Coral Health Index (CHI): measuring coral community health.

There is a new tool for assessing coral healthwhich has just been released by Conservation International (CI) and is available for download free on an IUCN website (International Union for the Conservation of Nature). I find it very easy to read and understand, and this appears to me to have widespread potential for applicability and use around the world to get a much better idea of how our reefs are doing. I can’t wait to try it out on reefs near me and see how they rate (I have a guess, but still it will be fascinating to see). Cheers, Doug Fenner
