Can anyone provide me with a sensible definition of the raised coral atoll vegetation type known as 'Makatea' or draw me to a paper / publication (s) describing it? I have found the term is used widely in literature but so far failed to find how this karst ecosystem is defined (beyond the obvious - its the vegetation that colonises a raised (fossil) coral reef - typical of the Pacific) and/or set apart from other karst vegetation associations. I am interested in relation to work I am doing on the Kermadec Islands (South Pacific). Any comments, help appreciated.
