Jennifer, I read your posting and also made another attempt to
penetrate the one posted by CBD. The CBD website provides the list of
82 species but no way to make critical comments. It is an
advertisement directed toward providing additional support for the
listing and CBD. We as scientists should be asking, do we need the
listings, and will it save any of the 82 species?
I also read the list of 6 questions you provided. I was looking
for question 7 which should ask, Why do we need these listings? It
was not there. Your 6 questions seem to be aimed at soliciting
additional ammunition to support listing. That of course is you job.
You conclude with, "If any species are proposed for listing, we will
issue a Federal Register Notice of the proposed rule and solicit
"comments" at that time." I suspect from past experience that when we
reach that stage the decision will have already been made. Further
comments at that time will likely have no effect on the outcome. As I
recall that is what happened with the Acropora listing.
As coral scientists I think we should focus on the basic
question. Is it needed? Is there any scientific basis for listing?
Should we not ask, "how will it save the corals?" My main concern is
on the Atlantic species, especially the Mostastreas, where I have
more than 50 years of observation and research experience. This
Genera is the basic builder of patch reefs in The Florida Keys Marine
Sanctuary (where they are already protected by law) as well as in the
rest of the Caribbean. As you know many of these corals in the
Sanctuary were killed, or highly stressed, in the recent January,
2010 cold spell. Would listing have prevented that from happening?
The cold spell in 1969/70 killed 80 percent of these same species at
Hens and Chickens reef (now a SPA) and their death was well
documented. The data was published and remains uncontested (Hudson et
al 1976). Again no amount of legal protection would have prevented
that mortality. We also know that the cold spell of 1977 (when it
snowed in Miami) wiped out the vast majority of Acropora at Dry
Tortugas. That mortality was well documented, (Davis 1982 and Porter
et. al 1982). Would listing have saved those corals? I won't go into
hurricanes. USGS reef coring at Tortugas demonstrated that Acropora
had never been a major reef builder there during the past 5,000 years
(Shinn et al 1977 and Shinn and Jaap 2005). Nevertheless after it was
listed as threatened the Tortugas was classified as "critical
habitat" for Acropora. Geologic history assures us that it never was
a significant reef builder there in the past thus indicating it will
not be in the future. So what did listing accomplish? I might also
mention the Caribbean-wide demise of both Acropora and Diadema that
peaked in 1983 and 84. Would listing have saved them? The answer of
course is no.
The hidden agenda that has recently emerged from the closet is
Co2 rise and possible acidification, a highly politicized issue as
everyone is aware. The fact is that if all Co2 emissions were stopped
tomorrow it would likely take about 50 years to see a reduction in
atmospheric and oceanic Co2 levels. It is also evident that we will
not be free of Co2 emissions for a very long time because we
presently get only about 3 percent of our energy from combined solar,
and wind. Reduction of Co2 will necessarily come very gradually. In
50 yrs we will likely be running out of fossil fuels to burn so
reduction in these emissions will come regardless.
Besides the effects of reduced water temperature it is well
established that in the late 1980s the major killer of Montastrea was
water borne black band disease. The occurrence of black band disease,
along with bleaching, is well documented. Bleaching usually did not
kill but black band did. Black band disease killed at least 90
percent of the 200-year-old Montastrea heads at Carysfort Reef which
until the late 1970s was one of the most prolific reefs in the
Sanctuary. Carysfort even survived construction of the lighthouse in
1850 and the periodic blasting that kept the supply channel clear of
coral growth. Black band disease also killed Montastrea species
throughout the Caribbean. Its exact cause (i.e. the source of the
pathogens) has never been identified, especially around uninhabited
island in the eastern Caribbean where sewage can not be blamed. If we
actually knew the source of such a wide-spread pathogens listing
would make some sense. Without knowing the major cause of Montastrea
death we clearly do not know what to protect it from or how to do so.
Clearly the listing of these species will have no effect on
preserving these Atlantic species. I suspect the same is true for
many in the Pacific but I am not well versed in Pacific corals
although the politics are probably the same. So, one has to ask one
more time, what is the motive for listing? What is the hidden agenda?
Is it just a "feel good" action? Will it fill the coffers of
attorneys at CBD or is the motive to expand NMFS, or both? Common
sense shows that listing will not save these corals. I think I
partially answered the 6 questions but not in the way intended. So
where are we? Why is NMFS and the CBD appear to be soliciting only
information that will further aid the adoption and passage of
additional laws and regulations that will not save corals in our life
times, or our children's, lifetime? Beware of the law of unintended
consequences. Gene
