The GCRMN in Reunion Island, annual monitoring to assess the state of the coral reefs

the global coral reef monitoring network (gcrmn) is an operational network of the international coral reef initiative (icri) aiming to provide the best available scientific information on the status and trends of coral reef ecosystems for their conservation and management. the gcrmn is a global network of scientists, managers and organisations that monitor the condition of coral reefs throughout the world. at reunion island this network was operated by arvam/ird/ecomar from 1998 to 2002, by the marine park from 2003 to 2006 and by the marine reserve of reunion island (rnmr) from 2007 to the present.belt transects are used to assess fish populations and lit (linear intercept transect) to assess coral communities each year. more occasionnally, macroinvertebrate populations are assessed by belt transects.the monitoring is an "expert" type and the identification of taxa is carried out to the species as much as possible. on the other hand, monitoring of fish and macroinvertebrate populations is successively "exhaustive" (all individuals are identified) or "targeted" (only taxa belonging to a list are counted). when the monitoring is "targeted", list of taxa is not always the same.the aim of file attached to this summary is to provide to user of datas (from bd récif database), these different lists of targeted taxa. you will also find a summary of what type of monitoring is carried out each year.

全球珊瑚礁监测网络（GCRMN）系国际珊瑚礁倡议（ICRI）的一个运作网络，旨在提供关于珊瑚礁生态系统现状及趋势的最佳可用科学信息，以支持其保护与管理。GCRMN是一个全球性的科学家、管理者及组织网络，负责监测全球范围内珊瑚礁的状况。在留尼汪岛，该网络自1998年至2002年由ARVAM/IRD/ECOMAR运营，2003年至2006年由海洋公园负责，自2007年起至今由留尼汪岛海洋保护区（RNM）管理。每年，采用带状样带法评估鱼类种群，线性拦截样带法（Lit）评估珊瑚群落。偶尔，还会通过带状样带法评估大型无脊椎动物种群。监测工作采用“专家型”方式，对生物分类单元的识别尽可能精确到物种水平。另一方面，对鱼类和大型无脊椎动物种群的监测则依次进行“详尽”的（识别所有个体）或“靶向”的（仅计数列表中的生物分类单元）。当监测为“靶向”时，生物分类单元列表并不总是固定不变。附于本总结的文件旨在向数据使用者（来自bd récif数据库）提供这些不同列表中的靶向生物分类单元。同时，您还可以找到每年所进行监测类型的大致概述。
