供一份开展海草床监测的实用宝典，有助于推动公众了解海草、关注海洋保护，并参与到保护行动中来。
