[Coral-List] Coral Reef Conservation Preferences

Thanks for that Steve,

We shall see what new realities will emerge out of the present
bleaching crisis, and whether new approaches will finally be taken.  With
the present global heat spike becoming a plateau and therefore possibly the
new baseline temperature (yikes!), and with El Nino normally being more
severe in its second year, there is a distinct possibility that the
Caribbean and Atlantic could experience even greater extremes of heat in
the summer of 2024.   At any rate, there is no such thing as over-reacting
at this point in time.  We need to prepare for coming worst case scenarios,
and to secure as many genotypes of each coral species that remain, and
within the natural environment if at all possible.  Once we take corals to
land-based flowing water systems, where does it go from there?  It's time
to figure that out!   Can they be replanted to nurseries in cooler waters
that are designed to be easily shaded?  For coral reefs like Belize and
Cuba, which have broad shelves and strong thermal gradients, the focus can
more easily be placed on translocating heat adapted corals outwards to
cooler reefs.

There may be some Caribbean reefs where translocation from nearshore to
outer reefs has already been the focus in years past, (whether intentional
or not) and where the corals are presently mostly unbleached and doing
well, and so hopefully the results of these efforts will soon be shared.
Rather than spilling the beans here on locations, it is best to wait until
this is all over, and it should come from the actual people doing the work,
not me.  However, when the waters cool off, while we may breathe a sigh of
relief for what survives, we should be careful to not celebrate too much,
so as to not play into the hands of the media, who could proclaim that
coral reefs are doing just fine!   We must portray the fact that we live in
a rapidly warming world and the best we can hope for is to buy some more
time, assuming that the climate crisis will be solved by massive change in
energy production systems.

In summary, our goal must now morph from that of restoration to that of
keeping all coral species alive and in diverse and reproductive condition,
and basing any outplanting of secnd generation corals on spreading adaptive
potential and lessening extinction risk.

Austin
