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.
