Greetings,
The attached message is a prologue to a larger document by Dr. Michael P.
Crosby, "South Florida Ecosystem Success Indicator - ll: Improvement of
Coral Reef Conditions." The entire document may be read on the Web at:

Dear Colleagues,
As part of my responsibilities and interests both within NOAA and as a
representative on the South Florida Restoration Intergovernmental Science
Working Group I have drafted the following short description of the
"Ecological Success Criteria" for the improvement of coral reef condition.
This very succinct description is the product of numerous discussions,
meetings and e-mails (most of which began on Jim Hendee's coral listserver
earlier this year). I greatly appreciate the input and ideas that I
received from many of you with expertise in this broad ecosystem. I was
NOT looking for verbose treatise on the subject of what is "healthy"
versus "non-healthy". What I was attempting to do was to identify
specific variables (i.e., biomass, diversity, presence/absence,
physico-chemical, indicator species) that should increase or decrease, and
in what magnitude, in order to say the system is improving in overall
condition. I also want to emphasize that I was seeking criteria to
measure significant improvement, not total restoration (that is another
kettle of fish altogether!)
Some variable that had earlier been suggested (although in many cases
still requiring some degree of being quantitative) are:
- Nutrients and suspended sediments reduced
- Macro algae bloom and coverage decrease
- Increase sea urchin population
- Tortugus shrimp harvests restored to recent historic levels to support a
MSY of 10 million pounds annually
- Increase in population of common snook
- Increase in recruitment of Gray Snapper
- Restoration of larval and juvenile spiny lobster habitat (loggerhead
sponges) to their historic range
- Increase in sighting of jewfish
- Increase in sighting of sea turtles
- An increase in coral cover by 15-20%
- Restore coverage and species composition of seagrasses to mid-1980s
level
- Increase in wading bird, osprey and brown pelican populations
The input of many of you, as well as an initial review (by the Everglades
Partnership and Center for Marine and Environmental Analyses at their
Workshop on Ecological sustainability Criteria for South Florida in April,
1996) of draft ESI criteria developed for the entire South Florida Region
has led to the following ESI for the condition of coral reefs in South
Florida. You will note an absence of criteria pertaining directly to
fishes, birds, turtles, etc and a strong focus on the coral reef itself.
This is in direct response to the recommendations from several of you and
specifically the above mentioned workshop. The more mobile species
associated with coral reefs (Yes, we all know that coral have mobile life
stages, but we are dealing with adults here) are addressed in other
sections of the South Florida Ecological Success Criteria document that
should be available in early December, 1996 from the South Florida
Restoration Intergovernmental Science Working Group. I have asked Jim
Hendee to post this "final draft version" of the Coral Reef Chapter of
that document on the CHAMP Home Page and the coral listserver in order to
get this out ASAP and pre-final publication. I still have time to make
some changes to this Chapter prior to the middle of November, 1996. I
would also be greatly appreciative to hear back from anyone who has any
kind of data sets and monitoring or research sites that can assist with
creating the baseline for either the existing and previous condition of
the identified variables. Please feel free to either send you comments
directly to my internet address or use the coral listserver. And once
again, Many Thanks to all of you who have helped with your comments,
suggestions and encouragement.
Cheers,
Michael
