River Macrophytes Database

The River Macrophytes Database (RMD) is a Microsoft Access database constructed to house data on the plant communities of rivers in Great Britain and Northern Ireland. It includes data from over 7000 survey sites and is the most comprehensive database of its kind. Data have been collected from all over the UK between 1977 and the present day, following the methods of Holmes et al. (1999). The data held in the RMD are the result of collaborative work across all four statutory nature conservation bodies: Scottish Natural Heritage (SNH), Natural England (NE), Natural Resources Wales (NRW, formerly CCW) and the Northern Ireland Environment Agency (NIEA). The River Macrophytes Database can be downloaded from the JNCC website: https://hub.jncc.gov.uk/assets/0a26368d-400c-44e1-beaf-d4b89b7badcd#extent-detail河流水生大型植物数据库（River Macrophytes Database, RMD）是一款基于微软Access（Microsoft Access）构建的专业数据库，旨在存储大不列颠及北爱尔兰境内河流植物群落的相关数据。该数据库收录了超过7000个调查点位的观测数据，是同类型数据集里覆盖范围最为全面的数据库。自1977年至今，所有数据均严格遵循Holmes等人（1999）提出的调查方法，从英国全境采集。RMD所存储的数据集由四大法定自然保护机构合作完成，分别为苏格兰自然遗产署（Scottish Natural Heritage, SNH）、英格兰自然署（Natural England, NE）、威尔士自然资源署（Natural Resources Wales, NRW，前身为CCW）以及北爱尔兰环境局（Northern Ireland Environment Agency, NIEA）。该河流水生大型植物数据库可从联合自然保护委员会（JNCC）官网下载，下载链接为：https://hub.jncc.gov.uk/assets/0a26368d-400c-44e1-beaf-d4b89b7badcd#extent-detail
