it would be commendable to develop a coral reef on the southern island of Pulau Hantu, but moving corals from other reefs to the island would be something else.  
   
  I assume that you will not transferring just small pieces of corals, but considerably large ones. Is it possible to remove corals from an reef area without destroying its habitat?   While it will improve the lagoon enclosed by Pulau Hantu by putting coral reefs, the project might destroy those existing reefs where the corals will be sourced.  As we know, corals grow by centimeters annually. If it will include moving of corals from other reef, it might render the project to be zero-sum in the context of coral reef system. 
   
  I guess you can improve Pulau Hantu by not significantly disturbing other coral reef habitats...
   
  thanks...

Dear listers,

I came across this article from Singapore's national news agency's website recently, and would like to ask if anyone here has experience with this type of development. What was the outcome, and what are the issues involved? Another article from the newspaper stated that a 'simple sand filtration system' will 'eliminate most of the sediment from the water flowing into the lagoon, creating a clear water habitat.'

Though Singapore has undergone a lot of coastal development and visibility averages around 2m most days, there's plenty of marine life left here, including 197 species of scleractinian corals, so I'm loath to see anything untoward happen to them.

Any responses appreciated. Thanks in advance!

Regards,
Tse-Lynn

Singapore Underwater Federation to build coral reef at Pulau Hantu 
By Sharon See, Channel NewsAsia 

SINGAPORE : Divers may have every reason to rejoice. The Singapore Underwater Federation is looking into developing a coral reef on the southern island of Pulau Hantu. 

Contrary to common belief, Singapore has natural reefs on its offshore islands. 

And the Singapore Underwater Federation is planning an ambitious project, called NOAH for Nurturing Our Aquatic Heritage, which aims to build a coral reef in the lagoon enclosed by Pulau Hantu. 

They are also planning to move corals from other reefs to the island. 

Mr Sydney Chew, Member of Singapore Underwater Federation, says: "Everybody that's involved in this project, from the engineers to the scientists, as well as conservationists have said it's doable, so I believe it is very possible that we can get this project on the road." 

For the next few months, they will first conduct studies on the reefs around Pulau Hantu with a budget of $100,000. 

Dr Geh Min, President of the Nature Society, says much can be done in marine conservation, and the young should be roped in to learn this lesson. She says: "What I hope is that as the project proceeds, young Singaporeans will not be just spectators, they can actually participate. I think this is very important. If you want to use nature as a teacher, taking a specimen into a classroom is very different from taking the student going out into a nature area. " 

Project NOAH is expected to be completed by 2008.

Subject: [Coral-List] Bleaching Havens

I was wondering if people have investigated ways to protect small areas of
reef from warm water bleaching events. We were recently in the west Indian
Ocean and were quite surprised at how slowly the reefs are recovering from
the '98 bleaching event - at least by our (GBR) standards. We attributed
this slow recovery to the severity of the bleaching (95% + in many places)
and the isolated nature of the reefs - presumably this would have meant that
larval supply available for recovery was initially very low. In many places
for example, all the Acroporas we saw were post-98 recruits. Given this slow
recovery it begs the questions: (a) what if there's two such events within
a few years (b) have there already been local extinctions and (c) can
anything be done to get a faster rate of recovery? 

I understand that warm water bleaching coral mortality can sometimes be
reduced by reducing solar irradiation? If so it would be relatively "easy"
to shade small areas of reef for short periods of time during the warm water
event using a plastic fabric that is used in greenhouses (ironic!) and dam
covers. The fabric is light, inexpensive, tough, it floats and is easily
welded or sewn - fitted with air pockets it would be quite possible to make
a portable, floating cover which could shade several hundred square meters
of reef for short periods. Not sure if this would work (it might make it
hotter!!) but some type of 'haven' could provide a source of recruits/
larvae- speeding recovery and possibly reducing localised extinction of
rarer species in isolated reef systems.

Greetings,

It is with mixed emotions that I must announce that our long time
colleague and friend, Louis Florit, will be leaving NOAA and the Coral
Health and Monitoring Program (CHAMP)--which he helped to start back in
1992--as of May 3, 2006. Louis was the original architect of
NOAA/AOML's very first Web Page, the very first coral reef-related Web
page (the CHAMP Page), and the programmer for setting up the original
Coral-List. Louis will be the Director of Information Technology at
Education Connection in Boca Raton, Florida, and I know he will be a
good one. I really hate to see him go, but I wish him well.

By the way, Louis isn't walking away from coral reefs and
information technology. He has assured me he has some great Outreach
surprises for us all in the coming year.

Happy Trails, Louis!

Cheers,
Jim Hendee

Hi Apul,
In some places where there are currents, one could consider sinking a 
ship that would actr as a foil to direct water from deeper depths up 
into the shallow reef areas. For example, why not sink an aging aircraft 
carrier with its flight deck oriented to direct an upwelling event from 
say 50-90 meters?

Dear All -

Last spring, NOAA Fisheries Service published a proposed rule to list 
elkhorn /(Acropora palmata) /and staghorn /(Acropora cervicornis) 
/corals as threatened under the Endangered Species Act (ESA). Pending a 
final determination on this rule, NOAA Fisheries is sponsoring 
stakeholder input workshops throughout South Florida, the Florida Keys, 
Puerto Rico, and the U.S. Virgin Islands (see below for dates, times, 
and locations) to collect information concerning the conservation of the 
species. These workshops are meant to be constructive brainstorming 
sessions during which NOAA Fisheries will gather as much information as 
possible about activities and programs that involve interaction with 
elkhorn and staghorn corals. Additionally, NOAA Fisheries seeks 
information relevant to the designation of possible critical habitat for 
the species. The information gathered during all seven of the workshops 
will be considered in the development of any future conservation 
measures. These workshops are open to the public and all are invited to 
attend and participate. The full workshop announcement and additional 
information on the proposed rule to list /Acropora/ spp. are available 
at NOAA Fisheries Southeast Regional Office Protected Resources Division 
website: http://sero.nmfs.noaa.gov/pr/protres.htm.
