Ces deux derni\u00e8res ann\u00e9es, le changement climatique a eu des effets d\u00e9vastateurs sur les r\u00e9cifs coralliens du monde entier. Dans les Cara\u00efbes, et plus particuli\u00e8rement aux \u00celes du Vent, la temp\u00e9rature de la mer a atteint des niveaux records, d\u00e9passant les 31 \u00b0C. Le niveau de stress thermique, mesur\u00e9 en degr\u00e9s-semaines de chauffage, a atteint 25, ce qui, selon la NOAA, correspond \u00e0 un \u201c\u00a0risque de mortalit\u00e9 quasi totale\u00a0\u201d d\u00fb au blanchissement des coraux.<\/span>

<\/span>Our restoration teams in St Lucia and St Vincent and Grenadines have been doing extensive surveys looking for elkhorn and staghorn survivors \u2013 and it\u2019s not looking good.  The sea has been too rough to survey the windward coasts, so we hope we will find some there when it is calmer. In our nursery in Saint Lucia, we have some surviving elkhorn and staghorn genotypes because we moved them into deeper water, but almost all our outplants and source colonies have died.  To make matters worse, last year\u2019s coral bleaching comes on the heels of the terrible SCTLD coral disease, Category 5 Hurricane Beryl, and the severe bleaching of 2023.<\/span><\/p>\n\n\n

<\/span>Marine scientists across the region are monitoring the situation with shock and almost despair. Some are asking whether coral reefs have passed a tipping point where recovery will not be possible. A regional group of marine biologists supported by the Caribbean Biodiversity Fund have recently set up the Caribbean Coral Health Forum to discuss what the next steps should be to conserve and restore coral reefs.  It is clear that we need to re-evaluate our restoration strategy and consider all options.<\/span>
<\/span>
<\/span>The main aim of coral restoration is to assist corals to adapt to a warmer world. To do this, we need to speed up natural selection by helping the more resilient corals grow and reproduce with a high level of genetic diversity.  The more genetically diverse a population is, the more resilient it is.   A simple rule is to have fragments from at least 35 individual corals taken from different locations to ensure that over 95% of the genetic diversity (allelic diversity) of the population is captured.  The problem facing coral restoration programmes in the Eastern Caribbean is that it is becoming increasingly difficult to find that many surviving colonies within one country. <\/span>
<\/span>
<\/span>More importantly we now need to do what many scientists are recommending and start moving corals from hot areas to cooler areas \u2013 it is called assisted migration.  The Meso-American Reef Complex has shallow waters that are on average 1\u00b0C degree warmer than the Eastern Caribbean during the summer months. The corals there have adapted to warmer conditions and some have even survived 34C!<\/span>
<\/span>
<\/span>Pour la survie des r\u00e9cifs coralliens des Cara\u00efbes, il est d\u00e9sormais crucial que scientifiques et d\u00e9cideurs politiques collaborent afin de faciliter le transfert de coraux par-del\u00e0 les fronti\u00e8res nationales et de contribuer \u00e0 la cr\u00e9ation de p\u00e9pini\u00e8res r\u00e9gionales de g\u00e8nes coralliens dans chaque pays. Les scientifiques doivent \u00e9laborer des protocoles pour minimiser les risques de transmission de maladies. Il est temps d'innover \u2013 et le temps presse.<\/span><\/p>\n\n\n\n
