Carefully framed questions provide the foundation and focus
of monitoring programs. Here are some examples.
1. What is the extent and severity of coral bleaching?
There are several monitoring protocols available
to address this question. You should
choose the option that best suits your available resources
(costs and expertise).
2. How much coral died and/or recovered from the bleaching
event?
Few coral reef monitoring protocols specifically
address this question. One that does provide additional
methods for monitoring coral reef recovery after major bleaching
events is that of the Global Coral Reef Management Network
(GCRMN).
One way to assess how much coral died as a result
of a bleaching event is to do repeated surveys on three
occasions (using one of the methods described above), including:
a baseline survey of coral communities prior to
bleaching;
a survey of the extent and severity of coral bleaching
at the height of the bleaching event (usually one to three
months after the onset of bleaching); and
a survey six months after the bleaching event
to determine how much coral survived or died as a result
of bleaching.
Unless there have been other major disturbances during that
period, the differences in coral communities during and after
the bleaching event should be an indication of the impacts
of bleaching (i.e., what percentage died and recovered).
3. Has bleaching affected coral community composition?
This can be assessed using the survey methods described
in 1 and 2 above, but requires some expertise in identifying
species and/or groups of species (e.g., by growth form).
4. Are there any areas that appear to be naturally resistant
and/or resilient to coral bleaching?
5. What are the socioeconomic impacts of bleaching?
