Dear Dr. Precht:
I apologize to you and others on the list if what I wrote was not clear...I
mean in any way to imply that we should abandon the endangered
species act or any other legal avenue of protection people have struggled
for years to establish in order to embrace what you described as a
"shot gun" approach to coral reef conservation. Further, when I was
referring to the interconnectedness of species in such an ecosystem I was
not only referring to other coral species, but other reef
associated species of plants and animals.
The point on which I was trying generate a professional discussion stems
from ever increasing frustrations in finding "real time" solutions to coral
reef conservation problems. I posed the question...could another more
holistic approach to reef conservation legislation be argued at this
time.......based on what scientists have documented about the
interdependence or interconnectedness of species within this ecosystem?
Am I correct in interpreting your response to this question as "no"
when you wrote:
"Well, I think the data tend to argue against these systems being
interconnected (i.e. tightly integrated) "
By systems, do you mean species within the system? If I am interpreting
this correctly, it contradicts what I understand about the co-evolution of
species within ecosystems and the importance of conserving species
biodiversity. This is of concern to me since this is what I attempt to
convey as a "grass roots" educator to the general public about reef
systems. Please clarify if I am misinterpreting your comment...it may well
have been meant only in relation to Acropora and the lack of data
supporting any connection between the decline of other coral species in
relation to Acropora declines.
Any information you, or anyone on the list can send, is always greatly
Thanks to the Langs who wrote:
"In fact an ecosystem approach to species conservation has been our
theoretical underpinning since about 20 years ago when the Gulf of Mexico
and South Atlantic Fishery Management Councils collaborated on a Fishery
Management Plan for Coral and Coral Reefs. The "management unit" here was
defined as being composed of about 400 species of fire corals, soft corals,
gorgonians, black corals and stony corals. At the time, declaring that its
maximum sustainable yield was "incalculable", and that its principal value
was in "nonconsumptive uses" certainly was an unusual approach to fishery
I had no idea this approach was being taken with any FMP......let alone 20
years ago and plead ignorant!
Dr. Precht also wrote:
"Although I am in agreement with you that both corals and coral reefs need
vigilant protection because they are all at some level of risk, especially
at the hands of man coupled with natural disturbances".
I believe we should, in the face of what may be considered time constraints
on the survival of this ecosystem, carefully scrutinize past conservation
management failures and keep our minds open to innovative and more
practices. Please dont think this statement reflects ignorance about
social pressures which govern reef and fish legislation, however, these
comments come from Puerto Rico where fishermen from the municipal island of
Culebra have been requesting the government establish a Marine Fishery
Reserve since 1980 and although final legislation has been drafted for over
a year and a half...still awaits final approval from the local government.
If the cost to society is the entire ecosystem...maybe we could justify the
discussion of more aggressive or comprehensive management strategies? I
have trouble defining the pursuit of any legislative action as being "a
shot gun approach" as you stated. Legislative channels often take time and
are open for meaningful public participation in the form of public hearings
etc...........at least they are where you live.
Indeed, the broad definition given to coral reef ecosystem in Clintons
order 13089, must be at least some cause for concern to the many "hired
gun" consultants whose job it appears is to protect big business and
government from the added expense of functioning in an environmentally
We should, however, pay close attention and note if even this broad
definition given to coral reef ecosystems can effectively be used to
contribute to the conservation of these marine systems? For example, much
of the money or re-allocation of federal funds associated with this
executive order is being focused on mapping and monitoring. Should we be
concerned that 20 years from now, scientist may be reviewing what may then
be historic information of where the living reefs once were? Should we be
concerned that in 20 years scientists may be discussing how hard they
"tried" to conserve these systems through the rationalization that the
first step must be lengthy mapping and monitoring? Will there be any
satisfaction in clearly and empirically demonstrating that these systems
were in fact destroyed by multiple anthropogenic stressors ?
Do current approaches to coral reef conservation management and associated
fund allocation warrant closer evaluation with respect to their potential
effective contribution toward meeting conservation related objectives given
the rate of system degradation? Could not this money be better spent
addressing, for example, more controversial water quality issues?
